When astrobiologists contemplate life on nearby planets or moons, they often suggest such life would be simple. Instead of there being some kind of multicellular organism on, say, Jupiter's moon Europa, scientists instead aim to find something more like a

Skywatchers have a chance to spot the bright planet Jupiter and the moon sparkling brightly in the sky tonight, weather permitting, but only if you know when and where to look.
05 January 2015, 01:42 PM ET
Skywatchers will be treated to a fascinating ballet of the so-called Galilean moons throughout the month, as the satellites pass one another, sometimes blocking (occulting) or casting shadows (eclipsing) and casting shadow onto Jupiter’s cloud tops.

Researchers have trained the Hubble Space Telescope on Europa repeatedly since Europa's geysers were first announced last year, in an attempt to confirm and characterize the plumes. But they've come up empty.
15 December 2014, 01:40 PM ET
Skywatchers with telescopes on Earth will be able to witness a remarkable cosmic event tonght: Two of Jupiter's moons will cast shadows on the face of the gas giant in the same night.

One of the treats awaiting owners of a new telescope is their first look at the giant planet Jupiter and its four tiny moons.

The way we define life has consequences for the search for life on other worlds such as Mars, Jupiter's moon Europa and the Saturn satellite Enceladus.
02 December 2014, 11:00 AM ET
With luck, skywatchers can catch sight of the five brightest planets in the sky this month. Mercury, Mars, Venus, Saturn and Jupiter should all be on display.

Binary Earth-size planets that orbit each other might exist around distant stars, researchers say. Simulations suggest such worlds can begin circling each other after slow, grazing collisions.
20 November 2014, 02:01 PM ET
The strength of an alien world's magnetic field may have been deduced for the first time, by analyzing fast winds slamming against it from the planet's star. The research could help gauge the strength of other exoplanets' magnetic fields as well.

The Great Red Spot on Jupiter's face is secretly dull in color. But the swirling storm looks crimson thanks to something like a cosmic "sunburn." Gases in Jupiter's upper atmosphere turn reddish when they're hit with sunlight, scientists say.

If you were up late Friday night, or rather awake in the wee hours of Saturday, you may have seen two brilliant objects that will immediately catch your eye if the sky is clear.

Big slabs of ice are sliding over and under each other within Europa's ice shell, a new study suggests. The Jovian satellite may thus be the only solar system body besides Earth to possess an active system of plate tectonics.
05 September 2014, 06:40 AM ET
In December 2013, researchers using NASA's Hubble Space Telescope announced they had spotted evidence of geysers erupting from Europa's south polar region. But follow-up Hubble observations in January and February showed no signs of the plumes.
