According to research by NASA astronomers using the next-generation optics of the 10-meter Keck II telescope, Jupiter’s ice-encrusted moon Europa has hydrogen peroxide (aka H2O2) across much of the surface of its leading hemisphere, a compound that could potentially provide energy for life if it has found its way into the moon’s subsurface ocean. “Europa has the…

The Colors of Saturn’s Northern Skies
Bored by blue? Saturn’s skies sure do have a lot more colors, as seen here in a color-somposite made from raw Cassini images acquired on Feb. 27, 2013. With spring progressing on Saturn’s northern hemisphere (a season that takes 7 1/2 Earth years to pass!) the upper latitudes gradually receive more sunlight and thus more…
Vote to Name Pluto’s Moons!
I’ve written about this a couple of times before and put up polls here on Lights in the Dark, but now it’s actually semi-official: you can vote on the names for Pluto’s newest moons! (Looks like they may have taken some of our earlier suggestions too!)
A Martian Panorama
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.
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…
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,”…
Our Sharpest (Ground-Based) View of Pluto Yet:
Real planet, dwarf planet, KBO… who cares? What matters here is that astronomers from NASA, NOAO and the Gemini Observatory have created the sharpest image of Pluto ever made with ground-based observations — and developed a new way to verify potential Earth-like exoplanets at the same time. Not too shabby, I’d say. Here’s how they…
Dawn Makes an Elemental Discovery on Vesta
In what could be called a “eureka” moment for Dawn researchers and planetary scientists alike, hydrogen has been found on the surface of Vesta, a 550-km (340-mile) -wide protoplanet and the second most massive world in our Solar System’s main asteroid belt. The elemental discovery was made with the Gamma Ray and Neutron Detector (GRaND)…
Once you realize what this Cassini image is showing, you’ll love it.
Go ahead, take a look. Let it sink in…..waaaait for it…… there. I told you. Still wondering what it is you’re looking at? That’s ok, you’ll love it even after I tell you.
What We’ve Learned From The Kuiper Belt
Today marks the 20th anniversary of the discovery of the first Kuiper Belt Object, 1992QB1. Called KBOs for short, these are distant and mostly tiny worlds made up of ice and rock that orbit the Sun at incredible distances, yet are still very much members of our Solar System. Since 1992 over 1,300 KBOs have been found,…
Voyager’s Visit to Uranus
Voyager 2 may have been the second of NASA’s twin exploration spacecraft but it launched first, 35 years ago today on August 20, 1977. 8 1/2 years later it became the first (and last!) spacecraft to visit the gas giant Uranus, the third largest planet in the Solar System.
A Lomographic Look at Mount Sharp
Looking like an old photograph of a Western U.S. landscape, this is a view from Curiosity’s acquired on August 18 (UTC) with the rover’s right Navcam. I colored the image using some of Curiosity’s previous color shots for reference, and adjusted the curves quite a bit from the original to bring out some contrast. The…
