The First Star?

The topic of which of observed stars is the oldest arises when we talk about stars. Could we possibly know, considering that it is likely that a star of this type would have gone supernova long ago, condensed into one of those ultra-dense neutron stars, or became a black hole. The first stars are still just hypothetical.

Because of the theory that suggests that their extended lives have stripped them of all heavy components, these stars are known as Population III stars and are largely undetected by methods that are currently available (calcium, magnesium, etc.). The star we revolve around is a Population I-type, which is a very young star and, by cosmic standards, is full of the heavier components believed to have given rise to Earth, Mercury, Venus, and other planets.

As of today, AS0039, which is 290,000 light years away, is thought to be the oldest star known to man. It is thought to have been a remnant of a truly enormous star, perhaps 20 times as massive as our sun, that went hypernova, an event that is 10 to 100 times more intense than a supernova.

Extrapolating from the fact that AS0039 is not only devoid of metal atoms but also remarkably light on heavy gases like carbon, one might conclude that it may have existed during the first billion years of the universe. It certainly seems as though AS0039 has the solar version of osteoporosis.
