The James Webb telescope found ‘Green Pea’ galaxies in the early universe
Galaxies that helped transform the early universe may have been small, round and green. Astronomers using the James Webb Space Telescope have spotted “Green Pea” galaxies dating to 13.1 billion…
Methylated gases could be an unambiguous indicator of alien life
SEATTLE — Attention alien hunters: If you want to find life on distant planets, try looking for signs of toxic chemical cleanup. Gases that organisms produce as they tidy up…
The James Webb Space Telescope wasn’t the only big space news in 2022
While the stunning images from the James Webb Space Telescope captured space fans’ attention this year, other telescopes and spacecraft were busy on Earth and around the solar system (SN…
The James Webb telescope is getting glimpses of small, far-off planets
BALTIMORE — When the James Webb Space Telescope was first dreamed up, exoplanets hadn’t even been discovered yet. Now the observatory is showing astronomers what it can learn about planets…
The first planet found by the Kepler space telescope is doomed
