APOD: 2025 June 30 Б NGC 4651: The Umbrella Galaxy
29.06.2025

It's raining stars. What appears to be a giant cosmic umbrella is now known to be a tidal stream of stars stripped from a small satellite galaxy. The main galaxy, spiral galaxy...

M83: Star Streams and a Thousand Rubies
2.07.2024

Big, bright, and beautiful, spiral galaxy M83 lies a mere twelve million light-years away, near the southeastern tip of the very long constellation Hydra. About 40,000 light-years across, M83 is known as the Southern Pinwheel for its pronounced spiral arms.

NGC 3521: Galaxy in a Bubble
4.05.2022

Gorgeous spiral galaxy NGC 3521 is a mere 35 million light-years away, toward the northern springtime constellation Leo. Relatively bright in planet Earth's sky, NGC 3521 is easily visible in small telescopes but often overlooked by amateur imagers in favor of other Leo spiral galaxies, like M66 and M65.

Arp 94
9.10.2013

This telescopic snapshot records a cosmic moment in the tumultuous lives of large spiral galaxy NGC 3227 and smaller elliptical NGC 3226. Catching them in the middle of an ongoing gravitational dance, the sensitive imaging also follows faint tidal star streams flung from the galaxies in their repeated close encounters.

Exploring the Antennae
27.04.2017

Some 60 million light-years away in the southerly constellation Corvus, two large galaxies are colliding. Stars in the two galaxies, cataloged as NGC 4038 and NGC 4039, very rarely collide in the course of the ponderous cataclysm that lasts for hundreds of millions of years.
