Jakarta –
If you see clusters bintang To the naked eye, of course, there are lots of stars that look very similar to each other. However, in reality there are stars that appear in different colors.
Most stars appear white, some red, and some blue. These colors represent information about temperature and time. Reported detikINET From space, blue stars have the hottest temperatures and largest masses, making them appear the brightest.
Blue stars are short-lived due to heat
However, the actual composition of each star remains the same, i.e. 75% hydrogen, 24% helium and several other elements. However, blue stars have more massive activity and greater luminous capacity.
The blue color of stars is also caused by the very high temperatures in various blue stars. This means they are very massive and emit a lot of energy into space which will eventually burn the star itself. As a result, blue stars are usually short-lived.
Scientists say that virtually all stars that can be seen today are stars that are in the first phase of their evolutionary sequence. In this phase, stars convert hydrogen into helium through nuclear fusion. The length of time stars remain in this phase depends on the mass of the star.
Therefore, blue stars are stars that burn “themselves” faster than other stars. The energy emitted by the blue star is estimated to be 60,000 times greater than that of the sun.
The most famous blue star
There are three most famous blue stars in the universe. The first is Regulius which is found in the constellation of Leo, the second is the star Spica which is found in the constellation of Virgo and then the star Rigel which is found in the constellation of Orion is the brightest.
The star Regulus is 79 light-years from Earth, the star Spica is 250 light-years from Earth, and the star Rigel is 860 light-years from Earth.
