*Interesting article about the already-observed decrease in the solar temperature, how it will impact global warming (decrease) and also help to determine how much of global warming is due to mankind's activities.

The sun is projected to return to normal levels by 2200.

I wonder whether the sun getting cooler and apparently less active over the next century or so will result in fewer solar flares?
If so, that would be a boon to human deep-space missions because of the lesser risk of harmful radiation. How fortuitous at this particular moment in time, as humanity contemplates sending colonists to Mars!
Maybe there is a God, after all.

*Frankly, I think the sun is simply being willful and naughty. Now that we've got all this cool technology and instrumentation to further study its coronal mass ejections, quakes, etc...NOW it is calming down. Like a pet who does spontaneous and funny things throughout the day, and who refuses to do anything but sit and stare the second a camera is pointed at it (even from around the corner of another room).

Hmmmmmm!

You're probably right, Cindy.
But while you can train a wilful cat or dog, what do you do about a recalcitrant star?!!

alokmohan · 2003-10-19 04:14:36

Cyndi can do it easily.King Canute did it.

Shaun Barrett · 2003-10-20 02:10:45

I thought King Canute failed.

Lakes on Titan??

*Get yer rods and tackle boxes out, fellas.

You catch it (and clean it); I'll fry it.

"These lakes would be made of a mix of methane and ethane. These are the two main components of natural gas on Earth, but at Titan's bitter-cold surface temperature
of ?179? Celsius, they are liquids. Titan's atmosphere is mostly nitrogen, like the Earth's, but methane is also a significant constituent. Scientists have speculated that the methane acts on Titan like water does on Earth, participating in a hydrological cycle to form clouds, rain, rivers, and seas."

P.S.: We've got to wait until 1/2005 until the Huygens probe is dropped onto Titan!

Mars, Phobos & Deimos w/11-inch telescope

*I have to point the mouse directly over the photo itself to get the names of the moons to appear as markers beside them(Deimos is a very faint dot -- you'll need the name marker!).

Gemstones found on Mars

Large quantities of a green mineral gemstone have been found on Mars.

Rocky outcrops of the mineral olivine were spotted by a space craft orbiting the planet.
On Earth, the mineral is known as peridot, a cheap gemstone used in jewellery.

Peridot is my birth stone.

Mars just keeps on givin!

Huge solar storm headed our way!!

A peek at a pre-supernova enviroment

"An x-ray-plus-optical composite image showing part of the Crescent Nebula's rim gives astronomers a look at a pre-supernova environment...In about a hundred thousand years, the massive star HD 192163 will explode. The blast will throw shards of stellar material in every direction, creating a beautiful supernova remnant that our descendants or perhaps otherworldly civilizations can admire for centuries to follow."

*Nebulae are a celestial favorite of mine. [The Lagoon nebula is one of the prettiest, IMO.]

CONTOUR failure; comet-bound craft broke apart??

*I don't recall the launch of CONTOUR...but that was 14 months ago. Hmmmm, hopefully they can figure out what went wrong.

Any comet enthusiasts here? Another member here and I remember the last time Halley swung around, in the 1970s...it wasn't as spectacular as had been anticipated, compared to its previous swing past the Earth.

I recall one of Arthur C. Clarke sequels to "2001: A Space Odyssey" ("2030," if I recall correctly) wherein he writes of a small manned expedition which lands on the nucleus of a comet. I think that's a rather fantastical idea.

Tr?s interessant... tr?s beau...

Alors, ch?re Cindy, j'?tudie le fran?ais; donc nous pousons comminquer en le langage, quand nous d?sirons, oui?

S'il vous pla?t, me corrige quand je ne parle pas correctement.

Spider-Man · 2003-10-30 10:18:16

Not to be secret, friend, but just to practice writing in a foreign language. Up 'til now, I've done Italian and she French. Now, as I did say, yes, we can practice French.

Then I said, so, dear Cindy, I am studying French; now we can comminicate in the language, when we desire, eh?

And then, If you would, please correct me when I don't speak correctly.

Forums are about learning from one another, aye? Might as well learn anything we desire if it's possible.

National Geographic article about Mars

*"High Lakes May Yield Clues to Life on Mars"

High altitude lakes on the Licancabur Volcano on the border of Chile and Bolivia may provide clues about the evolution of life in extreme environments on Earth and the existence of life on Mars. Laguna Verde, at an elevation of 15,330 feet (4,600 meters), is shown from the slopes of the Licancabur.

Solar Flares -- Double Wammy

*Very interesting. Discusses possible weakening of magnetosphere from the first onslaught.

"The back-to-back pairing of two historically huge flares is unprecedented, one physicist says." ... "Like the first, the second storm moved from the Sun to Earth in about 19 hours -- amazingly swift compared to the typical interval of two days. Kunches said the second one may have moved quickly in part because interplanetary space was cleared out by the first salvo, creating less drag. The science behind that possible scenario is not well understood, he said."

Any of you Canadians seeing spectacular northern lights?

A pair of strong solar storms that hit Earth late last week were squalls compared to the torrent of electrons that rained down in the "perfect space storm" of 1859. And sooner or later, experts warn, the Sun will again conspire again send earthlings a truly destructive bout of space weather ... In early September in 1859, telegraph wires suddenly shorted out in the United States and Europe, --->igniting widespread fires; colorful aurora, normally visible only in polar regions, were seen as far south as Rome and Hawaii.<---!!

When a large star goes supernova it effectively destroys all the surrounding star systems, either by shockwave, radiation or debris. It can leave behind a cooling nebula up to a thousand light-years in diameter. The nebula and shockwave can initiate stellar fusion in gas giants and flood Oxygen rich terrestrial planets with water (Hydrogen from the nebula plus Oxygen in the atmosphere).
I couldn't find any data, if Betelgeuse goes boom, will it throw into space enough hydrogen to flood our solar system ?
Supernova

*Interesting article, BGD.

Looks like we're "in for it" one way or another, eventually:

If Betelgeuse blowing doesn't adversely affect our solar system (I'd like to hear the input of others on just how that event might impact our solar system), or own star is going to blow in a few million years.

Getting out of our own solar system won't prove enough when our galaxy collides with the Andromeda galaxy.

And now scientists are seeing what they theorize is evidence our universe might be dying, and "the wave" is spreading...

Can we escape some day to another universe?

It's all very intriguing. I'm all for space exploration of course (provided it's done intelligently and in a non-destructive manner), but it's also important to live in the here and now, enjoying the (seemingly very rare) life we've somehow found ourselves in possession of.
