The El Gordo galaxy cluster moves faster than you might think

The second- and fourth-most distant galaxies ever seen (UNCOVER z-13 and UNCOVER z-12). The galaxies are located in Pandora’s Cluster (Abell 2744), show here as near-infrared wavelengths of light that have been translated to visible-light colors.

JWST uncovers some of the most distant galaxies yet seen

It may not look like much, but capturing photons from the distant quasar 3C 273 is one of the most awe-inspiring observations you can make with a small telescope.

Euclid telescope releases first awe-inspiring images in dark universe hunt

This artist’s impression shows how ULAS J1120+0641, a very distant quasar powered by a black hole with a mass two billion times that of the Sun, may have looked. This quasar is the most distant yet found and is seen as it was just 770 million years after the Big Bang. This object is by far the brightest object yet discovered in the early Universe.

What we’ve learned in 60 years of studying quasars

A galactic collision of two galaxies which began more than 300 million years ago, NGC 520 is actually made up of two disk galaxies which will eventually merge together to form one larger, more massive system. NGC 520 was discovered by William Herschel in 1784 and is one of the largest and brightest galaxies in the Siena Galaxy Atlas.
