Webb primary mirror alignment goes smoothly – Astronomy Now

Slowly but surely, the 18 hexagonal segments that make up the James Webb Space Telescope’s 6.5-meter (21.3-foot) segmented main mirror are aligned to bring starlight to razor-sharp clarity. After Webb arrived in space on Christmas Day, the segments were only roughly aligned. But using the observatory’s near-infrared camera, NIRCam, scientists …

Astronomers think they just spotted an ‘invisible’ black hole for the first time

To discover such an invisible black hole, the team of scientists had to combine two different types of observations over several years. Astronomers took the first-ever direct image of a black hole in 2019, thanks to glowing material in its presence. But many black holes are actually almost impossible to …
