The Meteor Shower Continues

The Perseid meteor shower continued last night even though everyone at the Bear Sanctuary was disappointed because of thick cloud. This picture was taken of a shooting star hurtling towards the earth at around 140,000 miles per hour.

The smaller, diagonal lines on the photo are normal stars, which are blurred because of the long time exposure needed to record the movement of the shooting star. The longer, almost vertical line is the shooting star, which is made from grains of dust falling off the comet Swift-Tuttle as it speeds through space.

When the Earth crosses the comet’s trail, the debris burns up in the atmosphere, producing the dazzling flash of light. As the particles, which are no larger than a grain of sand, hit the atmosphere, they burn up, producing trails of light that shoot across the sky. Although the shower has passed its peak, shooting stars will be visible for several more days. If you want to see the effect, then look to the northeast on a clear, cloudless night.

The meteor shower is still expected to be visible again tonight.

We Are Not Going To Die!

Last night the Bear Blog was inundated with people thinking the world was going to end. Some went one further and suggested that the Earth was going to be hit by a giant meteor at 10:30 last night. The fact that we are still all here today is proof that what people were saying was false but where did the story come from?

According to NASA, we are being showered with debris from the Perseid Meteor. The meteor passes the Earth once every 133 years and usually puts on a good display for sky-watchers. However, the meteors showering the Earth are so small they are no danger to us. Tonight the shower could produce a display of up to 80 tiny meteors per hour. “A waxing crescent moon will set before the shower becomes active, setting a perfect stage for meteor watching,” said the US Space Agency.

Experts are telling people to head away from city lights for the best views. John Mason from the British Astronomical Association said, “Weather-permitting, we should be in for a very good show across the UK. The shower has been ongoing for a week now and we have already seen some very bright meteors whizzing overhead.”

However, it must be stressed that The Perseid meteor shower is caused by debris from the comet Swift-Tuttle that is in no danger of hitting the Earth. Every 133 years, the huge comet swings through the inner part of our Solar System and leaves behind a trail of dust and gravel. When the Earth passes through the debris, specks hit our atmosphere at 140,000mph and disintegrate in flashes of light.
