NASA Recently Found the Farthest Star Ever Seen, Thanks to a Ripple of Space-Time

Posted by in category: space

Like something out of a sci-fi movie, the Hubble Space Telescope discovered the most distant star ever seen—through a cosmic fluke.

Nicknamed “Earendel,” the star’s light took 12.9 billion years to reach Earth, and scientists believe it emitted light throughout the first billion years of our universe’s existence. Beside its age, Earendel’s position is also curious. According to NASA, Hubble was able to detect the star thanks to gravitational lensing, a phenomenon in which a massive object (like a galaxy) warps the fabric of space. When light reaches the warped space, it can act like a magnifying glass and highlight objects we’d otherwise have a difficult time seeing.

And that’s how Earendel—whose Old English name is akin to “morning star” or “rising light”—was found (though Tolkien fans will recognize it as a riff on Eärendil, the half-Elven seafarer who carried a Silmaril).
