Astronomers are expecting to see about a dozen meteors as Earth passes through an area of space “littered” with the debris of Halley’s Comet.

The Orionid meteors appear every year at this time, with showers producing 20 or so meteors every hour.

The news comes as the Evening Times reports how the usually shy milky-green gas giant is set to show in skies across the world today (Thursday).

Here’s everything you need to know about the celestial Orionid event and whether you’ll be able to catch it over Glasgow:

Why is it called the Orionids?

It is because the meteor shower appears to emerge from the constellation Orion – which is one of the brightest groups of stars in the sky.

It is expected to rise this weekend after 2130 BST.

Meteoroids from Halley’s Comet strike Earth’s atmosphere at a speed of 148,000mph, burning up in streaking flashes of light.

“The annual Orionids meteor shower peaks this weekend, as the Earth passes through debris left behind by the famous Halley’s Comet,” said astronomer Tom Kerss, of the Royal Observatory Greenwich.

“The Orionids is a modest shower, producing around 20 meteors per hour at best under absolutely perfect conditions.”

When is the best time to see it?

The shower is active throughout October, but Kerss reckons the best time to see it will be on October 22 between midnight and dawn, when the sky is darkest and the shower will be at its brightest.

“We expect the peak to occur on the night of 21/22 October (Saturday night and Sunday morning) when the young crescent Moon will set conveniently before the radiant of the shower – the point from which the meteors appear to spread out – rises in the East,” said Kerss.

“Make a plan to stay out between midnight and 3am on Sunday morning to give yourself the best chance, and enjoy the thrill of seeing tiny flecks of Halley’s Comet disintegrate at hypersonic speeds (safely) above your head.”

How will you be able to watch it?

Get as far away from all artificial lights as you can and allow at least 45 minutes for your eyes to adjust to the dark.

“There’s no advantage to using binoculars or a telescope, your eyes are the best tool available for spotting meteors, so relax and gaze up at the sky, and eventually your patience will be rewarded,” said Kerss.

“Meteors can appear anywhere in the sky, though if you have to pick a direction, you might fare slightly better looking east.”

To maximise the chances of seeing the shower in all its glory, have your back to the Moon or make sure it’s hidden behind trees or buildings so the sky isn’t too bright. And don’t forget to take that blanket.

What is the weather outlook for Glasgow?

Glasgow Times:

As expected, Glasgow’s weather forecast for the weekend could be better.

According to the Met Office, the outlook, so far, stands at: “Very unsettled on Saturday with rain and strong to gale force winds. Winds slowly ease on Sunday with a mix of sunshine and showers. Further rain is expected on Monday.”

However, we’re hopeful the weather will clear up late at night, possibly giving keen stargazers a glimpse at the heavenly event.
