Low-cost design could help farmers in Ethiopia maintain self-sufficient agriculture.
Unexpected bright spots discovered on the surface of the dwarf planet Ceres may be plumes of ice blasting out into space.
Our solar systems moons keep showing evidence for liquid water. These exciting discoveries have scientists re-examining how we should look for life "out there," and where we should look.
Saturn's icy moon Enceladus is showing definite signs of hydrothermal activity -- similar activity that is found along deep sea vents on Earth where water is heated and minerals are formed.
Hints that Jupiter's moon Ganymede, the largest moon in the solar system, has a subsurface ocean date back more than 40 years, but it took the Hubble Space Telescope and some clever scientific detective work by to come up with the proof.
Does it exist or not? Astronomers are claiming that the potentially habitable exoplanet is just noisy data, while others say it's too early to discount the existence of Gliese 581d.
By mapping the distribution of water and 'semi-heavy water' over the Martian surface, scientists have revealed that the red planet had an ancient ocean covering nearly 20 percent of its landmass.
NASA's Dawn mission is about to arrive in orbit around Ceres and the hunt for the dwarf planet's past (and possibly present) habitable potential is on.
