Scientists witnessed a real-life death star devouring a planet in its maiden discovery
Astronomers have found a new discovery and witnessed a sun-like star devouring a planet, revealing the future that will befall Earth in about 4 billion years when our elder sun swells to engulf our world, as per the new study.
After reading and analyzing the numbers of stars in all the stages of their evolution, astronomers reached the discovery that just as our sun and stars like it near the ends of their lives, they start exhausting their primary sources of energy, the Hydrogen near their cores. This activity leads their cores to contract and their external shells to expand and cool. In this “red giant” phase these stars may billow out anywhere from 100 to 1,000 times their original double radius, swallowing closely orbiting planets.
An Astrophysics at the Massachusetts Institute of Technology told in the interview “We know that this must happen to all planets that are orbiting at a distance smaller than that of the earth, but it was considered extremely challenging to provide experimental evidence for this,” says the study lead author Kishalay De.
He further explained that scientists have been seeing the process just before and shortly after the act of consuming planets. However, researchers had never captured a star in the act until now.
“Honestly, one of the biggest surprises for me was that we found it in the first place,’ also said in a mail “Planetary engulfment has been a fundamental prediction in our understanding of stars and planets, but their frequency has been very uncertain. So finding a potentially rare event for the first time is always exciting.”
De and his colleagues paid attention to the subject in 2020 when they examined a burst of radiation dubbed ZF SLRN-2020 in the Milky Way’s disc which is about 12,000 lights years away, somewhere in the Aquila. During his time a star brightened by a factor of 100 over the course of a week.

De says “The work started back in 2023 when I was not looking for this type of event actually,” also added, “I was looking for a much more common type of outburst called novae.” Generally, novae are the stellar explosion that can happen when a red giant purs fuel onto an associated white dwarf star.
This discovery was firstly by analyzing the data collected by the Zwicky Transient facility, which used to function at the California Institute of Technology’s Palomar Observatory. The Zwicky Transient Facility scans the star that rapidly turns bright, which could be events such as novas.
