Internal structure of Europa. The blue represents a subsurface ocean. Such subsurface oceans could possibly harbor life. [55] Europa may have a liquid ocean beneath its icy surface, which may be a habitable environment. This potential ocean was first noticed by the two Voyager spacecraft, and later backed by telescope studies from Earth.
As the name suggests, the continuously habitable zone is a region around a star in which planetary-mass bodies can sustain liquid water for a given period. Like the general circumstellar habitable zone, the continuously habitable zone of a star is divided into a conservative and extended region. [92]
The only ways in which potential life could avoid either an inferno or a deep freeze would be if the planet had an atmosphere thick enough to transfer the star's heat from the day side to the night side, or if there was a gas giant in the habitable zone, with a habitable moon, which would be locked to the planet instead of the star, allowing a ...
Jupiter -- and, by association, Europa -- is well outside the "habitable zone," the gauge astronomers have used for years to determine whether a planet can sustain liquid water, a major precursor ...
A SpaceX Falcon Heavy rocket carrying NASA's Europa Clipper space probe launches from Kennedy Space Center on Oct. 14, 2024, on a mission to orbit Jupiter and study its icy moon, Europa, for signs ...
The aim of Europa Clipper is to explore Europa in order to investigate its habitability, and to aid in selecting sites for a future lander. The Europa Clipper would not orbit Europa, but instead orbit Jupiter and conduct 45 low-altitude flybys of Europa during its envisioned mission. The probe would carry an ice-penetrating radar, short-wave ...
In 2012, scientists introduced a concept to define the habitable orbits of moons. [30] The concept is similar to the circumstellar habitable zone for planets orbiting a star, but for moons orbiting a planet. This inner border, which they call the circumplanetary habitable edge, delimits the region in which a moon can be habitable around its planet.
Habitable zone for complex life (HZCL): the place that all the life habitable zones overlap for a long period of time, as in the Solar System. [90] The list of habitable zones for complex life has grown longer with increasing understanding of the Universe, galaxies, and the Solar System.
