On cloudless, moonless nights, the stars are so bright over the remote village of Sutherland, South Africa, that a person can walk by starlight alone. Learn more about the village’s Southern African Large Telescope (SALT).
Our eyes can only detect a fraction of light in the electromagnetic spectrum — otherwise we’d see gamma-ray bursts, flashes that outshine the sun by a million trillion times, about once a day. Learn more.
Scientists have been studying brown dwarfs, or failed stars, for nearly a century. What have they learned? And what answers are they still seeking about these objects stuck somewhere between stars and planets?
In early 2004, two unlikely explorers traveled to the red planet and found strong evidence to confirm water once existed on the surface of Mars, and in sufficient quantity to possibly have harbored life.
So much of what drives cosmic exploration involves the quest to learn whether or not we're alone in the Universe. But that's not the only reason to go to Mars. Find out others from Neil deGrasse Tyson.
