Video of Cassini's Hyperion flyby

December 4, 2010 | By

Yesterday, I posted some beautiful still images from the Cassini spacecraft’s flyby of Hyperion, a weird moon of Saturn. To research the images I posted (mostly to find out how far Cassini was from Hyperion when the images were taken), I went to the Cassini raw image archive, and saw dozens of such images. My […]

I’m an astronomer, not a geomorphologist. No, I didn’t make that word up (though I thought I did before checking Wikipedia). A geomorphologist studies the structures of landforms and tries to figure out how they got that way. I guess I do that professionally for some objects (planetary nebula, supernova remnants, and esoteric stuff like […]

Saturn, surreally

May 23, 2012 | By

Take 7+ years of Saturn observations by the Cassini spacecraft, stitch a whole lot of them together into short, film-noir-like segments, and add a Beethoven soundtrack. What do you get? Awesomeness. The video was put together by Nahum Chazarra, who says on Twitter he’s a "Geology student, science lover". There’s literally too much in this […]

Mesmerizing time lapse of Saturn and Jupiter from spacecraft

April 30, 2012 | By

One of the single greatest advantages of the modern age of astronomy, in my opinion, is that digital images from telescopes and spacecraft — and telescopes on spacecraft — have been placed in the hands of everyone. It can take years of training to correctly process and interpret astronomical data, but even without that these […]

Where in the Universe is Castalia Macula?

April 29, 2012 | By

Hey! Did you know there’s a mountain range on Mercury called Caloris Montes? Didja? Or a large depression on Europa called Castalia Macula, which is oddly dark and red? Or a long, steep-sided ditch called Baba-Jaga Chasma on Venus? Or a chaotic region on Mars called, awesomely, Chryse Chaos? Well, I do, now that I’ve […]

An icy Titanic encounter

November 8, 2011 | By

This morning, I wrote about some pictures of Saturn’s moon Enceladus I found rummaging through NASA’s Cassini raw images archive. Enceladus is a small icy moon that may have an ocean of liquid water under its surface. It’s a fascinating world, and is one of those objects that cannot seem to take a bad picture; […]

The solar system's weirdest moon

November 2, 2011 | By

Our solar system is a fantastically bizarre place. There are worlds as varied as our imagination can grasp — in fact, they exhibit features we never imagined before we saw them up close. Storms larger than planets, moons with undersurface oceans, lakes of methane, worldlets that occasionally swap places… … and that’s just at Saturn. […]

Cassini visits a foamy moon

August 26, 2011 | By

I’ve said it before: Saturn’s moon Hyperion is seriously freaky. New images from the Cassini spacecraft flyby of the tiny moon don’t change my mind one bit: [Click to enchronosenate.] What a weird place! Hyperion is a lumpy chunk of ice only about 270 km (170 miles) across on average, but yesterday (August 25, 2011) […]

The stark beauty of Cassini's Saturn

June 2, 2011 | By

Speaking of Cassini… The spacecraft has been orbiting Saturn for nearly 7 years now, and has returned many thousands of images of the rings, moons, and planet back to Earth. Many times, the images are part of a series — tracking the large moon Titan, for example, or following one of the outer, faint rings […]

Raw hypermoon

December 3, 2010 | By

Stop me if you’ve heard this from me before, but Saturn and its moons are weird. Take Hyperion. 300 km across (180 miles), yet only half as dense as water! Even normal ice is denser than that, so something weird is going on there. It’s most likely that it’s full of holes, like a loosely […]
