In images from the Hubble Space Telescope, scientists have spotted an entirely new phenomenon. Reaching tens of thousands of light-years into the void of space, vast shadows stretch from the centre of the galaxy IC 5063, as though something is blocking the bright light from therein.
You've probably seen something very like it before – bright beams from the Sun when it's just below the horizon and clouds or mountains only partially block its light, known as crepuscular rays . According to astronomers, the shadows from IC 5063 could be something very similar. They're just a whole lot bigger – at least 36,000 light-years in each direction.
Quite a lot has been going on:

Neutron stars consists of highly compressed dense matter. The mass of one and a half solar masses is squeezed to the size of just a few kilometers. This corresponds to similar or even higher densities than in the inner of atomic nuclei. If two neutron stars merge, the matter is additionally compressed during the collision. This brings the merger remnant on the brink to collapse into a black hole.

But under which conditions does a black hole actually form? This is the central question of a study lead by the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt within an international collaboration. Using computer simulations, the scientists focus on a particular process to form black holes namely the merging of two neutron stars (simulation movie).

The Black Hole: Go Inside Las Vegas Raiders Football - Sports Illustrated Oakland Raiders News,
Henderson, Nev. -- People are hungry for information on their beloved Las Vegas Raiders, and I am here with a smorgasbord of food.
I get a lot of nuggets and information that alone are not big enough for a story. When I have a few that I can assemble, I will, and when I only have one or two, I will post them on our community page. So, welcome to The Black Hole.

I have so many more notes, and I promise that I will get them all in. Our "Black Hole" articles will happen once a week.
Hubble Glimpses Huge "Dark Rays" Streaming Out of Black Hole
Scientists took a closer look at Hubble images of a supermassive black hole and saw what appeared to be long beams of darkness streaming out.
Citizen scientist Judy Schmidt first noticed the strange phenomenon in Hubble images last year — and it was her tweets asking what was going on that spurred the Harvard research in the first place.
"I noticed the dark rays almost immediately after I'd opened the file in Photoshop and began working to enhance them to make sure what I thought I saw was there," Schmidt said in a Harvard press release .

All this is to say that the subject of the watch was one of the great scientists of our age (to say nothing of a pop culture icon; he played himself both on The Simpsons and Star Trek: The Next Generation ) and that the commercial effort goes hand in hand with support of very worthwhile causes both medical and cosmological.
Hubble captured shadow play of disk around a black hole - Tech Explorist
Black holes are the universe's monsters: voracious eating machines that swallow anything that ventures near them.
Black holes pull stars and gas into its disk that swirls around. This event produces immense energy as well as a powerful gusher of light from superheated infalling gas.
The swirling disks are so distant that it is incredibly challenging to get any detail about them. Luckily, by a quirk of alignment, astronomers may be getting a glimpse of the disk’s structure around the black hole in nearby galaxy IC 5063.
