Not long ago, the center of the Milky Way exploded

An artist's impression of the massive bursts of ionizing radiation exploding from the center of the Milky Way and impacting the Magellanic Stream.

A titanic, expanding beam of energy sprang from close to the supermassive black hole in the centre of the Milky Way just 3.5 million years ago, sending a cone-shaped burst of radiation through both poles of the Galaxy and out into deep space.That's the finding arising from research conducted by

Will Andromeda start consuming the Milky Way?

Andromeda: our nearest large galactic neighbour.

Scientists have now charted the cannibalistic past of the neighboring galaxy to our own - Andromeda. The large galaxy now appears to have sights set on the Milky Way as its next main target.By pulling together big data, astronomers have figured out that Andromeda has, over time, consumed several smaller

Hypervelocity alien stars could be invading the Milky Way

Gaia mapping the stars of the Milky Way

Astronomers have discovered a population of incredibly fast-moving stars bearing down on the Milky Way. It is possible that these newly found "hypervelocity" stellar bodies were created in another galaxy, before being hurled out into intergalactic space on a collision course with the Milky Way.Our galaxy is populated by over

Four newly discovered Milky Way neighbors

Four newly discovered Milky Way neighbors

Ultra-faint dwarf galaxies are the smallest, most dark matter dominated, and least chemically enriched stellar systems in the universe, and are important targets for understanding dark matter and galaxy formation. They comprise by number the majority of galaxies in the universe, and not least, dwarf galaxies around the Milky Way

An ‘Invisible Galaxy’ May Be Hiding in the Milky Way

Milky Way

Scientists think that at the heart of nearly every galaxy, including our own Milky Way, lies a supermassive black hole (SMBH) with immense gravity. These SMBHs are surrounded by dense clusters of millions of stars and—according to findings published earlier this year—probably thousands of smaller, star-sized black holes that all orbit within a few

Magnetized inflow accreting to center of Milky Way galaxy

Milky Way

Are magnetic fields an important guiding force for gas accreting to a supermassive black hole (SMBH) like the one that our Milky Way galaxy hosts? The role of magnetic fields in gas accretion is little understood, and trying to observe it has been challenging to astronomers. Researchers at the Academia

Andromeda and Milky Way Galaxies Are Already Touching

Andromeda Collides Milky Way

The merger of the Milky Way and Andromeda galaxy won’t happen for another 4 billion years, but the recent discovery of a massive halo of hot gas around Andromeda may mean our galaxies are already touching. The Andromeda Galaxy is the largest member of a ragtag collection of some 54 galaxies, including the Milky
