The unpublished video of the explosion of a star 1,200 million light-years – Ecuavisa

“To see something that happens in a matter of minutes, as a clash of rupture, you have to have a camera monitoring the constantly sky,” said the professor of astrophysics at the University of Notre Dame Peter Garnavich, in a statement NASA.

“I do not know when a supernova will occur, and Kepler allowed us to witness from the beginning.”

Garnavich was who led the study that Thursday is published in the journal Nature.

the shock wave lasted less than an hour, so to “hunt” this time, the team had to analyze the light for more than two years every 30 minutes picked Kepler.

And the effort paid off.

in 2011, two massive stars, called red supergiant, exploded in the sights of Kepler.

space telescope captured the light that occurred when the star exploded.

first, the KSN 2011a, is nearly 300 times the size of our sun and is at a distance of 700 million light years .

and second, KSN 2011d, is about 500 times larger than our star and is located 1,200 million light years.

“to put these sizes in perspective, Earth’s orbit around the sun would fit comfortably within these colossal stars, “said Garnavich.

When a star of this size is aging and its energy is exhausted, gravity causes it to collapse.

While the two explosions released a similar power, no one could see a clash of breaking into the smaller star.

a mystery

Scientists believe this could be because it was surrounded by a gas that hid the wave when the shock break came to the surface of the star.

the study of supernovae help understand the origin of life .

“This is the mystery of the results,” said Garnavich. “You look at two supernovas and see two different things, that is maximum diversity”..

The study of supernovae is important because all the heavy elements in the universe come from them

“By example, all silver, nickel and copper on Earth, even in our bodies comes from the explosion of dying stars, “said Steve Howell, another NASA scientist.

” life exists because supernovae, “he said.

the research team Studio Extragalactic Kepler is finishing desgranar data of the first mission of the telescope.

the Kepler now entered a second phase, with known as K2.

the team expects mission to hunt more events supernovas in distant galaxies even more.
