An Ocean Beyond Earth: Europa Awaits

It's no secret that Earth's┬ocean is┬filled with life, much of it still a mystery or totally unknown to science. But what about the ocean on other worlds? I'm not talking┬about sci-fi planets or suspected alien Earths around other stars, either, but right here in our own solar system, where an ocean even deeper than ours […]

NASA's Remastered View of Europa is the Best Yet

Europa, Jupiter's sixth-closest moon, has long been a source of fascination and wonder for astronomers. Not only is it unique amongst its Jovian peers for having a smooth, ice-covered surface, but it is believed that warm, ocean waters exist beneath that crust – which also makes it a strong candidate for extra-terrestrial life. And now, […]

Visible in even modest backyard telescopes, the GRS has been churning away for┬at least several hundred years. But, based on recent analysis of data gathered by the Cassini spacecraft […]

Jupiter's Great Red Spot Gets Its Color From Sunlight, Study Suggests

If it weren't for the Sun, Jupiter's Great Red Spot would be a much blander feature on the gas giant, a new study reveals. This stands apart from what most scientists think about why for why the spot looks so colorful: that there are features in the clouds that give it its distinctive shade. The […]

Habitable Moons at the Ice Line?

Those of us who love astrobiology get really worked up about the lack of Earth-sized exoplanets found at Earth-like distances from their stars. All we want, we who hope for lots of extraterrestrial life, is a bunch of Earth-like planets doing Earth-like things so we can feel better about the odds for lots of Earth-like life in the universe.

Just In Time for Halloween: Jupiter Gets a Giant Cyclops Eye!

Halloween is just around the corner. And in what appears to be an act of cosmic convergence, Hubble captured a spooky image of Jupiter staring back at us with a cyclops eye! While this is merely a convenient illusion caused by the passage of Ganymede in front of Jupiter – something it does on a […]
