It may look like a scene from the US southwest but it’s actually somewhere much, much farther away… 206.3 million miles away, to be exact — it’s a view from the Curiosity rover looking toward the center of Gale Crater, where the informally-named Mount Sharp rises up 3.4 miles from the crater floor.

Ghosts of Worlds Passed
Saturn’s F ring is a fascinating structure. Made of fine icy particles — most no larger than the particulates found in cigarette smoke — it orbits Saturn just outside the A ring and is easily perturbed by the gravity of nearby moons and embedded moonlets, which create streamers and clumps that rise up in fanciful…
Cassini’s Christmas Gift: a Peek at Prometheus
Captured on Christmas Day, this is a raw image from Cassini showing Saturn’s F ring buckling inwards at two places due to the gravitational tug of its inner shepherd moon, Prometheus, seen at center. As the irregularly-shaped moon approaches the ring material in its looping orbit around Saturn it draws material from the ring in…
A Colorful Christmas Moon
Merry Christmas and happy holidays everyone! Here’s your present from Lights in the Dark: a color-composite of Saturn’s moon Dione, lovingly made from raw images captured by the Cassini spacecraft on December 23. 700 miles (1120 km) wide, Dione (pronounced DEE-oh-nee) is covered pole-to-pole in craters and is crisscrossed by deep chasms and long, bright…
Book Review: The Star Book
If you’re still looking for that last-minute gift for the astronomy fan in your life (and let’s be honest; that may very well be yourself — I won’t tell) may I suggest this little gem: The Star Book: How to Understand Astronomy published by David & Charles. The latest book by amateur astronomer and astrophotographer…
Saturn’s Backlit Beauty
As a sort of Christmas gift to the world, the Cassini mission team released this image today, a majestic mosaic showing the planet Saturn gleaming in backlit sunlight. “Of all the many glorious images we on Cassini have received from Saturn, none are more strikingly unusual than those we have taken from within Saturn’s shadow,”…
Heeeeeey, NASA Ladies!
NASAÂ Gagnam Johnson style! Give these kids an automatic “A”.
On the Death of my Dad
Yesterday I buried my father. To be exact, yesterday was the funeral for my father. It was with military honors, as he served four years in the Navy during the Vietnam War, mostly aboard the heavy cruiser U.S.S. Newport News. Family and friends were in attendance, my younger brother as well as his older and…
A River Runs Through It (and when I say “It” I mean Saturn’s moon Titan)
No, you’re not looking down at the Amazon or the Nile (although the confusion would be understandable)… this is actually a river on an entirely different world: Saturn’s moon Titan! Radar imaging by NASA’s Cassini spacecraft has revealed what appears to be a long river system, complete with side-branching tributaries, meandering across the surface of…
Our Electric Earth at Night: the “Black Marble”
In daylight our big blue marble is all land, oceans and clouds. But the night is electric. This image of North and South America at night is a composite assembled from data acquired by the Suomi NPP satellite in April and October 2012. The new data was mapped over existing Blue Marble imagery of Earth to provide a realistic…
Hidden Ice Found on Mercury!
Who says Mercury’s too hot to be really cool? Even three times closer to the Sun than we are, lacking atmosphere and with scorching daytime temperatures of 425 ºC (800 ºF), Mercury still has places more than cold enough to hide ice. This is the most recent announcement from the MESSENGER mission team: (very nearly) confirmed…
Curiosity Has So Many Cool Things to Find
Water, methane, organic compounds, Twinkies, Amelia Earhart’s plane… there’s just so many cool things for Curiosity to find on Mars! This little production by Seattle-based Cinesaurus may be a parody of “Dumb Ways to Die” but there’s certainly nothing dumb about the exciting things that Curiosity’s already found in its brief time in Gale Crater……
