This Ghostly Blob of Light Is a Star Being Born

Incredible stuff, isn't it?

That little flash of light above may look like a light shining out of the ocean deep—an angler fish, perhaps?—or maybe a bad cell phone photo of the Moon. But it's far, far bigger: the light peeking out behind black clouds is evidence of a star being born.

Imaged by the Hubble telescope, the burst of light is coming from the dark cloud LDN 43, which is located in the constellation Ophiuchus some 520 light-years from Earth. NASA says the clouds, made of gas, dust, and ice, are the makings of a new star. (A larger version of the image is available here.)

In fact, the light reflected in the clouds suggests that a star has already been born. The feature is named RNO 91, and is called a "pre-main sequence star" as it's not yet started combusting hydrogen on its own. Instead, the light emitted is likely due to the star material coalescing under the force of gravity. The energy released from that compression and eventual fusion of basic elements includes visible light.

According to NASA, RNO 91 also has a ring of icy dust spanning hundreds of millions of miles around it. It's quite possible that the material in the disk could coalesce into planets, leading to the eventual formation of a new star system. Incredible stuff, isn't it?
