Astronomers have spotted a bright flash of light from a Jupiter-size world being consumed by its own star in a preview of Earth’s likely fate.
Astronomers have spotted a star devouring one of its planets for the first time. It is a stunning preview of our own planet's fate, when, in roughly 5 billion years time, Earth too will likely be engulfed by our rapidly expanding sun.
By studying the light from the outburst, as well as the chemical signatures from the material burped out by the planet-devouring star, the scientists identified the consumed planet as a gas giant at least 30 times the size of Earth. Details of the first-of-its-kind observation were published May 3 in the journal Nature .
The astronomers first spotted the strange light burst using the Zwicky Transient Facility, an astronomical survey that scans the sky for sudden changes in star brightness using the California Institute of Technology's Palomar Observatory. It was then that they discovered the flash, designated ZTF SLRN-2020, which began as a brilliant beam of light and intensified 100-fold over the next 10 days. The light shone for 100 days before it sputtered out.
By using NASA's NEOWISE infrared space telescope, the researchers found the final clue to the mystery — the energy released by the flash was tiny, roughly 1,000 times less bright than any previous stellar merger. The astronomers realized they had caught the final moments of a Jupiter-size planet being engulfed by its star, burning incandescently as it fell to the red giant's core before being reduced to dust.
