Deep inside a nearby galaxy cloaked in thick clouds of gas and dust, astronomers have uncovered a surprising treasure trove of organic molecules using the James Webb Space Telescope. Peering through ...
A new JWST study finds early galaxies at redshift 6–10 may be nearly as old as the universe at that time. One galaxy even appears older than cosmic age estimates, potentially challenging the standard ...
A distant star system with four super-sized gas giants has revealed a surprise. Thanks to JWST’s powerful vision, astronomers detected sulfur in their atmospheres — a chemical clue that they formed ...
Gas giants are massive worlds made mostly of hydrogen and helium. They lack solid surfaces, and in our solar system, Jupiter ...
If a gas giant planet is big enough to ignite deuterium fusion, it becomes a brown dwarf instead of a planet. But this definition is incomplete and does not tell us how gas giants form or what ...
New observations from NASA's James Webb Space Telescope (JWST) suggest that even extremely massive gas giants — once thought ...
Cosmic rays inside a dense molecular cloud were measured for the first time, helping scientists better understand how stars begin forming.
On rare occasions, officials will admit an error that would have changed the outcome of a game. This was one of those times.
Two ways of measuring how fast the universe is expanding disagree, a puzzle known as the Hubble tension. Tiny magnetic fields ...
The discovery provides new insights into the question, 'how large can a planet be?' An illustration of the HR 8799 system with three of its gas ...
Gas giants are large planets mostly composed of helium and/or hydrogen. Although these planets have dense cores, they don't ...
The James Webb Space Telescope (JWST) will have narrow viewing windows on February 18 and 26 to gather crucial data on the ...
