Sky Telescope Noticas recientes

When you head outdoors tonight, take Sky & Telescope's podcast with you for a guided tour to the night sky. Learn what constellations are visible, find out where and when you'll see the planets, and catch each month's celestial highlights, from meteor showers to eclipses.
  1. Coastal waves from mid-sized asteroid impacts might be more like a storm surge than a wall of watery destruction, according to NASA experiments with paintballs.

    The post Paintballs Clarify What Happens When an Asteroid Hits Earth’s Ocean appeared first on Sky & Telescope.

  2. One of the closest stars to the Sun hosts a planet at least three times as massive as our own where temperatures might be just low enough to freeze liquid water.

    The post A Chilly Super-Earth May Orbit Barnard’s Star appeared first on Sky & Telescope.

  3. Now you see it, now you don't. McNeil's Nebula in Orion has disappeared, thanks to a drastic reduction in brightness from the protostar that usually provides illumination. 

    The post The Case of the Vanishing Nebula appeared first on Sky & Telescope.

  4. A low-mass sun with few elements heavier than helium provides hope that the Galaxy might contain survivors from the very first generation of stars. 

    The post Puny Star Might Be Specimen from Early Universe appeared first on Sky & Telescope.

  5. Arizona comet hunter Don Machholz did it again! He discovered his 12th comet only two mornings ago. Set your alarm, grab your scope, and take a look.

    The post Amateur Don Machholz Discovers His 12th Comet! (Updated) appeared first on Sky & Telescope.

  6. Electrostatic discharge in a simulated dusty Martian environment yields perchlorates — a potential energy source for microbial life — at abundances 1,000 times greater than sunlight alone.

    The post Dust Storm Electricity Might Forge Perchlorates on Mars appeared first on Sky & Telescope.

  7. A recent study has discovered three of the fastest stars — white dwarfs — known in the Milky Way. But these stars may be more than just speeders — they might also be evidence of how Type Ia supernovae occur.

    The post Speeding White Dwarfs May Point to Past Explosions appeared first on Sky & Telescope.

  8. Astronomers have suspected for some time that the Large and Small Magellanic Clouds collided in the recent past. The Gaia space telescope provides striking new evidence for a head-on collision.

    The post Evidence Mounts for a Magellanic Collision appeared first on Sky & Telescope.

  9. Astronomers have detected three flares from near our galaxy’s central black hole that look like gas closely orbiting the unseen object.

    The post Gas Seen Moving Near the Event Horizon appeared first on Sky & Telescope.

  10. Take a look behind the scenes as the New Horizons team gears up for the historic first flyby of a body in the remote Kuiper Belt, in this first of a four-part series from the mission's Principal Investigator Alan Stern.
