By First time in historya group of scientists from different US universities achieved observe the precise moment in which a dying star completely swallowed a planetsomething that the Earth will suffer in approximately 5,000 million yearsaccording to research that has just been published in the Nature magazine.
It is that, until now, astronomers they had only been able to see the planets before or after being literally devoured by a starbut never at the very moment of the event, as it just happened.
According to the scientists, the unprecedented event took place in the vicinity of the constellation of the Eaglelocated more than 13,000 light years from our planetwhen the dying star exploded, causing his brightness and density multiplied by 100, in just 10 days of our planet Earth, which made it vanish very quickly.
Curiously, this spectacular and gigantic flash of white light was followed by a colder, longer-term signal than usualwhich led scientists to affirm that this combination could only be due to a wonderful event: a star engulfing a nearby planet.
The initial signal appeared in a search for data taken by the Zwicky Transient Facility (ZTF)which works on the Caltech’s Palomar Observatory in California and that it is an observatory that scan the sky for stars that change rapidly in brightnesswhose pattern could indicate the presence of supernovaegamma-ray bursts and other stellar phenomena.
“We were looking at the final phase of the engulfment and the future of the Earth.”, stated, in a press release, Kishalay Depostdoctoral researcher at Kavli Institute for Astrophysics and Space Research at the Massachusetts Institute of Technology,
“If some other civilization were watching us from 10,000 light-years away as the sun engulfed the Earth, they would see the sun suddenly shine as it ejected some material.then forms dust around it, before returning to what it was,” concluded the lead author of the research.
