Cassini Has Just Taken the Best Picture of Daphnis Yet!

Hello, Daphnis! On January 16, 2017, the Cassini spacecraft captured the best photo yet of Daphnis, a 5-mile-wide shepherd moon that orbits Saturn inside the Keeler Gap at the outermost edge of the A ring (and also just so happens to be my personal favorite moon of Saturn!) The raw image arrived on Earth today, and…

What would it look like to watch Daphnis fly past?

Maybe something like THIS: What a great combination: Daphnis (my favorite moon) and an artist’s interpretation of what it might look like to see it whiz past as it travels around Saturn inside the Keeler Gap, sending up waves in the rings as it goes! The image is by Erik Svensson, who came across my recent…

Daphnis Is Back!

It’s been a while since I posted an image of my favorite moon of Saturn, but while looking through some recent raw images returned by the Cassini spacecraft I spotted it: Daphnis, the little sculptor shepherd moon!

Daphnis in Full Color

If you’ve been following along with Lights in the Dark since the beginning, you may know that this is one of my favorite subjects of space imagery: the shepherd moon Daphnis, traveling in its orbit around Saturn within the 26-mile-wide Keeler Gap. Recently color-calibrated by Gordan Ugarvovic, this is a true-color version of an image…

Prime PDS Picks

Every six to nine months or so the Cassini Imaging Center dumps orbiter image data into NASA’s Planetary Data System, or PDS. This data is accessible to anyone with an internet connection, but it can be a little awkward to find exactly what you’re looking for (unless you’re familiar with the technical nomenclature of the…

Ring Racer (Take Two)

I came across this image today while going through the latest Cassini PDS (Planetary Data System) release, and remembered how excited I was to see it the first time when it came in last June. If you missed it, here it is again (with an image fresh off the PDS!) Man, I just LOVE this…

From the LITD Archives: Wave Forms

(Originally posted on June 27, 2009) Cast shadows reveal some interesting structure in the waves sent up by little Daphnis in this image, taken by the Cassini spacecraft on June 26, 2009. Daphnis orbits Saturn within the 26-mile-wide Keeler gap in the A ring. Its gravity disrupts the edges of the gap, carving scalloped edges in…

Daphnis Close-up

On July 5 the Cassini spacecraft took this image of Daphnis, a 4.5-mile-wide shepherd moon that orbits Saturn within the Keeler Gap. It’s the closest image yet of Daphnis, a moon that’s famous for the scallop-edged gravitational wake it makes on the edges of the gap as it passes. Read more on the Cassini mission…

Ring Racer

Man, I just LOVE this stuff. 🙂 This has to be one of the coolest images yet of one of my favorite subjects: Saturn’s moon Daphnis casting a shadow and riling up the rings as it travels along the 26-mile-wide Keeler Gap, a channel it keeps clear around the outer edge of the A ring….
