Recent data from the Cassini spacecraft just added another local contender in the search for extraterrestrial life.
Life on Mars could be hidden beneath miles of rock billions of years old, a new finding on Earth suggests.
NASA’s Kepler mission has discovered two new potentially habitable planets in a solar system a lot like ours.
NASA's Volkswagen-sized Mars rover, Curiosity, has discovered evidence that Mars could have supported microbial life.
A new list of Earth-like exoplanets has been announced, and we're bringing you the top nine.
The SETI Institute pointed a big radio telescope at some recently discovered exoplanets in habitable zones, looking for telltale signs of alien life.
After an update to atmospheric absorption parameters tweaks the habitable zone around stars, Earth turns out to be a lot less habitable than it seems.
It's a subject we can't stop exploring — just how are we going to find alien life forms? Will we receive radio transmissions? Could we stumble upon them as we start asteroid-mining and deep space exploration? Or — could it be their use of hairspray, deodorants and other aerosols that could finally give them away?
If there's life on Mars right now, it's either really good at hiding from our robots, or it's too small to be able to wave at us. In either case, an effective way of finding it might be through gene sequencing, which is why scientists want to send a DNA sequencer on Mars. It's called "the search for extraterrestrial genomes," which I have abbreviated to "SEx GNomes."
The search for extraterrestrial life continues. For three Penn State researchers, the search should not focus on radio waves, as it long has, but on Dyson Spheres....
