First results from the Dark Energy Spectroscopic Instrument offer hints of new physics.
Something else is influencing the expansion rate of the Universe.
Gravitationally lensed images of two different supernovas in the same galaxy can be used to measure the expansion rate of the universe.
Last month, astronomers focused the Webb Space Telescope on the galaxy MRG-M0138 and found something surprising: a supernova in the ancient universe, magnified for your viewing pleasure by the gravitational lensed galaxy.
Astronomers found two supernovae in one galaxy, only a few years apart. This is an unprecedented opportunity to measure the Hubble Constant.
