Even the most powerful high-tech telescopes are barely able to record remote low-mass and thus faint stars.... full story »

Tycho's Star Shines in Gamma Rays, NASA's Fermi Shows
In early November 1572, observers on Earth witnessed the appearance of a "new star" in the constellation Cassiopeia, an event now recognized as the brightest naked-eye supernova in more than 400 years. It's often called "Tycho's supernova" after the great Danish astronomer Tycho Brahe... full story »
