A Portrait of Earth and the Moon from 4 Million Miles Away

21 years ago today, December 16th, 1992, NASA’s Galileo spacecraft took this image of Earth and the Moon from a distance of about 3.9 million miles (6.2 million km). It’s one of the few images ever captured that singularly show both worlds in their entirety. And to think that when this image was taken, our…

There’s a Jade Rabbit on the Moon!

There’s a rabbit on the Moon! A robot rabbit, that is — China’s Yutu rover (named after the mythological jade rabbit pet of the lunar goddess Chang’e) successfully deployed from the Chang’e-3 lander earlier this afternoon, completing the country’s first successful lunar landing and the first soft touchdown on the Moon by any nation since…

Jupiter’s Moon Europa Has Jets Like Enceladus!

“Attempt no landings there?” Ok, FINE. We’ll just fly a spacecraft through Europa’s newly-discovered plumes and get a taste of its underground ocean that way! Because it has them, and so we could. This was the big news from NASA, ESA, and Hubble researchers today: Jupiter’s ice-covered moon Europa (yes, the one from 2010) has…

Fly Over Titan’s “Land O’Lakes”

By now you probably know about the lakes of liquid hydrocarbons on Titan. Thanks to Cassini, we know that Saturn’s largest moon is the one other place in the solar system where liquid can be found in stable amounts on the surface, except that it’s not water like we have here on Earth, but rather…

Cassini’s Best Look Yet At Saturn’s Crazy Hexagon

Yes, I said hexagon. If you haven’t heard, our solar system’s second-largest planet has another curious feature besides its sprawling rings; it’s also in possession of an uncannily geometric six-sided jet stream encircling its north pole — at the heart of which lies a churning hurricane-like vortex over 1,800 miles wide. This hexagon has been…

So… What’s Up With ISON?

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…
