Sky at a Glance | November 23rd, 2012
The Moon joins up with Jupiter and Aldebaran, and undergoes a penumbral eclipse for the West Coast and then lands across the Pacific. In the dawn, Saturn skims past Venus.
Making Mini-Oort Clouds
A new set of simulations shows that systems with so-called "hot Jupiters" might also have mini-Oort clouds detectable by today's space telescopes, giving astronomers a new potential tool for finding exotic extrasolar systems.
A Planetary Nebula Reborn — For a While
A stunning image from the Hubble Space Telescope and Chandra X-ray Observatory reveals a planetary nebula come back to life.
Sky at a Glance | November 16th, 2012
Jupiter rises in twilight, the Moon waxes across the evening sky, and Saturn approaches Venus in the dawn.
The 2012 Leonid Meteor Shower
The annual Leonids should peak early Saturday morning. While they probably won't make a big impression this year, an absent Moon and the possibility of a second meteor peak next week raise the cool factor.
Tilt a Black Hole and Watch What Happens
A simulation published in yesterday's Science shows how black holes govern their surroundings. Watch a black hole work its magic in this new video.
Asteroid Pieces Make Pretty Meteorites
A new analysis of crystals in pallasite meteorites suggests that these beautiful objects had a violent birth — but one quite different than scientists had imagined.
DSLR Planet Imaging How-To
Everything you'll need to know to shoot the planets with your DSLR.
Portable Paramount Pier
A sturdy new solution for taking your Paramount MX on the road.
Totality Down Under
The total solar eclipse on November 13-14 drew tens of thousands of umbraphiles to northeastern Australian and onto several ships in the South Pacific.
Not in Australia? Watch Today's Eclipse Online
Watch today's total solar eclipse even if you haven't traveled Down Under. At 3:35 p.m. EST, the Moonwill cover the Sun for a maximum of 4 minutes and 2 seconds. Two sites will let you see the spectacle live online.
Cosmic Web Weeds Dwarf Galaxies
Astronomers have discovered an unexpected explanation for why they can only find a small fraction of the satellite galaxies the Milky Way is supposed to have.
Sky at a Glance | November 9th, 2012
Jupiter rises before dark, Fomalhaut culminates early, Orion rises a bit later, and the crescent Moon moves from dawn back to dusk.
A New Goldilocks Planet
Astronomers have found a system of six super-Earths, one of which is at the "Goldilocks" distance for sustaining liquid water. The Sun-like host of the system lies only 40 light-years away.
Making the Moon Anew
One of the solar system's most nagging problems literally stares into the collective faces of planetary scientists on many nights every month. It's the Moon — or, specifically, how it came to exist.
Explaining Cosmic Butterflies
Planetary nebulae, left behind by stars like our Sun, come in chimerical shapes. New observations confirm that many of these shapes may have a common explanation.
