Wandering through the realms of the cosmos, pondering its huge vastness

Planets Align for This Year’s Lyrids!

Tonight presents the expected peak of the annual Lyrid meteor shower, from late night Friday (April 22) until dawn Saturday (April 23). Look for meteors radiating from the constellation of Lyra after midnight.

Lyrid meteors are usually around magnitude +2, which is bright enough to be visible from most cities, but you’ll see more and enjoy them more if you leave the city for a dark place where the stars shine brighter. They often produce luminous trains of dust that can be observed for several seconds. Some Lyrids will be brighter, though, and the occassional “fireball” can cast shadows for a split second and leave behind glowing, smoky debris trails that last for minutes. Lyrid meteors disintegrate after hitting our atmosphere at a moderate speed of 29.8 miles per second.

In observing these meteors, the hour before dawn is usually best, except that a bright waning gibbous moon will be lighting the sky hiding most of the fainter meteors in its glare. This year, it is more favorable to watch late at night, during the dark hour before moonrise.

Tweet your data!

You can also share your data by Tweeting your postcode, your country (click here to find your country code) and, optionally, the meteor count along with the hashtag; #MeteorWatch (you are welcome to use GAM hastags as well – #GAM2011 #LyridsWatch)

The meteor data will appear in a map at MeteorWatch.org


While the best meteor-watching will be late night through daybreak, it’s well worth staying outside just before sunrise for a beautiful planetary alignment will be joining the Lyrids.

Venus is so bright in the eastern sky you can’t miss it, and below it Mercury, Mars and Jupiter could be found hanging a few degrees away from each other. If you have hazy skies or live in an urban area, you may need binoculars to see Mars and Jupiter.

All four heavenly objects will fit within a circle about 15 degrees in diameter, beaming together through the colors of the predawn sky. 

This planetary grouping is visible from April 23 to May 30.

Enjoy the show! :)
