Astronomers learned to see beyond the Milky Way's glare into a hidden realm of faint galaxies.
Compared to some other galaxies in our Universe, the Milky Way is a rather subtle character. In fact, there are galaxies that are a thousands times as luminous as the Milky Way, owing to the presence of warm gas in the galaxy's Central Molecular Zone (CMZ). Show More Summary
(Columbia University) An international team of astronomers has discovered that some stars located in the Galactic halo surrounding the Milky Way -- previously thought to be remnants of invading galaxies from the past -- are instead former residents of the Galactic disk, kicked out by those invading dwarf galaxies.
New findings by the Fermi gamma-ray space telescope raise hopes of detecting other new millisecond pulsars, e.g., from a predicted large population of such objects towards the center of our Galaxy. Scientists from the Max Planck Institute for Gravitational Physics...
A new study of stars in the Milky Way suggests how our Galaxy’s formation and evolution might have been affected by the tidal pull of other passing galaxies. Click the link Tidal forces kicked stars out of our Milky Way Galaxy to read more. Show More Summary
Maunakea, Hawaii - An international team of astronomers led by the Max Planck Institute for Astronomy (MPIA) has made a surprising discovery about the birthplace of groups of stars located in the halo of our Milky Way galaxy. These halo...Show More Summary

The halo stars of our galaxy seem not to be randomly distributed in the halo - instead many are grouped together in giant structures - immense streams and clouds (or overdensities) of stars, some entirely encircling the Milky Way. These...
Astronomers have investigated a small population of stars in the halo of the Milky Way Galaxy, finding its chemical composition to closely match that of the Galactic disk. This similarity provides compelling evidence that these stars have originated from within the disc, rather than from merged dwarf galaxies. Show More Summary
The NASA/ESA Hubble Space Telescope caught sight of a soft, diffuse-looking galaxy that is probably the aftermath of a long-ago galactic collision. Two spiral galaxies, each perhaps much like the Milky Way, swirled together for millions of years.
Galaxies have supermassive black holes at their centres - our Milky Way, for example, has its own four-million-solar-mass one, Sagittarius A. Some astronomers have previously thought that there's a simple relationship between the galaxy's...Show More Summary
Astronomers originally thought that Andromeda was two to three times the size of the Milky Way, but that's not the case.
But its weight class just got shrunk.
The supermassive black holes lurking at the center of galaxies have been known to chow down on anything unlucky enough to pass too close, but the opportunity to see that in action rarely occurs at the Milky Way's quiet core. Now, astronomers...Show More Summary
The Milky Way’s closest big neighbour, the Andromeda galaxy, is less than half as massive as had previously been thought, new research shows. Click the link Andromeda galaxy is cut down to size in astronomers’ new study to read more....Show More Summary
Five decades of common knowledge about the Milky Way and Andromeda galaxies has been turned on its head, with astronomers at the International Centre for Radio Astronomy Research (ICRAR) discovering that our nearest galactic neighbor,...Show More Summary
Australian Scientists studying at the International Centre for Radio Astronomy Research just found out something pretty cool - turns out the Andromeda galaxy, which is our Milky Way's closest neighbour, is around the same size. We used to think Adropmeda was up to three times larger than the Milky Way, and that one day it would engulf us entirely. Show More Summary

Astronomers have discovered that our nearest large neighbour, the Andromeda galaxy, is roughly the same size as the Milky Way. It had been thought that Andromeda was two to three times the size of the Milky Way, and that our own galaxy would ultimately be engulfed by our supposedly bigger neighbour. Show More Summary
The Milky Way's neighbouring galaxy, Andromeda, was formed in a colossal crash between two smaller star systems no more than three billion years ago when Earth already existed, researchers said Wednesday.
