Venus Disappears During Meteor Shower
April 17, 2009: Picture this: It's 4:30 in the morning. You're up and out before the sun. Steam rises from your coffee cup, floating up to the sky where a silent meteor streaks through a crowd of stars. A few minutes later it happens again, and again. A meteor shower is underway.
All of this is about to happen--for real.

On Wednesday morning, April 22nd, Earth will pass through a stream of comet dust, giving rise to the annual Lyrid meteor shower. At the same time, the crescent Moon and Venus will converge for a close encounter in the eastern sky. Viewed from some parts of the world, the Moon will pass directly in front of Venus, causing Venus to vanish.
The Moon-Venus conjunction is pure coincidence. It has nothing to do with the Lyrid display other than insurance. Even if the shower fizzles, the sight of a 9% crescent Moon located so close to brilliant Venus is guaranteed to make your day.
Most observers will see only a close gathering of the two bodies. People in western parts of North America are favored with more--a full-blown eclipse or "occultation." Around 5 a.m. Pacific Daylight Time, Venus will disappear behind the mountainous rim of the Moon and reappear 60 to 90 minutes later. Click on the map for local details:

Do not worry if the sun rises during the occultation, because Venus and the Moon are bright enough to see in broad daylight. Locate the pair before sunrise, so you know where they are, then follow them up the brightening sky using binoculars or naked eyes. Some people say Venus and the Moon are most beautiful when surrounded by morning blue.
On Wednesday morning, April 22nd, you can see for yourself.
