JWST Could Confirm Oldest Galaxy - If It Overcomes Budget Woes

摘要

NASA's next-generation space telescope could confirm the existence of the oldest galaxy yet seen and peer back even further in time, according to researchers. Astronomers using NASA's Hubble Space Telescope announced Jan. 26 that they spotted a galaxy that formed less than 500 million years after the Big Bang, making it the oldest and farthest galaxy ever seen. While the scientists are confident in their discovery, a new instrument likely will be required to confirm the galaxy's age and existence definitively, researchers said.
