is pollux likely to become a supernova
Recently, astronomers discovered that the star has an extrasolar planet, or exoplanet. As it is not massive enough to go out as a supernova, Pollux will end its life by expelling its outer layers to form a planetary nebula, leaving behind a compact white dwarf. Arrows indicate directions of movement. Pollux b was given the proper name Thestias, after Leda, the mother of Castor and Polydeuces in Greek mythology. Gamma Velorum lies 800 light-years away in the constellation, Vela. Subscribe to our daily newsletter to keep in touch with the subjects shaping our future. The planet (known as Beta Genorium b) is much larger than Earth about 1.6 times the size of Jupiter and also orbits slightly farther away from Pollux than Earth does from the sun.

Constellation Lupus brightest star, Alpha Lupi, may be the next star to go supernova. The name Pollux comes from Greek and Roman mythology. Stars in the mass range of Deneb eventually expand to become the most luminous red supergiants, and within a few million years their cores will collapse producing a supernova explosion. A dazzling supernova will appear in the sky in 2022, predict astronomers. The Jellyfish Nebula (IC 443) is a supernova remnant that can be seen at Castors foot, between Tejat and Propus (Mu and Eta Geminorum) and not far from the Monkey Head Nebula (NGC 2174) in the constellation Orion. Because planet-hunting was relatively new in 2006 this was before the Kepler planet-hunting space telescope launched into orbit, for example astronomers were quite excited by the find.

Spicas explosion would be seen in broad daylight for several weeks. Like other red giants, this process causes Pollux to become cooler than our Sun hence its orange color and much larger: 10 times the diameter of the Sun. M1 is the remains of a star that went supernova in 1054, an event recorded by Chinese and Japanese astronomers. When that light does arrive, the intensity of the supernova, as seen here on Earth, is somewhat a debate. A stars mass is determined by the amount of matter that is available in its nebula, the giant cloud of gas and dust from which it was born. Spica is the Virgo constellations brightest star. For Pollux to go supernova, it would have to be of much bigger mass. The X-rays were produced by a jet launched from the core of the star at the moment of its collapse. They were later also associated with Hercules (Pollux) and Apollo (Castor). By stellar standards, thats super-short, but there are kinds of stars that can go supernova. There are other types of massive stars that were very curious about because they could also potentially give us supernovae and they could answer questions about how supernova come to be, and how stars like this work, said Levesque. It is an orange-hued evolved giant star, and also the closest giant star to the sun at a distance of only 34 light-years.
