In the light of recent news that there may be giant plates of ice shuffling around Jupiter's moon Europa - much as plates of rock do on the Earth - NASA is seeking ideas for instruments that could fly on a mission to Europa.
In a significant discovery using NASA`s Hubble Space Telescope, astronomers, including an Indian-origin researcher, who went looking for water vapour in three exoplanets orbiting stars similar to our sun have come up nearly dry.
To unlock the mystery behind how the cores of `super-Earths` or giant planets like Jupiter respond to intense atmospheric pressure, US researchers have blasted a diamond with the world`s biggest laser beam at a very high pressure.
In what could lead to better understanding of how giant planets form, researchers have experimentally recreated the conditions that exist deep inside giant planets, such as Jupiter, Uranus and many other planets recently discovered outside the solar system.
Although our planet Earth only has one Moon, most other planets (except Mercury and Venus, which have no natural satellites or moons of their own and Mars, which has just two moons that are small irregular sized objects) have a large number of moons revolving around them.
