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…


Finding a new galactic neighbor

An international team led by researchers from Tohoku University has found an extremely faint dwarf satellite galaxy of the Milky Way. The team’s discovery is part of the ongoing Subaru Strategic Survey using Hyper Suprime-Cam….


Count again

Astronomers using data from the NASA/ESA Hubble Space Telescopes and other telescopes have performed an accurate census of the number of galaxies in the Universe. The group came to the surprising conclusion that there are…
