The debate over possible evidence for life on Mars is one of the most hotly debated subjects in space science, and some news released Feb. 27 is sure to add fuel to the fire. Studies of a Martian meteorite, known [...]
Artist’s impression of an exoplanet with a mass approximately 3.6 times that of Earth, discovered orbiting just inside of the habitable zone of the Sun-like star HD 85512. Are “Super-Earths” such as this the most promising candidates for harboring extraterrestrial life? Image Credit: ESO/M. Kornmesser

A new study published online in the weekly scientific journal Nature on Jan. 22 reports on observations made by the Herschel Space Observatory of water vapour seen coming out [...]
New studies strengthen the case for the possibility of life, carried by asteroids or comets on places like Europa. Image Credit: NASA/JPL/Ted Stryk.
Even though Mars receives most of the spotlight today when it comes to searching for places in the Solar System—besides Earth—where life might have arisen, there are many in the scientific [...]
An enchanting image of Europa hanging above Jupiter’s limb, as seen by the New Horizons probe in 2007, on its way to Pluto. When will we return there and answer one of the most important questions ever asked: Is there life beyond Earth?

For decades, Jupiter’s moon Europa has been the focus of fascination and debate. Why? Because it has a global ocean—a deep, salty ocean similar to those on Earth, except that in Europa’s case it is always covered by a [...]

Ever since the Voyagers beheld its strange, orange-hued veil of hydrocarbon smog, more than three decades ago, Titan has exerted a tantalizing pull on the human psyche. The largest moon of Saturn—and the second-largest-known natural satellite in the Solar [...]
Jupiter’s moon Europa, an ice-covered waterworld. Could life exist there?Photo Credit: NASA / JPL / Ted Stryk.
Jupiter’s moon Europa is often referred to as a “waterworld,” and for good reason: a global ocean almost definitely exists below its outer icy crust, making it a primary focus of interest in the search for life [...]

The idea of journeying to the stars is nothing new. As early as 1929, the British scientist J. D. Bernal wrote about the possibility of generation ships—enormous spacecraft, like miniature worlds, which would take hundreds or thousands of years [...]
