ESA Grabs Glimpses of Mars’ Groovy Moon

This animation is comprised of three images acquired by ESA’s Mars Express spacecraft on Sept. 12, 2017 with its High Resolution Stereo Camera (HRSC). It shows parts of the grooved and pitted surface of Phobos, the larger of Mars’ two natural satellites. The original images were captured in greyscale; I added color based on other…

Asteroid 2014 JO25 Gets Some Sweet Radar Love

This is our best look yet at asteroid 2014 JO25, which made its closest pass by Earth for at least the next 500 years on April 19, 2017. The animation above is composed of radar observations made from NASA’s Goldstone facility in California when the asteroid was between 1.53 and 1.61 million miles away. These…

Opportunity Spots Phobos Skimming the Sun

It may be in its 14th year on Mars but Opportunity still has some surprises to show us—like this, a series of images captured on May 3, 2017 showing the Sun as seen from Mars. But that’s not the special part: see the change in brightness along the Sun’s edge near the end? That was a…

A Departing View From Cassini After Clearing the Gap

Cassini did it again! On May 2-3, 2017 the spacecraft made its second “ring dive” pass of Saturn, passing through the clear space between the innermost edge of the ring system and the planet itself. The animation above shows a view from Cassini looking back toward Saturn on its outbound flight on May 3, just a…

Cute Science Video Alert: The Story of Stars

Like people, stars are found in all colors and sizes. They can range from small, sassy red dwarfs to giant blue beasts. In fact there are seven main types of stars, grouped by their apparent colors (and thus temperatures) and classified as O, B, A, F, G, K, or M in order of hottest to coolest. (Learn more about…

Curiosity’s Tracks Are Gone With The Wind

Mars may have an atmosphere just 1% the density of Earth’s but it can still stir up enough of a breeze to quickly cover a rover’s tracks, as evidenced in the animation above. Captured by Curiosity’s downward-looking Mars Descent Imager (MARDI) camera on Jan. 23 and 24, 2017, the two pictures show an approximately 3-foot-wide…

An Asteroid Approaches Your Planet: Roll a d10

It sounds like a surprise challenge posed by the “Dungeon Master” in a game of Dungeons & Dragons but this is sort of what happened on a cosmic scale on Feb. 6, 2017, when the 200-meter (656-foot) -wide asteroid 2017 BQ6 passed by Earth. Using the radar imaging capabilities of the giant 70-meter antenna at…

Death in Space

Here’s a bit of fun for you: an animated short of ways one could meet one’s end on a space adventure, by professional animator and illustrator Tom Lucas. Obviously this is more science-fiction than science fact, what with the hungry aliens and all, but you still wouldn’t want to smash yourself in the faceplate with a chunk…

This is What it Would Look Like to Fight Flying Dragons on Titan

Obviously this is a totally-for-fun sci-fi video, but what a video! Created by Oscar-nominated Irish filmmaker Ruairi Robinson, it shows fleets of very industrial-looking fighter skiffs hunting giant flying eels through the skies of some very cloudy planet… the first thought that came to my mind was Titan! (Although Titan is more hazy than cloudy…
