Social media feeds across Australia were alight with footage of what people thought were UFOs flying over Queensland and northern New South Wales on 30 July.
But experts say what people actually saw was a Chinese rocket as it passed over Australia.
Professor Jonti Horner was able to match the sightings from his home state with a Long March 8A rocket launch from Hainan. The rockets are used to launch satellites for China’s state-owned internet network into space.
