WEEKEND METEORS: Earth is entering the dusty tail of Comet Thatcher, and this will cause a mild meteor shower this weekend. It's called the Lyrid meteor shower because the bits of incandescent comet dust appear to come from the constellation Lyra. The best time to look is during the dark hours before dawn on Sunday, April 22nd, and Monday, April 23rd, when you can expect to see a shooting star overhead every 5 minutes or so: sky map.
