The Two Faces of Phoebe

Daniel Macháček • February 13, 2014

Cassini flew past Phoebe on June 11, 2004, on its way to entering Saturn orbit. The flyby was almost perfect but overexposure of some images have prevented color mosaics from being produced. Even though Phoebe's body is gray and dull in color, the absence of color images always provoked me. By using VIMS data, I have now produced color mosaics.

"Secrets of the Kuiper Belt" in Sky & Telescope

Emily Lakdawalla • January 16, 2014

Woo hoo! I've got another cover story in the current (February 2014) issue of Sky & Telescope, in which I try to make sense of the Kuiper belt. This article was motivated by my observation that the discovery of many new things beyond Neptune had, through an ironic chain of events, resulted in our teaching children less about the solar system than we used to.

On Sunday, the shadow of the Moon passed across Africa and the Atlantic Ocean. This was the last solar eclipse of the year. The Elektro-L satellite was able to observe the eclipse, and we can see the darkness of the lunar shadow covering Africa.

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.
