Science Just Found Secret Galaxies Hidden in Space Blobs

They'll make your mind hurt.

In the 1990s, a few Caltech buddies discovered some big, blobby lights that turned out to be glowing clouds of hydrogen gas. The blobs were so big that they were about 10 times the size of the Milky Way—so if those blobs were arrogant things, they could boast of being among the biggest known objects in the universe.

The Caltech space watchers called these big, lighted, maybe-scary unknown clouds Lyman-alpha blobs, and the brightest minds in the scientific community really had no idea what made the enormous blobs glow.

Until now, thanks to the latest and greatest telescope technology in Chile—the ALMA telescope. 

From NPR

The group found a pair of large galaxies hiding inside the blob. They couldn't be seen before because they were obscured by dust. These galaxies are producing new stars at a frantic pace—and each is making the equivalent of 100 new suns every year, says Jim Geach, an astronomer at the University of Hertfordshire in the United Kingdom.

Scientists say it’s still too early to determine what is exactly causing these giant blobs to glow, never mind spitting out 100 suns per year, but with the new research and technology, sky experts are able to paint a better picture. And it makes sense that the hidden galaxies would omit this (kind of eerie) light. Of course the physical world, out beyond what we know of it, is a spooky place!

There are galaxies hiding in blobs, in other galaxies, made of galaxy things. There are mountains beyond mountains.
