A New Moon Forming in the Rings of Saturn?
April 20, 2014 | NASA

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 moons.

Possible Exomoon Found
April 13, 2014 | NASA

NASA-funded researchers have spotted the first signs of an “exomoon,” and though they say it’s impossible to confirm its presence, the finding is a tantalizing first step toward locating others. The discovery was made by watching a chance encounter of objects in our galaxy, which can be witnessed only once.

The Contraction of Mercury
April 10, 2014 | Carnegie Institution for Science

“Unlike Earth, with its numerous tectonic plates, Mercury has a single rigid, top rocky layer. [...] New global imaging and topographic data from MESSENGER show that the innermost planet has contracted far more than previous estimates.” Quoted from the Carnegie Institution for Science press release.

A Red Mars and a Lunar Eclipse
April 1, 2014 | New Zealand Herald

This week Earth will overtake Mars in its orbit and will be at one of its closest positions to the planet. That will make Mars especially large and red in the night sky. Then, after midnight on April 15th a lunar eclipse will occur. (Details on the lunar eclipse in a Washington Post article.)

A New Dwarf Planet?
March 27, 2014 | NASA

“Scientists using ground based observatories have discovered an object that is believed to have the most distant orbit found beyond the known edge of our solar system. Named 2012 VP113, the object is possibly a dwarf planet. [...] A dwarf planet is an object in orbit around the sun that is large enough to have its own gravity pull itself into a spherical, or nearly round, shape.” Quoted from the NASA press release.

The Search for Planet X Fails
March 20, 2014 | NASA

“After searching hundreds of millions of objects across our sky, NASA’s Wide-Field Infrared Survey Explorer (WISE) has turned up no evidence of the hypothesized celestial body in our solar system commonly dubbed Planet X.” Quoted from the NASA press release.

Colliding Comets
March 16, 2014 | NASA

“Astronomers exploring the disk of gas and dust around a nearby star have uncovered a compact cloud of poisonous gas formed by ongoing rapid-fire collisions among a swarm of icy, comet-like bodies. The researchers suggest the comet swarm is either the remnant of a crash between two icy worlds the size of Mars or frozen debris trapped and concentrated by the gravity of an as-yet-unseen planet.” Quoted from the NASA press release.

Martian Meteorites on Earth
March 13, 2014 | National Geographic

Researchers believe that the shergottite meteorites found on Earth may have originated from an impact that created the Mojave Crater on Mars.

Flows of Water on Mars?

Kepler Finds a Very Wobbly Planet
February 11, 2014 | NASA

“Imagine living on a planet with seasons so erratic you would hardly know whether to wear Bermuda shorts or a heavy overcoat. [...] The planet, designated Kepler-413b, precesses, or wobbles, wildly on its spin axis, much like a child’s top. The tilt of the planet’s spin axis can vary by as much as 30 degrees over 11 years, leading to rapid and erratic changes in seasons. In contrast, Earth’s rotational precession is 23.5 degrees over 26,000 years. Researchers are amazed that this far-off planet is precessing on a human timescale.” Quoted from the NASA press release.

Spectacular New Crater and Ejecta on Mars
February 6, 2014 |

“Space rocks hitting Mars excavate fresh craters at a pace of more than 200 per year, but few new Mars scars pack as much visual punch as one seen in a NASA image released today.” Quoted from the NASA press release (February 5, 2014).

Surprise White Rock on Mars
January 23, 2014 | NASA

While preparing to start robotic arm work on the target “Cape Elizabeth” on Sol 3541 (Jan. 8, 2014), Opportunity encountered a slight surprise — a rock had appeared in the images that had not been there before. This target that has been named “Pinnacle Island” and its origin has been the target of much speculation.

A Star that is Almost Identical to Our Sun

Clay Minerals and a Collision with Europa?
December 15, 2013 | NASA

“A new analysis of data from NASA’s Galileo mission has revealed clay-type minerals at the surface of Jupiter’s icy moon Europa that appear to have been delivered by a spectacular collision with an asteroid or comet. This is the first time such minerals have been detected on Europa’s surface. The types of space rocks that deliver such minerals typically also often carry organic materials.”
