Christian theologists have long grappled with how the discovery of extraterrestrial life would fit within the parameters of Christian history and ideology. Unsurprisingly, opinions on the matter are diverse.
Gliese 832c, discovered by a team of Australian scientists, is among the top three most similar known planets to Earth.
This week the agency put out a Request for Information in hopes of attracting creative thinkers who can help them "achieve the most science at minimum cost."
With help from NASA's Kepler space telescope, astronomers have calculated that of all the stars in our galaxy that resemble our sun, one in five hosts an Earth-sized planet at a distance that allows for liquid water at the surface.
A network of probes that communicate with each other using the power of the stars isn't within the reach of current technology, but it could be someday, according to a new paper.
The ethics of "first contact" was the subject of a panel discussion at last week's Starship Congress, where attendees hashed out the logistics and consequences of becoming an interstellar civilization.
This week the International Astronomical Union, long responsible for giving planets sexy names like "HD 189733b," surprised many by opening the process to the general public. Not surprisingly, there are some rules involved. (Sit down, Trekkies.)
Scientists are growing more confident that Jupiter's moon could harbor life. The problem: Getting through its thick ice crust to the watery ocean beneath.
At least that's the claim being made by a new study: The likelihood of a red dwarf star housing a habitable super-Earth increases significantly when cloud behavior is considered.
Two scientists argue that if NASA could get over its fear of contaminating other planets with homegrown microbes, it could save a significant amount of money on its exploration missions.
On Thursday (June 27) PayPal announced a new initiative that will research possible protocols for off-world currency transactions. With space tourism opportunities around the corner, it's not so farfetched an idea.
It's the first arrangement of its kind to be discovered in the hunt for exoplanets that could support life. These planets are among several that orbit Gliese 667C, one star in a trinary star system.
The people behind the Lone Signal project are inviting the public to contribute text and photo messages that they plan to beam into outer space as a beacon to aliens.
Ganymede and Europa have many of the conditions that could support life as we know it. We'll find out if and when an internationally-sponsored probe -- Jupiter Icy Moons Explorer, or JUICE -- gets there in 2030.
While recent focus has been on finding an Earth-like exoplanet in a system's "Goldilocks zone," one astrophysicist suggests that that zone might be made wider by taking other atmospheric conditions, such as greenhouse gas amounts, into account.
