Lessons from Earth suggest that intelligence and aggression might evolve hand-in-hand.
The last thing scientists searching for life on Mars want to find is a colony of hitchhiking microbes from Earth. To that end, an experiment poised to begin week aims to put some of the planet’s most tenacious bacteria through an ultimate survivors’ challenge.
Although scientists have long considered oxygen a sign that life exists on an alien planet, new research suggests the element could be produced without it.
Red dwarf stars may be able to support habitable exoplanets after all -- through complex tidal interactions between star and planet, global magnetic fields could evolve, protecting hypothetical life forms from the red dwarfs' ferocious nature.
Our solar system has some prime locations (besides Earth) for alien life.
It might kill us, but the perchlorate-rich liquid water of Mars could be our best opportunity yet of rooting out the possibility of microbial Martian life.
Earlier this month, the ExoMars launch date was pushed back by a couple of months. Instead of launching in January 2016, the European mission will launch the following March -- but still get to Mars at nearly the same time. How is this possible?
The discovery of seasonal water flows on the surface of Mars could galvanize both the search for indigenous life as well plans for future human settlements, but don’t pack your bags quite yet.
