Even dying stars could host planets with life -- and if such life exists, we might be able to detect it within the next decade. This encouraging result comes from a new theoretical study of Earth-like planets orbiting white dwarf stars. Researchers found that we could detect oxygen in the atmosphere of a white dwarf's planet much more easily than for an Earth-like planet orbiting a Sun-like star.

Scattered around the Milky Way are stars that resemble our own sun--but a new study is finding that any planets orbiting those stars may very well be hotter and more dynamic than Earth.

Melt Water on Mars Could Sustain Life

Near surface water has shaped the landscape of Mars. Areas of the planet's northern and southern hemispheres have alternately thawed and frozen in recent geologic history and comprise striking similarities to the landscape of Svalbard.

Insights From Mars-like Places on Earth

Life thrives on Planet Earth. In even the most inhospitable places -- the freezing Antarctic permafrost, Sun-baked salt pans in Tunisia or the corrosively acidic Rio Tinto in Spain -- pockets of life can be found. Some of these locations have much in common with environments found on Mars, as discovered by orbiters and rovers exploring the surface.

Astronomers have discovered a veritable rogues' gallery of odd exoplanets -- from scorching hot worlds with molten surfaces to frigid ice balls.

A team of astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) has spotted sugar molecules in the gas surrounding a young Sun-like star.
