Our solar system is incredibly old according to human standards. It is believed that the center located in the center is just over 4.6 billion years, and this is an almost unbelievable time for you and I. But that's not all that is spectacular when it comes to stars.
A new study on one particular star in our own Milky Way galaxy reveals that it is much older than anyone thought. In fact, it's old enough to compare our own star as a baby. The old star is called (deep breathing) 2MASS J18082002-5104378 B, and it lacks the glittering name of more than age. Now astronomers believe it's incredible 13.5 billion years old.
2MASS J18 … do you know what? Let's find out just about the "Old Star". The old star gave birth to its age, thanks to the incredibly low mass and metal content. Researchers believe that the latest stars tend to be very high in metal, but Old Star's metal content is incredibly low. It's also very small, weighing only about 1/10 of our own Sun mass.
"We never found such a low mass star and made so few meters in meters," said astrophysicist Andrew Casey, co-author of the study Astrophysics magazine, ScienceAlert said. "This discovery suggests to us that there were no massive stellar stars that had been dead for a long time in the universe, for all the first stars in the universe. These ancient stars can be made up of very small volumes of material, which means that some of these relics could still exist today after the Big Bang. "
So how was the star able to stay alive for so long? Well, the small size is really good, because very big stars burn fuel much faster than the small ones. Old Star only stops the known mass limit to facilitate hydrogen burning, so it's very slow in using its fuel for over a billion years.
Because of its small size and brilliance, it was hard to spot, and the team suggests that there could be many other ultra-old stars that are sitting in oblivion and remain undetected, because we simply can not see it.
