Cold gas ejected from the center of the Milky Way puzzles scientists

Science

Aug. 19 (UPI) -- Astrophysicists have found bullet-like globs of dense, cold gas that were expelled from the center of the Milky Way. Researchers described the strange gas in a new paper, published Wednesday in the journal Nature, but the cause of their ejection remains a mystery. Advertisement Solving the mystery, authors of the new study contend, could help cosmologists better understand the evolution of galaxies like the Milky Way. Scientists have previously spotted gas being shot from the center of faraway galaxies, but never inside the Milky Way. "Our own galaxy is almost like a laboratory that we can actually get into and try to understand how things work by looking at them up close," lead study author Enrico Di Teodoro, astrophysicist at Johns Hopkins University, said in a news re...

‘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. Image: Our sun is one of many stars which make up the Milky Way According to Australian and American researchers, the explosion was too huge to have b...

Milky Way’s centre exploded 3.5 million years ago

Science

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...
