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.
A mission that would sample plumes of gas shooting off of Jovian moon Europa appears to remain on track for a 2022 launch, after a meeting of the Commerce, Justice, and Science (CJS) subcommittee in which Republican Congressman John Culberson shared unreleased scientific results with his colleagues. The new paper…
Jupiter’s moon Europa features a warm subterranean ocean covered in ice. For years, scientists have wondered if certain surface features are the result of plate tectonics, which, if true, would make Europa the only known place in the Solar System other than Earth to experience large, subduction-driven quakes. What’s…
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.
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…
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 million miles from Earth. On February 7th, that team delivered their first report to NASA, detailing their recommendations for that…
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…
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…
Europa, Jupiter’s watery ice-moon, has long attracted attention as a possible site for someday finding life. Now, a new analysis shows that its oceans may be even closer to our own than we knew.
In a few billion years, the oceans will boil away and the atmosphere will burn up as our sun expands into a red giant. It’ll be game-over for life on Earth, but in the outer solar system, the party will just be getting started. Europa and Enceladus will melt into ocean moons, offering a refuge for any post humanoid…
Europa takes a simple question and makes it a challenge: Which of these are frying pans, and which is Jupiter’s moon? Eight of these are of cookware, and one is of a planetary object. How can this be so tricky?!
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 gotten 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…
Curious about how life got started on Earth 3.8 billion years ago? Here’s a thought: Why not recreate ancient hydrothermal vents in the lab, and see if they produce enough juice to power a lightbulb? That, at least, is what a bunch of scientists at the Jet Propulsion Lab decided to do—and the electrifying results are…
The search for life in the Solar System is about the hunt for water. Wherever we find liquid water on Earth, we find life. I’m talking everywhere. In the most briny, salty pools in Antarctica, in the hottest hot springs in Yellowstone, under glaciers, and kilometers deep underground.
In the last week, Venus and Jupiter were at their conjunction, and photographer Adam Tomaszewski took this fantastic picture of the pair. Look closely, and you can see Io, Europa, Ganymede, and Callisto orbiting Jupiter.
The allure of a warm, liquid ocean beneath Europa’s icy surface has inspired science fiction and real NASA missions alike. But if and when we get around to extraterrestrial oceanography, what will our undersea explorers look like?
A mission to study Europa in detail has cleared its first major review, and will soon be in planning stages. If all goes well, we’ll be headed to the Jovian moon in the 2020s, where we’ll gain new insights into active planetary bodies.
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…
Europa, the icy moon of Jupiter, is a favourite target for everyone from serious exobiologists to optimistic science fiction authors as a likely setting to find alien life in our solar system. Today, NASA announced the nine instruments that will be on-board the next robotic explorer to investigate the enigmatic world.
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 color may come from sea salt—the same stuff in our…
