Do You Know Your Patronus?

Pottermore has added a new quiz. In addition to the Hogwarts and Ilvermorny sorting, they now have a quiz to determine what your Patronus is. I took it and recorded myself as I did it. Find out what mine is!

Just what is this? Well, it’s Europa superimposed on an image of Europa taken by the Hubble Space Telescope. See that white stuff coming from the bottom left? That seems so similar to what we’ve seen from Enceladus. That’s a possible water plume!

So, what does this mean? It means that water is making it to the surface of Europa. This also means that we may have a much easier time accessing the water than we thought. We already have an extremely good idea about the internal structure of Europa, which likely includes a very deep liquid water ocean. Europa is one of the best candidates for life in the solar system, and with upcoming missions to Europa and the other icy moons of Jupiter coming soon, we’ll have an excellent opportunity to know what the composition of this water is. It’s suspected to be salty, but how salty is it? And does it support life?

This is very exciting. What do you think?
