Planetary scientists suspect Jupiter's cracked, ice-blanketed moon Europa harbors a particularly voluminous sea, some 40 to 100 miles deep. Now, for just the third time ever, a spacecraft flew by the icy moon, swooping only 219 miles from Europa's surface. The other two flybys happened over two decades ago. NASA's Juno spacecraft, famous for its dazzling views of Jupiter's roiling clouds, captured some of the clearest, high-resolution images of Europa ever seen, which you can see below.

But that's not all.Juno's specialized instruments penetrated through parts of Europa's ice, which is some 10 to 15 miles thick. This unprecedented data will be parsed by NASA and other researchers to reveal what lies in the icy shell, like potential pockets of water. So stay tuned, in the coming months, for what NASA found.

"Europa is of incredible interest — a high priority target for science," Scott Bolton, the Juno mission's principle investigator, told Mashable.

Life thrives in Earth's salty oceans. There's certainly no evidence of life on Europa, but it could harbor environments that host life (as we know it). In other words, this moon could be a "habitable" world in space.

"It's one of few places that potentially has the conditions for habitability," Bolton emphasized. Bolton works at the Southwest Research Institute, a research organization that often partners with NASA.

NASA released its first official image from this close flyby on Sept. 29. It shows Europa's wild, icy, cracked crust in a region near the equator dubbed "Annwn Regio." The terrain is rugged and has been repeatedly fractured apart. Slushy ice, perhaps supplied from relatively warmer regions below, may have filled these cracks.

"It’s very early in the process, but by all indications Juno’s flyby of Europa was a great success," Bolton said in a statement when the first image was released. "This first picture is just a glimpse of the remarkable new science to come from Juno’s entire suite of instruments and sensorsthat acquired data as we skimmed over the moon’s icy crust."

Then, on Oct. 5, NASA released the highest resolution image ever snapped by the Juno spacecraft. The image below (encompassing an area 93 miles across and 125 miles high) shows an area crisscrossed with grooves and ridges. Of note are the peculiar darker blotches. "Near the upper right of the image, as well as just to the right and below center, are dark stains possibly linked to something from below erupting onto the surface," writes NASA. "Below center and to the right is a surface feature that recalls a musical quarter note, measuring 42 miles (67 kilometers) north-south by 23 miles (37 kilometers) east-west."

What's more, all of the imagery captured by Juno is made available for the public — more specifically "citizen scientists" with impressive photo skills and a keen interest in astronomy — to process. Just below is an image tweeted out by professional imaging processor Jason Terry. And under that is a "raw" unprocessed Europa image that NASA posted online.

These new close-up images are like a treasure trove for planetary scientists. Before, they only had data from two flybys from the Galileo spacecraft, years ago. Now there's a third load of data. "It's a huge, giant leap," Bolton said.

What comes next, besides more image releases, will be observations from Juno's microwave radiometer, an instrument that can penetrate Europa's thick ice. What's down there? There could be relatively warmer regions harboring cavities full of water, noted Bolton.

"Is there life elsewhere?"

"I suspect if there's waterit'll stick out like a sore thumb to us," he said.

The question that looms large is whether any life might dwell in this water, or in the seas sloshing under the ice. We don't know. We're far from any answers. But that's one of the enticing elements of exploration.

"One of the goals of exploring the solar system and universe is to see if we're alone," Bolton told Mashable. "Is there life elsewhere?"

This story will be updated with more Europa images as they're released.
