NASA Telescopes Capture Birth of Black Hole or Neutron Star

Postado Janeiro 11, 2019

This celestial detonation was an "unprecedentedly bright and rapidly evolving stellar explosion" the likes of which had never been seen before, so much so, that teams across the globe immediately pointed their telescopes at this "space engine" located in a galaxy 200 million light years away.

Don't have a cow, man.

NASA's Asteroid Terrestrial-impact Last Alert System telescope in Hawaii picked up a brief and unusual burst in the night sky on June 16, 2018, the USA space agency said in a statement. With the first observations of the formation of a black hole or neutron star in hand, astronomers will be able to better understand what happens in the moments that a star dies, and a odd new object springs into being.

Astronomers may have spotted the birth of either a black hole or a neutron star after investigating a mysteriously bright flash in the night sky. The bright glow was caused by the debris swirling around its event horizon, astonishing the researchers.

Using data from multiple NASA missions, including the Neil Gehrels Swift Observatory and the Nuclear Spectroscopic Telescope Array (NuSTAR), a team of scientists speculate that the Cow is a monster black hole shredding a passing star.

Other researchers involved in the work support the notion of the formation of a black hole or a neutron star.

Margutti noted that science has known from theory that when a star dies it forms either a black hole or neutron star, but neither had ever been observed right after they are born.

The relatively clean makeup helped astronomers, Margutti added.

"A "lightbulb" was sitting deep inside the ejecta of the explosion", Margutti said.

The findings were presented at the American Astronomical Society on Thursday and the research will eventually be published in the Astrophysical Journal.

The Cow was up to 100 times too bright to be a supernova, said Dr Margutti, and disappeared too quickly too.

"In a universe where some phenomena last for millions and billions of years, two weeks amounts to the blink of an eye", the statement said. "That was enough to get everybody excited because it was so unusual and, by astronomical standards, it was very close by".
