I enjoy watching sky @ night. And from d past 2 days, i've been observing strange shooting star like fragments after a definite period of time. say after 5 mins. yesterday i observed 4 such fragments in 15 mins. n today i saw 7 in 30 mins.
I've seen shooting stars lot many times and i m sure that these r not shooting stars but something else. Wat these cud be? Has anyone else also observed such phenomenon?

The Perseids are the biggest annual meteor shower, and have been observed and been famous for 2,000 years now, with the first known information on these meteors coming from the far east.
The shower is visible from mid-July each year, but the bulk of its activity falls between August 8th and 14th with a peak on August 12th. During the peak, rates of a hundred or more meteors per hour can be registered.
Each time a periodic comet swings by the Sun, it produces large amounts of small particles which will eventually spread out along the entire orbit of the comet to form a meteoroid "stream".
If the Earth's orbit and the comet's orbit intersect at some point, then the Earth will pass through this stream for a few days at roughly the same time each year, producing a meteor shower. The parent bodies (comets) of most known meteor showers have now been identified.
The Perseid cloud stretches along the orbit of Comet Swift-Tuttle. The cloud is comprised of particles ejected by the comet as it passed by the Sun. Most of the dust in the cloud today is approximately a thousand years old.
However, there is also a relatively young filament of dust in the stream that boiled off the comet in 1862. The approximate rate of meteors originating from this filament is much higher than normal.
Most meteors seen in meteor showers are caused by particles smaller than a grain of sand

It's the Perseid shower - we're passing through the tail of a comet, so there is more than the usual space dust about. The shooting stars should be coming from the direction of Perseus.

These are the Perseid meteor showers, an annual event at this time in August. You're lucky to see them; if it's overcast, or if you live in an urban area with light pollution, they aren't as visible. They last about two weeks.

They are just meteoroids.They burst in the space and some of the particles come very close to the earth.

You're seeing the Perseid shower, it peaks every year around mid-August.

sure, I now and back observe that once a questions gets starred it greater beneficial the prospect of people starring it. in some situations i'm inspired to action picture star questions via fact they already have stars. now and back I action picture star a query and people follow me. conversing of starring, this is one for you. i spotted six people have already starred the question, so i think of i visit stay with them!

metor shower. nothing to be worried about.
the metors are small and burn up in the atmosphere.
it's only a small shower however. larger ones can have hundreds of small metors that literally light up the sky.
