Milky Way

The new composite image, which combines hundreds of photos from the Hubble Space Telescope, shows the Andromeda Galaxy with more than 200 million individually resolved stars.

The James Webb Space Telescope has captured a mid-infrared picture of Sagittarius A*, filling in a long-standing gap in observations..

New research suggests that most of the atoms within the human body likely spent part of their lives drifting beyond the Milky Way on a cosmic "conveyor belt," before eventually returning to our galaxy.

Astronomers have discovered a pair of young stars near the supermassive black hole at the heart of our galaxy. Studying them can offer a rare glimpse into how stars can endure — at least briefly — the immense gravity exerted by such cosmic behemoths.

The James Webb Space Telescope has captured an image of a baby, Milky Way-like galaxy that formed more than 13 billion years ago. This "Firefly Sparkle" galaxy could reveal how our own galaxy evolved.

A shockwave caused by the galaxy NGC 7318b slamming into four other galaxies is akin to a "sonic boom from a jet fighter." Astronomers hope the event will reveal vital secrets about the often-violent evolution of our universe.

A 3D map of our cosmic neighborhood has revealed hot and cold regions as well as an "escape tunnel" from our local bubble.

The number of known galaxies circling the Milky Way is increasing as we develop new powerful telescopes.

The image of Sagittarius A*, the black hole at the heart of the Milky Way, captured by the Event Horizon Telescope.

The first piece of the Euclid space telescope's map of the universe is crammed with 14 million galaxies and 100 million sources of light. The mapping project is now 1% done.
