A team of astronomers needs your help with the hunt for alien life, and they're offering some pretty cool exoplanet swag in return.
Aliens can refer to everything from little green men in the sci-fi realm to microscopic life forms beyond Earth. For all these possibilities, Live Science has you covered. We break down the latest discoveries that hint at life on other planets and the state of scientific searches for such extraterrestrial life. Sometimes, we may dissect a "little green man" sighting as well.
The search for signs of extraterrestrial life extends from eavesdropping on radio signals, to observing the atmospheres on distant worlds.
Astrobiologists ponder sending gene sequencers, weather stations, drilling rigs and more to the Red Planet
Some of the first spacecraft that humanity sends to other solar systems may carry microscopic ambassadors from Earth.
The first fleet of robotic spacecraft that humanity launches to explore nearby exoplanets may include a few kamikazes.
Film director Ridley Scott suggests that intelligent aliens are "out there," and Earth's inhabitants should prepare for the worst.
The same sorts of chemical reactions that sustain life near deep-sea hydrothermal vents here on Earth could be occurring within Enceladus' subsurface ocean, a new study suggests.
A new paper suggests using a combination lottery and savings bond to ensure funding for the search for extraterrestrial intelligence.
Bizarre flashes of cosmic light may actually be generated by advanced alien civilizations, as a way to accelerate interstellar spacecraft to tremendous speeds, a new study suggests.
Winston Churchill was known for his leadership during World War II, but a newfound essay on alien life reveals another side of him, one that was deeply curious about the universe.
If high altitude balloons find basic microorganisms in the stratosphere and mesosphere, it could have serious implications for the hunt for extraterrestrial life in the atmospheres of other worlds.
The Wolf 1061 star system is only 14 light-years away and a team of astronomers are doing the groundwork to begin looking for signs of extraterrestrial biology in one of its planet's atmospheres.
Astronomers may have to think a little harder to solve the mystery of Boyajian's star, whose strange dimming events over the past seven years have spawned talk of a possible "alien megastructure."
To aid in the search for life on Mars, people should look at the way primitive life on Earth modifies the environment around it.
There's a huge hole in the sun, but it has nothing to do with alien spaceships or any other conspiracy theory.
Weird and mysterious radio signals coming from outer space often are followed by claims of "aliens did it." That's likely not the case, says one astrophysicist.
What would happen if humans really did make contact with an intelligent alien civilization? If E.T. calls, is there a plan?
