3I/ATLAS was born in the deep freeze – Astronomy Now (opens the original)
Read excerpt
The more astronomers learn about interstellar comet 3I/ATLAS, the colder its birthplace appears to have been. New observations made with the William Herschel Telescope (WHT) on La Palma in the Canary Islands have revealed unusually large quantities of nitrogen in the comet’s gasseous plasma tail. The result suggests that 3I/ATLAS formed at temperatures below about –240°C, far from the star around which it was born. The finding adds an independent line of evidence to earlier studies of 3I/ATLAS,
Roman Space Telescope launches on mission to survey the Universe – Astronomy Now (opens the original)
Read excerpt
Roman lifted off aboard a SpaceX Falcon Heavy rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida at 07:26 local time (12:26 BST) on 30 August. Roman separated from the rocket’s upper stage at 12:58 BST, successfully completing the launch and beginning its journey into deep space. The launch came around nine months ahead of NASA’s original schedule, an unusual achievement for a major space observatory. Roman is now beginning its journey towards the second Sun–Earth Lagrange
JWST’s ‘impossible’ early galaxies may be even more massive than we thought – Astronomy Now (opens the original)
Read excerpt
The James Webb Space Telescope has already found distant galaxies that seem uncomfortably large for the young Universe they are seen in. Now astronomers have discovered evidence that such galaxies may contain even more mass in stars than previously estimated, deepening the mystery. The problem comes from estimating a galaxy’s population of small, faint stars such as red dwarfs. These contribute relatively little to a galaxy’s light, but if there are enough of them they can account for a substant
