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
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.
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?
A while ago, we were telling you about the discovery of a huge exoplanet – a gas giant, found just 155 light years away from Earth. The head researcher behind that study was Marie-Eve Naud. Her main research field is the detection and characterization of exoplanets, with a focus on astrobiology. She was kind enough to talk to us and shed some
Evidence of surprisingly diverse life forms have been found in the 100.000 year old sediments of a subglacial lake in Antarctica. British scientists working on the site have apparently gathered samples without contaminating them. The possibility of life existing in these cold, dark lakes, hidden beneath (sometimes) kilometers of ice has fascinated researchers. We’re talking about bacteria living in environments
If you were to lick the surface of Jupiter‘s icy moon Europa, you would actually be sampling a bit of the ocean beneath – at least that’s what a new paper by Mike Brown, an astronomer at the California Institute of Technology in Pasadena, Calif., and Kevin Hand from NASA’s Jet Propulsion Laboratory concludes. Their work details the strongest evidence
It’s been quite a while since we published anything about the Cassini mission, but that doesn’t mean it hasn’t been active. The information it keeps sending back to Earth is priceless, and at some points, totally surprising. This was also the case of the Saturn Moon Enceladus, which appears to give out much more heat than previously estimated, according to
Wherever it’s possible, life finds a way; the old saying seems to be more and more actual these days, with NASA and other space agencies reporting interesting discoveries that point towards life existing in many more other places other than our own planet. After rewriting the biology books with the arsenic eating microbe, NASA researchers claim to have found evidence
