New Theory Can Predict Global Dust Storms on Mars

NASA October 5, 2016 This graphic indicates a similarity between 2016 (dark blue line) and five past years in which Mars has experienced global dust storms (orange lines and band), compared to years with no global dust storm (blue-green lines and band). The horizontal scale is time-of-year on Mars. ______________________________________ Global dust storms on Mars could soon become more predictable ... Read More »

Jupiter’s Unusual Polar Regions – Unlike Anything Seen Before

NASA September 2, 2016 NASA’s Juno spacecraft has sent back the first-ever images of Jupiter’s north pole, taken during the spacecraft’s first flyby of the planet with its instruments switched on. The images show storm systems and weather activity unlike anything previously seen on any of our solar system’s gas-giant planets. Juno successfully executed the first of 36 orbital flybys ...

Gullies on Mars Probably Not Formed by Water

NASA JPL July 29, 2016 New findings using data from NASA’s Mars Reconnaissance Orbiter show that gullies on modern Mars are likely not being formed by flowing liquid water. This new evidence will allow researchers to further narrow theories about how Martian gullies form, and reveal more details about Mars’ recent geologic processes. Scientists use the term “gully” for features ... Read More »

Mars Has Some Weird, Un-Earthlike Sand Dunes

NASA JPL June 30, 2016 Some of the wind-sculpted sand ripples on Mars are a type not seen on Earth, and their relationship to the thin Martian atmosphere today provides new clues about the atmosphere’s history. The determination that these mid-size ripples are a distinct type resulted from observations by NASA’s Curiosity Mars rover. Six months ago, Curiosity made the ... Read More »

Kepler Mission Verifies 1,284 New Exoplanets

NASA May 10, 2016 NASA’s Kepler mission has verified 1,284 new planets – the single largest finding of planets to date. “This announcement more than doubles the number of confirmed planets from Kepler,” said Ellen Stofan, chief scientist at NASA Headquarters in Washington. “This gives us hope that somewhere out there, around a star much like ours, we can eventually ...

Cassini Finds Titan’s Highest Mountain

NASA JPL March 24, 2016 In a nod to extraterrestrial mountaineers of the future, scientists working on NASA’s Cassini mission have identified the highest point on Saturn’s largest moon, Titan. Titan’s tallest peak is 10,948 feet (3,337 meters) high and is found within a trio of mountainous ridges called the Mithrim Montes. The researchers found that all of Titan’s highest ... Read More »

Scientists Find a Possible Ninth Planet in Our Solar System

NASA January 21, 2016 Caltech researchers have found evidence of a giant planet tracing a bizarre, highly elongated orbit in the outer solar system. The object, which the researchers have nicknamed Planet Nine, has a mass about 10 times that of Earth and orbits about 20 times farther from the sun on average than does Neptune (which orbits the sun ...

Enormous Ice Cloud Covers Titan’s South Pole

NASA November 11, 2015 New observations made near the south pole of Titan by NASA’s Cassini spacecraft add to the evidence that winter comes in like a lion on this moon of Saturn. Scientists have detected a monstrous new cloud of frozen compounds in the moon’s low- to mid-stratosphere – a stable atmospheric region above the troposphere, or active weather ... Read More »

Saturn’s Moon Enceladus Has a Global Ocean

NASA JPL September 15, 2015 A global ocean lies beneath the icy crust of Saturn’s geologically active moon Enceladus, according to new research using data from NASA’s Cassini mission. Researchers found the magnitude of the moon’s very slight wobble, as it orbits Saturn, can only be accounted for if its outer ice shell is not frozen solid to its interior, ... Read More »

Newly Discovered Planet is Like Jupiter in Its Infancy

NASA August 14, 2015 One of the best ways to learn how our solar system evolved is to look at younger star systems in the early stages of development. Recently, a team of astronomers including NASA scientists discovered a Jupiter-like planet within a young system that could serve as a decoder ring for understanding how planets formed around our sun. ...
