A new investigation with NASA's James Webb Space Telescope into K2-18 b, an exoplanet 8.6 times as massive as Earth, has revealed the presence of carbon-bearing molecules including methane and carbon dioxide.
NASA's James Webb Space Telescope has followed up on observations by the Hubble Space Telescope of the farthest star ever detected in the very distant universe, within the first billion years after the big bang.
It's called Messier 57, AKA the Ring Nebula, a glowing circle of gas in the constellation of Lyra, some 2,750 light-years from Earth.
This observation suggests exciting avenues of investigation into both the production of cosmic dust and the earliest stellar populations in our Universe, and was made possible by Webb’s unprecedented sensitivity.
In a first, the James Webb Space Telescope (JWST) may have glimpsed a rare type of star that astronomers aren’t even sure exists. These “dark stars” might not have been fueled not by nuclear fusion but by the self-annihilation of dark matter.
NASA recently released a stunning new image of Saturn, depicting the planet's rings shining brightly against the blackness of space. The powerful space telescope has now captured all four gas giants in our solar system.
The James Webb Space Telescope has discovered the four most distant galaxies ever observed, one of which formed just 320 million years after the Big Bang when the universe was still in its infancy, new research said on Tuesday.
In a molecular cloud called Chamaeleon I data from the telescope has revealed the presence of frozen carbon, hydrogen, oxygen, nitrogen, and sulfur – elements vital to the formation of atmospheres and molecules.
