Yale researchers among those who discovered three “ultra-massive” galaxies, which were formed shortly after the Big Bang and ...

Image of three Milky Way-like galaxies and their systems of satellite galaxies. The SAGA survey identified two, six, and nine small satellite galaxies in these three systems respectively.

That's why a manual, by-eye search by University of Arizona astronomer David Sand was needed to discover three faint and ultra-faint dwarf galaxies located in the direction of the spiral galaxy ...

While we have plenty of spiral galaxies, like our own Milky Way, these are only the most common types of galaxies out there. There are still others, like elliptical or irregular galaxies.

An ultra-deep image from the National Science Foundation's Dark Energy Camera reveals a wide variety of galaxies in the unusual Antlia Cluster.

Gemini South’s Gemini Multi-Object Spectrograph (GMOS) captured all three galaxies in exquisite detail. An analysis of the data showed that they appear to be empty of gas and contain only very ...
