'Giant, shape-shifting stars' spotted near Milky Way's black hole

Objects raise hopes of scientists managing to track 'blobs' being swallowed by black hole

A number of bizarre shape-shifting objects have been discovered close to the supermassive black hole at the centre of the Milky Way.

The blobs are thought to be giant stars that spend part of their orbits so close to the black hole that they get stretched out like bubble gum before returning to a compact, roughly spherical form.
