Dear Jupiter: Use More Sunscreen

It's the signature accessory of the largest planet in our solar system: Jupiter's Great Red Spot, an enormous anticyclone¬over twice the width of our entire planet. Visible in even modest backyard telescopes, the GRS has been churning away for¬at least several hundred years. But, based on recent analysis of data gathered by the Cassini spacecraft […]

Sunburn on Jupiter?

New research on the Great Red Spot of Jupiter based on Cassini's flyby nearly 14 years ago (Dec 2000) suggests the red color is from the “sunburn” of particles and the variable color comes from cloud altitudes. From NASA: The … Continue reading →

Cassini plumbs the depths and new mysteries of Titan's seas

The Cassini spacecraft continues to make new discoveries about Titan's methane seas and lakes, answering some questions but raising additional ones as well. As announced this week, Cassini has discovered two more of the unusual magic islands – bright features which seem to appear in the seas where they didn't exist before – and has … Continue Reading →The post Cassini plumbs the depths and new mysteries of Titan's seas appeared first on The Meridiani Journal.

Comet Landing: Side-By-Side Pics Of Alien Surfaces Humanity Explored

Correction, 11:33 a. m. EST: The University of Central Florida's Phil Metzger points out that the image composition leaves out Eros, which NEAR Shoemaker landed on in 2001. This article has been corrected to reflect that and to clarify that the surfaces pictured were from “soft” landings. And now there are eight. With Philae's incredible landing […]

Jupiter's Great Red Spot Gets Its Color From Sunlight, Study Suggests

If it weren't for the Sun, Jupiter's Great Red Spot would be a much blander feature on the gas giant, a new study reveals. This stands apart from what most scientists think about why for why the spot looks so colorful: that there are features in the clouds that give it its distinctive shade. The […]

Saturn and Titan Show Off Their Crescents

It may not be in color but that doesn't make it any less beautiful: this stunning image from Cassini shows Saturn and its largest moon Titan — the second-largest moon in our solar system, after Jupiter's Ganymede — from their night sides, both showing their¬crescents against the blackness of space. Titan's crescent nearly wraps all […]

Titan’s seas and lakes sparkle in the sunlight in recent Cassini images

Saturn's moon Titan is a very unique world, and the only place in the solar system known to have seas and lakes (liquid methane/ethane) on its surface, other than Earth. And just like our home world, if you look at them at the right moment from space, you can see sunlight gleaming off of them, … Continue Reading →The post Titan's seas and lakes sparkle in the sunlight in recent Cassini images appeared first on The Meridiani Journal.

Dione – A Global View

NASA has produced global mosaics of Saturn's moon Dione from Cassini spacecraft images. The image here is a trailing hemisphere which is darker than the leading hemisphere possibly because to “alteration by magnetospheric particles and radiation striking those surfaces”. It … Continue reading →

A Dark Saturn

... look at a dark Saturn and Titan in this Cassini image. This view is looking pretty much towards the Sun providing a look at the atmosphere of Titan and a very nice crescent on both. These observations can tell … Continue reading →

Titanic Liquid: Blinding Sunglint' Shines On Saturn's Swampy Moon

See that yellow smudge in the image above? That's what the Sun looks like reflecting off the seas of Titan, that moon of Saturn that excites astrobiologists because its chemistry resembles what early Earth could have looked like. This image represents the first time this “sunglint” and Titan's northern polar seas have been captured in […]

Cassini Spots the Sun Shining on Titan’s Sea

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 Probe Spots Methane Ice Crystals In Titan's Atmosphere

During it's 2006 flyby of Titan, the Cassini Space Probe captured some of the most detailed images of Saturn's largest moon. Amongst them was one showing the lofty cloud formations over Titan's north pole (shown above). Interestingly enough, these cloud formations bear a strong resemblance to those that are seen in Earth's own polar stratosphere. […]

100,000 Ice Blocks Mapped Out at the South Pole of Enceladus

Ever since the Cassini space probe conducted its first flyby of Enceladus in 2005, the strange Saturnian moon has provided us with a treasure trove of images and scientific wonders. These include the jets of icy water vapor periodically bursting from its south pole, the possibility of an interior ocean – which may even harbor […]

Why Watch ESA Rosetta's Movie Ambition'? Because We Want to Know What is Possible

NASA has taken on space missions that have taken years to reach their destination; they have more than a dozen ongoing missions throughout the Solar System and have been to comets as well. So why pay any attention to the European Space Agency's comet mission Rosetta and their new short film, “Ambition”? ‘Ambition' might accomplish […]
