Planetary habitability in the Solar System is the study that searches the possible existence of past or present extraterrestrial life in those celestial bodies. As exoplanets are too far away and can only be studied by indirect means, the celestial bodies in the Solar System allow for a much more detailed study: direct telescope observation, space probes, rovers and even human spaceflight.
Jupiter: Callisto – potential habitability: Thought to have a subsurface ocean heated by tidal forces. [41] [42] Ganymede: Jupiter: Ganymede – Subsurface oceans: Thought to have a magnetic field, with ice and subterranean oceans stacked up in several layers, with salty water as a second layer on top of the rocky iron core. [43] [44] Io: Jupiter
NASA is set to launch a spacecraft to Jupiter's moon Europa, considered one of our solar system's most promising spots to search for life beyond Earth, to learn whether this ice-encased world ...
While Earth is the only place in the Universe known to harbor life, [10] [11] estimates of habitable zones around other stars, [12] [13] along with the discovery of thousands of exoplanets and new insights into the extreme habitats on Earth where organisms known as extremophiles live, suggest that there may be many more habitable places in the ...
At 16:06 GMT, NASA launched the Europa Clipper ship from Cape Canaveral, Florida, to search for signs of life on one of Jupiter’s frozen moons. “Discovering life on other celestial bodies ...
NASA launched a spacecraft from Florida on Monday on a mission to examine whether Jupiter's moon Europa has conditions suitable to support life, with a focus on the large subsurface ocean believed ...
Rare Earth argues that complex life cannot exist on large gaseous planets like Jupiter and Saturn (top row) or Uranus and Neptune (top middle) or smaller planets such as Mars and Mercury. The Rare Earth hypothesis argues that life requires terrestrial planets like Earth, and since gas giants lack such a surface, that complex life cannot arise ...
Coverage of the launch is expected to begin at 11 a.m. ET and will be added to this story in the video player above. The launch window itself is set to open at 12:06 p.m. ET.
