Just to remind you that things are still indeed going “boom” in our Solar System, here is a cluster of fresh craters on Mars created by an impact that occurred sometime between 2008 and 2014. The craters are a result of a meteorite that broke apart during entry, striking the surface as fragments within a localized area….

Yes, Obi-Wan, That’s a Moon
Saturn’s 250-mile-wide icy moon Mimas shines in direct sunlight and reflected light from Saturn in this image, a composite of raw images acquired by NASA’s Cassini spacecraft on Jan. 30, 2017 and received on Earth today, Feb. 1. This is a bit of a “Frankenstein” job I made, assembled from five separate narrow-angle camera images taken in…
Solar Storms Set Off Tiny Explosions In Shadowed Lunar Soil
Powerful solar storms can charge up the soil in frigid, permanently shadowed regions near the lunar poles, and may possibly produce “sparks” that could vaporize and melt the soil—perhaps as much as meteoroid impacts, according to new NASA-funded research. Read the rest of this article from NASA here: Solar Storms Could Spark Lunar Soil
It’s Been 50 Years Since We First Got Pictures From the Moon
What a difference half a century makes! This week marks 50 years since the Soviet Luna 9 spacecraft made humanity’s first-ever soft landing on the surface of the Moon. Launched from Baikonur on Jan. 31, 1966, the Luna 9 lander touched down within Oceanus Procellarum at 18:44:52 UTC on Feb. 3. Over the following three days Luna 9 sent us our first views of…
Soar Over the Surface of Tethys with Cassini
On Nov. 11, 2015, NASA’s Cassini spacecraft passed relatively closely by Saturn’s moon Tethys, one of the ringed planet’s larger icy satellites. The animation above was made from 29 raw images acquired with Cassini’s narrow-angle camera as it passed by; you can see part of the incredibly cratered and ancient surface of this 662 mile (1,065 km) wide…
Pluto: Prelude to a Flyby
This is Pluto, imaged by New Horizons’ LORRI camera on July 12. It’s (once again) the best view yet, captured from a distance of 2.5 million km / 1.5 million miles. Check out all that geology – craters, depressions, chaos terrain of some sort… at no time in human history has anyone ever seen this world in…
A Northern View of Saturn’s Stained Moon Iapetus
Here’s a raw image of Saturn’s moon Iapetus, looking down on its northern hemisphere from Cassini on March 31, 2015. The moon’s signature two-toned coloration is evident as its bright icy surface is partially coated by dark material, thought to have been ejected from distant neighbor Phoebe. Iapetus is 914 miles (1,471 km) in diameter, or…
When a Comet Met Ganymede
Captured by NASA’s Galileo spacecraft on April 5, 1997, this image shows Enki Catena, a 161.3-km (100-mile) long crater chain on the surface of Jupiter’s moon Ganymede. Named after the Sumerian god of fresh water, Enki Catena is thought to have been formed when a comet approached too close to Jupiter and was torn into 13 pieces, each impacting Ganymede in…
Where Are All of Earth’s Impact Craters?
When you look up at the Moon through a telescope or pair of binoculars you see a world covered in craters of all sizes. It only stands to reason that Earth must also have craters like the Moon, if not many more because of its much larger size. So where are they all? As it…
Here’s Your Chance to Name a Crater on Mercury!
On March 18, 2011, MESSENGER became the first human-made spacecraft to enter orbit around Mercury. Now almost four years, eight billion miles, and over 260,000 images later, MESSENGER is nearing the end of its operational life. To commemorate the many achievements of the mission, scientists from NASA and the MESSENGER teams at the Johns Hopkins…
MESSENGER Gets Up Close and Personal With Mercury
Mercury’s ready for its close-up, Mr. MESSENGER! At an incredible 5 meters per pixel, the image above is one of the highest-resolution images of Mercury’s surface ever captured. It was acquired on March 15 with the MESSENGER spacecraft’s MDIS (Mercury Dual Imaging System) instrument and shows an 8.3-km (5.2-mile) -wide section of the planet’s north polar region, speckled…
On the Lunatic Fringe: LADEE’s First Pictures of the Moon
It’s getting so a spacecraft can’t take a decent picture these days without SOMEONE getting in the way! (*Ahem* MOON.) But then it just might be the lunatic we’re looking for… The image above is one of five that were downlinked by NASA’s Lunar Atmospheric Dust Environment Explorer — aka LADEE (that’s “laddie” à la…
