Underwater casino slot online halo69 snow on Earth could aid in the search for life beyond our planet by shedding light on the alien nature of Jupiter’s icy moon, Europa.
Europa’s vast casino slot online subsurface ocean is considered to be one of the most promising locations in our Solar System when it comes to the hunt for extraterrestrial life. However, this salty, pitch-black realm is locked away beneath a dense shell of water ice that is estimated to be a staggering 10 – 15 miles thick.
Thankfully the casino slot online world-spanning natural barrier has done little to dissuade NASA from planning an ambitious multi-billion dollar mission to visit the moon. Enter the Europa Clipper.
The casino slot online cutting-edge spacecraft is slated to launch in October 2024 atop a SpaceX Falcon Heavy rocket, and will then spend roughly five and a half years in interplanetary space before finally arriving at Jupiter in April 2030.
After rendezvousing with casino slot online Jupiter, the spacecraft will carry out numerous close proximity flybys of Europa. During this time it will probe the moon with a suite of scientific instruments ranging from cameras and spectrometers to ice-penetrating radar, hunting for clues that Europa could be habitable.
The casino slot online scientific community’s understanding of the makeup of Europa’s ice shell will make a significant difference in how they interpret the data collected by the future spacecraft.
In order to better understand casino slot online Europa, a team of scientists led by Natalie Wolfenbarger of the University of Texas at Austin turned to one of the most alien environments on Earth — the frigid ocean beneath the ice shelves of Antarctica.
In this casino slot online place — where the temperature, pressure and composition is thought to be similar to that of Europa’s ocean – researchers have observed snow forming underwater.
These flakes then drift upward to gather casino slot online on the underneath of the shelf, where it adds to its already monumental mass and creates a strange upside down landscape of peaks of gorges.
The casino slot online team behind the new research believe that a similar process may be at work in the subsurface ocean realm of Europa, and that, by examining it, they can gain a greater understanding of what the thick outer shell is made of.
The casino slot online authors of the study — which was published in the scientific journal Astrobiology — analyzed two distinct methods by which liquid is known to transform into ice underwater. The first — known as frazil ice — sees flakes crystalize in a supercooled column of water. The second type of ice, known as congelation ice essentially grows directly from the bottom of the ice shelf.
Vitally, both of casino slot online these processes create ice that has a lower salt content than seawater. If the same were true on Europa, this would mean that the gigantic crust is much purer than previously thought.
Speaking to casino slot online IGN, Wolfenbarger explained that this is good news for scientists hoping to peer through the moon’s crust to observe the ocean-ice boundary using the instruments aboard the Europa Clipper.
Salt, when trapped in casino slot online ice, can heighten the overall electrical conductivity of the material, making it harder for radar instruments to penetrate deep beneath the surface. The presence of salt also encourages the formation of brine, which would lower the signal strength of the radar.
The casino slot online salty study could also alter the scientific community’s understanding of some of the key characteristics of the icy moon, including the nature of the tectonic activity that deforms the icy crust, and the manner by which heat transfers throughout the enormous structure.
