NASA's James Webb telescope reveals the universe as we've never seen it before

At first glance, the first image from NASA's new James Webb Space Telescope may not seem all that remarkable.

But in reality, what appears to be tiny specks in space are actually galaxies — billions of years old.

"If you held a grain of sand on the tip of your finger at arms length, that is the part of the universe you are seeing — just one little speck of the universe," NASA Administrator Bill Nelson said of the image on Monday.

And more than that, what's picked up in this image are some of the very first galaxies to form in the universe. More images captured by the James Webb Space Telescope should be able to reveal which galaxies in the far, far distance are habitable, Nelson said.
