For generations, humans have gazed at the stars and wondered about the ultimate fate of the universe. Will it expand forever ...

What we saw in the DESI experiments, and now strengthened by our South Pole Telescope observations, is that dark energy is ...

Physicists have set a new upper bound on the interaction strength of dark matter by simulating the collision of two clouds of interstellar plasma. The result, from researchers at Ruhr University ...

The discovery of dark energy. From 1999 to 2004, the cosmological community came together to agree that the universe was 5% ...

What DESI is telling us is that at the point that dark energy became more influential than matter, it was in its phantom guise. “This is really weird,” says Lahav; and it gets weirder. The energy ...

Astronomers have captured a breathtaking new image of thousands of galaxies, thanks to the Dark Energy Camera (DECam) mounted on the U.S. National Science Foundation's Víctor M. Blanco 4-meter ...

New evidence suggests the universe might not behave as expected, raising questions about the costs of being wrong.

Last year, we reported on an exciting hint of new physics in the first data analysis results from the Dark Energy Spectroscopic Instrument (DESI)—namely that the dark energy, rather than being ...

The latest Dark Energy Spectroscopic Instrument results fall short of the discovery threshold but strengthen evidence for dynamical dark energy. Last year, we reported on an exciting hint of new ...

Dark energy’s implied fading, it seemed, was refusing to fade away. ... BAOs are essentially ripples from giant sound waves that coursed through the hot plasma that filled the early universe, ...

Two loops of "dark" plasma exploded from the sun on July 21, sending a stream of plasma and magnetic field known as a coronal mass ejection barreling towards Earth.

The plasma released on July 21 appears dark due to it being cooler and more dense than the sun beneath it. This plume of plasma then formed the core of a coronal mass ejection that is forecast to ...
