There’s nothing like the beautiful reflection of sunlight off the mirrored surface of a lovely lake… regardless if you’re on Earth or Saturn’s moon Titan! This picture, a mosaic of images acquired by Cassini’s Visual Infrared and Mapping Spectrometer (VIMS) instrument during a flyby on August 21, 2014, shows exactly that: sunglint reflecting off the super-smooth…

Cassini Watches Clouds Form Over Titan’s Methane Sea
What’s the weather forecast on Titan? Well if you’re planning a vacation down by the shores of Ligeia Mare you may get some cloudy skies, if what happened at the end of July repeats itself! The animation above was made from images acquired by Cassini during a flyby of Titan in July 2014, showing the…
Cassini Marks Ten Discovery-Filled Years at Saturn
Just a week after Curiosity celebrated its first Martian year in Gale Crater and we have yet another milestone anniversary in Solar System exploration: as of 10:48 p.m. EDT tonight Cassini will have been in orbit around Saturn for a full decade! “There are times when human language is inadequate, when emotions choke the mind, when the magnitude…
What’s Ahead for Cassini?
If you’ve been a faithful reader of Lights in the Dark over the past five years you know that I just love Cassini (and you probably do too!) In orbit around Saturn since 2004, Cassini has taken us on an intimate tour of the Saturnian system for a decade now, revealing the incredible beauty of the…
This is How Saturn’s Rings Would Look to a Butterfly
You don’t typically see Saturn’s rings looking like this, but then you can’t see in ultraviolet like Cassini (or many insects) can! The image above was acquired by the UVIS (UltraViolet Imaging Spectrograph) instrument aboard the Cassini-Huygens spacecraft on June 30, 2004, just as it was entering orbit around Saturn. The area shown here is…
Saturn’s Still in the Business of Making Moons
Congratulations! It’s a baby… moon? A bright clump spotted orbiting Saturn at the outermost edge of its A ring may be a brand new moon in the process of being born, according to research recently published in the journal Icarus. “We have not seen anything like this before,” said Carl Murray of Queen Mary University…
Just Another Hazy Day on Titan
The weather forecast for Titan? Cloudy, hazy, and cold — just like every other day! The image here is a color-composite made from raw data captured by Cassini during a flyby on April 7, 2014, and it shows a look at the two main features of Titan’s atmosphere: a thick orange “smog” made of organic…
Cassini Uncovers Even More Evidence for Enceladus’ Hidden Ocean
It’s been suspected for nearly a decade that Saturn’s 315-mile-wide moon Enceladus harbors a hidden ocean beneath its frozen crust, thanks to observations by the Cassini spacecraft of icy plumes spraying from its southern pole, and now scientists have even more evidence supporting its existence: Doppler measurements of the moon’s gravity taken during Cassini’s flybys show variations…
Have Waves Finally Been Found on Titan’s Lakes?
We’ve known for quite some time now that lakes of liquid methane and ethane exist on the frigid surface of Saturn’s overcast moon Titan. While the sheer presence of large amounts of liquid on another world is fascinating, one thing that’s particularly intrigued scientists about these hydrocarbon lakes is their uncanny stillness — in many…
A Visual Demonstration of Gravity, Courtesy of Cassini
Prometheus is at it again! On Feb. 5, Cassini acquired a series of images with its narrow-angle camera of Saturn’s reflective and ropy F ring, around the inside of which travels the shepherd moon Prometheus. As it orbits Saturn it regularly arcs outwards toward the inner edge of the F ring and tumbles back inwards…
The Brightest Lights: 12 Awesome Space Stories of 2013
What a year for space exploration! With 2013 coming to a close I thought I would look back on some of the biggest news in space that I’ve featured here on Lights in the Dark. Rather than a “top ten” list, as is common with these year-end reviews, I’m going to do more of a…
Celebrate the Holidays with Cassini and Saturn
Cassini couldn’t make it to the mall this year to do any Christmas shopping but that’s ok: we all got something better in our stockings than anything store-bought! To celebrate the holidays the Cassini team has shared some truly incredible images of Saturn and some of its many moons for the world to “ooh” and “ahh”…
