‘Strange objects’ found near Milky Way black hole

Technology
Scientists have been amazed by "strange objects" discovered near the supermassive black hole at the centre of the Milky Way.Astronomers from UCLA's Galactic Centre Orbits Initiative described the weird objects in a paper published in the academic journal Nature. "These objects look like gas and behave like stars," said the paper's co-author Professor Andrea Ghez. Star orbiting black hole backs Einstein's theory A...

Centre of the Milky Way ‘recently’ exploded

Technology
The black hole at the centre of the Milky Way recently exploded according to new research, shooting expanding beams of energy into deep space like a nuclear lighthouse,New research has discovered that the event, known as a Seyfert flare, created two cones of ionising radiation which sliced through the galaxy and even impacted cosmic bodies outside of it. Occurring just 3.5 million years ago - practically last week on a cosmic scale - the flare was so powerful that it hit the Magellanic Stream, a trail of gas extending between the Large and Small Magellanic Clouds, nearby dwarf galaxies.

Milky Way’s centre exploded 3.5 million years ago

A cataclysmic energy flare ripped through our galaxy, the Milky Way, about 3.5 million years ago, a team of astronomers say.They say the so-called Sifter flare started near the super massive black hole in the centre of the galaxy.The impact was felt 200,000 light-years away.The discovery that the Milky Way's centre was more dynamic than previously thought can lead to a complete reinterpretation of its evolution.Milky Way galaxy is warped and twisted, not flat"These results dramatically change our understanding of the Milky Way," says co-author Magma Guglielmo from the University of Sydney."We always thought about our Galaxy as an inactive galaxy, with a not so bright centre," she added. The flare created two enormous "ionisation ...

Milky Way galaxy is warped and twisted, not flat

Science
Our galaxy, the Milky Way, is "warped and twisted" and not flat as previously thought, new research shows.Analysis of the brightest stars in the galaxy shows that they do not lie on a flat plane as shown in academic texts and popular science books.Astronomers from Warsaw University speculate that it might have been bent out of shape by past interactions with nearby galaxies.The new three dimensional map has been published in the journal Science.The popular picture of the Milky way as the flat disc is based on the observation of 2.5 million stars out of a possible 2.5 billion. The artists' impressions are therefore rough approximations of the truer shape of our galaxy, according to Dr Dorota Skowron of Warsaw University."The inter...

Astronomers use Gaia data to model Milky Way-Andromeda collision

Science
Feb. 8 (UPI) -- Scientists have long suspected that the Milky Way and Andromeda galaxies are on a collision course, but now, thanks to new data from the European Space Agency's Gaia satellite, researchers finally know how fast and at what angles the two galactic bodies are approaching impact. The Milky Way and Andromeda, along with the smaller Triangulum, are the three biggest galaxies in the Local Group, a collection of more than 54 galaxies -- most of them dwarf galaxies. While scientists think all 54 members are organized by their gravitational influence on one another, the positioning and trajectories of Local Group members isn't well understood. "We needed to explore the galaxies' motions in 3D to uncover how they have grown and evolved, and what creates and influences their features...
