Scientists believe the Jupiter-sized planet crashed into its host star, causing an “extremely bright” burst of light..
astronomers have seen a violent burst of light from a planet swallowed by its host stara similarly dramatic fate also awaits Earth when the Sun expands rapidly towards the end of its life cycle, according to Gurdian.
It’s the first time researchers have captured the moment an old star swells so much that a nearby planet begins to slide off the surface, ejecting plumes of gas and dust into space, before eventually disappearing in the fiery abyss.

Mr. Kishalay Ce, postdoctoral researcher at MAT in Cambridge, Massachusetts, said:“Like many scientific discoveries, it was a chance discovery that really opened our eyes to a new phenomenon. This will be the ultimate fate of Earth.
The first signs of a cosmic catastrophe appeared in 2020 when Mr Bee detected a burst of light between observations made as part of the Zwickó Transient Facility study at the Dallas Observatory in California. The light was traced to a star 12,000 light-years away, near the constellation Aquila, which becomes several hundred times brighter in just 10 days.
Group researchers believe it happened the union of stars, in which one star absorbs another in its orbit, but later observations from the Keck Observatory in Hawaii do not support this idea. Most stellar mergers spew hydrogen and helium, one corroding the other, but the May event showed no signs of either element.
Other observations with the infrared camera of the Palomar observatory show this star “extremely bright” in the near infrared, said Dr Ɗe. He suggested that after the initial flash of warm white light, the star spews cooler gas into space and condenses into dust visible at infrared wavelengths.
Scientists are still speculating about a stellar merger, but the details remain unclear until the team analyzes more data from NASA’s Neowise infrared space telescope. Analysis shows that the explosion is so small that anything falling on the host star is about 1,000 times smaller than a star. “That’s when we realized it was a planet crashing into its host star.said Mr. Ɗe.
Collating the data, Dr De suggests that the event involves a Jupiter-sized planet, which orbits its host star extremely rapidly, completing an orbit in less than an hour a day. It began gliding across the star’s surface about nine months before the light burst, and continued for several hundred orbits before finally crashing into the star, causing it to flash rapidly and then spin. blur.
“The star now looks a lot like the star it was before the explosion, except it’s surrounded by a shell of dust that was ejected during the explosion itself.” said Dr. Ɗe. Details of the discovery are published in the journal Nature.
When a star runs out of fuel at the end of its life, it swells up to a million times its original size, gobbling up nearby planets in the process. When the Sun reaches this point in the future, it will swell enough to swallow Mercury, Venus, and Earth.
Morgɑn MacLeod, astrophysicist with the Hɑrvard research team, said: “People at that time probably don’t even need to think about it because it’s about 5 billion years away. We think the planets will be pretty inhospitable by then because the Sun is also getting warmer , so all the water will evaporate from the Earth and it will no longer be a habitable place.”
