    I would like this thread to be a thread for the amateur astronomers and those that are simply interested in astronomy to come to post or read the latest astronomy stories that interest the members.

    To start it off here's mine for the day.


    Meteorites Rain on Northern Illinois

    A chunk of interplanetary debris detonated into the sky over northeastern
    Illinois just before midnight on March 26th, dropping a rain of meteorites
    onto Chicago's suburbs. In Park Forest, a five-pound stone punched through
    the roof of a home and rolled to a stop not far from the bed of a sleeping
    13-year-old. Rattled residents flooded police and fire stations with
    calls, as the bolide's atmospheric entry rivaled the Sun and could be seen
    from as far away as Ohio. The intruding meteoroid had an estimated
    diameter of 1 or 2 meters and a mass of perhaps 10 tons. No one was
    injured by the falling fragments, and scientists have asked that residents
    turn in any pieces they find.

    Hey Mac Bandit

    I was home on spring break and I live in the town next to the meteor strike point.

    It was realyl freaky actually I was working on my website and I thought it was the start of a t-storm but no. I was also hopign to be the first one to post that story oh well. I heard it went thru a few floors of the house like 2nd level frist level and landed in the basement. Kinda reminded me of that simpsons episode .... the size of a chiuaha's head.

    About 10 years ago there were two fireballs that hit within the small valley I grew up in within about 3 years of eachother. The valley is about 15miles by 15 miles. It's kinda freaky to hear a concussion and to look up and see this fire ball of rock streaking through the sky with the mountains surrounding the valley in the background letting you know that it's low and within the valley. The first time this happened nearly about 13 years ago the sonic boom shook people out of there beds. It was the talk of the town (800 people) for months.

    This is a long time main stay of mine. They have a nice daily audio program.

    Yes, very cool. I like it when new evidence disprooves old theories. It prooves the one thing we all know. That we know nothing.

    Planetary disc around another star photographed.

    http://skyandtelescope.com/news/current/article_911_1.asp

    This is really cool. I didn't think photos of this magnitude would happen for at least another 20 years. Hubble just continues to amaze me. I wonder what sort of magnification they needed?

    According to my physics teacher the astroid that hit chicago was sold for 12k. i think the person coudl ahve gotten alot more if they would have held out a little longer...

    true, but I'm thinking it would take more than that for me to sell it. I'd want to keep it.

    As for the proto star system, very cool stuff. What will be even better is the NGST (next gen space telescope). Its going to be able to make the Hubble images look like an old 640x480 digital camera ;)

    From what I understand it should be able to. Maybe just maybe we will finally see what a quasar looks like.

    I would hold out for a larger sum, from what I know actualy meteorites are quite rare because even tho they land every once and a while they are rarely found...

    Well, I went looking for some more info on it and found out that its been named the James Webb Space Telescope.

    http://www.stsci.edu/jwst/

    Intersting bits - 2010 for deployment, quite a ways a way.

    But its not going to orbit the earth!! They're going to put it around a Lagrange point 1.5 million kms from earth. That's going to be very cool, but if it has any problems, there aren't going to be any shuttle missions to fix it.

    Unless that nuclear ion drive system gets working by then ;)

    Wow what a cool idea. A geo-solar stationary orbit. It will always be in the Earths shadaw that will be very advantageous.

    Yeah, its very cool. And there are a couple more besides that one. But this will be the first time we'll have sent something out that far to 'orbit'. Imagine what the pics of the moon and earth will be like? That's thats going to be very cool.

    Jupiters got some more moons.....

    http://www.cnn.com/2003/TECH/space/04/05/jupiter.moons.ap/index.html

    So when are they going to stop counting? Saying something only a mile across is a moon is pretty much granting it that status as a technicality.

    If that's the case, then when we actually get a good look at the objects orbiting Saturn in its rings, that planet will end up with 10,000s of moons.

    Re: Jupiters got some more moons.....

    I agree that they need to define a moon better. Also I was watching StarGate SG1 the other day and they happened to be arguing about the fact the (planet) they were on was actually a moon. Well I think that definition needs to be refined also. I think some of the larger moons of Jupiter could actually be defined as a planet.

    I don't know what the mean size of the objects are in the rings of Saturn but you could very well be right about the quantity of moons though I don't know for sure. I'm waiting for a closer analysis of the rings to find out exactly what ther makeup is. If they are mostly rock then it's quite possible that it use to be one big or two big moons that colided and created the rings. I know about the theories that the rings are mostly ice but I don't believe they have conclusive evidence.

    Huge Gamma ray burst.

    http://skyandtelescope.com/news/current/article_914_1.asp


    Have any of you ever wondered if these gamma ray bursts and some of these other bizarre flashes they pass off as natural astonomical activity could be some sort of huge intergalactic war. Wouldn't that be startling to discover. I mean how do we know what some sort of advanced weapon would look like from 2 Billion light years away.

    Ha, a DeathStar of sorts, making a sun go black hole.....nice way to take out a civilization.

    I certainly hope that's not the case. Even if such a thing, or a sun going nova in our general stellar neighborhood, we'd have problems with the radiation.
