It may be home to “Population III” stars. 💫
the galaxy candidate is about 13.5 billion light-years away and was described Thursday in This is interesting in and of itself, but it gets better; it may be home to"Population III" stars. These are postulated to be the first kind of stars ever born which have never been observed, until possibly now. Another view is that the galaxy could also be home to a supermassive black hole roughly 100 times the mass of our Sun.
The newly discovered galaxy is very bright in the ultraviolet part of the electromagnetic spectrum. This is odd but could be explained by, “some energetic processes are occurring there or, better yet, did occur some billions of years ago,” Pacucci says. “The very first population of stars that formed in the universe were more massive, more luminous, and hotter than modern stars,” Pacucci says. “If we assume the stars produced in HD1 are these first, or Population III, stars, then its properties could be explained more easily. In fact, Population III stars are capable of producing more UV light than normal stars, which could clarify the extreme ultraviolet luminosity of HD1.” instead.
