Offiicials have established an exclusion zone and placed the balls inside sealed containers
Six mysterious metal balls have washed up on a beach over the weekend, sparking speculation over what they could be.
Mystery metal balls washed up on an Australian beach and were discovered over three days from Friday to Sunday on Forrest Beach, around 10 miles southeast of Ingham in Queensland.
Australia’s Space Agency said the objects “appear to be pressure vessels from a space launch vehicle” and are now being examined to determine exactly where they came from. Officials believe their location and characteristics are consistent with debris from a foreign rocket body that recently re-entered Earth’s atmosphere.
The agency said it is working with international authorities to formally identify the launch vehicle. A 50-metre (160ft) exclusion zone remains in place around the objects while investigations continue.
Queensland Fire Department officials have urged members of the public not to touch any suspicious debris and to move away immediately before contacting emergency services. There had been widespread speculation online that the spheres could be rocket propellant tanks, raising concerns they may still contain traces of highly flammable or hazardous chemicals.
Local media reported specialist crews wearing protective suits removed five of the six objects under police guard before placing them inside hazardous material drums. Experts say pressure vessels like these are often made from titanium alloy, allowing them to survive the intense heat generated as spacecraft re-enter the Earth’s atmosphere.
Dr Alice Gorman, an associate professor at Flinders University, said: “Many rockets and spacecraft have liquid fuel systems that involve fuels under high pressure that are in these pressure vessels made of robust material. These parts of the fuel system often survive because their melting points are higher than the temperature coming back through the atmosphere.”
Forrest Beach Takeaway owner Lisa Scobie said the discovery had brought unexpected excitement to the quiet coastal community. She said: “It’s very quiet, not a lot happens here. So having a lot of extra activity… that definitely created a little bit of excitement.”
It is not the first time suspected space debris has washed ashore in Australia. In 2023, Indian officials confirmed that a giant metal cylinder found on a beach in Western Australia had come from one of the country’s Polar Satellite Launch Vehicles after re-entering the atmosphere.
A similar metal sphere was also discovered in remote grassland in Namibia in 2011, with experts at the time believing it was most likely a fuel tank containing hydrazine from an unmanned rocket.
