New study traces Io’s volcanic tides

Hundreds of volcanoes pockmark the surface of Io, the third largest of Jupiter’s 78 known moons, and the only body in our solar system other than Earth where widespread volcanism can be observed. A new study finds Io’s most powerful, persistent volcano, Loki Patera, brightens on a similar timescale to slight perturbations in Io’s orbit caused by Jupiter’s other moons, which repeat on an approximately 500-Earth-day cycle.

NASA Solves How a Jupiter Jet Stream Shifts into Reverse

Speeding through the atmosphere high above Jupiter’s equator is an east–west jet stream that reverses course on a schedule almost as predictable as a Tokyo train’s. Now, a NASA-led team has identified which type of wave forces this jet to change direction.

Odd behavior of Jovian moon dust could inform future space missions, search for life

New research into the movements of dust around Jupiter’s four largest moons could help scientists searching for life in our solar system, according to a new study. This moon dust around Jupiter could give scientists clues about the composition of the surface of its satellites.

Hubble Images of Jupiters “Northern Lights” are Amazing!

Jupiter has a MUCH stronger magnetic field than Earth does, and the Aurora’s it produces have been known about for a while, but this image above from Hubble though is one of the most incredible I’ve seen! More from NASA/Hubble HERE. Next week a new spacecraft named JUNO will go into orbit around Jupiter, and we will learn a lot more about the large gas giant. More on the JUNO …

The Hubble Telescope View of Jupiter is Amazing

From NASA: New imagery from NASA’s Hubble Space Telescope is revealing details never before seen on Jupiter. High-resolution maps and spinning globes (rendered in the 4k Ultra HD format) are the first products to come from a program to study the solar system’s outer planets each year using Hubble. The observations are designed to capture a broad range of features, including winds, clouds, storms and atmospheric chemistry. These annual studies …

Don’t Miss This June Sky Show

Kelly Beatty is my “go to guy” for astronomy questions, and he’s been kind enough to come to the AMS Conference on Broadcast Meteorology for years ( he was an invited talk again this year by the AMS Committee on Station Science of which  I’m chair). Kelly writes for Sky and Telescope, and he has a cool podcast about a real sky show later this month. He told us about …
