Astronomers from the University of Groningen and elsewhere have identified 44 new ultra-compact dwarf galaxies (UCDs). The newly found objects most likely belong to the Fornax Cluster. The discovery is reported in a paper ...
Looking up at the starry sky, the deep Universe appears quiet and mysterious. It is hard to imagine that the ancient dwarf galaxy Enceladus violently collided and was torn apart by our own Milky Way Galaxy, leaving behind ...

Using an amateur 0.14-m aperture telescope, astronomers have observed a nearby spiral galaxy known as M63 (or NGC 5055). The observations identified the presence of five faint dwarf galaxies around M63 and allowed the researchers ...
Nearly 3 billion years ago, a dwarf galaxy plunged into the center of the Milky Way and was ripped apart by the gravitational forces of the collision. Astrophysicists announced today that the merger produced a series of telltale ...

Astronomers from the Special Astrophysical Observatory (SAO) in Nizhnij Arkhyz, Russia, have conducted photometric observations of dwarf galaxies identified by the ALFALFA survey. The results allowed the researchers to determine ...
When a star unleashes as much energy in a matter of days as our Sun does in several billion years, you know it's not going to remain visible for long.
