Where the Ice is on Ceres – New Findings

NASA JPL December 15, 2016 At first glance, Ceres, the largest body in the main asteroid belt, may not look icy. Images from NASA’s Dawn spacecraft have revealed a dark, heavily cratered world whose brightest area is made of highly reflective salts — not ice. But newly published studies from Dawn scientists show two distinct lines of evidence for ice ... 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 »

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 ...

Finding Other Earth-like Planets

NASA JPL July 23, 2015 image: The discovery of a super-Earth-sized planet orbiting a sun-like star brings us closer than ever to finding a twin of our own watery world. But NASA’s Kepler space telescope has captured evidence of other potentially habitable planets amid the sea of stars in the Milky Way galaxy. image: To take a brief tour of ... Read More »

Comet Jets Are Coming From Large Sinkholes

ESA July 1, 2015 A number of the dust jets emerging from Rosetta’s comet can be traced back to active pits that were likely formed by a sudden collapse of the surface. These ‘sinkholes’ are providing a glimpse at the chaotic and diverse interior of the comet. Rosetta has been monitoring Comet 67P/Churyumov–Gerasimenko’s activity for over a year, watching how ...

Glass Deposits Detected on Mars

NASA JPL June 8, 2015 NASA’s Mars Reconnaissance Orbiter (MRO) has detected deposits of glass within impact craters on Mars. Though formed in the searing heat of a violent impact, such deposits might provide a delicate window into the possibility of past life on the Red Planet. During the past few years, research has shown evidence about past life has ... Read More »

Planet Found With Four Parent Stars

March 4, 2015 NASA JPL — Astronomers have discovered the second known case of a planet residing in a quadruple star system. — The planet was known before, but was thought to have only three stars, not four. — The findings help researchers understand how multiple star systems can influence the development and fate of planets. Growing up as a ... Read More »

What is Causing the Mysterious Martian Plumes?

ESA February 16, 2015 Plumes seen reaching high above the surface of Mars are causing a stir among scientists studying the atmosphere on the Red Planet. On two separate occasions in March and April 2012, amateur astronomers reported definite plume-like features developing on the planet. The plumes were seen rising to altitudes of over 250 km above the same region ... Read More »
