Something Big Came OUT Of A Black Hole Recently! Scientists Baffled 3/15/16
You don’t have to know a whole lot about science to know that black holes normally suck things in, not spew things out. But NASA detected something mighty bizarre at the supermassive black hole Markar...

"The Black Hole Paradox" --New Theory Says Soon After Big Bang, Black Holes Lit Up the Universe
Soon after the Big Bang, the universe went completely dark. The intense, seminal event that created the cosmos churned up so much hot, thick gas that light was completely trapped. Much later—perhaps a...
Gamma-Ray Blazars Powered By Billion-Solar-Mass Black Holes Found
Using the Fermi Gamma-ray Space Telescopes, astronomers found 5 early universe gamma-ray blazars. Two of them were powered by “billion-solar-mass” black hole...
Astronomers find a ‘nearly-naked’ supermassive black hole
A close galactic encounter gave these astronomers an interesting discovery
The case for black holes being nothing but holograms just got even stronger
If anything can sum up just how little we truly know about the Universe, it’s black holes. We can’t see them because not even light can escape their gravitational pull, we have no idea what they’re ma...
X-ray Echoes Map a Black Hole’s Disk
Some 3.9 billion years ago in the heart of a distant galaxy, the tidal pull of a monster black hole shredded a star that wandered too close. X-rays produced ...
Hubble Captures The Beating Heart Of The Crab Nebula
Peering deep into the core of the Crab Nebula, this close-up image reveals the beating heart of one of the most historic and intensively studied remnants of a supernova — an exploding star.
Ancient and Young Water Worlds of the Cosmos --"NASA Pinpoints Water Vapor Around a Newly Forming Star"
A team of scientists using the Stratospheric Observatory for Infrared Astronomy (SOFIA) has pinpointed the amount and location of water vapor around a newly forming star with groundbreaking precision.

Star formation
Star formation is the process by which dense regions within molecular clouds in interstellar space, sometimes referred to as "stellar nurseries" or "star-forming regions", collapse to form stars. As a...
