Glow-in-the-dark cloud hiding near Earth?!

Astronomers just found a gigantic, glow-in-the-dark hydrogen cloud called Eos lurking only 300 light-years from Earth. It’s so big it would stretch across 40 full moons in the sky, but it’s been hidden this whole time because it doesn’t have the usual chemical markers. Scientists spotted it by its faint hydrogen glow—literally glowing in the dark! This could mean there are way more hidden clouds out there, just waiting to be discovered.
