X-ray & IR Images of J144547-5931
Data from Chandra and Spitzer of a region near the Galactic plane have been combined to track down some of the Milky Way's heaviest stars, which can be very elusive. The images show Spitzer data and a bright Chandra X-ray source (blue) that coincides with a strong infrared signal. These are giant stars thought to be at least 25 times more massive than the Sun. They are very bright in X-rays because high-speed winds from their surfaces collide with material, creating shock waves that generate temperatures up to 100 million degrees.

Full-field IR Image
This image shows infrared data from NASA's Spitzer Space Telescope near the plane of the Milky Way galaxy. Dust and gas throughout the Milky Way obscures much of the view from optical telescopes near the plane of the galaxy. Infrared images suffer less obscuration but are extremely crowded with stars.
