Gassy signature of habitability spied in the atmosphere of a 'hot Jupiter'. Katharine Sanderson. Carbon dioxide, one of the telltale signs that a planet may be able to support life, has been spotted in the atmosphere of a gas giant orbiting a star 63 light years from Earth.
The temperature in Jupiter's upper atmosphere is around -145C (-230F). Deeper below the clouds the temperate reaches 21C (70F). Near the planet's center the temperature is around six times hotter than the surface of the Sun! Jupiter has 62 moons, 16 of which have a diameter of at least 6 miles.The four main moons of Jupiter are Io, Europa, Ganymede and Callisto, all discovered in 1610 by Galileo and referred to as the Galilean Moons. The gas giant is the largest planet in the solar system with a diameter of around 89,000 miles (143,000 km). 2  Jupiter is 11 times larger than Earth in diameter and around 10% as large as the sun.
