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 ...

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

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

Spiral galaxies have a thin, pancake-shaped disk, with a spherical bulge at the center. Within the disk, the brightest stars trace out the characteristic spiral pattern. Elliptical galaxies are ...

Webb captured an Einstein ring formed by a distant galaxy's light bending around a closer one. This rare alignment magnifies hidden galaxies.

But it appears to us (observed in optical or infrared) in projection, either as an ellipse or a spiral. We can measure the ...

A striking new image from the James Webb Space Telescope shows a rare object called an Einstein ring. This shows what appears to be a ring-shaped object in the sky, but is actually created by two ...

Astronomers have uncovered a spiral galaxy nearly a billion light-years away that hosts a supermassive black hole launching colossal jets of energy, something once thought possible only in elliptical ...
