Io: Jupiter’s Volcanic Moon

Posted on April 5, 2018 by natsastronomy

If you showed me a picture of Io, my first thought would not be that it is a moon. To me, it looks like a block of cheese, a little rotted in certain places. That is because it looks so different from our idea of a moon, or that is Earth’s moon. Earth’s moon is … Continue reading Io: Jupiter’s Volcanic Moon → Continue reading →

Volcanism on Io

Posted on April 4, 2017 by vmorehead0

From the four Galilean moons of Jupiter, Io stands out as having a great amount of volcanic activity.  Before it was observed via spacecraft, scientists believed all moons were cold and barren like Earth’s moon.  However, on March 8, 1979, Voyager 1 captured a mysterious plume rising from Io.  Scientists identified this as a volcanic eruption, which made Io … Continue reading Volcanism on Io Continue reading →

Jupiter’s Galilean Moons

Posted on April 10, 2016 by harperastronomyblog

Discovered by Galileo in 1610, Jupiter’s four largest moons are some of the most interesting worlds in our Solar System. “Volcanic Io”: Jupiter’s inner-most moon, Io, is the fourth largest moon in the solar system. It is also the most volcanically-active object in the Solar System, with over 400 active volcanoes. Large mountains cover its […] Continue reading →

Volcanic Io

Posted on April 9, 2016 by lindseynestor

Volcanoes are one of the coolest geographical features of Earth (in my opinion), but volcanoes outside of our world are even cooler. Jupiter’s moon Io is the most volcanically active world in our solar system – in other words, it is FULL of volcanic awesome-ness. Io’s volcanic activity produces HUGE volcanic plumes. To give some […] Continue reading →

Io

Posted on April 7, 2016 by lawlorsolarsystem

Io is Jupiter’s third largest moon. What is notable about Io is that it is the most geologically active body in the entire Solar System. It is extremely volcanic, and is the only body other than Earth that we  have observed with active volcanism. The volcanic activity occurs because Io is greatly affected by tides […] Continue reading →

Tidal Forces

Posted on February 15, 2016 by lindseynestor

As a person that has always been happiest by the ocean, I really enjoyed learning about tides and decided to do some further research into other effects and instances of tidal forces in our solar system. Just as the Moon causes tides on the Earth, Earth creates tidal forces acting on the Moon. This is […] Continue reading →

Io being squeezed

Posted on April 6, 2015 by lindenmuthadam

We all know that Jupiter exerts tremendous tidal squeezing on Io, but we need images to truly grasp the magnitude of this force. This image shows Io spewing a 200 mile high volcanic plume! For reference, that is greater than the distance from Nashville to Knoxville! It is baffling to think that tidal squeezing alone […] Continue reading →

The Galilean Moons

Posted on April 5, 2015 by oliviasn

When I went out observing on the 24th Avenue Parking Garage the other night, every astronomical object that I saw through the telescope amazed me, but Jupiter especially captured my attention. I had never viewed Jupiter through a telescope before, and on this beautiful and mostly clear night, I was able to clearly see not […] Continue reading →

Jupiter’s volcanic moon: Io

Posted on April 5, 2015 by bryancm1

Io sports a surface temperature well below zero (around -130 degrees C). This is heavily contrasted by the fact that Io is also the most volcanically active body in our solar system. It is known to have over 400 currently active volcanoes. If you weren’t yet convinced about the effects of tidal heating, think about […] Continue reading →

Io’s crazy volcanoes!

Posted on April 4, 2015 by karenagrebenc

photo from space.com So, we all know that Io is notoriously the volcanic moon of Jupiter, but apparently a couple of years ago it randomly got…MORE volcanic? According to this article, in August of 2013 three large eruptions occurred on Io.  To put it in perspective, this is the number of large eruptions that we […] Continue reading →
