Experts from the Australian Space Agency have revealed all about the mystery objects that washed up on an Aussie beach late last week.

On Friday, authorities closed down a section of Forrest Beach in Queensland after a series of objects were found on the shore.

It had been suspected the objects may have been debris from a satellite crash and could potentially be toxic.

However, ASA experts have now shed new light on the discovery, seemingly solving the mystery.

On Monday, a spokesman for the organisation said the recovered items had been recovered and were considered safe.

“The recovered objects appear to be pressure vessels from a space launch vehicle,” the spokesman said.

“The agency has identified the likely source — objects’ location and characteristics are consistent with debris from a foreign rocket body that recently re-entered the atmosphere from orbit.

“The agency is continuing to engage with international authorities to formally confirm the launch vehicle and launching state.”

While the technical term for the discovered objects is “pressure vessels”, they are more colloquially known by a name that resonates particularly well with fans of cult hit 1980s movies.

Flinders University associate professor Alice Gorman told the ABC the vessels were better known as “space balls”.

“This is a classic example of what is known as ‘space balls’,” she said.

“Things like these pressure vessels can be buoyant if there is no fuel in them, so they are likely to wash ashore.”

The ASA added that it was continuing to advise Queensland authorities on the incident — and that further debris could be found.

“Never touch, move, or recover suspected space debris and assume it to be hazardous,” the spokesman added.

“Move away and contact emergency services.”
