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 […]

Titan's Atmosphere Still Baffles Us A Decade After Huygens Landing

It's almost exactly 10 years ago that humanity parachuted a spacecraft into Titan, that moon of Saturn that could hold chemistry similar to what sat on Earth before life arose. Called Huygens, the probe survived for just about an hour on the surface on Jan. 14, 2005, transmitting information back about conditions there and on […]

Shooting Color in the Blackness of Space

If NASA is so advanced, why are their pictures in black and white? It's a question that I've heard, in one form or another, for almost as long as I've been talking with the public about space. And, to be fair, it's not a terrible inquiry. After all, the smartphone in my pocket can shoot […]

Enceladus

... nice image of the moon Enceladus seen with the back drop of the planet Saturn. This is the same sort of alignment Cassini was in to get the image of Tethys and Mimas posted here a last week (see … Continue reading →

Ring Shadows

The Cassini – Saturn – Sun angles were just right for Cassini to capture this unusual picture. The rings of Saturn are edge on and their shadows are projected onto the planet. From the NASA caption: This view looks toward … Continue reading →

Saturn Swirls

Originally meant to publish yesterday: Cassini took this image of the Saturn swirling atmosphere. Planetary atmospheres (including our own) are a study in fluid dynamics and that is clearly evident here. The image was taken on 23 August 2014 in … Continue reading →
