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....
It's been 30 years since the movie E.T. had everyone lining up at the box office, so what better time to swoop in with a special edition package tempt your wallet. After all, people who loved the movie as kids in 1982 are just now entering their peak earning years, with cash to spend on a little childhood nostalgia.
New analysis of an experiment performed by the Viking landers suggests that evidence of microbial life in the Martian soil may have been detected 36 years ago. As one of the authors of this new paper puts it: "on the basis of what we've done so far, I'd say I'm 99 percent sure there's life there." Whoa.
It's going to be a very, very long time before we have a telescope big enough to spot little green men waving at us from the surface of another world. What we might be able to spot in the near future, though, are their farms and gardens, with a spectral technique that looks for the signatures of alien plants in polarized light.
