Well, it's not going to be quite as warm this weekend as it was yesterday (75 here in NYC), but there's another reason to enjoy the fresh spring air.
METEOR ALERT: Earth is now entering the dusty tail of Comet Thatcher (C/1861 G1), and this will cause the annual Lyrid meteor shower. Forecasters expect the shower to peak on April 22nd, producing about 10 meteors per hour--modest, but pretty. The best time to look is during the hours before dawn on Saturday morning. Go to a dark site away from city lights, if possible. [full story]
The Moon will also encounter the comet's tail on April 22nd, which raises an interesting possibility: Amateur astronomers may be able to see flashes of light on the Moon when comet debris hits the lunar surface and explodes. All that's required is a backyard telescope and lots of patience.
Tonight, load Stellarium onto your laptop so you know what you're looking at and head our to a field or street away from the city lights, and look up between the constellations Cygnus and Hercules, right near Vega. You should be treated to a plethora of "falling stars".
