Hubble reveals the most distant star ever detected

-----------------------------------

"The most distant star — or possibly pair of stars — that astronomers have ever seen was just revealed thanks to the Hubble telescope and a massive cluster of galaxies. The far-away star system takes the official name WHL0137-LS, but the astronomers who found it nicknamed it “Earendel” from the Old English word meaning “morning star” or “rising light.”

Earendel system as we’re seeing it today was shining within just 900 million years of the Big Bang, according to the authors of a new paper in the journal Nature describing the discovery. Fully 12.8 billion years passed before that light reached the Hubble Space Telescope, magnified by a lucky trick of gravity to appear as a tiny smudge of photons on Hubble’s image sensor. Earendel is 8.2 billion years older than the Sun and Earth and 12.1 billion years older than our planet’s first animals."
