Amid the vast darkness of the Milky Way’s halo, a faint, enigmatic trail of stars has been spotted, one that could rewrite our understanding of the galaxy’s formation. C-19, a newly discovered stellar ...

A close-up on two spiral galactic members of the Virgo Cluster (NGC 4301 on the left, and Messier 61 on the right) as imaged by NSF–DOE Vera C. Rubin Observatory. First look images made by the new ...

NexFuture (July 5, 2026) — The Milky Way, often portrayed as a serene, static collection of stars, is actually a violent, ...

Using ESA's Gaia satellite, astronomers have detected 87 stellar streams associated with globular clusters (GCs) in our Milky Way galaxy. The discovery, which doubles the number of known GC stellar ...

The Vera Rubin Observatory found a stellar stream coming from the M61 galaxy, a spiral galaxy in the Virgo Cluster. It extends for about 50 kpc, or 163,000 light years. The face-on image of M61 comes ...

The Rubin Observatory has revealed an enormous stellar stream today. The structure trails behind galaxy M61 across deep cosmic regions. It stretches roughly 163,000 light years in visible length.

Stellar streams are elongated collections of stars liberated from disrupted globular clusters or dwarf galaxies as they orbit within a host galaxy’s gravitational potential. Their morphology, ...
