James-Webb scrute Earendel, l’étoile la plus lointaine connue

James-Webb peers into Earendel, the most distant known star

Nasa has just announced that it has imaged the most distant star known to date, as it was 12.9 billion years ago.

It's called Earendel, it's a star observed when the Universe was only 7% of its age, which means that its light collected with the Hubble telescope took 12.9 billion years to reach it.

Earendel was the most massive star at least 50 times the mass of the Sun known.

The theory of stellar structure and evolution tells us that this kind of star can only live for a few million years.

It certainly exploded as a supernova, leaving behind a compact object that must be a neutron star or even a stellar black hole.

We will inform you of all new discoveries about Earendal on Instagram and on our website
