Galactic Center: Caption and Credits

The data was obtained with observations of spectral line emission from ionized hydrogen (H) from the inner 10 light-years of the galaxy using the Very Large Array. This gas, which has been heated to 10,000 degrees Kelvin by cluster of hot stars in the center of the galaxy, exhibits complex motion. The 3-D rendering of the datacube allows the researchers to dissect different kinematic components and help determine whether gas is rotating around the center, or actually falling inward.
