A runaway star travelling across our galaxy at enormous speed was probably hurled from its cluster by a previously unknown type of black hole.
Researchers from the Keck telescope believe that the high-velocity star, PG 1610+062, was flung across the Milky Way by a “mid-mass black hole” (MMBH).

Hey, some good news: The impending colossal cosmic train wreck of the Andromeda galaxy smashing into our Milky Way and causing massive havoc and chaos on a literally galactic scale has been postponed. According to new measurements and calculations it’ll happen 4.6 billion years from now, not 3.9 billion.

A team of astronomers has produced a 3D map of our galaxy, the 1st accurate one, they say. It reveals our galaxy’s true shape as warped and twisted.
We think of spiral galaxies as being flat. You often hear the disk of our galaxy described as “flat as a pancake.” The large spiral galaxy next door – the Andromeda galaxy – looks flat through a telescope. But nature can be intricate, and, this week (February 4, 2019), astronomers made a surprising announcement. They said our home galaxy, the Milky Way, isn’t flat. Instead it’s warped and twisted.

In past, we can only see the sun, the moon, and stars. The advancements in science took place and made people able to see and study the solar system. Further developments made scientists able to study the Milky Way Galaxy. Science is getting advance with time and is finding its way in space step by step. Space is full of different wonders. At present, scientists have found one such wonder named as Whirlpool Galaxy.

The end of the Milky Way as we know it may come a few billion years ahead of schedule.
According to a new paper published Jan. 4 in the journal Monthly Notices of the Royal Astronomical Society, our home galaxy appears to be on a crash course with one of its nearest satellites, the spiral of stars known as the Large Magellanic Cloud (LMC).

Looking out at the Universe today, it’s easy to be absolutely awed by all that we can find. The stars in our night sky are just a tiny fraction — a few thousand out of hundreds of billions — of what’s present in our Milky Way. The Milky Way itself is just one lonesome galaxy out of trillions present within the observable Universe, which extends in all directions for some 46 billion light-years.

If you are into stargazing and astronomy, in general, then you probably know that the Milky Way, i.e., the galaxy of which we are a part, is constantly moving. Our planet, the sun, the solar system and our entire galaxy is constantly revolving. More specifically, the arms of the galaxy are moving through space, so the sun and our solar system travel with them.

The universe is so unfathomably huge that our tiny human brains can barely imagine just how big it really is out there. Case in point, a paper recently published in the Astrophysics Journal estimates that the mass of the Milky Way galaxy is 9.5 x 10^41 kilograms — 4.8 x 10^11 times the mass of the sun. That sounds wild, but can those impossibly gigantic numbers mean anything to us? Continue reading The Milky Way is 392 decillion times more massive than the heaviest thing we’ve ever weighed

We’re fleeing from a mysterious ‘dead zone’
You can’t feel it, but our planet is orbiting the Sun at speeds of roughly 100,000 km/h (62,000 mph), and something is making our Milky Way galaxy move through the Universe at more than 2 million km/h (1.2 million mph). That’s 630 km per second, and now scientists might have finally figured out why. Continue reading An unexplained ‘void’ appears to be pushing the Milky Way through the Universe at 2 million km/h

It was hiding behind the Milky Way.
Through the thick fog of our own galaxy, astronomers have spotted an ultimate prize: one of the largest-known structures in the Universe.
Called the Vela super-cluster, the newly discovered object is a massive group of several galaxy clusters, each one containing hundreds or thousands of galaxies. Continue reading Astronomers have discovered one of the most massive objects in the universe
