The Milky Way's spiral structure was discovered over 175 years ago in 1850. But new information could completely change our understanding of our cosmic home. Astronomers have taken a new look at our Milky Way galaxy using data from NASA's Chandra X-ray observatory and the European Space Agency's XMM-Newton observatory and have pieced together new, precise measurements of the galaxy's spiral arms. And what they found is that its spiral arms stretch out farther than we once thought, a discovery that could change our understanding of our galaxy's structure.
"The differences are small, but any revision of these distances is important because they are so fundamental for understanding our galaxy," co-author Ilaria Fornasiero said in a statement. "For example, this could mean that astronomers have to revise estimates of the mass of the galaxy, because that affects how wide the arms stretch."
To make this new galactic measurement, researchers had to get a little creative with the data. They measured these cosmic distances by observing X-ray light scattered by the dust in the Milky Way's arms as it echoed out from around gamma-ray bursts, or the most powerful explosions across the universe that happen either when massive stars collapse or neutron stars collide and merge. These massive bursts of energy are happening far beyond our galaxy, but their X-ray light is so powerful that it can reach and bounce off of dust clouds in the Milky Way's arms.
