Cassini sees sunny seas on Titan
(Phys.org) —As it soared past Saturn's large moon Titan recently, NASA's Cassini spacecraft caught a glimpse of bright sunlight reflecting off hydrocarbon seas.
Cassini watches mysterious feature evolve in Titan sea
(Phys.org) —NASA's Cassini spacecraft is monitoring the evolution of a mysterious feature in a large hydrocarbon sea on Saturn's moon Titan. The feature covers an area of about 100 square miles (260 square ...
Seven tiny grains captured by Stardust likely visitors from interstellar space
Since 2006, when NASA's Stardust spacecraft delivered its aerogel and aluminum foil dust collectors to Earth, a team of scientists has combed through the collectors in search of rare, microscopic particles ...
Rosetta measures comet's temperature
(Phys.org) —ESA's Rosetta spacecraft has made its first temperature measurements of its target comet, finding that it is too hot to be covered in ice and must instead have a dark, dusty crust.
Transiting exoplanet with longest known year
Astronomers have discovered a transiting exoplanet with the longest known year. Kepler-421b circles its star once every 704 days. In comparison, Mars orbits our Sun once every 780 days. Most of the 1,800-plus ...
Ocean on Saturn moon could be as salty as the Dead Sea
(Phys.org) —Scientists analyzing data from NASA's Cassini mission have firm evidence the ocean inside Saturn's largest moon, Titan, might be as salty as the Earth's Dead Sea.
Sunsets on Titan reveal the complexity of hazy exoplanets
(Phys.org) —Scientists working with data from NASA's Cassini mission have developed a new way to understand the atmospheres of exoplanets by using Saturn's smog-enshrouded moon Titan as a stand-in. The ...

Venus Express gets ready to take the plunge
(Phys.org) —After eight years in orbit, ESA's Venus Express has completed routine science observations and is preparing for a daring plunge into the planet's hostile atmosphere.
NASA Cassini images may reveal birth of a Saturn moon
(Phys.org) —NASA's Cassini spacecraft has documented the formation of a small icy object within the rings of Saturn that may be a new moon, and may also provide clues to the formation of the planet's known ...
Surface of Titan Sea is mirror smooth, scientists find
New radar measurements of an enormous sea on Titan offer insights into the weather patterns and landscape composition of the Saturnian moon. The measurements, made in 2013 by NASA's Cassini spacecraft, reveal ...
Mercury contracted more than prior estimates, evidence shows
New evidence gathered by NASA's MESSENGER spacecraft at Mercury indicates the planet closest to the sun has shrunk up to 7 kilometers in radius over the past 4 billion years, much more than earlier estimates.
Venus Express spacecraft, low on fuel, does delicate dance above doom below
It's been an interesting year for Venus Express. A few months ago, controllers deliberately dipped the spacecraft into the atmosphere of the planet—for science purposes, of course. The daring maneuver was ...
New process can convert human-generated waste into fuel in space
Human waste may have a new use: sending NASA spacecraft from the moon back to Earth.
