Shocker from Jupiter:  Great Red Spot is shrinking

posted, by Staff -- May 15, 2014

Historic observations as far back as the late 1800s [2] gauged this turbulent spot to span about 41,000 kilometers at its widest point — wide enough to fit three Earths comfortably side by side. In 1979 and 1980 the NASA Voyager fly-bys measured the spot at a shrunken 23,335 kilometers across. Now, Hubble has spied this feature to be smaller than ever before [16,500 kilometers across].

“In our new observations it is apparent that very small eddies are feeding into the storm,” said Simon. “We hypothesized that these may be responsible for the accelerated change by altering the internal dynamics of the Great Red Spot.”

Simon’s team plan to study the motions of these eddies, and also the internal dynamics of the spot, to determine how the stormy vortex is fed with or sapped of momentum.

Photographs from the Hubble Space Telescope clearly show that Jupiter's Great Red Spot is shrinking. The images, spanning the course of 20 years, indicate that the spot - which is actually a massive storm - is narrowing faster than ever before. Astronomers don't know why the spot is shrinking, or what will happen next.

Now if only the Republicans can figure out how to perform that "disappearing trick" on -- their Fear of Taxes, their Fear of Science, their Fear of 'Losing their Country' ...

"The Eye Of Jupiter" (or "The Great Red Spot") is a persistent anticyclonic storm 22° south of Jupiter's equator; Earth observations establish a minimum storm lifetime of 182 years to possibly 347 years. I also composed the music for this video -- a five minute track of the same name. Thanks for watching!

Better study up, Horatio. There's a new Exam, nearly everyday, in this thing we call Life.

More Tagging tips:

A tag is a way to search for this diary. If someone is searching for "Barack Obama," is this a diary they'd be trying to find?

Use a person's full name, without any title. Senator Obama may become President Obama, and Michelle Obama might run for office.

If your diary covers an election or elected official, use election tags, which are generally the state abbreviation followed by the office. CA-01 is the first district House seat. CA-Sen covers both senate races. NY-GOV covers the New York governor's race.

Tags do not compound: that is, "education reform" is a completely different tag from "education". A tag like "reform" alone is probably not meaningful.

Consider if one or more of these tags fits your diary: Civil Rights, Community, Congress, Culture, Economy, Education, Elections, Energy, Environment, Health Care, International, Labor, Law, Media, Meta, National Security, Science, Transportation, or White House. If your diary is specific to a state, consider adding the state (California, Texas, etc). Keep in mind, though, that there are many wonderful and important diaries that don't fit in any of these tags. Don't worry if yours doesn't.
