This image shows one of the two ‘exact matches’ to the Milky Way system found in a new survey. The larger galaxy, denoted GAMA202627, which is similar to the Milky Way clearly has two large companions off to the bottom left of the image.

Here’s something astronomers haven’t seen before: galaxies that look just like our own Milky Way. It’s not that our spiral-armed galaxy is rare but instead the whole neighborhood in which we reside seems to be unusual. Until now, a galaxy paired with close companions like the Magellanic Clouds has not been found elsewhere. But using data from a new radio astronomy survey, astronomers found two Milky Way look-alikes and several others that were similar.
“We’ve never found another galaxy system like the Milky Way before, which is not surprising considering how hard they are to spot!” said Dr. Aaron Robotham with the International Centre for Radio Astronomy Research (ICRAR). “It’s only recently become possible to do the type of analysis that lets us find similar groups.”
