A video, originally uploaded to Reddit, shows a doughnut shaped orb appearing above Canberra during a storm on Sunday night, faintly backlit with a red and green glow.

A spherical ball of light lit up the skies of the Australian Capital Territory before quickly disappearing into thin air. Social media users have suggested extraterrestrial activity while experts speculate ‘ball lightning’

Some Reddit users made suggestion that the light had opened up hyperspace.

Despite these claims Australian National University astronomer Brad Tucker told the ABC that he doesn’t think that it was aliens.

Mr Tucker said: ‘If it was, they might visit somewhere more active than Canberra.’

Sceptics have coined the video as a hoax with one Reddit user commenting ‘you managed to fool a lot of r*****s.’

But Mr Tucker, who is convinced that the incident was in fact ball lightning, said: ‘It’s probably not PH๏τoshop either. Everything kind of fits and it seems right.’

The energy used to create the unusual activity can usually occur when a lot of electrical charge is rubbed against the gases in our atmosphere.

Lightning and a greenish red hue appears in the sky. Suddenly a bright white orb appears and bursts into nothingness. The outline of the orb can still be seen for a few seconds before disappearing

‘Sometimes, if you get a really interesting occurrence, you create something called ball lightning’ said Mr Tucker.

The red and green glow was also suggested to be an aurora but Mr Tucker said although it holds the characteristics of an aurora ‘there was no activity from the sun’ which is needed, when trying to see an aurora in the sky.

‘It’s pretty amazing no doubt,’ he added.

Ball lightning is one of the strangest phenomena on our planet and is seen ‘more often in Australia than anywhere else.’

Australian National University astronomer Brad Tucker didn’t think it was aliens but suggested it may be the equally mysterious ball lightning weather phenomenon, which is often seen across Australia

A ball of light about the size of a grapefruit, with the intensity of a 40W light bulb illuminates for about ten seconds and then disappears.

The strange weather spectacle has been seen by hundreds of people but remains a mystery to this day, reported The Conversation.

Daily Mail Australia has contacted UFO expert Bill Chalker for comment on the event.

Meanwhile this comes after a bright orange streak of light was seen flying over the Northern Territory in October.

The UFO slowly shoots through the sky and experts speculated it could have been space junk re-entering the Earth’s atmosphere or a high alтιтude military jet with its afterburner.
