It’s the most distant star astronomers have ever seen, “a super-hot, super-bright giant that formed nearly 13 billion years ago at the dawn of the cosmos,” about 900 million years after the Big Bang, Huffington Post says (read story here), adding, “But this luminous blue star is long gone, so massive that it almost certainly exploded into bits just a few million years after emerging.”
It’s not the oldest star the Hubble Space Telescope has observed. But, “While Hubble has spied galaxies as far away as 300 million to 400 million years of the universe-forming Big Bang, their individual stars are impossible to pick out.” That does mean, though, that other stars formed hundreds of millions of years before this one.
The star’s distance and age were determined by calculating redshift. Some people may not like hearing the universe is older than 6,000 years, but it is. The fact something conflicts with what they want to believe doesn’t make it untrue. Hubble isn’t hallucinating, and math doesn’t lie.
