Europa's gravity is approximately 13% of Earth's. The temperature on Europa varies from −160 °C at the equator, to −220 °C at either of its poles. [145] Europa's subsurface ocean is thought to be significantly [clarification needed] warmer however. It is hypothesized that because of radioactive and tidal heating (as mentioned in the ...
This is a list of most likely gravitationally rounded objects (GRO) of the Solar System, which are objects that have a rounded, ellipsoidal shape due to their own gravity (but are not necessarily in hydrostatic equilibrium). Apart from the Sun itself, these objects qualify as planets according to common geophysical definitions of that term.
The kids all get involved to help create the perfect date night. "Face on the Fritz": When the kids are trying to build a new pet house for Sunspot and FACE 9000 gives them mixed-up directions, they learn that it is time for FACE 9000 to get upgraded.
The high-gain antenna operates on X-band frequencies of 7.2 and 8.4 gigahertz, and a Ka-band frequency of 32 gigahertz (12 times that of a typical cell phone).The antennas will be used to research gravity and radio science, allowing researchers to learn more about Europa's gravity [88] It was designed and constructed by a team led by Matt Bray ...
New research suggests there's less oxygen on the icy surface of Jupiter's moon Europa than thought — and that could affect what if any life might be lurking in the moon’s underground ocean.
NASA is weeks away from sending its Clipper orbiter on a journey to the Jupiter moon Europa, which scientists believe could harbor conditions for life. NASA plans for launch of Europa Clipper ...
The goal of the mission is to determine the thickness of Europa's icy shell and how it interacts with the ocean below. (Scripps News) NASA’s Europa Clipper launches from Kennedy Space Center [Video]
Europa reveals more dynamic and recent movement of this nature, suggesting a thinner ice crust. Finally, Io, the innermost moon, has a sulfur surface, active volcanism and no sign of ice. All this evidence suggests that the nearer a moon is to Jupiter the hotter its interior.
