Jupiter is our solar system’s resident behemoth. It’s an enormous planet that has more mass than all the others combined, not to mention the largest gravitational and magnetic influence in the solar system (besides the Sun, of coourse.) It’s no wonder that it also has the most moons in orbit around it than any of…

First GRAIL Video Shows Moon’s “Dark Side”
See you on the dark side of the Moon*! NASA’s GRAIL mission has beamed back its first video of the far side of the moon. The imagery was taken on Jan. 19 by the MoonKAM aboard the mission’s “Ebb” spacecraft. GRAIL consists of two identical spacecraft, recently named Ebb and Flow, each of which is…
Giant Asteroid to Approach Earth Jan. 31
It’s huge – 21 miles across! It’s bright – magnitude 8.7, maybe more! And right now it’s coming close to Earth – the closest it’s come in 37 years! Why haven’t they told us about this?!? Well, actually they have. It’s asteroid 433 Eros, and on Tuesday it will come within 16.6 million miles of…
Hello, Earth!
It’s the 2012 version of the “Blue Marble“! Here’s an amazing new high-definition portrait of our planet, made by NASA’s Suomi NPP satellite launched back on October 28. This is a composite image created from multiple scans taken with the satellite’s Visible/Infrared Imager Radiometer Suite (VIIRS). Suomi NPP is the first satellite designed to collect…
Solar Storm in Progress!
Yesterday’s solar flare sent out a huge cloud of charged solar particles our way, and this afternoon it impacted our magnetosphere… sparking a brilliant display of aurorae in northern skies such as those above the Aurora Sky Station in Abisko, Sweden.
Time For Some Stormy Solar Weather!
Any lapse in solar activity we may have seen during this period of “solar maximum” came to an end this weekend with some very energetic flares and CMEs, including the one seen above: an M8.7-class flare spotted by NASA’s Solar Dynamics Observatory (SDO) at 3:49 UT this morning. This comes just 4 days after a…
No Doom in 2012: Stop the Insanity!
Now that’s we’re officially three days into 2012, the ‘net is already abuzz with talk of impending doom on December 21 of this year. Luckily there are plenty of science sources that are more than happy to offer fact-based consolation that there is no actual evidence that anything cosmically bad is expected to occur on…
Happy New Year from the ISS!
2011 has given us many amazing images and videos of our planet from the International Space Station, which received its last US-built components this year during the STS-133 and 134 shuttle missions. The Expedition 30 crew now aboard the ISS will ring in 2012 from orbit, and they have recorded the video above to wish…
A Beautiful Comet-rise at Dawn (VIDEO)
The video above contains a time-lapse movie of Earth’s horizon at dawn on December 21, showing lightning storms, stars, airglow… and the sungrazing comet Lovejoy rising above the atmosphere! (And I must say its new tail looks amazing!)
Breaking News: Kepler Team Spots First Earth-Sized Exoplanets
The video above sums up the big astro-news of the day: NASA’s Kepler mission has confirmed the existence of not one but TWO Earth-sized planets orbiting a Sun-like star 1,000 light-years away. This is a big deal!
The Colors of Titan’s Sky
Made from one of the most recent Cassini images, this is a color-composite showing a backlit Titan with its dense, multi-layered atmosphere scattering sunlight in different colors. Titan’s atmosphere is made up of methane and complex hydrocarbons and is ten times as thick as Earth’s. It is the only moon in our solar system known to have…
Comet Lovejoy’s Dazzling Death Dive
The end is definitely near… for comet Lovejoy, at least. The bright sungrazing comet was discovered on December 2, 2011, by Australian amateur astronomer Terry Lovejoy using a ground-based telescope. It was quickly seen that the comet was on a doomsday dive toward the Sun and will not likely survive its close pass of our…
