Scientists reveal the surprising genetic identity of early human remains from roughly 400,000 years ago in Spain (Atapuerca). New tests on human bones hidden in a Spanish cave for some 400,000 years set a new record for the oldest human DNA sequence ever decoded—and may scramble the scientific picture of our early relatives. The bones were first thought to belong to European Neanderthals, but analysis showed they are genetically closer to the Siberian Denisovans.
Hoag's Object is a mysterious ring galaxy 600 million light years away in the constellation Serpens. The outer ring is composed largely of hot blue stars, while the core is older red and yellow stars. The space in between is almost completely dark. It is thought that this galaxy formed from the collision of two galaxies billions of years ago. Visible near the top of the gap is another ring galaxy, likely much further away.
