Heather Hunter brings us the next installment in her series on radio detection and ranging.

Heather Hunter explains how radar works and what it's used for on Earth and beyond.

For the third time in less than a decade, scientists have proposed a multiple-flyby mission to explore the habitability of Saturn’s ocean moons Titan and Enceladus.

Titan's north polar lakes are well-lit by summer sun in these recent Cassini images. Image processing enthusiast Ian Regan shares his recipe for processing the longer-wavelength Titan images into visually pleasing

Why do we need to slice up atmospheres into classifications like the troposphere, stratosphere, mesosphere, and thermosphere?

There are two types of atmospheric waves that are critically important on Earth and other planets: gravity waves and planetary waves.

Huygens may have landed on Titan over a decade ago, but a group of researchers from York University were able to make a new and unexpected discovery with this older dataset.

What types of aerosols do we find in the atmospheres around the Solar System, and why does what we call them—clouds vs. haze vs. dust—matter? Sarah Hörst explains.

Image processing enthusiast Ian Regan produced a pretty view of Titan's lake-filled north pole, now visible to Cassini's cameras in the summer sun.

Tomorrow, Cassini will fly by Titan, picking up a gravity assist that will tilt its orbit slightly up and out of the ring plane. That will end what has been a wonderful year of frequent encounters with Saturnian moons.

I don't think anyone was prepared for the beauty -- or the instant scientific discoveries -- in this

I checked out the latest public image release from Cassini and found an awesome panorama across Saturn's rings, as well as some pretty views looking over Titan's north pole.

Now that Cassini has returned to Saturn's equatorial plane, it has lots of opportunities to observe Saturn's moons. For about a week, Cassini has been taking regular sets of images of Iapetus, which I've assembled into an animation.

Planetary scientist Nathan Bridges reports on results from the Lunar and Planetary Science Conference about the action of wind on the surfaces of Mars and Titan.

The landing of Huygens on Titan was a significant moment for planetary science and a great accomplishment for Europe. But the Huygens landing also stimulated the development of the international community of amateur image processors that does such great work with space images today. I was in the midst of it all at the European Space Operations Centre in Darmstadt.

The 45th Binghamton Geomorphology Symposium, usually focused on terrestrial studies, shifted this year to planetary science. Ted Stryk gives us an overview.

Last year, rumors swirled that NASA may be so pinched for dollars that the agency might end the Cassini mission early. Today, Cassini received the welcome news that it has formally been funded through the planned end of its extended-extended mission in 2017. A huge congratulations to the Cassini mission!

In December, scientists announced the discovery of possible plumes of water being ejected from Jupiters’s moon Europa. If confirmed, Europa would be the second moon with confirmed plumes after Saturn’s moon Enceladus. Two Discovery mission proposals for Enceladus suggest the types of missions that may be proposed for Europa.
