They've nicknamed it "Earendel" and it's the most distant, single star yet imaged by a telescope. The light from this object has taken 12.9 billion years to reach us. It's at the sort of distance that telescopes normally would only be able to resolve galaxies containing millions of stars. But the Hubble space observatory has picked out Earendel individually by exploiting a natural phenomenon that's akin to using a zoom lens.
