If you’re about to experience an Algol eclipse, here’s what you should do. First, equip yourself with a clipboard, pencil, red-filter flashlight, and a watch or smartphone to keep track of time. The clipboard should contain a blank sheet of paper and a copy of the Algol Terrain Chart to the left. Then use the attached chart to select a date and time for an upcoming eclipse. From start to finish, each eclipse lasts approximately 10 hours. Fortunately, Algol is almost at its maximum brightness in the first and last hours of the eclipse. You’ll catch most of the action by starting your sightings three hours before mid-eclipse and continuing for another three hours after.

Get out about 10-15 minutes before this time to adjust your eyes to the dark and familiarize yourself with the location of Algol and the surrounding comparison stars. Their magnitudes are marked in green on the Algol field graph. When you’re ready, make an initial estimate of Algol’s magnitude. Simply find a nearby star whose luminosity is equal to that of Algol and write down the time and magnitude. Don’t worry about accuracy; the data you collect is for your eyes only. Your goal is simply to document the behavior of an eclipse variable. While most visual observers of Algol-like variables make their estimates every 10-15 minutes, you’ll get decent results checking every 20-30 minutes. After going inside, plot a graph of your data using time as the X axis and magnitude as the Y axis. When you connect these points, you will have created a light curve of the Algol eclipse. Pretty cool, huh?

If you only have time for a quick glance, estimate Algol’s magnitude a few hours before an expected low. Then, when it is close to its maximum brightness, repeat at the time of mid-eclipse. You will be amazed at the difference!

If your experience with Algol piques your interest in variable stars, I encourage you to learn more about this rewarding activity. Your best source is the AAVSO website (, where you’ll find a handy guide for beginners and a list of easy-to-watch variables.

‘Astronomical’ energy costs are a concern for sports clubs in the Grantham area as winter approaches Mon, 21 Nov 2022 07:00:00 +0000

Sports clubs in the region have expressed concern over rising energy costs, with some having to dip into money earmarked for long-term projects.

Drastically rising energy bills are impacting sports clubs in the Grantham area, including Kesteven Rugby Club and Harrowby United FC, with the latter boasting electricity bills four times the current rate.

These difficult times come after the financial uncertainties caused by the Covid-19 pandemic since March 2020, putting many independent sports clubs under “a lot of pressure”.

Kesteven Rugby Club, based in Woodnook, Grantham, say their energy costs are currently “astronomical”, but have opted not to raise membership fees.

Club treasurer Kerri Arlando said: “Our energy costs are astronomical at the moment, but as a club we didn’t want to increase membership fees to help cover them because everyone is feeling the pinch in this moment.

“We are looking at alternative energy sources and ways to improve our energy efficiency. This, however, has a ripple effect in other areas.”

Rising energy costs not only impact Kesteven’s short-term strategy, but also impact long-term plans.

“We were saving to upgrade our locker rooms because we currently don’t have separate locker rooms for men and women,” Kerri said.

“It looks like we’re going to have to dip into those funds to enable us to meet our ever-increasing energy costs. It’s a real shame as we are a growing club, especially with the women’s section of Kesteven.”

Harrowby United FC, who play at Dickens Road, described the energy crisis as “another blow to the club”, after two years of uncertainty and declining revenue due to Covid-19.

Amber Kitching, operations manager at Harrowby United, said: “As I imagine with most businesses, rising energy costs are a big concern for us at the moment.

“With heating and electricity costs soaring, we are under a lot of pressure to cover costs that we had not anticipated.

“For example, we see quotes for electricity that are four times higher than the current price. For voluntary sports facilities, this means that we have to increase revenue by the same amount, which is neither easy nor quick. .

“We are also unable to reduce our usage easily, as floodlights are a necessary evil in these circumstances.

“We will continue to monitor the situation and hope that government assistance will be forthcoming. But having come out of an extremely difficult period with Covid, now being affected by this is just another blow for the club.

“We want to develop and grow as a club, but things like this can easily derail those plans.”

An SKDC spokesperson said: “SKDC is continuously reviewing the situation at all premises for which we are responsible.

“Budget proposals for 2023-2024 will be debated as part of the annual budgeting process over the coming months.

Sun-like star discovered orbiting closest black hole to Earth Tue, 15 Nov 2022 18:11:06 +0000

Imagine if our Sun were orbiting a black hole, perhaps spiraling into it. Admittedly, the idea that our relatively normal star could fall into such a trap sounds like the plot of a sci-fi movie. Indeed, of all the black holes astronomers have discovered before, none were known to threaten a Sun-like star.

Instead, black holes tended to be tightly bound to their companion stars, stripping them of matter, which then glows brightly as it accelerates toward its gravitational fate. This swirling accretion disk of stripped matter is why black holes are bright sources of X-rays – and it’s how astronomers typically spot black holes in the first place.

But astronomers have long thought there might be a more insidious population of black hole binary systems that don’t shine brightly and therefore remain hidden. And if those stealthy black holes are out there, then the latest generation of orbiting observatories might be able to spot them.

Now, Kareem El-Badry of the Harvard & Smithsonian Center for Astrophysics in Cambridge and others say they have discovered the first example of such a black hole hidden in data collected by the Gaia spacecraft.

This strange system, called Gaia BH1, consists of a Sun-like star orbiting a tiny, massive object, which El-Badry and his colleagues refer to as a black hole. If confirmed, this black hole would be the closest known black hole to Earth.

The new observations suggest that black hole systems harboring seemingly ordinary stars are likely much more common than originally thought.

3D Map of the Milky Way

The Gaia spacecraft currently measures the positions and distances of over a billion astronomical objects in our galaxy. In this way, he assembles the most detailed 3D map of the Milky Way ever made.

As Gaia moves in its orbit around the Sun, it measures the apparent change in a celestial object’s position relative to the background sky, called its parallax. With a fairly simple calculation, astronomers can then determine exactly how far away this object is.

But every once in a while, Gaia encounters objects moving in different ways, usually because they’re orbiting another object. And earlier this year, El-Badry and his team found such an example in the latest Gaia dataset.

The object in question is an ordinary star roughly the same size, mass, and temperature as our Sun, but it resides about 1,600 light-years away in the constellation of Ophiuchus the Serpentarius. The only strange feature of this star is its wheel motion, which the researchers say is a clear indication that it must orbit an unseen companion every 186 days.

El-Badry and his team set out to characterize the nature of this companion. Based on a detailed series of other ground-based observations, the researchers say the black hole’s putative companion is not visible to any wavelengths. Given this motion, the Sun-like companion must have a mass about 10 times that of the Sun.

It’s too massive for the invisible object to be a neutron star. And if the object were an ordinary star, it would be 500 times brighter than its Sun-like companion. The fact that the central object remains invisible leaves only one conclusion. “We find no plausible astrophysical scenario that can explain the orbit that does not involve a black hole,” they say.

If confirmed, this interesting discovery should rewrite our understanding of both the nature and ubiquity of black holes. Until now, the closest black hole to Earth was about three times as far away.

The existence of Gaia BH1 so close to Earth suggests that such systems must be common. “His discovery suggests the existence of a large population of dormant black holes in binaries,” the authors write in their paper, published Nov. 2 in Royal Astronomical Society Monthly Notices.

Training jigsaw

Gaia BH1 is something of a puzzle: El-Badry and his team are still wondering how he could exist. The problem is that most black holes form from huge supernova explosions that occur when massive stars die.

The researchers say Gaia BH1’s ancestor must have been a supergiant star with a radius much larger than the current separation of the binary system. But a Sun-like star could not have survived under these circumstances during or after a supernova, so Gaia BH1 must have formed some other way. However, the exact way is still unclear.

To better understand the strange Gaia BH1 system, astronomers need to find other examples of hidden black holes. Fortunately, they may not have to wait long. El-Badry and his team are optimistic that “future versions of Gaia will likely facilitate the discovery of dozens more.”

Why ghost particles crashing into Antarctica could change astronomy forever Sat, 12 Nov 2022 22:00:12 +0000

About 47 million light-years from where you’re sitting, the center of a black hole-laden galaxy named NGC 1068 spews streams of enigmatic particles. These are neutrinos – otherwise known as the elusive “ghost particles” that haunt our universe while leaving little trace of their existence.

Immediately after coming into existence, beams of these invisible pieces plunge through the cosmic expanse. They pass bright stars we can see and pass pockets of space full of wonders we have yet to discover. They fly and fly and fly until, occasionally, they reach the South Pole of the Earth and bore underground. Neutrino travel is continuous.

But scientists are patiently awaiting their arrival.

Nestled in about 1 billion tons of ice, more than 2 kilometers (1.24 miles) below Antarctica, is the IceCube Neutrino Observatory. A neutrino hunter, you might say. And when neutrinos transfer their group to the freezing continent, IceCube remains vigilant.

In a paper published Friday in the journal Science, the international team behind the ambitious experiment confirmed they had found evidence of 79 “high-energy neutrino emissions” from where NGC is located. 1068, opening the door to novel — and infinitely fascinating — types of physics. “Neutrino astronomy”, scientists call it.

It would be a branch of astronomy capable of doing what existing branches simply cannot do.

Before today, physicists had only shown neutrinos from either the sun; the atmosphere of our planet; a chemical mechanism called radioactive decay; supernovae; and – thanks to IceCube’s first breakthrough in 2017 – a blazar, or voracious supermassive black hole pointed directly at Earth. A void named TXS 0506+056.

With this new source of neutrinos, we are entering a new era in the history of the particle. In fact, according to the research team, it’s likely that neutrinos from NGC 1068 have up to millions, billions, maybe even trillion the amount of energy held by neutrinos rooted in the sun or supernovae. These are jaw-dropping numbers because, in general, these ghostly fragments are so powerful, yet elusive, that every second billions and billions of neutrinos are moving through your body. You can’t tell.

And if you wanted to stop a neutrino in its tracks, you’d need to fight it with a light-year block of lead – although even then there would be a fraction of a chance of success. Thus, exploiting these particles, NCG 1068 version or not, could allow us to penetrate into areas of the cosmos that would usually be out of reach.

Now what?

Not only is this moment massive because it gives us more evidence of a strange particle whose existence wasn’t even announced until 1956, but also because neutrinos are like the backstage keys to our universe.

They have the ability to reveal phenomena and solve puzzles that we cannot solve by any other means, which is the main reason why scientists are trying to develop neutrino astronomy in the first place.

“The universe has multiple ways of communicating with us,” Denise Caldwell of the National Science Foundation and member of the IceCube team told reporters Thursday. “Electromagnetic radiation, which we see as starlight, gravitational waves that shake the fabric of space – and elementary particles, such as protons, neutrons and electrons spewed out from localized sources.

“One of those elementary particles has been the neutrinos that permeate the universe, but unfortunately neutrinos are very difficult to detect.”

In fact, even galaxy NGC 1068 and its gargantuan black hole are mostly obscured by a thick veil of dust and gas, making them difficult to analyze with standard telescopes and optical equipment – ​​despite years of scientists trying to break through. its curtain. NASA’s James Webb Space Telescope might have a head start in this case due to its infrared eyes, but neutrinos might be an even better way in.

Intended to be generated behind such opaque screens filtering our universe, these particles can carry cosmic information behind these screens, zoom great distances while interacting with virtually no other matter, and provide humanity with pristine and untouched information about the elusive corners of outer space.

“We are very lucky, in a sense, because we can access an incredible understanding of this object,” said Elisa Resconi, of the Technical University of Munich and a member of the IceCube team, of NGC 1068.

ice Cube

In this artistic rendering, based on an actual image from the IceCube lab at the South Pole, a distant source emits neutrinos that are detected under the ice by IceCube sensors, called DOMs.


It is also worth noting that there are many (many) more galaxies similar to NGC 1068 – classified as Seyfert galaxies – than there are blazars similar to TXS 0506+056. This means that IceCube’s latest discovery is, arguably, a bigger step forward for neutrino astronomers than that of the observatory.

Perhaps the bulk of neutrinos scattering in the universe are rooted in NGC 1068 lookalikes. But in the grand scheme of things, neutrino merit is not limited to their sources.

These ghosts, as Justin Vandenbroucke of the University of Wisconsin-Madison and a member of the IceCube team have said, are adept at solving two major mysteries in astronomy.

First, a host of galaxies in our universe have gravitationally monstrous voids at their centers, black holes reaching masses millions to billions of times greater than our sun. And these black holes, when active, blast jets of light from their innards – emitting enough illumination to dwarf every star in the galaxy itself. “We don’t understand how this happens,” Vandenbrouke said simply. Neutrinos could provide a way to study the regions around black holes.

Second, there is the general, but persistent, cosmic ray conundrum.

We don’t really know where cosmic rays come from either, but these strings of particles reach energies up to and beyond millions of times greater than what we can reach here on Earth with particle accelerators built by man like that of CERN.

“We think neutrinos have a role to play,” Vandenbroucke said. “Something that can help us answer these two mysteries of black holes powering very bright galaxies and the origin of cosmic rays.”

A decade to catch a handful

To be clear, IceCube doesn’t exactly trap neutrinos.

Basically, this observatory tells us whenever a neutrino interacts with the ice that envelops it. “Neutrinos barely interact with matter,” Vandenbrouke pointed out. “But they sometimes interact.”

As millions of neutrinos shoot into the icy region where IceCube is installed, at least one tends to collide with a grain of ice, which then shatters and produces a flash of light. IceCube sensors capture this flash and send the signal to the surface, notifications which are then analyzed by hundreds of scientists.


A rendering of the IceCube detector shows the interaction of a neutrino with an ice molecule.

IceCube/NSF Collaboration

Ten years of light flash data has allowed the team to determine roughly where each neutrino appears to be coming from in the sky. It soon became clear that there was a dense region of neutrino emissions located right where the galaxy NGC 1068 is stationed.

But even with such evidence, Resconi said the team knows “now is not the time to open the champagne, because we still have a fundamental question to answer. How many times has this alignment happened? by chance? How can we be sure that the neutrinos are really coming from such an object?”

A diagram of the latest IceCube results on the sky.  It shows where neutrinos appear to come from across the universe and identifies the densest places as sources.

A sky map of the point source scan in the Northern Hemisphere, showing where neutrinos appear to come from across the universe. The circle of NGC 1068 also coincides with the hottest spot in the northern sky.

IceCube Collaboration

So to make it as concrete as possible and to really, really prove that this galaxy spits out ghosts, “we generated the same experiment 500 million times,” Resconi said.

Whereupon, I can only imagine, a bottle of Widow finally popped. Although the hunt is not over.

“We are only beginning to scratch the surface when it comes to finding new sources of neutrinos,” said Ignacio Taboada of the Georgia Institute of Technology and a member of the IceCube team. “There must be many other sources much deeper than NGC 1068, hidden somewhere to be found.”

The Leonids promise to dazzle this year Thu, 10 Nov 2022 19:35:18 +0000

How to better observe

The shower radiant (for the star chart, see Sky This Month on page 29) does not rise until local midnight and will not be highest in your location until dawn. And luckily, pre-dawn viewing hours are the best for meteor viewing, because that’s when your viewing site begins to bob headlong into the flow of debris. So the best way to approach this year’s Leonid Shower is to prepare for a five-day morning vigil from November 16-21.

Imagine the Earth as a car speeding down the highway. Just as insects crash into the front windshield more frequently than the rear windshield, Leonid meteors also appear to crash into Earth’s atmosphere more frequently as our planet rushes through the debris flow of the comet.

Where should you look? While the paths of rain meteors can be traced back to a point on Lion’s Sickle, most appear as streaks of light some distance from that radiant. Shower meteors near or at the radiant may appear as a short, quick flash or a puffing point source. Meteors farther from the radiant will take the form of longer streaks of light. Both are remarkable, so divide your time between looking at the beaming and a bit further.

In the latter case, it is best to focus your attention on an area about 20° to 40° (two to four fist widths) from the radiant and about halfway up the sky, as you will be covering more area. The same advice generally applies to those wishing to image the event.

As a general rule, the farther a meteor is from the radiant, the longer its trajectory. However, it’s important to know where the radiant shower is, as you’ll need to retrace the meteor’s path to make sure any meteor you see isn’t sporadic – a rogue meteor whose path can’t be traced back to you. to a specific source.

A nocturnal treat

I can’t explain enough why these screens are worth it. If November 19 produces anything like the display I saw on the morning of November 16, 1999, it shouldn’t be missed.

That morning, observers at some lucky locations around the world saw a splendid rain of about 250 fireballs per hour falling from the sky. And even if it wasn’t a storm, the grandeur and magnitude of the meteors will forever be etched in my mind, especially since a strange flash through my bedroom window woke me up that night. . Once outside, I saw 30 dazzling fireballs and four more meteors falling from the Sickle of the Lion in 45 minutes.

Even if numbers like that don’t materialize this year, since the Leonids are already known for their brightness, any increase in brightness or numbers will be welcome on November 19th.

Ultimately, while we’re not sure if any of the Leonid 2022 events will shock and visually amaze, it’s best to be prepared for whatever the shower has in store. As always, with meteor viewing, expect the unexpected!

How to watch the last total lunar eclipse of the year | Astronomy Mon, 07 Nov 2022 19:42:00 +0000

Scheduled to take on a copper-red hue in the sky this Tuesday, November 8, the full moon will kick off Election Day with an early morning event of its own – a total lunar eclipse.

The second of the year, the eclipse will begin at 3:02 a.m. ET, with the moon initially darkening during the first hour, and end at 8:50 a.m. ET.

At totality, the stage at which the entire moon is in Earth’s shadow, the moon will take on a dark reddish hue, which is why a total eclipse is also called a blood moon. Skywatchers will be able to see the startling effect starting at 5:17 a.m. ET, according to NASA.

“They’re not that common, so it’s always nice to contact them when you can,” said Dr. Alphonse Sterling, an astrophysicist at NASA’s Marshall Space Flight Center in Huntsville, Alabama. “I think these are great learning devices for people who want to get into astronomy.”

A total lunar eclipse occurs approximately once every 1.5 years on average, with the next total lunar eclipse not occurring until March 14, 2025 – although partial and penumbral lunar eclipses will continue to occur in the meantime. A penumbral lunar eclipse occurs when the moon moves through Earth’s outer shadow, or penumbra, so the visual effect is more subtle.

Those watching the total lunar eclipse will be able to see the curvature of the Earth’s shadow as it begins to slowly swallow the moon completely. At least some of the phenomenon will be visible throughout eastern Asia, Australia, the Pacific, North America and Central America, according to NASA.

Every first full moon in November is called the Beaver Moon in honor of the semi-aquatic rodents. This is the time of year when beavers begin to take shelter after storing their food for the winter, according to The Old Farmer’s Almanac. The moon will peak at 6:02 a.m. ET, the almanac notes.

Visualization of a lunar eclipse

A lunar eclipse occurs when the Sun, Earth, and Moon align so that the Moon passes into Earth’s shadow. Due to this arrangement, unlike a solar eclipse, a lunar eclipse can be enjoyed from anywhere the moon is present overnight. Nearby stars are usually obscured by the moon’s glow, but the moon will be dim enough for the duration of the eclipse for them to be revealed, according to Sterling.

“With solar eclipses you have to be in the right place, but with lunar eclipses it’s not as location-sensitive,” Sterling said.

“All half of the Earth that is at night during the period when the moon is in shadow can see it. So basically it’s available to half the world.”

The same phenomenon that colors skies blue and sunsets red is what causes the moon to turn rusty red during a lunar eclipse, according to NASA. During a lunar eclipse, Earth’s atmosphere scatters sunlight, letting in red, orange, and yellow light and scattering blue light that is typically seen with the moon.

In the eastern United States and Canada, the moon will set before the eclipse ends, so it’s best to look toward the western horizon to see its entirety. Watching a solar eclipse requires eye protection, but you can safely enjoy a lunar eclipse without any equipment – ​​although your eyesight can be improved with binoculars.

“It’s a very good thing about lunar eclipses, in particular. You really don’t need anything but your eyes. The moon is a bright object, so you don’t need a place particularly dark to view the event,” Sterling said. “And the shades, the beautiful red color that you see during the eclipse, you can see anywhere, even in the middle of a city.”

Events remaining in 2022

After the Beaver Blood Moon, this year has another full moon event, according to The Old Farmer’s Almanac. The Cold Moon occurs on December 7.

As for meteor showers, you can currently see the Southern Taurids in the night sky. Catch the peak of these upcoming meteor shower events later this year, according to EarthSky’s 2022 meteor shower guide:

• Northern Taurids: November 12

• Leonids: 17 and 18 November

• Geminids: December 13 and 14

• Ursids: December 22 and 23

Space news: Oldest star in Milky Way with planetary system spotted by UK astronomers | Science | New Sat, 05 Nov 2022 00:01:00 +0000

British astronomers have identified the oldest star in the Milky Way with a confirmed planetary system around it, born more than ten billion years ago. The team of scientists led by the University of Warwick today published their findings in the Monthly Notices of the Royal Astronomical Society, relating to their study of a faint white dwarf 90 light-years from Earth, together with the remnants of its orbiting planetary system.

A white dwarf is a star that has burned all its fuel and lost its outer layers and is now undergoing a shrinking and cooling process.

Billions of years in the future, the Sun itself will one day suffer such a fate.

During the process of a white dwarf collapse, all orbiting planets will be disrupted and in some cases destroyed, with their debris accumulating on the surface of the decaying star.

The team modeled two unusual white dwarfs spotted by the European Space Agency’s Global Astrometric Interferometer for Astrophysics (GAIA) space observatory.

Both were polluted by planetary debris, with one found to be unusually blue, while the other is the faintest and reddest found in the local galactic neighborhood to date.

Using complex instruments from the European Southern Observatory, scientists have concluded that the ‘red’ star WDJ2147-4035 is around 10.7 billion years old, of which 10.2 billion years have passed to cool as a white dwarf.

Debris found in the near-pure, high-gravity helium atmosphere turned out to be from an ancient planetary system that survived the star’s evolution into a white dwarf, leading astronomers to conclude that it was the oldest planetary system around a white dwarf yet discovered in the Milky Way.

The second “blue” star, WDJ1922+0233, was only slightly younger than WDJ2147-4035 and was polluted with planetary debris similar in composition to Earth’s continental crust.

Lead author Abbigail Elms, a PhD student in the Department of Physics at the University of Warwick, said: “These metal-polluted stars show that the Earth is not unique, there are other planetary systems with planetary bodies similar to Earth.”

Some 97% of all stars would become white dwarfs, and their ubiquity meant understanding them was very important, she pointed out.

Ms Elms added: ‘Formed from the oldest stars in our galaxy, cool white dwarfs provide insight into the formation and evolution of planetary systems around the oldest stars in the Milky Way.

“We find the oldest stellar remnants of the Milky Way that are polluted by once-Earth-like planets.

“It’s amazing to think that this happened on the scale of ten billion years, and that these planets died long before Earth was even formed.”

Astronomers can also use the star’s spectra to determine how quickly the metals that had been identified were sinking into the star’s core, allowing them to look back in time and determine the abundance. of each of these metals in the planetary body of origin.

By comparing these abundances to planetary material found in Earth’s own solar system, it was possible to estimate what these planets would have looked like before the star died and became a white dwarf – although in the case of WDJ2147-4035, this proved difficult. .

Ms Elms explained: ‘The red star WDJ2147-4035 is a mystery because the accreted planetary debris is very rich in lithium and potassium and unlike anything known in our own solar system.

“It is a very interesting white dwarf because its ultra-cold surface temperature, the metals that pollute it, its old age and the fact that it is magnetic, make it extremely rare.”

Professor Pier-Emmanuel Tremblay from the Department of Physics at the University of Warwick said: “When these old stars were formed more than 10 billion years ago, the universe was less rich in metals than it seems. is now, because metals form in evolved stars and gigantic stellar explosions.

“The two observed white dwarfs provide an exciting window into planetary formation in a metal-poor, gas-rich environment that was different from the conditions of solar system formation.”
