Hubble photo shows a cosmic cloud making its very own bright light

The legendary Hubble telescope captured an intriguing cosmic cloud — a cloud that makes its own light.

Called an “emissions nebula,” it’s a bright cloud whose gases get excited by radiation from nearby stars, and ultimately emit light. (In other words, this isn’t starlight isn’t being reflected off the gas.)

The right side of this image, however, is darkened by a great cloud of dust, which blocks light from reaching the Hubble Space Telescope.
