MAIN POINTS

Loose Six or Seven Year Itch
"Every six or seven years, we found examples of observations when the equatorial clouds had vanished completely, allowing us to see deeper into Jupiter's churning atmosphere. These cloud-clearing disturbances left the equator looking very bright in the infrared, and dark brownish in visible light. These disturbances lasted for 12-18 months, and we saw spectacular examples in 1973, 1979, 1992, 1999 and 2006."

“It seems that this six-seven-year pattern isn't perfect, and sometimes we don't see a complete cloud-clearing disturbance."

“...we expect to see a new event very soon, perhaps as early as next year."”

Moons of the Solar System
JOVIAN MOONS of MYSTERY

The coolest moons in our solar system are those active moons of Jupiter, active from the gravity-squeezings given to them by Jupiter's massive mass, as they rotate around it.

Io has the suflur squeezed out of it, while Europa  gets the water squeezed out of it... Does this heat provide energy for more than fountains of materials squirting out into space, providing the energy for lite itself?

Support Tahoe to Whitney

The Tahoe to Whitney Trail Guide and Magazine are walked, written, funded, and supported by my efforts, with the help of kindred spirits and my sister.

We offer valuable Trail Guide, Skills, Weather, News and Analysis.

My goal is to get you out to see your natural and social potential. Help me keep this unique resource accessible and expanding towards its potential. We've a lot of miles to cover ahead...

I NEED HELP!
If you feel these efforts are valuable, I'm cordially inviting you to support them, here:

 

 

I am currently working towards publishing the completed guide between Tahoe & Yosemite as an e-book, while converting this "blog" to a fine magazine format. You will like the results! Help Tahoe to Whitney reach its potential!
