The greatest puzzle in cosmology just got even more puzzling. Images from the James Webb Space Telescope have confirmed that the universe appears to be expanding significantly faster than it should be ...

The new study used the known distance to a galaxy called M106/NGC 4258 — a spiral galaxy in the constellation Canes Venatici — as a reference point. The universe is expanding faster than astronomers ...

Recent measurements from JWST have confirmed the validity of the “Hubble tension.” The Hubble tension stems from the fact that measuring the Hubble constant—the rate of the universe’s expansion—two ...
