Using Karl G. Jansky Very Large Array (JVLA), astronomers have performed multifrequency radio observations of the radio galaxy MRC 2011-298. Results of these observations, described in a paper published October 15 on arXiv.org, ...
(Phys.org) —In a dark, starless patch of intergalactic space, astronomers have discovered a never-before-seen cluster of hydrogen clouds strewn between two nearby galaxies, Andromeda (M31) and Triangulum (M33). The researchers ...
