Lyrids Meteor Shower, April 21st -April 22nd - Lyre, Lyre - Sky on Fire


The constellation Lyra, is the radiant, or point of origin, for the Lyrids Meteor Shower.  Lyra, whose principle star is Vega, rises out of the northeastern part of the sky after 10:00 p.m.  The Lyrids shower runs from April 16th through the 25th, but the peak time for viewing will be during the pre-dawn hours of April 22nd, after the moon has set (Waxing Gibbous in Virgo at 91.2 % full).  This meteor shower is one of the more conservative displays we see in the meteor season, raining between ten to twenty meteors per hour.  However, according to astronomers, the Lyrids will sometimes surprise you with surges of up to one hundred meteors per hour.

According to myth, Orpheus, the son of Apollo and Calliope, was a musician.  His best known gig was playing lead lyre for Jason and the Argonauts.  His father, Apollo, gave Orpheus a lyre that’s sound was so pure and enticing, its music charmed everything - even the rocks in the field.  It also charmed a beautiful nymph named Eurydice, who fell in love with Orpheus and married him.  

It’s not easy being the half-mortal child of a god. Just ask Percy Jackson. Orpheus and Eurydice’s happiness didn’t last. One day, while running from an ardent admirer (a common pastime for beautiful nymphs), Eurydice was bitten by a snake and died.  Orpheus in his grief followed her into the underworld and pleaded with Pluto for her return. Pluto agreed, with one condition.  Orpheus must lead his wife from the underworld, but never look back at her until they were above ground. You guessed it; for whatever reason, he looked back.  Later, after Orpheus’ death at the hands of crazed fans during a bacchanalia, Jupiter placed the magical lyre in the sky for all to see.

The cosmic debris responsible of the Lyrids display comes from the tail of Comet Thatcher.  This comet appears in our neighborhood every 415 years and we pass through its debris field every April.  Comet Thatcher was discovered on April 5, 1861, a week before the beginning of the American Civil War.  Its discovery clearly lent credence to the old superstition that the appearance of a comet preceded catastrophic events.

Meteor watching requires no protective eye gear.  All you need is a dark sky, a blanket and maybe a lawn chair.  It’s a natural spectacle, rated G, devoid of CGI and Dolby Sound.  More importantly, like starlight, meteor showers are free.

Perseid Meteor Showers Peak August 11th to the 13th - Beware of Triffids!

The Eagle Nebula which has nothing to do with Perseus,
but you must admit, makes a delightful picture!
How many wishes can you make in an hour?  Fifty? Eighty?  A hundred? You may get your chance to find out this coming weekend.  During the nights of Saturday the 11th, through Monday 13th, the Heavens rain fire over planet Earth in an annual event call the Perseid Meteor Shower.

Whenever we experience a meteor shower, and especially one that's purported to be the greatest cosmic event of our lifetime, I get nervous.  You see, I think about the old 1962 film based on the book by John Wyndham, "The Day of the Triffids."   In the story, everybody on the planet goes out to watch this once in a lifetime meteor shower, cunningly
engineered by alien plant spores called Triffids.  The meteor shower causes wide-spread blindness, making the Earth's population easy prey for slow moving, carnivorous plants.  And you think ivy is a problem.  Now, we both know that alien plant life is not planning to invade us by way of a meteor shower.  Still, every time I watch one, part of me listens for that weird, low-pitched clicking sound the Triffids made.  My husband, merry prankster that he is, does a pretty good imitation.

Back to reality.  Why is it called the Perseid Meteor Showers?
Tarot's #17, The Star from

 The radiant, or origin of the shower comes from the constellation named for, Perseus, the ancient Greek hero who battled Medusa.  You can locate Perseus in the northeastern sky and its most well-known star is called, Algol.  The name, Algol comes from Arabic (the ancient study of astronomy began in the Middle East) and roughly translates as, demon's eye.  The star actually represents Medusa's eye.  (Great. Now we have carnivorous plants and Gorgons. ) Algol is actually 105 lightyears away from us.  Think about the time and distance these meteors have traveled just to put on a show for us.

The Perseid display began around July 23rd this year and the meteors, refuse from comet, Swift-Tuttle, fell at a rate of 10 meteors per hour.  As we've moved deeper into the meteor stream, the fall rate has steadily increased.  Experts predict that during the shower's peak fifty to a hundred meteors will fall per hour.  The Perseid peak runs from August 11th through the 13th this year with meteors falling at a rate of thirty-seven miles per second.   


The meteor display will be easier to see this year because the moon is in a waxing crescent phase.  This will not be the case in 2014 however, so don't let this year's shower pass you by. The best time for viewing will be in the pre-dawn hours. 
You don't need eye protection, or smoked glass to watch the meteor shower.  Just try to get away from city lights if possible.  All that's required is a pillow for your head as you lie 
back in the grass.


Below is a table of the biggest annual meteor showers.  As you can see, we still have some great cosmic fireworks remaining for this year.  Enjoy!  Oh, and keep an eye on the plant life.  :)
