Telescopes Uses Ripples in TIME

The first JWST image of Earendel, the most distant star known in our universe, 
lensed and magnified ... NASA, ESA, CSA, STSCI



Scientists using the James Webb Space Telescope (JWST) have imaged the most distant star ever observed thanks to a a ripple in spacetime that creates extreme magnification.


It’s currently 28 billion light-years away and its light has traveled 12.9 billion years into JWST’s optics. It existed just 900 million years after the big bang in a galaxy astronomers have nicknamed the Sunrise Arc.

The image of WHL0137-LS, above, was produced from over three hours of observations last weekend—but it’s not the star you think! Ignore the spiky star and instead go to the lower right-hand side (see below).


The ancient star is estimated to have a mass greater than 50 times the mass of the Sun.


Better known as “Earendel,” which means “morning star” or “rising light” in old English—was gravitationally lensed and magnified by a massive galaxy cluster called WHL0137–08 (a.k.a. “Sunrise Arc”) in the foreground.  READ MORE...
