NASA’s Hubble Space Telescope has discovered a strange star in our galaxy. Astronomers have nicknamed it nasty because of its weird behavior.
“Nasty 1” will help the astronomers to disclose the stages of evolution of big stars in the universe. The star was first discovered several decades ago and was named Wolf-Rayet star. NASA astronomers say that the hydrogen filled outer space of the star erodes quickly, exposing its hot and bright helium core.
The researchers also discovered that it does not look like a Wolf Rayet star. The nebula surrounding the star is estimated to be a few thousand years old and about 3,000 light years from the earth. According to the astronomers, the disc is the result of a rare occurrence wherein two Wolf-Rayets from within the same solar system and one star’s hydrogen is siphoned off by its smaller companion.
“We were excited to see this dislike structure because it may be evidence for a Wolf-Rayet star from a binary interaction,” said Jon Mauerhan, study lead author from University of California, Berkeley. There are few examples in the galaxy of this process in action because this phase is not living perhaps lasting only a few hundred years, while the timescale over which a resulting disk is visible could actually be ten thousand years.
