PERSEIDS WILL BE STARRING IN NIGHT SKY.


Byline: PATRICK ST. MICHEL

Staff Writer

To cap off this weekend with a great, free show, simply go outside -- and look up.

The annual Perseids meteor shower meteor shower, increase in the number of meteors observed in a particular part of the sky. The trails of the meteors of a meteor shower all appear to be traceable back to a single point in the sky, known as the radiant point, or radiant.  will illuminate the sky -- in all directions -- beginning tonight. It will reach its peak about 9 p.m. Sunday, with one or two meteors appearing every minute.

Named after the constellation Perseus, the shower originates from the comet Swift-Tuttle. The comet's tail, a collection of debris that has fallen off the actual comet, intersects Earth's atmosphere “Air” redirects here. For other uses, see Air (disambiguation).

Earth's atmosphere is a layer of gases surrounding the planet Earth and retained by the Earth's gravity. It contains roughly (by molar content/volume) 78% nitrogen, 20.95% oxygen, 0.93% argon, 0.

Tiny bits of dust from the comet's tail hit the atmosphere traveling at extremely high speeds, causing streaks of light.

Ed Krupp Dr. Edwin C. Krupp is an American astronomer and the director of the Griffith Observatory in Los Angeles since 1974. He received his PhD in astronomy from UCLA in 1972. His PhD advisor was George Abell. , director of the Griffith Observatory, said the Perseid shower is one of the most reliable and regular meteor showers and this year's version will be better than usual.

"The meteors will be much easier to see this year," he said. "This is a good year for Perseid."

David Sovereign, president of the Los Angeles Astronomical Society, said the shower may be more visible than in previous years, but he recommended people still head out of the city to watch the cosmic show.

"Perseids will be more visible outside of the city," he said. "Los Angeles has too much light pollution to see the meteors."

Krupp also supported an escape from the city.

"The observatory encourages people to get out of town, and we can't provide a good view," he said. "We want people to truly experience the joy of seeing a meteor shower."
