Through a Glass, Darkly

Bill Dunford • January 13, 2014

When sent from deep space, even imperfect images can inform and amaze.

Polar vortices across the solar system

Emily Lakdawalla • January 09, 2014

Earth's polar vortex has been in the American news all week. But we're not the only planet that has one; basically every world that has an atmosphere has a polar vortex. Here are lots of pretty pictures and animations of polar vortices.

Cosmos with Cosmos Episode 6: Travellers' Tales

Casey Dreier • November 25, 2013

The Voyager mission may be the ultimate expression of our desire to explore, but why does that will exist in the first place? Why is it unique to humans?

Just what is going on in that magnificent Cassini image of Saturn?

Emily Lakdawalla • November 13, 2013

It took months of work (and no wonder) but the wait was worth it: here is Cassini's spectacular view of Saturn, captured on July 19, 2013, as Cassini passed through Saturn's shadow. If you're a little confused by the image, I'm here to help: I've posted a video explainer.

Will We Lose Cassini’s "New" Mission at Saturn to Budget Cuts?

Van Kane • November 12, 2013

NASA’s shrinking budgets for planetary exploration may force it to decide between continued funding for the Saturn Cassini mission and the continued funding for its Mars missions.

One for the history books: Stunning Saturn mosaic captured last week by Cassini

Emily Lakdawalla • October 16, 2013

I try to be measured in my praise for spacecraft images. Not every photo can be the greatest space image ever. But this enormous mosaic showing the flattened globe of Saturn floating within the complete disk of its rings must surely be counted among the great images of the Cassini mission.

Gravity assist

David Shortt • September 27, 2013

With the recent announcement by NASA that the 36 year-old spacecraft Voyager 1 has officially entered interstellar space at a distance from the sun about four times further than Neptune's orbit, and with Voyager 2 not far behind, it seems worthwhile to explore how humans managed to fling objects so far into space.

Europe Will Select Its Next Major Science Mission in November

Van Kane • September 25, 2013

The European Space Agency will announce two major science missions this November, one of which is likely to be devoted to solar system exploration.

Pretty picture: spectacular Saturn and Titan

Emily Lakdawalla • August 15, 2013

A lovely view of the ringed planet and its hazy moon seen from nearly behind them just a few days ago.

Pretty picture: Looking backward

Emily Lakdawalla • July 23, 2013

Here it is: the view from Saturn of our Earthly home, one and a half billion kilometers away. We see Earth and the Moon through a thin veil of faintly blue ice crystals, the outskirts of Saturn's E ring. Earth is just a bright dot -- a bit brighter than the other stars in the image, but no brighter than any planet (like Saturn!) in our own sky.

Return of the Pale Blue Dot

Mat Kaplan • July 18, 2013

You can be part of a planetwide group photo as Cassini and MESSENGER turn their cameras Earthward on July 19.

The Space Computer and the Beautiful Worlds

An "Up Goer 5" tribute to the Cassini mission.

One of my favorite image processing tricks: colorizing images

Emily Lakdawalla • April 23, 2013

An easy image processing trick -- using lower-resolution color data to colorize a black-and-white photo -- is relied upon by many space missions to keep data volumes low. Here's how to do it.

In a New Light

Bill Dunford • April 15, 2013

Cassini's unique views of Jupiter and Saturn.
