The new record holder for the most distant galaxy is an amorphous blob of billions of stars whose light took more than 13 billion years to reach Earth. Dubbed EGS-zs8-1, the galaxy sits in the constellation Boötes and is the brightest known galaxy in the early universe, researchers report May 5 in the Astrophysical Journal Letters. EGS-zs8-1’s brightness indicates that the galaxy had already built up roughly 8 billion suns when the light left for Earth.
By studying a galaxy as it was when the universe was a mere 650 million years old, astronomers hope to better understand how seeds of gas and dark matter eventually grow to the majestic spiral and elliptical galaxies that exist today.
