Astronomers work out how Jupiter- and Saturn-like planets form
Oct 31, 2016 · Astronomers set up two theories explaining how gaseous giant planets like Jupiter or Saturn could be born. A bottom-up formation mechanism states that first, a solid core is aggregated of roughly ten times the size of the Earth.

Jupiter’s ‘light show’ found to pulsate at its poles
NASA’s Chandra X-ray Observatory and ESA’s XMM-Newton Observatory have revealed that Jupiter’s northern and southern aurora pulsate independently to each other. By studying the high-energy X-ray emissions from Jupiter’s aurorae, the south pole consistently pulsate every 11 minutes, whereas the north pole emission is much more erratic.
Hubble watches over Saturn’s powerful aurora - spaceanswers.com
Aug 30, 2018 · The Hubble observations were coordinated with the “Grand Finale” of the Cassini spacecraft, when the spacecraft simultaneously probed the auroral regions of Saturn. The Hubble data allowed astronomers to learn more about Saturn’s magnetosphere, which is the largest of any planet in the Solar System other than Jupiter.
Changes in Jupiter’s Great Red Spot captured by Hubble - All …
In Jupiter’s North Equatorial Belt, the researchers found an elusive wave that had been spotted on the planet only once before, decades earlier, by Voyager 2. In those images, the wave is barely visible, and nothing like it was seen again, until the current wave was found traveling at about 16 degrees north latitude, in a region dotted with ...
Jupiter’s greatest storm found to heat up planet’s atmosphere
Sunlight reaching Earth efficiently heats the terrestrial atmosphere at altitudes well above the surface – even at 250 miles high, for example, where the International Space Station orbits. Jupiter is over five times more distant from the Sun, and yet its upper atmosphere has temperatures, on average, comparable to those found at Earth.
NIGHT SKY: Mars, Saturn and Antares line up in the August twilight
Aug 17, 2016 · Not that the three have anything to do with each other. Mars is the nearest of them, 7 light minutes from Earth (79 million miles). Saturn is almost a dozen times farther away: 82 light minutes (914 million miles). Antares, the lowest of the three in the sky, is about 550 light years in the background, or 3.3 quadrillion miles into deep space.

Why are all the planets different colours if they formed at the …
Jupiter has an atmosphere containing hydrogen and helium, with small amounts of water, ice crystals, ammonia crystals and other elements. These create the clouds of white, orange, brown and red. While the planets formed at the same time (and planetary formation is a complicated process), lighter elements were blown outward by strong solar winds ...
