The discovery was made during the team’s observations of stars near the galactic center, where they identified 21 red stars that had not been seen before. These stars were found to be moving in unexpected ways, which led the team to investigate further.
Detecting a Massive, Previously Unknown Structure
The discovery was made using the Green Bank Telescope in West Virginia, which was able to detect a massive, previously unknown structure in the Milky Way Galaxy. The structure, which is made up of molecular gas, extends far into the distant parts of the Galaxy and has implications for star formation theories, as well as the structure, make-up, and total mass of the interstellar medium.
