Stargazers across the UK will be able to enjoy the peak of one of the year’s “most prolific” meteor showers this week.
The Geminid meteor shower could offer spectacular sightings on Wednesday night – but experts said it is expected to peak during Thursday evening.
Up to 150 meteors with multi-coloured streaks of light could be visible per hour from much of the UK.
The shower will peak at about 7.30pm and, with the moon entering a new phase, the dark skies will help stargazers catch the sight.
Dr Minjae Kim, research fellow in the physics department at the University Of Warwick, said the Geminids have evolved “into one of the major astronomical events”.
“An interesting feature of the Geminids is that their radiant point, where the meteors seem to originate from, rises in the mid-evening,” he said.
“This means you can start watching this shower earlier in the night than most other meteor showers.
“These meteors are known for their brightness, speed and typically yellow hue.
“The Geminids are observable worldwide due to their nearly 24-hour peak duration, making them accessible during both night and predawn hours.”

How should people observe the skies?
Experts said people should be prepared for the cold weather.
They added viewers should lie flat on their backs with their feet facing south, allowing for the best view of the sky.
Dr Kim said: “The spectacle continues until dawn, offering ample opportunities for observation – aided by the long nights of December.
“In the UK, I would recommend you head out around 6-7pm, giving your eyes enough time to adjust to the night sky, enhancing the visibility of the meteors.
“The best viewing spot would be somewhere far away from urban lights – so rural areas will get the best viewing experience.”
What is the Geminid meteor shower?
The Geminids originate from a rocky asteroid called 3200 Phaethon with a comet-like orbit and were first observed in 1862.
The meteors, small pieces of interplanetary debris, appear to radiate from near the bright star Castor in the constellation Gemini.

According to the Royal Observatory in Greenwich, the Geminids are unusual as they can be multi-coloured – mainly white, some yellow and a few green, red and blue.
This is partly caused by the presence of traces of metals like sodium and calcium – the same materials used to make fireworks colourful.
The streaks seen in the night sky can actually be caused by particles as small as a grain of sand, and the Geminids are thought to be intensifying every year.
