Life on Europa could exist clustered around hydrothermal vents on the ocean floor, or below the ocean floor, where endoliths are known to inhabit on Earth. Alternatively, it could exist clinging to the lower surface of Europa's ice layer, much like algae and bacteria in Earth's polar regions, or float freely in Europa's ocean. [ 188 ]
Natural satellites that host life are common in (science-fictional) written works, films, television shows, video games, and other popular media. factual satellite, fictional life Europa, Callisto, Ganymede, Io and Titan in "Cowboy Bebop" (1998) The Moon in A Trip to the Moon (1903) and many other films; Europa in Europa Report (2013) and ...
This is a list of confirmed exoplanets within the circumstellar habitable zone that are either under 10 Earth masses or smaller than 2.5 Earth radii, and thus have a chance of being rocky.
We're just looking for the conditions for life," Buratti added. Europa Clipper is the biggest spacecraft NASA has ever built for a planetary mission, measuring about 100 feet (30.5 meters) long ...
False-color Cassini radar mosaic of Titan's north polar region; the blue areas are lakes of liquid hydrocarbons. "The existence of lakes of liquid hydrocarbons on Titan opens up the possibility for solvents and energy sources that are alternatives to those in our biosphere and that might support novel life forms altogether different from those on Earth."—NASA Astrobiology Roadmap 2008 [1]
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.
A team of international researchers has challenged the long-held belief that complex life forms first emerged on Earth 635 million years ago, presenting findings that show life may have existed ...
NASA had previously evaluated a Europa Lander concept in 2005 with the Europa Lander Mission concept. [6] Also, a lander was evaluated in 2012. [7] There was continued support for Europa missions, including in 2014, when the U.S. Congress House Appropriations Committee announced a bipartisan bill that included US$80 million in funding to continue the Europa mission concept studies.
