Titanic volcanic eruption seen on Io
14:50 14 November 02

A titanic volcanic eruption has been spotted on the surface of Jupiter's volatile moon Io using a telescope back on Earth. Astronomers believe it to be the most powerful eruption ever witnessed in the entire Solar System.... [see link for photos].

Guess that's out now.

I believe Aurthur C. Clarke was writing about Europa when he wrote that line! Indeed he was, and for good reason. Europa could very well contain liquid water under the ice/rock sheet that coveres most (if not all) of its surface. If Jupiter had a bit more mass, it could generate enough internal heat to initiate nuclear reactions, and a star would be born. If I remember correctly, Clarke hypothesized that Europa's ice sheets would then melt, and a very earth-like (but geographically flat) planet would emerge.

Neat pictures! Just how big is Io anyway (Compared to our own moon)?

Send this "flub" to Karl Rove.

This can be used to cancel out atmospherics such as heat waves. Cool. But heat waves? I just read an article on it - it reacts in the ms. range.

There was a time when there was a big debate in the scientific community as to whether the craters on the moon were caused primarily by volcanoes or by impacts.
It is very difficult to tell just by observation when you don't have detailed images.
An ancient Greek astronomer (I've forgotten which) reported seeing a bright flash on the limb of the moon. Some historian/astronomers believe that this was an observation of the impact of the object that created the Copernicus crater (one of the youngest on the moon's surface).
It is not unresaonable to think an astronomer would use Occam's razor and postulate that these are images of a volcano. Perhaps it is more of a stretch to think they might have caught images of an actual impact. It would especialy be true if the astronomer had not heard of the ancient observation.
Shoemaker-Levy proved that we can see the effects of impacts on a planetary object.
It's not in the realm of the impossible that they captured an impact in progress.

Thanks for the info! Very interesting, I can now "see" the size of the eruption.
Thanks again,

I was looking at those tables again, it rotates as fast as it orbits the planet? One day! WOW. Sounds like an amusement park ride I was on last summer =-)
Looking up the answer to your question was an education for me also... the universe sure is an amazing creation.

Anything you work on?

I used to read this stuff way back when. Clarke wrote a lot about the solar syatem and space in general that was based on known facts of the time. He was also the first known to envision our fleet of geostationary satellites. I have probably read almost every word he has written, and still have some of the books around. The comment about Eoropa was, I believe, from the prologue chapter of "2010: Odyssey II". It was a great tale that was ruined by Hollywood.
Another great author from the past, Heinlein (sp?), wrote of earth people doing something to Jupiter that started the nuclear reaction and turned it into a second sun, generating heat that warmed Jupiter's moons, and they colonized Ganymede, I think. Today, Europa is regarded as more Earth like.
Off topic, but I read most of Heinlein way back when I was in high school, in the '70s. They were fascinating because the technology used to do all those great things was already 20-30 years old when I read them. The electronics, computers, etc. had vacuum tubes. I've never seen a computing device that used tubes but I understand they were rather large. Yet people were getting them to escape velocity and flying around in space with them. Also, he didn't utilize things like warp speed or hyperspace, so space travel took a long time and involved the whole family.

So next time, I'll ask for something really tough...a comparison between Io and a '73 Buick Le Sabre!
I agree the universe is an amazing place... Maybe I'll visit it one day! :o)

hell with that...look at that feedback link to find out all you wanted to know about hamster's gonads! those whacky scientists.

Nope. But this is cool! Thanks for the ping. :-)
