NASA’s Hubble Telescope Discover Farthest Star Yet

NASA announced that a group of astronomers has identified the furthest star yet discovered, a blue giant that originated nearly 13 billion years ago at the beginning of the cosmos using the Hubble Space Telescope, 

The newly discovered star was named Earendel, an Old English name that means morning star or rising light, “a fitting name for a star that we have observed in a time often referred to as ‘Cosmic Dawn.′ ” said astronomer Brian Welch, lead author of the study that led to the discovery.

“We’re seeing the star as it was about 12.8 billion years ago, which puts it about 900 million years after the Big Bang,” Welch revealed.

Icarus, another blue supergiant star discovered by Hubble, held the previous record at 9.4 billion years, which was more than 4 billion years since the Big Bang.

Astronomers magnified the distant starlight in both cases using a method known as gravitational lensing wherein gravity from clusters of galaxies closer to us in the foreground serves as a lens to magnify smaller objects in the background.

According to current data, Earendel was more than 50 times the size of our sun and a million times brighter than Icarus.

Welch speculated that Earendel could have been the brightest star in a two-star, or binary, system, or perhaps a triple- or quadruple-star system, he also observed that there’s a slim probability it’s a black hole, yet observations from 2016 and 2019 suggest otherwise.
