Old and Inactive (in the early universe)

An international team of astronomers has, for the first time, spotted a massive, inactive galaxy from a time when the Universe was only 1.65 billion years old. This rare discovery, made using the world-class W….


Spiral, lenticular and massive

This NASA/ESA Hubble Space Telescope image showcases the remarkable galaxy UGC 12591. Classified as an S0/Sa galaxy, UGC 12591 sits somewhere between a lenticular and a spiral. It lies just under 400 million light-years away…


Lots of dwarfs will make one giant

Computer simulations and theoretical models have shown that clusters of miniature galaxies, some 10- to 1,000 times smaller than the Milky Way, should exist, but proof has been elusive. Detections of dwarf galaxy clusters would…


Megamaser in sight

This galaxy has a far more exciting and futuristic classification than most — it hosts a megamaser. Megamasers are intensely bright, around 100 million times brighter than the masers found in galaxies like the Milky…


90,000+ galaxies in your pocket

For nearly eight years, the VIsible MultiObject Spectrograph (VIMOS) on ESO’s Very Large Telescope (VLT) in Chile has been piecing together a three-dimensional map of galaxies in two patches of the southern sky. A total…


A proto-spiderweb in space

Astronomers studying a cluster of still-forming protogalaxies seen as they were more than 10 billion years ago have found that a giant galaxy in the center of the cluster is forming from a surprisingly-dense soup…


Tentacles in space

New observations from the NASA/ESA Hubble Space Telescope have revealed the intricate structure of the galaxy NGC 4696 in greater detail than ever before. The elliptical galaxy is a beautiful cosmic oddity with a bright…
