Perseid meteor shower August shows are among the most popular year of heaven, and offers a great opportunity to drink a big gulp of the goodness of the night sky. What if this year's shower of meteorites will not be as spectacular as it could be? There are still plenty of ways to get more out of this year's Perseid performance. First, a reality check: In a normal year, observers could detect more than one meteor per minute under optimal viewing conditions during the peak of the Perseids, which usually comes in the night of August 12 to 13 . The conditions are not optimal this year, however, because the moon is large and complete what is traditionally the best times for observing meteors between midnight and dawn. All the glow becomes more difficult to see the rapid and feeble rays of light at night.
The best strategy is to find a vantage point that is free of clouds and city lights, and also has a blockage in the south, which has a possibility of blocking the moon's disk - be it a barn, a tree or a mountain. Anything that reduces the brightness will increase your chances of seeing the Earth passes through several meteoroid streams meteors.The as it orbits around the sun. When a comet approaches the Sun, turns and throws hot gas and dust. The gas then forms a tail of dust and leaves.
When Earth passes through this dust, the particles enter our atmosphere at the speed of light and heat, resulting in meteorites.
An encounter with a most densely populated patch of material results in a meteor shower, which occurs a few times per century.
There are three things that define a meteor shower: the time of its peak, the amplitude of this peak, and the expected number of meteors per hour.
The Perseid shower occurs in the second week of August and is nourished by the dark and pleasant temperatures. The average viewer is 90 meteors per hour falls.
The Moon is making a big splash of cold water in the shower this year, the Perseids, so it is difficult to see. But that's OK: if you can not see them, why not listen?
Sounds strange, but thanks to SpaceWeatherRadio, now you can! You're not really hear the sound, of course: the meteors burn up in our atmosphere at an altitude of 100 km or so too high for direct sound waves. However, the Air Force has a surveillance radar facility in Texas that the beams of radio waves in the sky. When a bit of fluff from cosmic rays through our sky, leaving the way ionized reflected radio waves, producing an echo. This translates radio waves into sound, so you can actually hear a meteor! Here is an example of a Geminid meteor shower, which sounds like it could have been lying right next to the soundtrack of "Forbidden Planet". There is also information on how this works on the website of NASA science.
If you listen live, here. I had to go for a while and heard several faint but clear die "Eeeeeeeoooooooo" meteor sounds within minutes (and other sounds clear I'm not sure I can identify what makes it all even cooler). The best time to listen to the Perseids is after midnight Texas (Central) time, but if you let it run you're bound to hear some creepy sounds from the speakers.
