Fun with a new image data set: Mars Orbiter Mission's Mars Colour Camera

Emily Lakdawalla • October 06, 2016

It's always a delight to sink my teeth into a new data set, and I have spent this week playing with one I've been anticipating for a long time: ISRO's Mars Orbiter's Mars Colour Camera, or MCC. MCC is unique among current Mars cameras in its ability to get color, print-quality, wide-angle, regional views of Mars.

Gaia's first galaxy map

Emily Lakdawalla • September 14, 2016

The astronomy world is abuzz today because of ESA's announcement of the first release of data from the Gaia mission. Gaia is a five-year mission that will eventually measure the positions and motions of billions of stars; this first data release includes positions for 1.1 billion of them, and proper motions for 2 million.

A deep dive into the highest-resolution Voyager Jupiter data

Björn Jónsson • September 14, 2016

A few weeks before the first Juno high resolution imaging, I decided to take a look at Voyager color images at various resolutions, with particular attention to high-resolution mosaics.

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."
