Discussion Overview

The discussion revolves around a mysterious blue band observed in Jupiter's atmosphere, particularly along the South Equatorial Belt. Participants explore potential causes for this phenomenon, including past events like the Shoemaker-Levy comet impact and the implications of satellite activity. The conversation touches on observational reports and the nature of atmospheric disturbances on Jupiter.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • Some participants describe a bluish streak in Jupiter's clouds, noting its unusual appearance and potential significance.
  • There are suggestions that the blue band could be related to the Shoemaker-Levy comet impact or satellite activity, with varying opinions on the plausibility of these connections.
  • One participant questions whether Jupiter could be "firing up" to become a new sun, prompting discussions about the theoretical implications of such an event.
  • Another participant argues against the idea of Jupiter becoming a sun, stating that it would require a significant increase in mass to sustain fusion, which would have catastrophic effects on Earth.
  • Some comments reflect skepticism about media exaggeration regarding the phenomenon, while others express curiosity and a desire for more information.
  • There are humorous exchanges and references to popular culture, including mentions of the film "2001: A Space Odyssey," which contribute to the lighthearted nature of the discussion.

Areas of Agreement / Disagreement

Participants express a range of views regarding the cause of the blue band, with no consensus reached on its origin or implications. Some ideas are challenged or refined, but disagreements persist regarding the potential for Jupiter to become a sun and the significance of the observed phenomenon.

Contextual Notes

Participants reference various observational sources and past events, but the discussion lacks definitive conclusions or resolutions regarding the nature of the blue band and its causes.

An Amazing Disturbance In Jupiter's Clouds...

It is a very elongated, bluish streak that runs along the interface of the dark South Equatorial Belt.

The first hint that that something unusual was taking place in the cloudy Jovian atmosphere came from Spanish amateur when he reported that a small, bicolored feature was formingt in the Southern Hemisphere a little over2 weeks ago. NOW, this disturbance has stretched, what looks like, right around the planet![interview in RM format included]

Jupiter going blue

I'm amazed to see what is going on on Jupiter.. Talking with others it was said maybe both events (Shoemaker Levey comet) And sending sending a satellite to it's death loaded with plutonium energy on the planet...

Another guy said that it just be fireing up to be a new sun.. Thats would be different to see in the night sky..

Anyone have a thought?

What happined to the big dark spot? It dissapeared?

SL9 hit at much lower latitude several years ago and that satellite had several orders of magnitude less kinetic energy than SL9. As for the Pu going critical due to the pressure of the atmosphere... no.


The great red spot is on the other side of the planet in that photo.

Yes, it's always interesting when something unusual happens; however "[a]lthough Jupiter has, in the past, produced some unusual upper cloud features, nothing like this has ever been seen before!", well, if you live in the heaven on Earth which is the mid-north coast (of the state of New South Wales) in Australia, I guess the ABC (not to be confused with the ABC) journos felt it was OK to exaggerate somewhat to excite the locals. (Little did they consider beady-eyed folk from Oregon, where it's always raining, who scour the internet for juicy morsels :wink:)

More about Jupiter, in case you were too afraid to ask ...

All things happin for a reason.. Even on Jupiter

Russ your thoughts are not as you think it may seem to you.. Did you see where the dark spot came into view once it came in view? Jump into a boat and see where the boat ends up on any normal lake.. It always moves to a new direction.. All it takes is ripples to start a new motion in a new attitude in travel..

whoa whoa whoa.. okay, first off.. I'm waay out of my league around here but I still enjoy perusing these forums and trying to learn a thing or two. I came across this and can't help but ask for abit of elaboration. Could this theoretically be possible? If so, wouldn't that be abit catastrophic for Earth?

No and No. You've seen the movie 2010, right (if not, I highly recommend it)?
 
"My God! It's full of stars!"
 
Pssss, Njorl, that's 2001.

Fear not, Jupiter is far too small to become a sun. It's mass would have to increase 80x in order to sustain a fusion reaction like a star. If Jupiter's mass were somehow to suddenly increase 80x, then yeah, that would mess with Earth's orbit and the new sunlight would heat things up 'round here.

D'oh!

"Something's going to happen."
"What?"
"Something very special."

whew! okay I'll stop worrying now. :-p

ummm.. I saw 2001 many a year ago.. but alas I was too young and it went *whoosh*, straight over my head. Perhaps I'll give it another try.

The first time I saw 2001 I watched it on a 9" black and white TV. I don't recommend it that way.

I just noticed the true title of this story. I thought it said Blues Band...that changes everything. :eek:
