@maperal the colors are exaggerated and show more of the infrared light, but it is close to what you'd see if you were flying above!

Good morning! While I let my #coffee cool, I thought I'd kick off a thread describing my area of #astrophysics / #astronomy #research which I'll add to throughout the day. At the end, I'll mention how my work relates to what I think is the most amazing #fact about our time and place in the #universe.

Follow along and feel free to ask questions! I will try my best to get to them all!

Now... On to Tidal Dynamics... 🌎🌔

You might have heard that the #tides that cause #Earth's #oceans to rise and fall twice each day are caused by our Moon, but did you know that the same #Physics has the power to flex & churn other worlds to the point of melting?

Here is #Jupiter's moon #Io captured in the early 2000s by the Galileo spacecraft. It's surface looks really odd, so many different yellows, reds, and oranges. In the image a strange blue plume gives us a hint to what is going on...

#Volcanoes! 🌋and lots of them!
