A stunning new image from the James Webb Space Telescope reveals a cosmic mirage known as an Einstein ring, where the light ...

Astronomers using the James Webb Space Telescope have discovered the most distant quiescent galaxy ever seen – one that had ...

The space telescope's image of a odd-looking spiral galaxy is, in reality, two distant galaxies overlapping each other.

Nicknamed the “Big Wheel,” a giant, spiral-shaped disk galaxy was spotted in an unusually crowded part of the early universe just two billion years after the big bang ...

For a long time, scientists thought that only actively star-forming galaxies should be observed in the very early Universe. The James Webb space telescope now reveals that galaxies stopped forming ...

A particularly high fraction of quiescent galaxies is found among massive galaxies, which are often observed to have ...

One of the first verified predictions of general relativity is the gravitational deflection of starlight. The effect was ...

two distant galaxies overlapping each other. An elliptical galaxy and a spiral galaxy appear as one celestial body as a result of the effects of mass on spacetime, the fabric of the universe.

"Could our galaxy one day experience similar high-energy phenomena that will have serious consequences for the survival of precious life in it?" ...

"This discovery upends conventional wisdom, as such powerful jets are almost exclusively found in elliptical galaxies, not spirals," Suraj Dhiwar, a researcher at the Inter-University Centre for ...
