Life on an Icy Moon

Jupiter’s moon Europa is the size of the Earth’s moon, and yet it holds more than twice as much water as all of Earth’s oceans combined. Europa’s salty ocean covers the entire surface, and the crust is completely frozen over because the moon is 780,000,000 km from the sun and has an average temperature of -160 degrees Celsius. The icy moon’s orbit is eccentric, orbiting in an oval instead of a circle, and so Jupiter’s enormous gravitational pull constantly squeezes and stretches the moon, creating constant motion and likely the surface cracks too. This tidal heating generates warmth, which creates a significant chance that this distant ocean is harboring life. Radiation from Jupiter’s magnetosphere could destroy life at shallow depths, but new research suggests that there’s oxygen available in the subsurface ocean that could support oxygen-based metabolic processes. Scientists must now determine how deep such organisms must hide in order to avoid radiation, and therefore how deep we need to go to find them. The icy crust might be hundreds of metres or even kilometres thick, and so sending a probe through the surface would be difficult, but we have to try, because Europa is one of the best potential sources for extraterrestrial life in the solar system.

Yep haha

All my high school classmates are getting married and/or having kids.....then here I am with my sugar gliders.

Brilliant

UM... NEED!!

Planet Ring Set

I recently got to view this through my very own telescope, super exciting!!
