Japanese astronomers report the identification of a new ultra-luminous infrared galaxy (ULIRG) as part of the search for far-infrared-bright but optically faint objects. The newly detected ULIRG, designated AKARI-FIS-V2 J0916248+073034, ...
Using the Visible and Infrared Survey Telescope for Astronomy (VISTA), astronomers have detected a new bright quasar at a redshift of about 6.8. The newly identified quasar, designated VHS J0411-0907, is the brightest object ...
Our universe is capable of some truly frightening scenarios, and in this case we have an apparent tragedy: two stars, lifelong companions, decide to move away from the Milky Way galaxy together. But after millions of years ...

Using VST ATLAS and WISE surveys astronomers have identified two new bright high-redshift quasars. The newly found quasi-stellar objects, designated VST-ATLAS J158.6938-14.4211 and VST-ATLAS J332.8017-32.1036, could be helpful ...
An international team of astronomers has conducted a multi-frequency study of NGC 6744, one of the most Milky Way-like spiral galaxies. The new research, published February 8 in a paper on arXiv.org, identifies radio and ...
