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.
NASA on Tuesday selected nine science instruments it believes will best address the burning question about whether Jupiter’s ocean-bearing moon Europa has indications of life.
Jupiter and our moon will perform a celestial dance tonight, clear skies willing.
Salt from an underground sea on Jupiter’s moon Europa may be seeping onto the surface, then darkening as it is exposed to radiation.
The 'elusive planet' Mercury kicks off the month in the midst of its best evening apparition of 2015. But Mercury isn't the only visible planet this month.
