Discovery of the "Most Pristine" Star
Astronomers have discovered a surprisingly "pristine" red giant with the lowest concentration of heavy elements ever seen in a star, likely a direct descendant of one of the universe's first stars.
This unusual star, found near the edge of the Milky Way, breaks a major rule of star formation due to its extremely low metal content.
- All known stars are powered by nuclear fusion.
- This process combines lighter elements into heavier ones, releasing large amounts of energy.
- A common example is hydrogen fusing into helium, the most abundant elements in stars.
The unusual alien sun, which could be the offspring of one of the universe's first stars, is so metal-poor that it breaks a major rule of star formation.
Astronomers may have just discovered the "most pristine" star ever seen, lurking near the edge of the Milky Way.
