Venus and Jupiter appear close in the sky as summer's best meteor shower peaks soon

(AP Photo/Wilfredo Lee) WASHINGTON — Summer's most dazzling meteor shower, the Perseids, peaks early Wednesday. At the same time, Venus and Jupiter will converge in the sky — overlapping like a very bright star. If your focus is the meteor shower, it's worth knowing that this year a bright moon will dampen viewing during the pre-dawn peak, so some experts recommend waiting a week or so to glimpse shooting stars against a darker sky. The Perseids 'are an incredible meteor shower,' said Thaddeus LaCoursiere, planetarium program co-ordinator at the Bell Museum in St. Paul, Minnesota. Under dark skies with no moon, the Perseids can produce between 60 to 100 meteors per hour, he said. Since the moon will be around 84 per cent full during the peak, skywatchers might expect between 10 to 20 meteors per hour, according to the American Meteor Society. 'This year I'm actually recommending that people go out a little bit later' — a week or so past the peak when the moon will not be as bright, LaCoursiere said. Viewing of the Perseids lasts until August 23. What is a meteor shower? As the Earth orbits the sun, several times a year it passes through debris left by passing comets and sometimes asteroids. The source of the Perseids is debris from comet 109P/Swift-Tuttle. When these fast-moving space rocks enter Earth's atmosphere, the debris encounters new resistance from the air and becomes very hot, eventually burning up. Sometimes the surrounding air glows briefly, leaving behind a fiery tail — the end of a 'shooting star.' You don't need special equipment to see the various meteor showers that flash across annually, just a spot away from city lights. How to view a meteor shower The best time to watch a meteor shower is in the early predawn hours when the moon is low in the sky. Competing sources of light — such as a bright moon or artificial glow — are the main obstacles to a clear view of meteors. Cloudless nights when the moon wanes smallest are optimal viewing opportunities. And keep looking up, not down. Your eyes will be better adapted to spot shooting stars if you aren't checking your phone. When is the next meteor shower? The next major meteor shower, the Orionids, peaks in late October. ___ The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute's Science and Educational Media Group.

How to watch two meteor showers peak together in late July
WASHINGTON (AP) — It's almost time for summer's meteor shower duet. The Southern Delta Aquariid and the Alpha Capricornid meteor showers peak at the same time — in the early morning of July 30. Without too much interference from moonlight — the waxing moon will be only about a quarter full — the meteors should appear bright and clear in regions away from city lights. With each shower expected to produce up to a dozen visible meteors per hour under dark skies, the doubleheader means the total number of meteors 'do add up,' said Thaddeus LaCoursiere, planetarium program coordinator at the Bell Museum in St. Paul, Minnesota. 'Look for flashes of light in the night sky,' he said, adding that both are 'very nice classic meteor showers.' The Alpha Capricornids — produced by slower-moving meteors — may have tails that linger slightly longer in the sky, said Nick Moskovitz of the Lowell Observatory in Flagstaff, Arizona. Viewing of each shower lasts through August 12. What is a meteor shower? As the Earth orbits the sun, several times a year it passes through debris left by passing comets and sometimes asteroids. The source of the Delta Aquariids is debris from comet 96P/Machholz. The Alpha Capricornids stem from the comet 169P/NEAT. When these fast-moving space rocks enter Earth's atmosphere, the debris encounters new resistance from the air and becomes very hot, eventually burning up.
