A new study published February 15 in the Monthly Notices of the Royal Astronomical Society finds that the Andromeda galaxy is actually around the same size as our own galaxy. Scientists previously thought Andromeda was about two to three times the size of the Milky Way, and that it would one day swallow us up in a galactic smashup billions of years away. But researchers using a technique to measure “the speed required to escape a galaxy” have figured out why Andromeda is smaller than research has suggested, according to the International Centre for Radio Astronomy Research (ICRAR). This could seriously change the outcome of that eventual merger.
