The Hubble Space Telescope recently caught this shot of Jupiter's moon Ganymede just before it ducked behind the giant planet. The largest moon in our solar system, Ganymede is an icy rock even bigger than Mercury.
It's a gorgeous shot, but the image also reveals important information about Jupiter's atmosphere. As Ganymede passes behind the gas giant, light from the planet bounces off the moon, carrying with it clues about the chemicals that make up the haze above the Jovian clouds.The Hubble Space Telescope recently caught this shot of Jupiter's moon Ganymede... more

The gas giant has been quiet for centuries, but two new red spots five or ten times larger than Earth have formed in its atmosphere over the last three years.
If something goes wrong with Jupiter's thermonuclear reactions, it may explode – a catastrophic event which would destroy every living organism on Earth.
Mysterious phenomena have been taking place on one of Jupiter's largest moons as well. Europa's ice-heavy poles shifted 90 degrees last May, exchanging places with its equator.
St. Petersburg-based scientist Eduard Drobyshevsky said Jupiter's other giant moon, Callisto, may be a threat to human existence as well. Since Callisto's shell has never exploded like others have in the past, Drobyshevsky believes it may do so soon. Such an explosion would cause massive pieces of ice to fall down to Earth, exterminating all life.
Drobyshevsky warned: "The explosion of its shell will lead to nuclear winters on Earth. It will be a horrible disaster for the biosphere."The gas giant has been quiet for centuries, but two new red spots five or ten times... more

Three separate groups of scientists have used different computer simulations to predict the same frightening outcome. It is possible the massive gravitational pull of Jupiter could put the planet Mercury on a collision course with Earth.
The findings indicate that the solar system is not as stable as previously thought and that Mercury is susceptible to being pulled around on its orbit. This could lead to one of four scenarios:
Scenario 1: Mercury will crash into the Sun
Scenario 2: Mercury will be ejected from the solar system altogether
Scenario 3: Mercury will crash into Venus
Scenario 4: Worst-case-scenario, Mercury will crash into Earth.
Any such collision would spell the end for pretty much everything on the planet. The last time such a collision occurred the resulting debris formed the Moon. BUT, don’t start worrying just yet. There's only about a 1% chance that any of this will happen before the Sun becomes a red giant billions of years from now (and destroys life on Earth anyway).Three separate groups of scientists have used different computer simulations to... more

Does Al Gore know about this?
While the former vice president is leading the charge for drastically changing the way humans do business in a bid to avert catastrophic, man-made global warming, scientists reported today there is noticeable climate change taking place on Jupiter, too.
The news follows reports as far back as three years ago that ice caps on Mars are also retreating much as some of the ice in the Earth's Arctic circle.
There's one striking difference between Earth and the other two planets, however. Neither Jupiter or Mars has any people – and no artificial activity creating so-called "greenhouse gases" like carbon dioxide.
Increased turbulence and storms first observed on Jupiter more than two years ago are still raging, according to astronomers from the University of California, Berkeley, and the W. M. Keck Observatory in Hawaii, who snapped high-resolution pictures of the planet earlier this month.
Captured with NASA's Hubble Space Telescope (HST) and the 10-meter Keck II telescope, this so-called "major upheaval" on Jupiter involves stunning changes in the planet's atmosphere, said lead astronomer Imke de Pater, professor of astronomy at UC Berkeley.

With the discovery of a fifth planet orbiting the star 55 Cancri, a team of scientists including SF State astronomers are one step closer to demonstrating that planets capable of sustaining life as we know it may exist beyond our own solar system. Assistant Professor of Astronomy Debra Fischer and Adjunct Professor Geoffrey Marcy discussed the planet hunting team's newest findings at a November 6 teleconference hosted by the National Aeronautic and Space Administration (NASA) Jet Propulsion Laboratory. A paper on the topic authored by Fischer, Marcy and colleagues was accepted for publication in Astrophysical Journal.With the discovery of a fifth planet orbiting the star 55 Cancri, a team of scientists... more
