All I can say is ” 🙂 “. On its way back for its third and last flyby on Nov. 13, 2009, the European Space Agency’s Rosetta spacecraft captured this beautiful photo of our planet. The illuminated crescent shows the south polar region, with some of Antarctica’s sea ice reflecting brightly through the swirling clouds….

Sun Dance
This mesmerizing animation by photographer Alan Friedman shows a solar prominence as it changes structure over the course of 78 minutes. Solar prominences are eruptions of hot gases extending from the sun’s surface, held together by magnetic forces which constantly shift and move. They can last for days or months, and extend thousands and even…
Now that’s a big shadow!
This was a suprising find amongst the raw images from Cassini this evening….a photo of Saturn, similar to the one I posted previously, but with a massive shadow cast upon its southern hemisphere. I presume it’s from Titan, somewhere out of frame, based upon its size and hazy edges (indicative of the big moon’s thick…
KAGUYA’s Lunar Legacy
On Monday JAXA released more footage taken by the KAGUYA orbiter during its lunar mapping mission. KAGUYA spent several months flying over the moon at altitudes ranging from 10-50km (about 6-30 miles) taking video with its high-definition camera before finally ending its mission and crash landing onto the moon on June 10, 2009. The sequence…
Now With 6% More Mercury!
With the third and last flyby of Mercury by the MESSENGER spacecraft, NASA scientists have now imaged nearly 98 percent of the surface of the first planet from our sun. The photo above shows a color-calibrated view of a crescent Mercury, acquired on September 29. This will be the last close-up color image of Mercury…
No Editing Required
This raw image from Cassini requires no editing to be presentable…..it’s simply a beautiful shot of Mimas hovering in front of the rings with Saturn’s shadow cast across them. Simple, untouched beauty at its best. That little Cassini….he’s getting good at this. 🙂 Image: NASA/JPL/Space Science Institute
Billions and Billions
Talk about lights in the dark! The image above is a low-res version of what amounts to 22 months of dedicated work by Central Michigan University astronomer Axel Mellinger, traveling across the United States and South Africa and assembling over 3,000 individual images to create the most extensive and detailed – and zoomable – portrait…
Sister Moons
Little Tethys is getting a lot of face time in front of Cassini’s lens. In this photo, from a raw image taken on October 17, Tethys passes across the hazy face of her much larger sister, Titan. 662-mile-wide Tethys is dwarfed by the 3,200-mile-wide Titan, although the distance that separates them in this image reduces…
Full Moon
Here’s an amazing portrait of Tethys, a 662-mile-wide, airless and  heavily-cratered moon of Saturn. The photo was taken by Cassini on October 14, 2009, with the moon fully lit by the sun. Its high reflectivity (albedo) indicate a large amount of ice in its composition. I adjusted the image to bring out the details in…
A Rhea View
Here’s an amazingly detailed view of the extensively cratered surface of Rhea, Saturn’s second-largest moon, taken during a particularly close encounter by Cassini on October 13, 2009. About 950 miles wide Rhea is less than a third the size of Titan, Saturn’s largest moon. Unlike Titan, Rhea has no atmosphere at all to speak of…
First Rock From The Sun
While approaching the planet for the third flyby of its mission, the MESSENGER spacecraft took this photo of Mercury, crescent-lit by the sun and showing terrain that has never been imaged before. The region along the planet’s limb, the brightest area seen here, had yet to be mapped by the spacecraft’s cameras. It contains many…
A Beautiful Demise
I don’t usually post images of deep-space objects here but I had to make an exception for this one. With its most recent set of optics, installed in May 2009 during the STS-125 servicing mission (SM4), the Hubble Space Telescope is returning amazingly detailed images of distant, exotic objects – like the butterfly-shaped planetary nebula NGC 6302,…
