  • Study finds gas flowing from black hole could stunt galaxy growth

    Study finds gas flowing from black hole could stunt galaxy growth
    When scientists first theorized about black holes, the idea was relatively simple: Their gravitational pull is so strong, nothing can escape them — not even light. But over the past decade, astrophysicists have wondered whether the full picture...
  • Critters found in Antarctic ice show how tenacious life is

    Deep below the ice, far from the playful penguins and other animals that bring tourists to Antarctica, is a cold and barren world that by all indications should be completely void of life. But recently, scientists researching melting ice watched a half-...
  • Science museums urged to cut ties with fossil fuel donors

    Hundreds of museums across the country including some of the most prestigious are being asked by more than 30 scientists to cut their ties to the fossil fuel industry. In a letter sent to more than 330 science and natural history centers on Tuesday,...
  • Young Jupiter wiped out solar system's early inner planets, study says

    Young Jupiter wiped out solar system's early inner planets, study says
    Before Mercury, Venus, Earth and Mars occupied the inner solar system, there may have been a previous generation of planets that were bigger and more numerous – but were ultimately doomed by Jupiter, according to a new study. If indeed the early...
  • Once-wild Jupiter may explain our unusual solar system

    SAN JOSE, Calif. The neighborhood of our inner solar system wasn't always so lonely. Blame a wild and unruly young Jupiter, which once caromed like a giant billiard ball, shattering early planets and clearing out the once-crowded community around our...
  • Vision quest: Curator catalogs the world's oldest telescopes

    You could say Marvin Bolt takes the long view. He's on a worldwide quest to track down and catalog the oldest telescopes known to man, dating to the early 1600s and the days of Galileo. "You'd think after 400 years, people would know where they are,"...
  • Neil deGrasse Tyson reveals first guests, premiere date for 'StarTalk' show

    Neil deGrasse Tyson reveals first guests, premiere date for 'StarTalk' show
    Everybody's favorite astrophysicist, Neil deGrasse Tyson, is entering the late-night fray in April with a TV version of his hit podcast, "StarTalk." And now we know he'll be joined by an eclectic array of guests on his first few shows. President Jimmy...
  • Ring around the rock? Astronomers say 'centaur' may have debris disk

    Ring around the rock? Astronomers say 'centaur' may have debris disk
    They're a cross between asteroids and comets and they bear the name of the man-horse hybrid from Greek mythology: centaur. Relegated to an otherwise mundane section of our solar system, none of these rocky bodies has ever been observed up close. Their...
  • Eccentric Europe: Offbeat but on-target sights

    Eccentric Europe: Offbeat but on-target sights
    Way back in my student travel days, I discovered a handful of completely offbeat sights that remain among my favorite places in Europe. From sculptures of salt to sculptures of marzipan, from a wall dedicated to love and freedom to chapels decorated...
  • Jupiter's Ganymede has underground ocean: One more 'soggy' moon

    Jupiter's Ganymede has underground ocean: One more 'soggy' moon
    Astronomers have found the most conclusive evidence yet that a large watery ocean lies beneath the surface of Jupiter's moon Ganymede. With the discovery, Ganymede joins Enceladus and Europa as another moon in the solar system with a confirmed...
  • Asteroids and comets play a role in Earth's past, future

    Asteroids and comets play a role in Earth's past, future
    Astronomer and author Phil Plait loves a good disaster flick. What he doesn't love is a disaster flick that gets the science so wrong it's silly. "In any science fiction movie, it's pretty hard to get all the science right," Plait said in a recent...
