Image Description
An artist’s concept of our Milky Way galaxy, highlighting its main components: the disk, bulge, stellar halo, and dark matter halo. Credit: NASA’s Goddard Space Flight Center Alt text: Infographic labeled Milky Way Anatomy. At the left, a face-on galaxy labeled “disk, 100,000 ly across,” has three components labeled: bar, 16,000 ly long, pointing to the bright, oblong core; spiral arms, pointing to the streams of stars that wrap around the core of the galaxy counter-clockwise; and interstellar medium, thin gas, dust, and particles between stars, pointing to a place in between the spiral arms. At the top right, an edge-on view of the galaxy looks like a CD with a ping pong ball in the middle. It’s labeled thin disk, 1,000 ly thick, pointing to the middle of the disk, and thick disk, up to 6,000 ly thick, pointing to an area slightly above the main part of the disk. The brightly glowing center is labeled bulge, contains supermassive black hole and 10 billion stars. Underneath, there are two zoomed out views of the face-on galaxy – one labeled stellar halo, 300,000 ly across has the galaxy surrounded by a faint glow. The other, labeled dark matter halo, 1 million ly across, is more zoomed out and surrounded in a mottled purple glow. Credit: NASA

Multiwavelength Milky Way

This collage shows the Milky Way in 10 different wavelengths of light, from radio waves to gamma rays. By studying our galaxy in different types of light, astronomers can learn far more than they could otherwise.

A poster titled Multiwavelength Milky Way. Ten thin rectangular strips are stacked on top of each other, each showing a different view of the Milky Way. Some appear like starry bands with brightly glowing centers, while others are false color visualizations. Credit: NASA
