Many thunderstorms in Saturn's atmosphere could be driving the gas giant's vast polar cyclones, according to new simulations inspired by observations from NASA's Cassini spacecraft.
Although our solar system doesn't contain gas giants with thick atmospheres enriched with helium, observations by NASA's Spitzer Space Telescope suggests the galaxy may be strewn with these planetary oddities.
As NASA's New Horizons spacecraft blasts closer to Pluto at a pace of 750,000 miles per day, increasingly detailed images are beginning to come our way.
The stellar runts of the galaxy probably aren't so great for nurturing Earth-like worlds, say scientists running new simulations of the formation of planets around a variety of stars.
A robotic spacecraft that circled Mercury detected magnetized rocks, evidence that planet’s still-roiling, liquid metal core likely spawned a global magnetic field as far back as about 3.8 billion years ago.
The erupting geysers on Saturn's Enceladus may not be geysers at all, they might just seem to appear when viewed from certain angles.
The primordial planet believed to have smashed into baby Earth, creating a cloud of debris that eventually formed into the moon, was chemically a near-match to Earth.
When it comes to making planets as big as Jupiter, Mother Nature has kept her recipe secret. But scientists believe they have finally cracked the mystery.
