NASA's new space telescope spotted a 13 billion-year-old galaxy that is much too complex to exist that early in the Universe.
The gigantic galaxies we see in the Universe today, including our own Milky Way galaxy, started out far smaller.
The beginning of the Universe has always been something of a chicken-and-egg problem. Did stars and galaxies form first, with black holes slowly coalescing in their midst? Or did black holes appear before the first galaxies?
If confirmed, these would be the first directly-imaged planets that are similar to the giant planets in our own Solar System, and they would demonstrate that widely separated giant planets like Jupiter survive stellar evolution.
It’s oh-so-easy to be absolutely mesmerized by these spiral galaxies. Follow their clearly defined arms, which are brimming with stars, to their centers, where there may be old star clusters and – sometimes – active supermassive black holes.
An international team of astronomers has detected for the first time H-alpha emission in individual galaxies during the so-called Epoch of Reionization, or cosmic dawn.
Astronomers using the James Webb Space Telescope (JWST) have detected the earliest known black hole. Located more than 13 billion light-years away, it dates to a mere 400 million years after the Big Bang.
Beta Pictoris has been revealed by many telescopes, even Hubble, to be home to the most amazing disk. Over the years the second disc was revealed.
The picture, resembling a glowing blue marble rippling into a black ocean, was funneled through the telescope’s infrared filters to capture wavelengths future space travelers wouldn’t see with the naked eye.
A team using NASA’s James Webb Space Telescope has identified the new record-holder: a tiny, free-floating brown dwarf with only three to four times the mass of Jupiter.
The James Webb Space Telescope has turned its golden gaze to Cassiopeia A, a spectacular, complex, expanding cloud of hot gas billowing out from a star humanity saw go supernova back in the 1670s.
Finding methane in the atmosphere of WASP-80 b provides a good roadmap for how to do it for planets more conducive to life.
The James Webb Space Telescope (JWST) recently looked at WASP-107b, a puffy, strange, hot planet about 200 light-years from Earth.
Astrophysicists working with the James Webb Space Telescope (JWST) have found a surprising amount of metal in a galaxy only 350 million years after the Big Bang.
A recent deep field image from the Webb Space Telescope features two galaxies. These galaxies are remarkable for their distance from Earth, being the second and fourth most distant galaxies ever observed.
