Why is it That I never hear about these things (rocket launches, eclipses, meteor showers, etc.) before they happen?

Get off of the game on occasion, then read other stuff besides BBS

No, actually you can read Space.com, NASA website (or TV Channel), SLOOH.com or other site.
Plenty of info on launches and other Space related things to watch for

Lots of stuff going on right now (Comet, Meteor Showers, etc.)
On the 28th, the Comet ISON will put on quite a show, as it races towards the Sun
