Our journalists and guest bloggers bring you stunning imagery and the space stories that matter most.

The not-planets

Emily Lakdawalla • July 14, 2015 • 38

Now that I have a reasonable-resolution global color view of Pluto, I can drop it into one of my trademark scale image montages, to show you how it fits in with the rest of the similar-sized worlds in the solar system: the major moons and the biggest asteroids.

A few gems from the latest Cassini image data release

Emily Lakdawalla • April 24, 2015 • 4

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 • 4

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.

Ceres Gets Real; Pluto Lurks

Paul Schenk • March 27, 2015

Although we are still along way from understanding this fascinating little body, Ceres is finally becoming a real planet with recognizable features! And that's kinda cool.

Four Ideas to Bust the Floor on Outer Planet Mission Costs

Van Kane • March 26, 2015 • 7

The road to lower costs outer planet missions has been paved by NASA’s first two New Frontiers missions, the $700M New Horizons mission to Pluto and the $1.1B Juno mission to Jupiter. But can the cost of a mission to the outer solar system be cut to $450M, the limit for a Discovery mission?

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.

At last, Ceres is a geological world

Emily Lakdawalla • February 25, 2015 • 25

I've been resisting all urges to speculate on what kinds of geological features are present on Ceres, until now. Finally, Dawn has gotten close enough that the pictures it has returned show geology: bright spots, flat-floored craters, and enigmatic grooves.

Cassini begins a year of icy moon encounters with a flyby of Rhea

Emily Lakdawalla • February 12, 2015 • 5

At last! Cassini is orbiting in Saturn's ring plane again. I do enjoy the dramatic photographs of Saturn's open ring system that Cassini can get from an inclined orbit, and we won't be getting those again for another year. But with an orbit close to the ring plane, Cassini can repeatedly encounter Saturn's icy moons, and icy moon flybys are my favorite thing about the Cassini mission.

Ceres Coming Into View

Paul Schenk • February 03, 2015 • 1

Dawn is on approach to Ceres, the largest of the asteroids, and is starting to resolve features.

Fountains of Water Vapor and Ice

Deepak Dhingra • January 22, 2015 • 2

Deepak Dhingra shares some of the latest research on Enceladus' geysers presented at the American Geophysical Union (AGU) Fall Meeting in San Francisco last month.
