The James Webb Space Telescope is the most powerful telescope ever put into space. As such, its helping usher in a new era of astrophysics. Astronomers can now study farther, earlier galaxies than ever before.
"If you were a paleontologist, you would dig deeper and deeper to find the oldest bones. In astronomy, what we do is look at our history," says Jorge Moreno, an associate professor of astronomy at Pomona College. "We have to look back in time, but we don't have a time machine. So what we do is we look at really faraway distances."

"It's a galactic controversy that has astronomers around the world excited — and puzzled. So what is it about these galaxies that is getting astronomers worked up? Not only is JWST finding galaxies forming 200-500 million years after the Big Bang, but also that they are bigger and brighter than astronomers expected."
