milky way galaxy center spitzer infrared

A NASA photo captures the center of the Milky Way galaxy in infrared light.
The image shows the galactic center in unprecedented detail, but NASA’s upcoming James Webb Space Telescope (JWST) will produce even better photos.
JWST’s powerful infrared cameras might even capture the disk of hot matter swirling around the supermassive black hole at the galaxy’s center.
Future images of the galaxy’s center could help scientists answer questions about how the Milky Way formed and how it evolves over time.

The center of the Milky Way is a crowded hub of millions of stars, bathed in harsh ultraviolet and X-ray radiation, swirling around a black hole as massive as 4 million suns.

A shroud of dust and gas makes it difficult to see all that activity, but NASA’s Spitzer telescope cut through the fog with infrared sensors in 2006, producing an unprecedented image. The agency republished that photo (shown above) on Wednesday in order to highlight how much more we’ll be able to see with its next venture.

That project, the James Webb Space Telescope (JWST), is slated to launch in 2021. It will use more advanced infrared cameras to image the …read more
