Our Milky Way galaxy is home to some extremely weird things, but a new discovery has astronomers truly baffled.
In data collected by a powerful radio telescope, astronomers have found what appears to be a perfectly spherical bubble. We know more or less what it is – it’s the ball of expanding material ejected by an exploding star, a supernova remnant – but how it came to be is more of a puzzle.
A large international team led by astrophysicist Miroslav Filipović of Western Sydney University in Australia has named the object Teleios, after the ancient Greek for “perfection”. After an exhaustive review of the possibilities, the researchers conclude that we’re going to need more information to understand how this object formed.
