The Hubble Space Telescope has been giving us an eye in the sky since the '90s.
Now NASA is getting ready to launch Hubble's successor, the James Webb Space Telescope.
The newest Hubble frontier field image, which gazes deep into our universe to give us a look at distant galaxies, can give us an understanding of how our universe formed. Hubble took the below photo using a method called gravitational lensing.
"When you have a cluster of galaxies, light can take multiple paths around that galaxy cluster, so you see multiple images of distant galaxies," said Dr. Dan Coe, NASA Scientist. "You also see them magnified by this gravitational lens."
With the James Webb Space Telescope, NASA is going a step beyond the Hubble.
"That telescope will be even larger," Coe said. "It has a bigger mirror so it can see even more distant galaxies, fainter things. It does that by looking in the infrared, which allows us to see the universe in a whole new light. And we will be able to see the first galaxies that formed in the universe."
The James Webb Space Telescope is scheduled to launch in October 2018.
