Earth-born methanogen bacteria species could survive in Mars’ crust, new study shows

Life can be surprisingly hardy.

NASA’s mission to search for life on Europa takes shape

If we want to look for extraterrestrial life, Europa might be one of the best guesses in the solar system.

NASA finds more evidence of water plumes on Europa

Europa’s water is acting up.

SETI observes a “strong signal,” but don’t get your hopes up just yet

A star system 94 light-years away stepped in as a potential candidate for intelligent life.

‘Goldilocks area’ not nearly enough for habitable planets – internal temperature is also important

A Yale University researcher claims that the so-called Goldilocks planetary area only tells half of the story.

The reason why we haven’t found alien life yet might be because we’re searching too soon

We might be too early for the party. Darn!

Saturn’s Moon Titan might host life, researchers report

Life on Titan? It’s a good bet.

Jupiter’s moon Europa could have Earth-like oceans

If I asked you to guess where we have the best chances of finding life outside of Earth, you’d be hard pressed to think about Europa. But Jupiter’s frozen moon is beginning to look more and more attractive, and may even harbor an Earth-like ocean. We’ve written extensively before about the life harboring possibilities of Jupiter’s moon, Europa. Beneath the

Computer models confirm icy eruptions on Saturn’s Moon

A few years ago, the Cassini spacecraft made a surprising discovery: there are geysers erupting on Saturn’s moon Enceladus, spewing water and ice to great heights. However, the process which causes these geysers remained unknown or controversial. Now, scientists at the University of Chicago and Princeton University have pinpointed a mechanism through which Saturn’s tidal forces exert constant stress and cause

Observing Alien Armageddon could be our first sign of advanced civilizations in space.

It may be possible to observe the presence of an advanced alien civilization by the effects produced if that civilization were to self-destruct through nuclear war, biological warfare, nanotechnological annihilation, or stellar pollution. Each case would generate unique detectable signs that could be identified by earth-based telescopes.

Pleasant thought of the Day: the galaxy may be a graveyard full of dead aliens

Where are all the aliens? Why haven’t we seen or heard their signals from space? Could we really have been the only planet where life evolved?

NASA prepares for historic Cassini flyby

NASA is preparing for a historical approach to Enceladus, plunging its Cassini spacecraft deep through the icy spray coming from the ocean on Enceladus.

Alien life might spread through the Universe “like the plague”

Although we’ve yet to discover life forms on any other planet, astronomers are confident that not only we’ll be able to discover alien life, but we’ll be able to chart its spread through the Universe.

Your smartphone can help Stephen Hawking discover alien life

This week space fanatics were teeming with excitement after it was announced that Stephen Hawking had teamed up with Russian billionaire Yuri Milner in a quest to find extraterrestrial life.

Life on comets? Not so fast, astronomers say!

Yesterday, we presented an article in which we detailed the claims of two astronomers, Director of the Buckingham Centre for Astrobiology professor Chandra Wickramasinghe and his colleague Dr Max Wallis from the University of Cardiff; they proposed that Rosetta’s lander Philae may have actually landed on an inhabited comet – as the black slime on the surface suggests. However, the rest

Philae could be sitting on a comet filled with alien life and not even know it

Comet lander Philae may be sitting on top of microbial life and not even know it – even worse, it has no way of figuring out if it actually is. According to two researchers, the comet’s characteristics (as well as computer simulations) might indicate that the surface may be teeming with microbes. The Rosetta spacecraft was launched in March 2004 by

Earth-sized planets all have relatively circular orbits, study finds

For decades, researchers have studied our planet’s orbit with growing interest: is there something special about the way the Earth revolves around the Sun, is it a necessary condition for life to emerge? A team of researchers from MIT studied 74 Earth-sized exoplanets and reports that all of them have fairly circular orbits around their stars. Circular vs Eccentric The

NASA presents toolkit to search for life on Jupiter’s Moon Europa

Sending a probe to look for alien life is just half of the work – it’s the tools you send there that will actually do the job, and NASA has decided which tools it wants to send to Jupiter’s moon Europa, a place considered by many the likeliest to hold alien life.

Algae and bacteria will provide oxygen for astronauts living on Mars

NASA has partnered with a private company to design and build an oxygen production facility for a Martian outpost or colony. The make the oxygen, bacteria and algae would use the nitrogen-rich Martian soil to make the precious oxygen, essential for the astronauts’ survival. It can be used to make air, water and fuel.

NASA officially starts program to look for alien life

Just after NASA researchers made the bold claim that they will find alien life in less than 20 years, the space agency has officially launched a project to look for it. The Nexus for Exoplanet System Science, or “NExSS” will be a project integrating several fields of science, aiming to better understand exoplanets with the potential to host life, as well as planet-life interactions.
