The new study will help better understand the origin of some of the heaviest elements in our universe.
Astronomers using a telescope at the Inter-American Observatory of Cerro Tololo, Chile, have discovered for the first time a binary star system that, when it explodes, produces gold, platinum and uranium. Space writes about it.
It is noted that this is a very rare phenomenon, because when stars explode, their entire outer shell flies into space, and the core shrinks to a minimum size, forming a neutron star.
In rare cases, the eruption is not very strong. This is what happened to the neutron star SGR 0755-2933. It, along with the ordinary star CPD-29 2176, is located at a distance of 11,400 light-years from Earth.
“The fact is that the star SGR 0755-2933 became a neutron star as a result of a “quiet” supernova explosion about 1 million years ago, but after another 1 million years its companion will become a neutron star in the same way. After which both stars will approach each other and they will collide. As a result, there will be a powerful explosion – a kilonova,” said astronomers.
According to them, the explosion of kilonova leads to the appearance of platinum, uranium and gold in space. These elements fly very quickly through space and end up in the interstellar medium. And then they hit the asteroids.
Earlier, NASA’s Juno spacecraft sent back stunning new images of the gas giant Jupiter. They, most likely, may be the last, because technical problems have been identified with the device.
