Out-of-control Chinese space station, Tiangong-1, is predicted to reenter Earth’s atmosphere at 11:30am BST (6:33am ET) on Easter Sunday.
The space craft is carrying highly toxic chemicals and could crash into a number of highly populated areas, researchers claim.
Areas that could be hit include New York, Barcelona, Beijing, Chicago, Istanbul, Rome and Toronto.
When the station does eventually enter the atmosphere it could unleash a ‘series of fireballs’ that will be seen by observers.
Scientists still do not yet know where the satellite fragments are likely to land.
