The Nancy Grace Roman Space Telescope, set to launch at the end of August, is uniquely well-placed to help us spot any ...

Dark energy is still one of the greatest cosmic mysteries. For all the time, money and telescopes that humanity has used to uncover its nature, scientists are still asking a fundamental question: What ...

Dark energy—the term used to describe whatever is causing the universe to expand at an increasing rate—is one of the universe's greatest mysteries. The most widely accepted theory currently suggests ...

Add Yahoo as a preferred source to see more of our stories on Google. Astronomers have to use indirect evidence, like the explosions of Type Ia supernovae, to investigate the impacts of dark energy.

Dark energy is one of the greatest mysteries in modern physics, constituting nearly 70% of the universe. It differs from matter, which clumps together, and from radiation, which dilutes as space ...

The universe is expanding faster every second, and physicists still can’t fully explain why. A new study connects the force binding quarks together to the mystery of dark energy. Upcoming telescopes ...

A space telescope set to measure light from a billion galaxies is a step closer to launch next month. Technicians completed ...

For more than a century, physics has been built on two great theories. Einstein’s general relativity explains gravity as the bending of space and time. Quantum mechanics governs the world of particles ...

The Dark Energy Survey collaboration is releasing results that, for the first time, combine all of the data from an intensive six-year mapping of galaxies in the universe. The new analysis, of ...

Cosmic voids may seem like the emptiest places in the universe, stripped of matter, radiation, and even dark matter. But they’re far from nothing. Even in these vast empty regions, the fundamental ...

The universe expands faster. “Dark energy” may not be constant after all. We’ve known since 1929 that the universe is expanding, and since 1998 that it’s speeding up. The unknown force behind this ...
