A giant molecular cloud has just been discovered in the Milky Way. This structure, located 23,000 light-years away, weighs the equivalent of 160,000 times our Sun. Using the Green Bank radio ...

This newly discovered cloud is 3,400 times the mass of the Sun—and we almost missed it Eos may never form stars—but it’s offering a new way to see the invisible parts of our galaxy.

Hello, Eos! Recently discovered molecular cloud is believed to be one of the largest structures in the sky and among the closest to Earth and the sun.

“If you were to see this cloud on the sky, it’s enormous,” said Dr. Burkhart, who announced the discovery with colleagues in the journal Nature Astronomy.

Named Eos after the Greek goddess of the dawn, the cloud of gas would appear huge in the night sky if visible to the naked eye. It measures roughly 40 moons in width and has a weight about 3,400 ...

"This cloud is literally glowing in the dark,” Burkhart said. Burkart and her team were able to make the discovery by observing data collected by a far-ultraviolet spectrograph called FIMS-SPEAR ...
