galaxy : any of the very large groups of stars and associated matter that are found throughout the universe — Webster
Galaxy is a massive, gravitationally bound system that consists of stars and stellar remnants, an interstellar medium of gas and dust, and an important but poorly understood component tentatively dubbed dark matter. Galaxies contain varying amounts of star systems, star clusters and types of interstellar clouds. In between these objects is a sparse interstellar medium of gas, dust, and cosmic rays. Dark matter appears to account for around 90% of the mass of most galaxies. — Wikipedia

Virtual 'universe machine' sheds light on galaxy...
on August 9, 2019 at 9:08 pm
By creating millions of virtual universes and comparing them to observations of actual galaxies, researchers have made discoveries that present a powerful new approach for studying galaxy formation.

Gravitational wave researchers have developed a new model that could help astronomers track down the origin of heavy black hole systems in the Universe.
A long time ago, galaxies far, far away
on August 7, 2019 at 5:19 pm
Astronomers used the combined power of multiple astronomical observatories around the world and in space to discover a treasure-trove of previously unknown ancient massive galaxies. This is the first multiple discovery of its kind and such an abundance of this type of galaxy defies current models of the universe. These galaxies are also intimately connected with supermassive black holes and the distribution of dark matter.
ALMA dives into black hole's 'sphere of influence'

A second planet has been discovered circling Beta Pictoris, a fledgling star in our own galaxy offering astronomers a rare glimpse of a planetary system in the making, according to a study published Monday.
Scientists complete LSST's digital sensor array
on August 19, 2019 at 3:05 pm
After 16 years of dedicated planning and engineering, scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have completed a 3.2 gigapixel sensor array for the camera that will be used in the Large Synoptic Survey Telescope (LSST), a massive telescope that will observe the universe like never before.
Spotting merging galaxies
on August 19, 2019 at 12:25 pm
Over 30 years ago, the Infrared Astronomy Satellite discovered that the universe contained many extremely luminous galaxies, some more than a thousand times brighter than our own Milky Way, but which are practically invisible at optical wavelengths. These galaxies are powered by bursts of star formation buried deep within clouds of dust and gas. The dust absorbs the ultraviolet light while radiating at infrared wavelengths. In many cases the hyperactivity was triggered by a collisional […]

On an August morning in Paris, when most of the city is in an advanced state of summer torpor, hundreds of young men and women are sweating it out in the third week of a gruelling month-long endurance test.
Best of both worlds: Asteroids and massive mergers
on August 16, 2019 at 1:51 pm
The race is on. Since the construction of technology able to detect the ripples in space and time triggered by collisions from massive objects in the universe, astronomers around the world have been searching for the bursts of light that could accompany such collisions, which are thought to be the sources of rare heavy elements.
