Each is classified as an O-type star — and O-type stars are the rarest main sequence stars in the universe, comprising just 0.00003% of known stars. They’re extremely prone to going supernova and collapsing into black holes or neutron stars.
Are there any blue stars?
Blue stars are stars that have at least 3 times the mass of the Sun and up. Whether a star has 10 times the mass of the Sun or 150 solar masses, it’s going to appear blue to our eyes.

What is a failed star?
A celestial body that is similar to a star but does not emit light because it does not have enough mass to ignite internal nuclear fusion.
What Colour is water?
While relatively small quantities of water appear to be colorless, pure water has a slight blue color that becomes deeper as the thickness of the observed sample increases. The hue of water is an intrinsic property and is caused by selective absorption and scattering of white light.
What color Is A Mirror?
As a perfect mirror reflects back all the colours comprising white light, it’s also white. That said, real mirrors aren’t perfect, and their surface atoms give any reflection a very slight green tinge, as the atoms in the glass reflect back green light more strongly than any other colour.
Who named Planet Earth?
All of the planets, except for Earth, were named after Greek and Roman gods and godesses. The name Earth is an English/German name which simply means the ground. It comes from the Old English words ‘eor(th)e’ and ‘ertha’. In German it is ‘erde’.

Does Sun is a star?
Our Sun is an ordinary star, just one among hundreds of billions of stars in the Milky Way Galaxy. As the only star we can observe in detail, it provides a basis for our understanding of all stars. The Sun is composed almost entirely of hydrogen and helium gas.
What is largest star in Milky Way?
The largest of all
The star lies near the center of the Milky Way, roughly 9,500 light-years away. Located in the constellation Scutum, UY Scuti is a hypergiant, the classification that comes after supergiant, which itself comes after giant. Hypergiants are rare stars that shine very brightly.
How many galaxies are there?

What is a yellow star?
Jews throughout Nazi-occupied Europe were forced to wear a badge in the form of a Yellow Star as a means of identification. … The star was intended to humiliate Jews and to mark them out for segregation and discrimination. The policy also made it easier to identify Jews for deportation to camps.
