Russian astronomers have identified three new luminous blue variable (LBV) candidates in the star-forming galaxy NGC 4736. While one of the three newly found candidates was confirmed to be an LBV, the nature of the remaining ...
Using ESA's XMM-Newton and NASA's NuSTAR space telescopes, a team of astronomers from Germany has detected a new ultra-luminous pulsar in the galaxy NGC 300. The finding of this pulsar, which received designation NGC 300 ...
The most luminous galaxy ever discovered is cannibalizing not one, not two, but at least three of its smaller neighbors, according to a new study published today (Nov. 15) in the journal Science and coauthored by scientists ...

An international team of astronomers reports the discovery of a new giant protocluster of galaxies. The newly found protocluster was identified at a redshift of 5.7, when the universe was about 1 billion years old. The finding ...
A new research recently carried out by astronomers suggests that the galaxy NGC 3256 has substantial amounts of dark matter in its central region. The finding, presented in a paper published October 2 on arXiv.org, might ...
In the northern constellation of Coma Berenices (Berenice's Hair) lies the impressive Coma Cluster— a structure of over a thousand galaxies bound together by gravity. Many of these galaxies are elliptical types, as is ...
