Blue Stars In Space

Rare ultra blue stars found in neighboring galaxy s hub.

Blue stars in space. Whether a star has 10 times the mass of the sun or 150 solar masses it s going to appear blue to our eyes. They can have as few as 10 stars or as many as several thousand eso officials wrote. While blue giant stars have a surface temperature of at least 10 000 kelvin compared to say a yellow dwarf star like our sun at about 6 000k another type of star called blue supergiants class i are even more extreme with a surface temperature of between 10 000 50 000k and luminosities of 10 000 to a million times brighter than the sun.

Stars usually form in clusters like this one. Peering deep inside the hub of the neighboring andromeda galaxy nasa s hubble space telescope has uncovered a large rare population of hot bright stars. But they re still everywhere as if recently created.

Traditional astronomy tends to group stars into constellations or asterisms and give proper names to those not to individual stars. Many star names are in origin descriptive of the part of the constellation they are found in. The term applies to a variety of stars in different phases of development all evolved stars that have moved from the main sequence but have little else in common so blue giant simply refers to stars in a particular region of the hr diagram rather than a specific type of star.

The more we learn about the universe the more we marvel at the extraordinary number and diversity of stars. Among the kaleidoscope of stars brilliant blue stars are of special interest. They shine so brightly that they should burn up their fuel in just a few million years.

Stars planets galaxies clouds of dust and gas and other matter in space are sending out energy all the time. In the standard hertzsprung russell diagram these stars lie above and to the right of the main sequence. Blue stars are stars that have at least 3 times the mass of the sun and up.

In astronomy a blue giant is a hot star with a luminosity class of iii giant or ii bright giant. Like waves traveling through the ocean they can be very long and lazy very short and peppy or anything in between. Of the roughly 10 000 stars visible to the naked eye only a few hundred have been given proper names in the history of astronomy.
