the Center of our Galaxy

Two astronomers have discovered that an enormous X-shaped structure made of stars, lies at the central bulge of our Milky Way Galaxy.

Astronomers Dustin Lang and Melissa Ness found, with the help of Twitter, an “enormous X-shaped structure made of stars,” that could point the center of the Milky Way.

They analyzed data from the Wide-field Infrared Survey Explorer (WISE), and then Lang tweeted a link to his interactive galaxy map, and Ness spotted the X.

The two scientists published their findings in Astronomical Journal.

Lang told

“That’s the power of large surveys and open science!”
