14 lug 2014 · Credits: NASA. Many scientists believe we are not alone in the universe. It’s probable, they say, that life could have arisen on at least some of the billions of planets thought to exist in our galaxy alone — just as it did here on planet Earth.

Is there life beyond Earth? Whether elsewhere in our own solar system, or farther out among the exoplanets, that question is still unanswered. But the answers might be getting closer. And many recent discoveries seem to bolster the possibility of extraterrestrial life. September 2022 has been a great illustration, with the announcements of several ...
First, Enceladus. Like Jupiter’s moon Europa, this small moon of Saturn is thought to have a subsurface ocean of liquid water. In 2018, a new analysis of data from NASA’s Cassini spacecraft – obtained when the spacecraft flew through water vapor plumes, erupting into space from this subsurface ocean – found some tantalizing ingredients suggesting E...
Astronomer Chris Impey posted another intriguing article in The Conversation on September 23, 2022. In it, he makes the case that super-Earths – exoplanets larger and more massive than Earth but smaller and less massive than Neptune – might not just be habitable. They might be even more habitablethan our own Earth. They are also common, estimated n...
For decades, scientists have debated whether Mars was warmer and wetter a few billion years ago. Or was it cold and wet? Or cold and mostly dry? A new press release from the SETI Institute outlines new evidence that Mars was born wet, with a dense atmosphere. That could have allowed warm oceans to exist for millions of years. The researchers develo...
Another study, from researchers in Hong Kong, also supports a previously wetter Mars. The study suggests that scientists have underestimated the number of lakes that once existed on Mars. According to Joseph Michalski, a geologist at the University of Hong Kong: According to the new paper, most of the already known Martian lakes date back to about ...
Finally, Space.com reported that China’s Zhurong rover has found new evidence for an ancient ocean on Mars. Zhurong is exploring the ancient plains of Utopia Planitia. If, as some scientists contend, Mars did once have an ocean, then Utopia Planitia, a huge basin, was likely part of it. According to the China National Space Administration (CNSA), t...
While none of these new findings provethere is extraterrestrial life, they do show that the possibilities are increasing. While we still only know about life on Earth, there may be multiple scenarios – both in our solar system and far beyond – in which living organisms could originate and evolve. Where will we find the first definitive evidence? In...
1 ago 2022 · The search for life beyond the Earth is being carried out using a variety of techniques in three distinct realms of space. The best near-term prospect for the detection of life is the detection of biomarkers in exoplanet atmospheres.
