Scientists have discovered the most powerful explosion ever seen in the universe, and it's a record brightness explosion! So where did this explosion take place? How far away is it?
We know that explosions in the universe are not like the explosions around us. Some cosmic explosions are so far away that we don't see them until billions of years after they happened! We know that about 13.7 billion years ago, the universe began to expand endlessly, with countless cosmic explosions occurring over those billions of years, but what caused these powerful cosmic explosions? The most powerful cosmic explosions known to science are called gamma-ray bursts, or space death, because they're so powerful!39bet-kết quả bóng đá-kết quả xổ số miền bắc-kèo bóng đá -soi cầu bóng đá-đặt cược
It's no exaggeration to say that a galaxy probably releases less energy in a year than a Big Bang event does in a few seconds, because this process can release as much energy as a star the size of our sun does in its entire lifetime. These intense flashes happen all the time, but it's comforting to know that they usually occur in galaxies billions of light years from Earth, shielding us from intense particle jets. However, because we don't get any warning of these explosions, and because these massive explosions usually last only a few seconds, it's difficult for scientists to observe them.
One of the largest cosmic eruptions scientists have seen so far, whose light has been spreading through the universe for nearly a century, was produced by a stellar behemoth that exploded shortly after the age of the first stars, the most energetic event known. It's 2.5 million times brighter than the brightest supernova. The gamma-ray burst is estimated to have occurred about 13 billion light years away, when the universe was only 630 million years old, and most likely came from the explosion of a massive star that, of course, has now become a massive black hole.
Not only that, NASA's swift satellite also detected a 10-second long gamma-ray burst, burst of afterglow red shift is so far the measured highest redshift. This means that the long journey to reach us before the swift satellite, is already very long wavelength achieved record found that including the gamma-ray burst was detected in 2008. However, this explosion came from an exploding star just 12.8 billion light years away.
In 2005, when astronomers using NASA's chandra X-ray observatory found the universe's most powerful eruptions of eruption is behind a supermassive black hole, eruption rate of shot in the chandra a called ms - 0735 clusters of hot gas of x ray image, we can see the huge eruption speed is very fast. The giant void is extending outward from the supermassive black hole at the center of the cluster.
The eruption, which lasted 100 million years and is still going on, produced millions of gamma-ray bursts in a cavity of energy equivalent to hundreds of years. Radio emissions show that jets of gas from the black hole are being pushed away from the hole at supersonic speeds at a distance of about a million light-years, about a trillion solar masses more massive than all the stars in the Milky Way.
