A new high-resolution image of Jupiter’s icy moon Europa shows that its surface is not covered with craters, but with what resembles highways, stretching for miles.

Europa is thought to be the most likely place in the solar system to find extraterrestrial life, but it’s aquatic rather than terrestrial.

NASA’s Juno mission captured the photo on Sept. 29 during a rare flyby that reached within about 256 miles of the Earth’s surface. The moon’s severely cracked ice crust” it’s incomprehensible.

“The image covers about 93 miles (150 kilometers) by 125 miles (200 kilometers) of Europa’s surface, with fine grooves and double ridges (pairs of long parallel lines that mark raised ice features). networks intersect,” says NASA.

“There are black smudges near the top right of the image, and just below the center, suggesting that something is squirting onto the surface from below.”

Social media commenters quickly began offering theories, with some citing the line as highway road mapother suggestions they are trucks left by something sliding on the ice, A few point out what they saw Five-pointed star in the photo.

NASA scientists also have theories.They speculate that the lines are spots on Europa’s surface. “I pulled away” And something dark “from beneath the surface” filled the cracks.

According to Juno Mission Principal Scientist Scott Bolton, “Many believe the cracks and ridges on/in the lunar ice crust indicate weak lines within the lunar ice crust.

The rift is “enhanced and exacerbated by the tides due to Jupiter’s gravitational pull,” he said.

Europa isA huge, salty liquid sea.” the topping 15 miles thick ice crust. temperature According to NASA, it ranges from -210 degrees Fahrenheit to -370 degrees Fahrenheit at the poles.

But deep-sea exploration on Earth has proven that even the most extreme places on Earth can find life. doing.

“This image unlocks an amazing level of detail in areas that were previously unimaged at such resolution and under such obvious lighting conditions,” said Juno’s head of the Stellar Reference Unit. Co-investigator Heidi Becker said.

“These features are of great interest. Understanding how they formed and how they are connected to Europa’s history will help us understand the internal and external processes that form the icy crust. will let us know about.”

Juno started “Full focus on Jupiter” However, expanding that investigation, the planet’s 4 largest satellitesamong which Europa is the smallest.

“In the early 2030s, NASA’s Europa Clipper spacecraft will arrive and attempt to answer these questions about Europa’s habitability. Data from the Juno flyby provides a preview of what that mission will reveal. ,” says NASA.
