A sausage-shaped galaxy smashed into our own Milky Way billions of years ago, changing our galaxy’s shape forever.
The European Space Agency’s Gaia satellite has produced remarkable data, which was analyzed by an international team of astronomers. This data suggested that our galaxy, the Milky Way, collided with a smaller galaxy called Gaia Sausage about 9 billion years ago. Scientist suspect that this crash shaped the Milky Way’s current form and added to its supermassive black hole. Our supermassive black hole swallowed the smaller black hole in a spiral dance of death for the Gaia Sausage.

Vasily Belokurov is the lead author and a researcher at the University of Cambridge in the UK, and he also is a researcher at the Center for Computational Astrophysics at the Flatiron Institute in New York City. His statement in the press release points out that after the collision, the stars left behind from the Sausage galaxy moved in radial orbits in long, narrow patterns; the Sausage galaxy gets its name from this sausage-shaped, radial orbit.

Dr. Levin was born and grew up in Vermont with many winters spent in Florida as a child. As a teenager he wrote poetry, served as a lifeguard and played football. He currently enjoys sailing, exploring underwater caves, snorkeling, writing science fiction and other pursuits. After working on the Apollo and Mars projects, he returned to school to study under Nobel Laureate Paul Dirac, obtaining his PhD in 2.5 years. Dr. Levin founded two companies and served the science policy apparatus in President Ford’s administration. He has been published over 44 times in scientific literature and was awarded over 32 US patents. The science fiction writer is now emerging with his first work, a trilogy entitled 30th Century. The first award-winning book, 30th Century: Escape, is currently available on Amazon. Book two in the series, 30th Century: Revived, should be released before the end of April 2018.
