What Is The Hottest Star In The Universe

With increase in temperature the star turns bluish in color.

The stars with temperatures higher than 60 000 k are included. Star name effective temperature mass m luminosity l spectral type distance light years. The hottest star wr 102 image. This is a list of hottest stars so far discovered excluding degenerate stars arranged by decreasing temperature.

The star wr102 is a blue star with surface temperature of over 2 10 000 kelvin is the hottest star ever recorded. But the hottest known stars in the universe are the blue hypergiant stars. However supernovae aren t the hottest things in the universe not even close. Nasa esa hubble with a surface temperature of 210 000k compared to 6 000k for the sun wr 102 shown here illuminating the nebulosity that surrounds it situated 9 800 light years away in the constellation sagittarius is the hottest known star.

However the hottest star wr 102 is an especially rare wo type wolf rayet which is a late stage star that has a surface heavily enriched with ionized oxygen. The largest stars in the universe compared to our sun hottest star ever discovered. Another contestant for the hottest temperature in the universe comes courtesy of string theorists who say that the hottest temperature is 10 30 k a little cooler than the contestant above. All said astronomers only know of.

The hottest stars have surface temperatures of 50 000 kelvin degrees.
