Spacecraft May Have Flown Right Through a Plume of Water on Jupiter’s Moon Europa

Sometimes, scientists have the answers all along—they just don’t think to ask the question. For example, it appears that in 1997, the Galileo orbiter flew through a jet of water shooting out from Jupiter’s moon Europa without even trying. Read More >>

Massive Lava Waves Detected on Jupiter’s Moon Io

Io is the closest thing we have to hell in our Solar System, a Jovian moon that features hundreds of active volcanoes and expansive lakes filled with lava. New observations suggests that the largest of these lakes, Loki Patera, produces enormous waves that repeatedly flow around the molten surface. Read More >>

An Alien Hunter on the Risks and Rewards of Landing on Europa

On Friday, February 10th, NASA announced that a team of 21 scientists had delivered their first report on a lander mission to explore the possibility of life on Jupiter’s icy moon Europa. The NASA-employed Science Definition Team (SDT) recommended that NASA send a probe as soon as 2031, about a decade after an already-planned Europa flyby mission. Read More >>

NASA Plans to Drill Toward Europa’s Crust In Search of Life

Since early 2016, a NASA-employed Science Definition Team (SDT) of 21 researchers has been crafting a plan to send a robotic probe to Europa, an icy moon of Jupiter, located over 390,000 miles from Earth. On 7th February, that team delivered their first report to NASA, detailing their recommendations for that future mission, which will search for life by drilling toward the subterranean ocean scientists strongly suspect to exist beneath the icy moon’s surface. The team hopes to launch as soon as 2031. Read More >>

Another One of Saturn’s Moons May Have a Global Ocean

The evidence is mounting that our solar system is rife with oceans. Last week, scientists reported that Pluto could have an insanely deep liquid water swimming pool beneath its surface, and on Monday, NASA revealed new evidence for geyser activity on icy Europa. Now, another frozen moon is poised to join the club of outer space scuba retreats: Dione. Read More >>

Hubble Discovers New Evidence of Water Geysers on Europa

Jupiter’s moon Europa is on the shortlist of places we might discover alien life in our solar system. And today, the prospects for finding extraterrestrial microbes on this little ice moon got a lot better, when NASA unveiled new evidence for water geysers near Europa’s south pole. The discovery strengthens the case for a geothermally-heated, subsurface ocean. Read More >>

Europa is Even More Earth-Like Than We Suspected

Europa, Jupiter’s watery ice-moon, has long attracted attention as a possible site for finding life. Now, a new analysis shows that its oceans may be even closer to our own than we knew. Read More >>

Does Europa Have an Ocean?

Europa’s fabled ocean has inspired science fiction movies and actual space missions alike — and yet we aren’t even sure it exists. NASA has grown so curious, it recently greenlit a mission to Europa that’ll hopefully settle the matter once and for all. And the space agency has just produced an excellent video explaining why we should care. Read More >>

NASA: We are Going to Europa

Jupiter’s moon Europa is covered in a thick layer of constantly shifting ice which appears to be floating atop a deep, warm ocean. Scientists have long suggested that it’s the most likely place that life might have evolved beyond Earth. And now, at last, NASA has confirmed our first mission to Europa has entered the development phase. Read More >>

The Mysterious Bands Crisscrossing Jupiter’s Moon Europa May Be Sea Salt

The icy white surface of Jupiter’s moon Europa is streaked in yellow-brown, cracks made by the ocean below. These dark streaks hint at the chemical composition of the ocean, which is one of the top places to search for alien life. Here’s encouraging news: The dark colour may come from sea salt — as in, the same stuff in our oceans. Read More >>

Europa’s Icy Surface Looks Like Cracked Glass

This is a false-colour image of Europa, Jupiter’s fourth-largest moon, a water-covered giant with the smoothest surface in the Solar System. And yet, I could still swear I’m looking at the end result of a football going through a stained-glass window. Read More >>

Europa Remastered: This ’90s Space Image Has Been Retouched by NASA

It's not just old rock albums that get remastered when technology moves on: this image of Jupiter's ice-covered moon, Europa, has just been given a revamp by scientists from NASA. Read More >>
