NASA's James Webb Telescope Reveals Universe Expanding Faster Than Thought
The rate of expansion of the universe today is a figure known as the Hubble constant, which is typically measured in units of kilometers per second per megaparsec (km/s/Mpc), where a megaparsec (Mpc) is about 3.26 million light-years.
James Webb Space Telescope finds smallest asteroids ever seen between Mars and Jupiter
By reverse-engineering James Webb Space Telescope (JWST) exoplanet data, a team of astronomers just spotted dozens of tiny asteroids — including the smallest ever seen in the main belt between Mars and Jupiter.

Webb telescope's largest study of universe expansion confirms challenge to cosmic theory
New observations from the James Webb Space Telescope suggest that a new feature in the universe—not a flaw in telescope measurements—may be behind the decade-long mystery of why the universe is expanding faster today than it did in its infancy billions of years ago.
