Webb's measurements provide new light on a decade-long mystery known as the Hubble voltage - the differences in the age of the universe between the Hubble observations and past observations that remain unexplained * Prof. Adam Ries, winner of the Nobel Prize in Physics for the discovery of dark energy heads the project
An example of a supernova detected by the Dark Energy Survey within the field covered by one of the few detectors in the Dark Energy Camera. The supernova exploded in a spiral galaxy with redshift = 0.04528, which corresponds to a light travel time of about 0.6 billion years. For comparison, the quasar on the right has a redshift of 3.979 and a light travel time of 11.5 billion years. Credit DES Collaboration/NOIRLab/NSF/AURA/M.

The Dark Energy Survey publishes final results from the largest, in-depth and uniform sample of supernovae

Among the observations of about two million distant galaxies, the researchers found several thousand supernovae, and this is the largest and deepest sample of supernovae ever obtained with a single telescope. The scientists then used advanced machine learning techniques to help classify the supernovae

The experiment that challenges dark energy

A group of researchers from Nanjing University and the University of Science and Technology of China developed an experiment that tested a model for dark energy. The results of the experiment ruled out the model in question that predicted a fundamental fifth force in nature.

Dark energy is the name given by scientists to the phenomenon that causes acceleration in the expansion of the universe. There are three different hypotheses about the nature of dark energy: it may be a constant energy that arises from empty space itself (the hypothesis of the cosmological constant), or it may be a variable energy that originates from a fundamental field found in all of space. But it is also possible that dark energy does not exist at all and that the reason for the acceleration of the universe's expansion is that gravity behaves in a different way than our theories say when it comes to ranges on a cosmic scale.

The dark energy puzzle

The "Einstein Ring", as photographed by the Hubble Space Telescope, is a phenomenon of gravitational collapse. When a massive mass passes on one axis between a more distant celestial gram and the Earth, the light rays of the more distant gram are bent around the massive mass and form a ring known as the "Einstein Ring" from the perspective of the observer on Earth. Examining slight changes in the gravitational clouding will allow the detection of planets around a star that creates such clouding. Source: NASA.
