The contributions from NASA’s Chandra X-ray data provide the blue and white flickering lights from young stars and the green pine needles come from the optical data collected by the National Science Foundation’s WIYN Observatory.

open and globular star clusters

Galaxies, Stars

Why are open clusters and globular clusters found in different places?

Billions of years from now, the night sky will glow with stars, dust, and gas from two galaxies: the Milky Way, in which we live, and the encroaching Andromeda Galaxy (M31). Credit: Lynette Cook for Astronomy magazine.

Dishes of the Karl G. Jansky Very Large Array in New Mexico line up beneath the starry sky. Radio waves are just one of the numerous signals from space that comprise the soundtrack of the cosmos.

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.
