Io’s Volcanoes

Io looks a bit like a pale pizza, covered in weird splotches that turn put to be volcanoes, surrounded by the black of space.

It’s fascinating to me that we can peer up through our thick and whiriling sea of gasses above us that we call our atmosphere and peer into the far reaches of our solar system to capture images of Jupiter’s moons and their surface activity here from the surface of our own planet. 

Thanks to the amazing Phil Plait for the inspiration to look up today!

An amazing image of Io, Jupiter’s tortured hell-moon:

Yowza! All those blotches on it are volcanoes, many of which are active (Io is relentlessly squeezed by Jupiter’s immense tidal force, which create internal friction which melts the moon’s interior and cracks the outer layers, allowing that material to reach the surface). In fact the paper notes that the observations show some changes on the surface. The volcano Pele is the oddly shaped dark blob just below and to the right of center, surrounded by a red ring of erupted material. There are two volcanoes just to the right of it; the left one is Pillan Patera, and the scientists note that the red ring looks overlaid by newer lighter material right where Pillan sits. That’s likely from a powerful eruption that occurred in 2021.

Something Funny Happened On the Way to Teaching Earth Science

I wasn’t particularly sure how my teaching year would go this year. I knew I was teaching Physics and Physical Science. Both of those are right in my wheelhouse and I enjoy teaching both of those immensely, and I’m incredibly passionate about the topics in those subject areas. However, the big question was Earth Science (and teaching 6th grade, which I’ve never done for an entire year). 

Turns out, I fell in love with my 6th-grade classes and Earth Science has become something of a new passion of mine. I did not see that coming.

Lately, I’ve been reading books on geology and geologic time scales and catastrophic events and listening to audiobooks on plate tectonics and seabed composition, and subscribing to Apple News topics about geophysics, and hydrology… weird.

I’ve always been somewhat interested in Earth Science adjacent topics, obviously. I remember enjoying my own time in an Earth Science class in 8th grade and then in basic geology in college. But having to plan out an entire year and helping to motivate 11, 12, and 13-year-olds to get interested in the water cycle helped me realize just how incredible the topic can be.

Reminding young people that Earth, as we know it, is an incredibly and rapidly ever-changing system and not some static immovable rock where things have always been the same has been such a joy and a privilege. Plus, it’s a humbling reminder of our own human place in the Creation and the Cosmos!

I can’t wait to explore some of these topics with our Upper Schoolers next year in our new Earth & Space Science class that we’re launching next year at TSA!
