Astronomers have seen the primary proof of a dying sun-like star engulfing an exoplanet in what may very well be a preview of Earth's final destiny.

The cataclysmic occasion, some 13,000 gentle years away, was noticed utilizing the Gemini South telescope in Chile.

Such spectacles happen when stars just like our solar close to the top of their life.

Dying stars develop to upwards of 1,000 occasions their regular dimension and rework right into a so-called "red giant".

Eventually, they engulf their photo voltaic system's inside planets.

This occurs a couple of occasions a 12 months throughout the Milky Way however had by no means been seen occurring dwell till now.

Writing within the journal Nature, astronomers revealed how imaging know-how on Gemini South and archival infrared information from a NASA area telescope was used to determine the occasion, dubbed ZTF SLRN-2020.

The star is estimated to have been between 0.8 and 1.5 occasions the mass of our solar, whereas the engulfed exoplanet - which is the title given to planets outdoors our photo voltaic system - was one to 10 occasions the mass of Jupiter.

The possible destiny of Earth

The outburst of parts and materials from the engulfment lasted roughly 100 days.

Study co-author Ryan Lau stated: "That's more star and planet-forming material being recycled, or burped out, into the interstellar medium thanks to the star eating the planet."

It is probably going that our solar will finally find yourself devouring the Earth in the identical approach, together with Mercury and Venus - although fortunately not for about 5 billion years.

Mr Lau added: "After the billions of years that span the lifetime of our solar system, our own end stages will likely conclude in a final flash that lasts only a few months."

Now that astronomers have seen one in every of these planetary engulfments occurring in actual time, they hope to have extra success discovering them elsewhere within the cosmos.

Their work might be helped by the under-construction Vera C Rubin Observatory, additionally in Chile, which is able to conduct an unprecedented decade-long survey of the sky when it comes on-line in 2025.
