Solar System Kicked Out Extra Planet

Early ejection may have helped Earth survive

(Newser) - Thank your lucky stars that our solar system was only big enough for eight planets. Apparently a ninth one—and a gas giant, no less—was nudged out billions of years ago and made room for Earth to survive. In computer simulations of our solar system's evolution, Colorado scientist...

Saturn Moon May Hide Underground Ocean

Salt water ice spewing out from under the surface

(Newser) - Saturn’s moon Enceladus is spewing what appears to be chunks of ice composed of salt-water vapor out of fractures in its southern pole, leading scientists to believe there may be a massive ocean lurking beneath its surface.

'Ice Volcanoes' Spotted on Titan

'We finally have some proof that Titan is an active world'

(Newser) - Scientists say they've seen the clearest evidence yet that volcanoes sprout from Titan's icy surface, though a probe may need to land on the Saturn moon should they want to know exactly what the "cryovolcanoes" are spewing out. Three peaks and pits spotted by the Cassini probe are "...

Tsunamis Spotted in Saturn's Rings

Rings may be remnants of smashed icy moon

(Newser) - Mile-high tsunamis of icy particles are endlessly rippling around Saturn's rings, scientists told the American Astronomical Society's Division for Planetary Science meeting this week. Astronomers, using data from NASA's Cassini probe, believe the waves, which move up to 800 feet per day, are caused when gravity from the colossal moon...

Scientists Think Something Is Living on Saturn Moon

Primitive lifeform may explain absence of hydrogen

(Newser) - Something is sucking up hydrogen on one of Saturn's moons and NASA scientists believe it could be alive. Data from the Cassini probe suggests there is less hydrogen and acetylene on Titan's surface than scientists expected, a phenomenon that could be explained by the existence of primitive, methane-based lifeforms, the...
