It was completely unexpected for a rocky fireball to have travelled such vast distances from the most distant region of our Solar System, called the Oort Cloud. High-tech fireball cameras developed by Curtin researchers and run by the University of Alberta captured vision of this volleyball-sized rocky meteor, weighing about 2kg. Since then, we have been able to conclude that all signs point to this dazzling fireball originating from a region much further away than we ever would have anticipated – the Oort Cloud. The Oort Cloud is a collection of icy objects sailing through space that – until now – had not offered any direct objects for scientists to observe. This new discovery showed a significant amount of rocky material was co-existing with the icy objects already known to call the Oort Cloud home. The presence of this rocky meteor from that location can not be explained by our current understanding of the formation of the Solar System.
