Make a wish! Don’t miss the Geminid meteor shower tonight 24

Calling all star-gazers! Remember to keep a lookout tonight for the “shooting stars” of the Geminid meteor shower, which occurred last night and will repeat again tonight in its annual appearance.

An estimated 150 meteors per hour will light up the moonless skies tonight and, if it’s dark and clear, you could catch a shooting star every couple of minutes from 10pm tonight until dawn.

“The Geminids are usually one of the two best meteor showers of the year,” says Alan MacRobert, senior editor at Sky & Telescope magazine.

Lower counts of Geminid meteors should be visible for a few nights before and after December 13th and 14th. If you live under the artificial skyglow of light pollution, you’ll see fewer meteors, but the brightest ones will shine through. Scattered light from a thin waxing crescent Moon will not interfere.

To watch for meteors, you need no equipment other than your eyes. But you’ll see more of them if you allow at least 20 minutes for your eyes to adapt to the darkness, according to Sky & Telescope. The experts say you should find a dark spot with an open view of the sky and no glaring lights nearby.

Bundle up as warmly as you can in many layers. “Go out late in the evening, lie back in a reclining lawn chair, and gaze up into the stars,” advises Mr MacRobert. “Be patient.”

These are the times from which the meteors can be seen around the country:

Brisbane 9pm (AEST)
Darwin 9:30pm (ACST)
Perth 10pm (AWST)
Sydney 10:30pm (AEDT)
Canberra 10:40pm (AEDT)
Adelaide 11pm (ACDT)
Melbourne 11pm (AEDT)
Hobart 11:20pm (AEDT)

Geminids can appear anywhere in the sky, so the best direction to watch is wherever your sky is darkest, probably straight up. Small particles create tiny, quick streaks. The occasional bright one might leave a brief train of glowing smoke. The few that you may see early in the evening will be longer, dramatic steaks continuing for a few seconds as they graze sideways through Earth’s uppermost atmosphere.

If you trace each meteor’s direction of flight backward far enough across the sky, you’ll find that this imaginary line crosses a spot in the constellation Gemini near the stars Castor and Pollux. Gemini is low in the eastern sky during late evening and climbs to high overhead in the hours after midnight (for skywatchers at north temperate latitudes). This special spot is called the shower’s radiant. It’s the perspective point from which all the Geminids, which travel in parallel through space, would appear to come if you could see them approaching from far away.

The Source of the Geminid Meteors

The Geminid meteors are created by tiny bits of rocky debris (mostly the size of sand grains to peas) shed from a small asteroid named 3200 Phaethon, which was discovered in 1983.

Phaethon is small, only about three miles across, and it loops around the Sun every 1.4 years in an orbit that approaches the Sun closer than any other known asteroid. Some researchers call Phaethon a “rock comet” that sheds dusty debris each time it nears the Sun, when its surface becomes heated to roughly 1,300°F (700°C).

Over the centuries, these bits of Phaethon have spread all along the asteroid’s orbit to form a sparse, moving “river of rubble” that Earth passes through in mid-December each year. The particles are traveling 22 miles per second (79,000 mph) with respect to Earth at the place in space where we encounter them. So when one of them dives into Earth’s upper atmosphere, about 50 to 80 miles up, air friction vaporises it in a quick, white-hot streak.

Will you be watching? What will you wish for?

    • Sorry that wouldn’t have made much sense – I heard it would be better tomorrow, but now I’ve been looking several sources say tonight will be best.
