On a clear night, you'll probably see a lot of stars when you look up at the sky. While it is amazing that some of them are millions of light years away, scientists are excited about something even further away! They have discovered something massive lurking at the very edge of the universe, thanks to the new James Webb Space Telescope! What have scientists discovered? How did the JWST contribute to its discovery, and does the object have any impact on our planet? Join us as we explore the massive objects discovered on the outskirts of the universe by the James Webb Space Telescope! There were many unknowns about the universe when scientists planned and designed the Hubble Space Telescope, the most groundbreaking astronomical observatory of its time. One of these unknowns was the existence of stars and galaxies a few hundred million years after the Big Bang. Even if they were aware of these early stars and galaxies, they lacked the technology to make Hubble see them. Science had moved on by the time they built it, and science had changed in some ways. And, in the 1980s [shortly before Hubble's 1990 launch], astronomers discovered that galaxies formed much earlier than expected. It became clear that another, even larger, space observatory would be required to reach those early stars and galaxies, which had lit up the universe after hundreds of millions of years of darkness following the Big Bang, when the expanding space was only filled with hydrogen atoms.
