“Milky Way’s Hidden Past” –Gaia Unveils Dark-Matter Object 1-100 Million Times Mass of the Sun

Milky Way Dark Matter Signal

 

Since the Gaia Spacecraft’s April 2018 data release, astronomers have unveiled a Milky Way teeming with astounding surprises, including hints of dark-matter clumps that might eventually provide a better grasp of the elusive material’s properties. These early, easy-to-spot findings, reports Adam Mann in Nature, have been “transformational.” Astronomer Vasily Belokurov at the University of Cambridge, UK, said they are merely a glimpse of what is to come: “How we see the Milky Way has clearly changed.”

“We still don’t know what this is, although it is one of the most intensely studied cosmic events in history,” says Caltech’s Anna Ho, lead author of a new study about the event. Cow was likely a supernova, she says, although some scientists have proposed that it instead may have been caused by a black hole ripping apart a type of star called a white dwarf.

“Four Suns in the Sky” –Planets of Strange Two-Star Systems

Kepler Star System 35a and b

 

“We used to think other solar systems would form just like ours, with the planets all orbiting in the same direction around a single sun,” said Daniel Price of Monash University’s Center for Astrophysics (MoCA). “But with the new images we see a swirling disc of gas and dust orbiting around two stars. It was quite surprising to also find that that disc orbits at right angles to the orbit of the two stars. Incredibly, two more stars were seen orbiting that disc. So if planets were born here there would be four suns in the sky!”
