Using the Very Large Array (VLA), astronomers have conducted observations of neutral gas in the galaxy JO206. Results of these observations provide important information regarding gas stripping and enhanced star formation ...
The center of our galaxy is a frenzy of activity. A behemoth black hole—4 million times as massive as the sun—blasts out energy as it chows down on interstellar detritus while neighboring stars burst to life and subsequently ...

Using microlensing technique, astronomers have found a new giant planet orbiting a brown dwarf located in the bulge of the Milky Way galaxy. The newly discovered exoplanet, designated OGLE-2017-BLG-1522Lb, is most likely ...
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 ...
Novel computational methods have helped create the most information-packed universe-scale simulation ever produced. The new tool provides fresh insights into how black holes influence the distribution of dark matter, how ...
