Yesterday sure was interesting. As the astronomical world, from scientists to journalists to enthusiasts alike, watched online in near real time as ISON came within its closest pass of the Sun — in literally ever — the comet, having spent the previous several hours brightening steadily, suddenly went dim as it traveled deep into the…

Questions About ISON? Here Are Some Answers:
Unless you’ve been living in the Oort Cloud you’ve probably heard about the current travels of comet C/2012 S1 (aka ISON) through the inner solar system. Although this soon-to-be “sungrazing” comet was first spotted by astronomers Vitali Nevski (from Belarus) and Artyom Novichonok (Russia) on Sept. 21, 2012, it’s actually been on its way toward the…
The Other Side of ISON: Here’s the Comet as Seen from Mercury
While many skywatchers, scientists, and astronomy enthusiasts around the world wait to see if comet ISON survives its perihelion — that is, its closest pass by the Sun — on Nov. 28, the MESSENGER spacecraft has captured an image of the incoming comet from its position in orbit around Mercury! The image above, shared today…
Watch this beautiful new trailer for “In Saturn’s Rings”
It’s a labor of love: using hundreds of thousands of real images taken by NASA’s Cassini, Galileo, Voyager, and other space exploration missions to create a stunning feature-length, high-definition IMAX movie that showcases the beauty of our Solar System on the big screen like never before. This is the achievement of “In Saturn’s Rings,” a…
Happy Birthday, ISS!
It’s been 15 years since the first piece of what we now know as the International Space Station left the surface of our planet. It was Russia’s Zarya module, launched aboard a Proton rocket on Nov. 20, 1998, and the U.S. followed suit two weeks later with the Unity module sent aboard the shuttle Endeavour….
The 2014 Year in Space Calendars are Here!
And you will want one! (Trust me on this.) Produced by Starry Messenger Press in conjunction with The Planetary Society, the 2014 Year in Space calendar is (like its 2013 version) a gorgeous 16″ x 22″ (40.5 cm x 56 cm) work of art filled with over 120 images of space exploration and hundreds upon…
What Happened to Mars?
Mars wasn’t always the cold, dry world that it is today — billions of years ago it likely looked a lot more like Earth, with seas and rivers of liquid water on its surface and a thick atmosphere with air and clouds. But something happened over the course of Mars’ history to transform it from…
OMG Saturn.
Go get some extra socks handy because this new image of Saturn is going to knock ’em clean off your feet. Seen in eclipse against the light of the Sun, Saturn and its rings seem to glow with a magical light in this picture, painstakingly assembled from 141 separate wide-angle images taken by the Cassini spacecraft…
Astronomers Spot an Asteroid Sporting Six Comet-Like Tails
If you thought tails were just for comets and cats, this asteroid is about to prove you wrong. On August 27 astronomers spotted an unusually fuzzy looking object in survey images taken with the Pan-STARRS telescope in Hawaii. The multiple tails were discovered in Hubble images taken on September 10, 2013. When Hubble returned to…
Vesta’s Formation History? It’s Complicated.
Just when scientists thought they had a tidy theory for how the giant asteroid Vesta formed, a new paper from NASA’s Dawn mission suggests the history is more complicated. If Vesta’s formation had followed the script for the formation of rocky planets like our own, heat from the interior would have created distinct, separated layers…
NASA’s Surprising Discoveries About Three Near-Earth Asteroids
Every few days or so I like to check the “Close Approaches” page of JPL’s Near-Earth Object Program, just to see what sorts of cosmic objects are whizzing by our planet; how big they are, when they’ll come, and how far they’ll (hopefully!) miss us by. Most of them are relatively small asteroids several dozen…
