NASA's Hubble Space Telescope has discovered a space crime, Outer Places . The telescope caught a glimpse of a "stellar thief," a star that had sucked hydrogen from a nearby supernova, possibly leading to the extinction of his neighbor.
NASA provides the entire backstory in a recent press release explaining that the supernova, called SN 2001ig, was sighted for the first time 17 years ago when the light from its explosion finally reached Earth. It is a fraudulent companion, but was recently observed as the explosion of the explosion began to fade and exposed a suspicious presence near the dying star.
This cosmic murder mystery has a deep meaning for the astronomers who revealed it. This is the first time anybody has found actual proof that some massive stars, just like those killed in the supernova, can occur in binary systems where they exist alongside a companion star.
This is the very first The documented double star system was discovered by Hubble in "a galaxy far, far away" that lies 40 million light-years from Earth in the Grus constellation, also known as a crane. The name of the galaxy is NGC 7424.
The Hubble photo that brought it all together is the most convincing proof that some supernovae are created in binary systems, "NASA's press release said.

The random Discovery is also described in detail in the published study last month in the Astrophysical Journal
. "We know that the majority of massive stars are binary pairs," said lead author Stuart Ryder of the Australian Astronomical Observatory (AAO) in Sydney, Australia
"Many of these binary pairs interact and transmit gas from one star to another when their orbits bring them close together," he said in the press release.
This was also the case with SN 2001ig the case stellarer companion. SN 2001ig is a rare type of supernova that has been categorized as a type IIb supernova with stripped sheaths, which means that most of the hydrogen is already the "star shell" – the region of the star that has materials from its core in it Atmosphere Transported
The reason was none other than his thieving companion who had been stealing hydrogen from SN 2001ig for millions of years, long before his unsuspecting victim became a supernova.

Similar occurrences are common in the Universe because "sheer The number of stripped-mantle supernovae is larger than predicted," says co-author Ori Fox of the Space Telescope Science Institute in Baltimore.
But Hubble was the first to ever include evidence that binary star systems were long predicted. really exist.
"We were finally able to catch the stellar thief, confirming our suspicion that one had to be there," said study co-author Alex Filippenko of the University of California, Berkeley, who first discovered the IIb striped-envelope supernovae in the year 1987.
