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

Leigh Fletcher • February 01, 2013

That amazing image of Saturn's north pole just got better: now, it moves!

Emily Lakdawalla • November 28, 2012

Remember the amazing photo of Saturn's north pole that I posted yesterday? Now, thanks to an amateur image processor, it moves, and the motions of the individual clouds within the belts are mesmerizing.

Staring into Saturn's baleful eye

Emily Lakdawalla • November 27, 2012

Amazing photos have just come back from Cassini, of swirling clouds surrounding Saturn's north pole.

Happy Cassini PDS Release Day!

Emily Lakdawalla • October 08, 2012

It's a quarterly feast day for me: the day that the Cassini mission delivers three months' worth of data to NASA's Planetary Data System. Here's a few images processed from the October 1, 2012 data release.

A couple of gems from the archives

Emily Lakdawalla • September 10, 2012

We're still working on migrating content from the old to the new website. This week, that means I am looking, one by one, through some great amateur-processed space images.

Saturn's still there

Video: Saturn makes its own drama (with a little help)

Emily Lakdawalla • May 22, 2012

The apparently simple device of running Cassini images together like a flipbook makes for a dramatic movie, especially with the help of well-timed musical cues.

Pretty pictures from Cassini's recent Dione flyby

Emily Lakdawalla • May 04, 2012

Cassini performed its last of three close encounters with Enceladus for 2012 two days ago, and followed the flyby with some spectacular images of Dione.

Pretty picture: A study in ringlight

Emily Lakdawalla • March 08, 2012

Clearly, this is Saturn, and its rings, and if you look closer you can see a tiny circle, on top of the rings, which is Mimas, and two stars in the background. It should look weird to you that while the rings are bright, Mimas is a black dot. What is happening here? Nearly everything in this picture is lit by light that has not arrived directly from the Sun.

Checking up on Jupiter and Saturn

Emily Lakdawalla • February 10, 2012

It's amateur astronomers, not professionals, who are shouldering the burden of constant monitoring of the weather on Jupiter and Saturn. What's going on these days in the outer solar system?

Pretty picture: Saturn, a big moon, and a teeny one

Emily Lakdawalla • January 09, 2012

A recent view from Cassini of Saturn with its largest moon (Titan) and one of its small ringmoons, Prometheus.

Pretty pictures & movies: Eye candy from two recent Cassini Enceladus flybys

Emily Lakdawalla • October 20, 2011

Cassini has completed two very close flybys of Enceladus in less than three weeks, one of them just this morning, and the images from that encounter have already arrived on Earth.
