Radar in Earth and Planetary Science: An Intro

Heather Hunter • February 24, 2017

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

Explorer of Enceladus and Titan

Van Kane • February 01, 2017

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.

Cassini's camera views of Titan's polar lakes in summer, processed into pseudocolor

Emily Lakdawalla • September 12, 2016

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 "pseudocolor."

The what-o-sphere? An explainer

Anna Scott • May 05, 2016

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

Atmospheric Waves Awareness: An Explainer

Anna Scott • April 20, 2016

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

Fog Detection from the Surface of Titan: New Findings From Old Data

Brittney Cooper and Christina Smith and John Moores • April 07, 2016

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.

Clouds and haze and dust, oh my!

Sarah Hörst • March 24, 2016

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.

Pretty pictures: Cassini views of Titan's poles (with bonus Enceladus)

Emily Lakdawalla • February 25, 2016

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.

Pretty pictures: Bittersweet goodies from Cassini at Titan, Enceladus, and Telesto

Emily Lakdawalla • January 15, 2016

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.

Looking back at Pluto

Emily Lakdawalla • July 24, 2015

I don't think anyone was prepared for the beauty -- or the instant scientific discoveries -- in this "lookback" image of Pluto, captured by New Horizons shortly after it flew by.

A few gems from the latest Cassini image data release

Emily Lakdawalla • April 24, 2015

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.

Pretty Cassini pictures: animation of Iapetus' north pole, and other fun

Emily Lakdawalla • April 03, 2015

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.

LPSC 2015: Aeolian Processes on Mars and Titan

Nathan Bridges • March 26, 2015

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.

Ten years after the Huygens landing: The story of its images

Emily Lakdawalla • January 15, 2015

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.

Riding With Cassini Through 2014

Bill Dunford • December 31, 2014

Video: see some of the sights Cassini saw this year.

A (Difficult) Day in the Solar System

Bill Dunford • October 30, 2014

After a bad day on the launch pad, some perspective.

45th Binghamton Geomorphology Symposium Report

Ted Stryk • September 23, 2014

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

Cassini's awesomeness fully funded through mission's dramatic end in 2017

Emily Lakdawalla • September 03, 2014

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!
