New observations suggest the Milky Way's spiral arms may be larger than previously estimated

Summary
New observations using data from NASA's Chandra X-ray observatory and ESA's XMM-Newton observatory suggest that the Milky Way galaxy's spiral arms may be larger and more extensive than previously thought. Astronomers used cosmic explosions to take precise measurements that challenge the long-standing understanding of our galaxy's structure, which was first discovered over 175 years ago in 1850. The findings could fundamentally change our understanding of the Milky Way's size and shape.

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.
