If you’re in love with space exploration then you’ll fall for this: it’s the picture of Earth taken from the Voyager 1 spacecraft after it passed the orbit of Pluto in 1990. That image of our planet from almost 4 billion miles away inspired Carl Sagan to write his famous “Pale Blue Dot” passage, and…

Comet 67P Fires Up Its Jets
And the show is on! The dramatic images above show the actively jetting comet 67P/Churyumov-Gerasimenko on Jan. 31 and Feb. 3, imaged by Rosetta’s NavCam from a distance of about 28 km (17 miles). Each is a mosaic of four separate NavCam acquisitions, and I adjusted and tinted them in Photoshop to further enhance the jets’ visibility….
What Do Lunar Phases Look Like From the Other Side of the Moon?
We’ve all seen the Moon go through its phases over the course of a month’s time (give or take a day or two) as it travels in its orbit around the Earth, and you may have even seen the cool animation from the NASA Goddard Visualization Studio showing an entire year’s worth of lunar phases….
Dawn Captures the Bestest Images Ever of “Hipster Planet” Ceres
This is the second animation from Dawn this year showing Ceres rotating, and at 43 pixels across the images are officially the best ever obtained! NASA’s Dawn spacecraft is now on final approach to the 590-mile-wide dwarf planet Ceres, the largest world in the main asteroid belt and the biggest object in the inner Solar System that has yet to…
Opportunity Celebrates 11 Years on Mars With a Grand Panorama
While we have been getting most of our daily images of Mars from NASA’s Curiosity rover over the past couple of years, we shouldn’t forget that there’s still another rover keeping busy on the Red Planet: Opportunity, one of the twin Mars Exploration Rovers (MER-B), still exploring after 11 years! To commemorate Opportunity’s upcoming landing…
Been Waiting for Hi-Res OSIRIS Images of Rosetta’s Comet? Here They Are!
Many of the images we have been seeing of Rosetta’s comet – 67P/Churyumov-Gerasimenko, or 67P for short – have been captured with the spacecraft’s NavCam instrument. And while they have been amazingly beautiful in their own right, NavCam isn’t Rosetta’s best camera; that distinction goes to OSIRIS, the Optical, Spectroscopic, and Infrared Remote Imaging System…
Hello, Ceres! Dawn Returns Images of Dwarf Planet Spinning
Wow, check this out! The 590-mile-wide dwarf planet Ceres is seen rotating in this GIF animation made from the latest images from NASA’s Dawn spacecraft, taken over the course of an hour on January 13, 2015. Dawn was 238,000 miles (383,000 km) from Ceres when the images were taken, and although only 27 pixels across…
Curiosity’s First “Selfie” of 2015
Here’s a “selfie” of NASA’s Curiosity rover, made from about 20 images acquired by its MAHLI instrument on mission sol 868 (January 14, 2015). I used Photoshop to stitch the raw images together and then enhanced the contrast and detail with a bit of HDR effect. (There’s one spot behind the rover’s RTG where an…
Remembering Huygens’ Titan Landing, Ten Years Later
This incredible image was captured ten years ago today, on January 14, 2005. It shows the murky surface of Saturn’s moon Titan as seen by the European Space Agency’s Huygens probe after it made its historic descent through the moon’s thick haze and clouds and landed in a frozen plain of crusty methane mud and icy pebbles….
Eppur Si Muove: Galileo’s Big Night
Note: This is an edited repost of an article from 2014. 405 years ago tonight, January 7, 1610, the Pisan astronomer Galileo Galilei looked up at a bright Jupiter at opposition through his handmade telescope and saw three little “stars” next to it, which piqued his natural scientific curiosity. He soon realized that these little…
Hubble’s Stunning Star-Filled View of the Andromeda Galaxy
It’s Hubble’s 25th anniversary in space this year but it seems like we’re the ones getting all the presents! Yesterday NASA released two new high-def versions of the famous “Pillars of Creation” image, and now today there’s this: Hubble’s most detailed image ever of the Andromeda Galaxy! Containing over 100 million stars it’s not just the…
A Postcard from Mars: Salsberry Peak Panorama
Every now and then I get unexpectedly caught up in a project that I originally intended to be a quick just-for-fun thing and ends up taking an hour and a half of my time (usually long after I should have gone to bed.) This was one of those. Made up of 28 raw images acquired…
