Has Gaia found missing link in black hole evolution?

Video: 00:00:10 When ESA’s Gaia  spacecraft scanned the Scorpius constellation and its ancient globular star cluster Messier 4, it captured something strange: a huge dark blob at the cluster’s centre, 800 times more massive than our Sun. It is normal for globular clusters to have dark centres made up of many dead stars. But the mass […]

Webb finds water vapor, but from a rocky planet or its star?

Image: Astronomers used the NASA/ESA/CSA James Webb Space Telescope to study a rocky exoplanet known as GJ 486 b. It is too close to its star to be within the habitable zone, with a surface temperature of about 430 degrees Celsius. And yet, their observations using Webb’s Near-Infrared Spectrograph (NIRSpec) show hints of water vapor. […]

Webb reveals early-Universe prequel to huge galaxy cluster

Image: The seven galaxies highlighted in this image from the NASA/ESA/CSA Telescope have been confirmed to be at a distance that astronomers refer to as redshift 7.9, which correlates to 650 million years after the big bang. This makes them the earliest galaxies yet to be spectroscopically confirmed as part of a developing cluster. The […]
