Hubble telescope discovers farthest star so far
The new celestial body is called Earendel, which means morning star in Old English. Its light traveled 12.9 billion light-years through space.

The Hubble Space Telescope detected light from a star that was in a distant galaxy about 900 million years after the Big Bang. At a distance of 12.9 billion light-years, astronomers said it’s the farthest star ever seen by a telescope.
Astronomers named the newly discovered star Earendel, which means morning star in Old English. Now they also want to observe it with the James Webb Telescope, Hubble’s successor, in order to determine its exact age and mass.
The James Webb Telescope, due to be fully operational this summer, is designed to study the early days of the universe. It looks into space beyond the Hubble telescope and thus goes back in time. Astronomers hope that this will allow them to draw conclusions about the formation of the first stars and galaxies.
