Jakarta – Astronomers have seen a dying Sun-like star swallowing planets orbiting it. Scientists say the possibility that this will also happen to the Sun and Earth.
Reported from detikINET, the cataclysmic event is located about 13,000 light years away. This event was observed using the Gemini South telescope in Chile.
Such a sight occurs when stars, similar to the Sun, are nearing the end of their lives. The dying star expands to 1,000 times its normal size and turns into a ‘red giant’.
Eventually, the dying stars swallowed up the inner planets of their Solar System.
This event is not the first time, but has occurred several times a year in the Milky Way Galaxy. However, but has never been seen directly through observation.
Until finally astronomers can witness the event. The star grows to about 100 times brighter in just 10 days before fading. Then there was a longer lasting cold signal arriving on Earth. It may be the last traces of a planet swallowed up by its star.
Published in the journal Nature, astronomers reveal how imaging technology on Gemini South and archived infrared data from NASA’s space telescope were used to identify the event, which has been dubbed ZTF SLRN-2020.
From Sky News, it is stated that the star is estimated to be between 0.8 and 1.5 times the mass of the Sun. While exoplanets that are swallowed are 1 to 10 times the mass of Jupiter.
Scientists say the same thing is likely to happen to our Solar System, where the Sun will eventually devour Earth in the same way, along with Mercury and Venus. But don’t worry, it’s estimated that this event will only happen in 5 billion years.
“We are looking at the future of the Earth. If there were other civilizations that observed us from a distance of 10,000 light years when the sun engulfed the earth, they would see the sun suddenly brighten when it released some material, then formed dust around it,” said Dr. Kishalay De from MIT.
