black holes

How many black holes does it take to fill a galaxy? Apparently a lot more than we thought.

See the "stars" in the picture above. Well, those aren't stars. They're supermassive black holes. Black holes don't generate much radiation and thus, are difficult for astronomers to spot. However, as they devour everything around it, materials spiral into the black hole like water spinning around a drain. This action generates radio waves which scientist can use to detect the presence of a black hole. The detailed map of black holes was created by astronomers using the low radio frequency signatures detected by the LOw Frequency ARray (LOFAR) in Europe. The LOFAR array consists of about 20,000 radio antennas distributed across 52 different locations in Europe. Scientists wrote a special program that uses the LOFAR radio telescope data to map out the black holes we see in the

For the first time, scientists have captured a picture of a black hole in space and it’s amazing!

Astronomers have done what was thought to be impossible – they captured the unseeable, a picture of a black hole, an object so dense, nothing, not even light, can escape it. The photo was taken by scientists at the Harvard-Smithsonian Center for Astrophysics. The picture of the black hole shows a lopsided ring of light surrounding a dark circle – the black hole itself. The black hole is in a galaxy known as Messier 87 in the constellation Virgo. The black hole is 55 million light years away from earth. That is so far, if you hopped a ride on the Space Shuttle, it would take you 20,450,000 years to reach it. Here's what messier 87 looks like through a telescope. To capture the image was no

Scientists discover black hole that is 12 billion times larger than the Sun

Researchers in China have discovered a massive black hole that is 12 billion times the size of the sun. 12 billion times as big as our gigantic Sun! For reference, a billion is a thousand millions or 1 with nine zeroes after it. If you counted every second of your life, you’d only live a bit longer than 2 billion SECONDS. A billion pennies stacked on top of each other would reach 870 miles into the sky. The black hole they found is larger than any of its age ever found. A black hole is a dense region of space that has collapsed in on itself in a way that nothing can escape – not even light. This one was given the typical goofy astronomer name
