New research suggests our galaxy is much bigger than once thought and that it is moving much faster than earlier predicted.
The result is that collisions with other galaxies will happen much sooner than scientists had previously thought – still billions of years away.
News wrap:
USA Today: Our galaxy now 50 per cent bigger, sharper – with four arms
Newsweek: That collision you hear will be Andromeda
Times: Hold on, galaxies may be on a collision course
Scientific American: Milky Way now in larger size
Sky & Telescope: Milky Way doubles its mass
