Hubble Telescope captures a Stellar Thief star stealing from a nearby supernova



Never assume that a star is too big to steal. If you let carefree hydrogen lying around, it will tear that down in its gravity.

In this particular case, the crime happened a long time ago, but astronomers have just solved the cold case with new evidence from nowhere on the Hubble Space Telescope. While investigating the remains of a star called NGC 7424, which had become supernova 17 years ago, the telescope saw something out of the ordinary: another star near the crime scene.

In order to break away from the silly crime metaphors, Hubble had picked up concrete evidence that a supernova had occurred in a binary system or binary star system – which scientists had predicted but never found proof of ̵

1; and that the presence of a second star probably played a role in this early supernova. According to new research on this incident, this companion star sucked hydrogen from NCG 7424 and gradually destabilized it.

Back to the metaphors of silly crime, that was not just theft – it was murder.

NGC 7424 had large amounts of hydrogen in its "stellar shell" Due to its proximity to NGC 7424, this companion star had absorbed the star's hydrogen millions of years before the supernova into its own gravity, making the supernova a supernova stripped envelope Although the supernova light reached Earth only 17 years ago and the star was 40 million light-years away in the Grus constellation (the crane), the first explosion was so bright It was only recently that the light had faded so much that Hubble discovered this second star, pointing to the supernova, which was the only one Represented half of a very bright binary sunset.

According to Stuart Ryder, principal author of the New Research of the Australian Astronomical Observatory (AAO) in Sydney, most of the big stars tend to be in binary systems, causing the famous tattooine sunset means of S tar Wars is hardly a unique view in the whole universe (assuming there are solid planets from which to see it).

So finding proof of this behavior is so refreshing, as Ryder says in a press release from Hubble's website:

  Opening Quote

"We know that the majority of massive stars in binary pairs consists of these binary ones Couples interact and transmit gas from one star to another when their orbits bring them close to each other. "

  Final Quote

The criminal star is likely to get away with it. But if you ever figure out how to get a big, distant star into a courtroom, then let NASA know.
