Huge, unusually powerful supernova explosion in space discovered by scientists

Huge, unusually powerful supernova explosion in space discovered by scientists

In space things common walk boom.

And recently, on September 10th, astronomers observed an extraordinarily colossal boom. NASA’s Swift Observatory, designed specifically to detect the most powerful explosions in the universe known today – called gamma-ray bursts – has detected one extremely powerful such burst. Something tremendously powerful must be creating these energy beams that are pouring through placeand scientists say they are caused by the collapse and explosion of giant stars, called events supernovae.

For a star to go supernova, it has to be fairly massive – at least eight times the size of that Sun. But for a supernova to produce the strongest type of gamma-ray burst, the star has to be about 30 to 40 times the size of the sun. This powerful new discovery, so rare we’ll likely only see something of this magnitude about once every decade, comes from such a powerful star.

“It’s a very unique event,” said Yvette Cendes, astronomer and postdoctoral researcher at the Harvard-Smithsonian Center for Astrophysicssaid Mashable.

The important thing is that you don’t have to worry. This terrible explosion occurred in a galaxy 2 billion light years away. At such a distance, its energy, which has been traveling and spreading through space for eons, poses no threat to us. But we can easily spot it using satellites.

“It’s like getting a front row seat to a fireworks display,” Cendes explained.

(Gamma rays are in the same radiation spectrum as AM and FM radio, visible light you can see, and X-rays, although gamma rays have the most energy.)

“It’s incredible, incredibly rare.”

Astronomers have never seen a gamma-ray burst in our galactic neighborhood (meaning the local galaxies around us). That’s because starbursts themselves aren’t all that common. A star in our Milky Way becomes supernova about once a century. But a giant star, the type needed to produce an extremely bright and long (on the order of several minutes) gamma-ray burst, only explodes in a medium-sized galaxy like ours about once every million years, Cendes noted.

“It’s incredibly, incredibly rare,” Cendes said.

Gamma-ray bursts are detected far away because they are there Hundreds of billions of galaxies out in the deep cosmos full of stars. There are relatively few opportunities for such an event near us compared to the wider universe. (You also need to be looking in the direction of the “funnel” of energy radiated into space from the blast to see it.)

Because these gamma-ray bursts often occur billions of light-years away, the instruments built to detect these signals are extremely sensitive. This is another reason why this detection, which was relatively “close”, was so intense and “bright”.

“It’s like pointing a telescope at the sun,” Cendes explained. “It saturated the detectors.” The explosion ‘among the most luminous events known’ determined by NASA.

You may be wondering what happens to the exploded star now after such a dramatic collapse and explosion. It probably turned into a black hole. “Most black holes are formed from the remains of a large star that dies in a supernova explosion,” Notebook NASA.

Black holes are incredibly strange cosmic objects. As Mashable previously reported, Black holes are places where matter has been compressed into an extremely compact area. If the Earth were (hypothetically) crushed into a black hole, it would be less than an inch in diameter. However, the object would still be extremely massive, containing all of the mass of our planet. This creates a place with such a strong pull that not even light can escape. (Things with more mass have a stronger gravitational pull.)

Astronomers like Cendes are now observe the aftermath of the dramatic gamma-ray burst with powerful telescopes such as the Submillimeter Array radio telescope on Mauna Kea in Hawaii.

So the universe keeps rolling. A star dies. A black hole is born. And intelligent life, about 2 billion light-years away, sees what’s happening.
