Where Did Europa's Water Geyser Go? Hubble Double-Checking Its Work

It was about this time last year that Europa really began to excite us again. Following a sci-fi movie about the Jupiter moon, astronomers using the Hubble Space Telescope announced they had found possible water vapor near the icy moon — maybe from geysers erupting from its icy surface. (That is, if the finding was […]

Incredible Towering Structures Cast Shadows Across Saturn's Rings

From a distance, Saturn's rings look like a sheer sheet, but peer up close and you can see that impression is a mistake. Shadows from rubble believed to be two miles (3. 2 kilometers) high are throwing shadows upon the planet's B ring in this image from the Cassini spacecraft. While the picture is from 2009, […]

High Phase Geometry

Not the usual bright gem of a planet Saturn tends to be thanks to the “high phase” geometric positioning of Sun, Saturn, and Cassini in this image. From the Cassini web page: Saturn's main rings, seen here on their “lit” … Continue reading →

Gallery: Saturn Moons Show How Not To Be Seen In Cassini Images

Peekaboo! Tethys makes a (mostly in vain) attempt to hide behind Rhea in this picture taken by the Cassini spacecraft a couple of years ago, but highlighted by NASA in a recent picture essay. Besides the neat view of the orbital dance, one thing that is clearly visible between the two moons is the different […]

Moon Pairing

... very nice Cassini image of the Saturn moons Rhea and Tethys. The orientation of the pair is such that we can see what looks like large matching craters on each moon. ┬I believe the crater on Rhea (the moon … Continue reading →

Strong winds explain Titan's immense dunes, according to new study

Saturn's largest moon Titan is one of the most Earth-like places in the Solar System, as least in terms of appearances, with its seas, lakes, and rivers (of liquid methane/ethane). But it is similar in another way as well, with vast stretches of huge wind-blown dunes in its equatorial regions. Only Earth, Venus, and Mars … Continue Reading →The post Strong winds explain Titan's immense dunes, according to new study appeared first on The Meridiani Journal.

Freak Fast Winds Created Titan's Massive, Mysterious Dunes

Titan is Saturn's largest moon and is constantly surprising scientists as the Cassini spacecraft probes under its thick atmosphere. Take its dunes, for example, which are huge and pointed the wrong way. Why are they pointing opposite to the prevailing east-west winds? It happens during┬ two rare wind reversals during a single Saturn year (30 […]

Swirly Southern Picture Of Jupiter Makes Us Want To Visit Right Now

Gimme a rocketship – we want to see what those bands are made of! This is a strange view of Jupiter, a familiar gas giant that humanity has sent several spacecraft to. This particular view, taken in 2000 and highlighted on the European Space Agency website recently, shows the southern hemisphere of the mighty planet. […]

Saturn Smackdown! Icy Moons Burned By Radiation And Ions

If you hang out in Saturn's intense magnetic environment for a while, it's going to leave a mark. That's one conclusion from scientists who proudly released new maps yesterday (Dec. 9) of the planet's icy moons, showing dark blotches on the surfaces of Dione, Rhea, and Tethys. Cassini has been at Saturn for more than […]
