13 Jun 2014 NASA Experiments Recreate Aromatic Flavors of Titan
NASA scientists have created a new recipe that captures key flavors of the brownish-orange atmosphere around Saturn's largest moon, Titan. The recipe is used for lab experiments designed to simulate Titan's chemistry. With this approach, the team was able to classify a previously unidentified material discovered by NASA's Cassini spacecraft in the moon's smoggy haze.
15 May 2014 The shrinking of Jupiter's Great Red Spot
Jupiter's trademark Great Red Spot -- a swirling storm feature larger than Earth -- is shrinking. This downsizing, which is changing the shape of the spot from an oval into a circle, has been known about since the 1930s, but now these striking new NASA/ESA Hubble Space Telescope images capture the spot at a smaller size than ever before.

4 Dec 2013 NASA's Cassini Spacecraft Obtains Best Views of Saturn Hexagon
NASA's Cassini spacecraft has obtained the highest-resolution movie yet of a unique six-sided jet stream, known as the hexagon, around Saturn's north pole. This is the first hexagon movie of its kind, using color filters, and the first to show a complete view of the top of Saturn down to about 70 degrees latitude. Spanning about 20,000 miles (30,000 kilometers) across, the hexagon is a wavy jet stream of 200-mile-per-hour winds (about 322 kilometers per hour) with a massive, rotating storm at the center. There is no weather feature exactly, consistently like this anywhere else in the solar system.
6 Nov 2013 Here Comes the Sun: Ionizing Titan's Atmosphere
A detailed analysis of data from NASA's Cassini spacecraft has directly linked the density of the ionosphere - a region in the upper atmosphere that is dominated by electrically charged particles - at Saturn's moon Titan to the 11-year boom-and-bust cycle of activity at our Sun. The confirmation was possible because of Cassini's long-term stay in the Saturn system, which began in 2004, and a Swiss-Army-knife-like suite of many instruments.
17 Oct 2013 NASA Rover Confirms Mars Origin of Some Meteorites
Examination of the Martian atmosphere by NASA's Curiosity Mars rover confirms that some meteorites that have dropped to Earth really are from the Red Planet. A key new measurement of the inert gas argon in Mars' atmosphere by Curiosity's laboratory provides the most definitive evidence yet of the origin of Mars meteorites while at the same time providing a way to rule out Martian origin of other meteorites.
19 Sep 2013 NASA Curiosity Rover Detects No Methane On Mars
Data from NASA's Curiosity rover has revealed the Martian environment lacks methane. This is a surprise to researchers because previous data reported by U.S. and international scientists indicated positive detections. The roving laboratory performed extensive tests to search for traces of Martian methane. Whether the Martian atmosphere contains traces of the gas has been a question of high interest for years because methane could be a potential sign of life, although it also can be produced without biology.
17 Sep 2013 Saturn's Hidden Turbulence Revealed
Peering deeply into Saturn's placid-looking atmosphere with the radar/microwave radiometer aboard NASA's Cassini spacecraft has revealed a dynamic and in many places turbulent atmosphere that has more similarities with that of its sibling planet Jupiter than previously realized. The new observations reveal a calm and narrow equatorial belt surrounded by stormy bands like those on Jupiter, although regions at higher latitudes show a different character that is unique to Saturn.
3 Sep 2013 Cassini Sees Saturn Storm's Explosive Power
A monster storm that erupted on Saturn in late 2010 - as large as any storm ever observed on the ringed planet -- has already impressed researchers with its intensity and long-lived turbulence. A new paper in the journal Icarus reveals another facet of the storm's explosive power: its ability to churn up water ice from great depths. This finding, derived from near-infrared measurements by NASA's Cassini spacecraft, is the first detection at Saturn of water ice. The water originates from deep in Saturn's atmosphere.
18 Jul 2013 MAVEN Spectrometer Opens Window to Red Planet's Past
When NASA's MAVEN mission begins its journey to the Red Planet later this year, it will be equipped with a special instrument to take the planet back in time. That instrument is the Neutral Gas and Ion Mass Spectrometer, a network of electrically charged rods that will measure the charged gas particles -- or ions -- making up Mars' upper atmosphere.
18 Jul 2013 Reports Detail Mars Rover Clues to Atmosphere's Past
A pair of new papers report measurements of the Martian atmosphere's composition by NASA's Curiosity rover, providing evidence about loss of much of Mars' original atmosphere.
18 Jun 2013 The Fast Winds of Venus Are Getting Faster
The most detailed record of cloud motion in the atmosphere of Venus chronicled by ESA's Venus Express has revealed that the planet's winds have steadily been getting faster over the last six years.
13 Jun 2013 MAVEN's Imaging Ultraviolet Spectrograph May Help Paint Total Atmospheric Picture
The Mars Atmosphere and Volatile Evolution Mission, or MAVEN, will travel to the Red Planet in 2013 with instruments designed to answer specific questions about the planet's atmosphere, and one instrument will help piece together the bigger picture. The Imaging Ultraviolet Spectrograph, IUVS for short, designed and built at the University of Colorado Boulder's Laboratory for Atmospheric and Space Physics, known as LASP, will measure Mars' global atmosphere to help solve the mystery of how the planet became frozen and barren.
12 Jun 2013 Mars Water-Ice Clouds Are Key To Odd Thermal Rhythm
Researchers using NASA's Mars Reconnaissance Orbiter have found that temperatures in the Martian atmosphere regularly rise and fall not just once each day, but twice. "We see a temperature maximum in the middle of the day, but we also see a temperature maximum a little after midnight," said Armin Kleinboehl of NASA's Jet Propulsion Laboratory in Pasadena, Calif., who is the lead author of a new report on these findings. Temperatures swing by as much as 58 degrees Fahrenheit (32 kelvins) in this odd, twice-a-day pattern, as detected by the orbiter's Mars Climate Sounder instrument. He and his four co-authors found the answer in the water-ice clouds of Mars.
7 Jun 2013 Noctilucent Clouds Get an Early Start
Every summer, something strange and wonderful happens high above the north pole. Ice crystals begin to cling to the smoky remains of meteors, forming electric-blue clouds with tendrils that ripple hypnotically against the sunset sky. Noctilucent clouds -- a.k.a. "NLCs"-- are a delight for high-latitude sky watchers, and around the Arctic Circle their season of visibility is always eagerly anticipated. This year, NLCs are getting an early start. NASA's AIM spacecraft, which is orbiting Earth on a mission to study noctilucent clouds, started seeing them on May 13th.
5 Jun 2013 Cassini Sees Precursors to Aerosol Haze on Titan
Scientists working with data from NASA's Cassini mission have confirmed the presence of a population of complex hydrocarbons in the upper atmosphere of Saturn's largest moon, Titan, that later evolve into the components that give the moon a distinctive orange-brown haze. The presence of these complex, ringed hydrocarbons, known as polycyclic aromatic hydrocarbons (PAHs), explains the origin of the aerosol particles found in the lowest haze layer that blankets Titan's surface. Scientists think these PAH compounds aggregate into larger particles as they drift downward.
24 May 2013 Big Weather on Hot Jupiters
Among the hundreds of new planets discovered by NASA's Kepler spacecraft are a class of exotic worlds known as "hot Jupiters." Unlike the giant planets of our own solar system, which remain at a safe distance from the sun, these worlds are reckless visitors to their parent stars. They speed around in orbits a fraction the size of Mercury's, blasted on just one-side by starlight hundreds of times more intense than the gentle heating experienced by Jupiter here at home. Meteorologists are probably wondering what kind of weather a world like that might have. The short answer is "big."
21 May 2013 Forecast for Titan: Wild Weather Could Be Ahead
Saturn's moon Titan might be in for some wild weather as it heads into its spring and summer, if two new models are correct. Scientists think that as the seasons change in Titan's northern hemisphere, waves could ripple across the moon's hydrocarbon seas, and hurricanes could begin to swirl over these areas, too. The model predicting waves tries to explain data from the moon obtained so far by NASA's Cassini spacecraft. Both models help mission team members plan when and where to look for unusual atmospheric disturbances as Titan summer approaches.
30 Apr 2013 Why LADEE Matters
Earth's atmosphere is critically important to all of us. In addition to providing us with air to breathe, it protects us from temperature extremes, harmful space radiation and vast numbers of incoming meteoroids. The atmosphere is a very complex system that we are only beginning to understand. Gaining a better understanding of the atmosphere, how it protects us and how we can protect it is in all of our interests. In order to understand Earth's atmosphere and how it works, it is essential to study atmospheres under a wide range of conditions beyond Earth. Examining atmospheres on other planets allows this.
29 Apr 2013 Cassini Gets Close-up Views of Large Hurricane on Saturn
NASA's Cassini spacecraft has provided scientists the first close-up, visible-light views of a behemoth hurricane swirling around Saturn's north pole. In high-resolution pictures and video, scientists see the hurricane's eye is about 1,250 miles (2,000 kilometers) wide, 20 times larger than the average hurricane eye on Earth. Thin, bright clouds at the outer edge of the hurricane are traveling 330 mph (150 meters per second). The hurricane swirls inside a large, mysterious, six-sided weather pattern known as the hexagon.
