Latest dark energy survey data suggest possible variations in dark energy over time
The U.S. National Science Foundation Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory (CTIO) in Chile, a Program of NSF NOIRLab. The Blanco is home to the 570-megapixel…
Release of Type Ia supernovae data may hold key to the history of the universe

A new view of the in-between years of our universe
A line intensity map (left) shows how galaxies are clustered in the distant past. While a high-resolution telescope (bottom right) can identify individual galaxies, a lower-resolution image (upper right) can…
We need to consider alternatives to dark matter that better explain cosmological observations

Einstein’s other theory of gravity could have the recipe to relieve ‘Hubble trouble’
An illustration of distant quasar, supermassive black hole-powered objects that can be used to constrain the parameters of theories of gravity. Credit: ESO/M. Kornmesser A recent study has investigated teleparallel…
New model suggests partner anti-universe could explain accelerated expansion without the need for dark energy
A depiction of a universe-antiuniverse pair. Credit: Wikipedia, CC The accelerated expansion of the present universe, believed to be driven by a mysterious dark energy, is one of the greatest…
The universe’s accelerated expansion might be slowing down
DESI has made the largest 3D map of our universe to date. Earth is at the center of this thin slice of the full map. In the magnified section, it…
