James Webb Telescope Confirms the Universe Is Expanding Faster Than We Thought—and Scientists Still Don’t Know Why
Astronomers have long understood that the universe is expanding—in other words, the space in between cosmic objects that aren’t bound by gravity is getting ever more vast. Then, in 1998, scientists discovered the universe’s rate of expansion is accelerating.
Phantom Galaxy Seen Through James Webb and Hubble Telescope
The Phantom Galaxy (M74) has been imaged in infrared and optical light using the James Webb Space Telescope and Hubble Space Telescope. The spiral galaxy is about 32 million light-years from Earth. Credit: Space.
James Webb telescope confirms we have no idea why the universe is growing the way it is
Astronomers can't agree how fast our cosmos is expanding. A new James Webb Space Telescope study has made the crisis even worse.
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.
New Webb Telescope Discovery Challenges Cosmic Theory
Recent observations from the James Webb Space Telescope (JWST) challenge the previously held cosmic theory on the universe's expansion.
Cracks in cosmological theory: James Webb telescope is challenging what we know about the universe
When the James Webb Telescope came online in 2021, it promised to give a clearer picture of the universe that could help cosmologists better measure some of these distances and therefore the expansion rate. But the high-resolution images thus far have confirmed that the tension persists.
Webb Telescope Confirms Hubble Constant, Challenging Crucial Cosmic Theory
These instruments, like the Hubble Space Telescope, reported a value of around 73 km/s/Mpc. The difference between these numbers is known as the Hubble Tension. "The discrepancy between the observed expansion rate of the universe and the predictions of the standard model suggests that our understanding of the universe may be incomplete,
NASA’s James Webb Telescope uncovers unexpected mysteries of the universe
New observations from the James Webb Space Telescope have reinforced the Hubble tension, a discrepancy between different measurements of the universe's expansion rate. Scientists, using Cepheid variable stars,
