The next-gen Nancy Grace Roman Space Telescope is slated to explore vast cosmic voids to uncover the hidden forces shaping the universe.
A new interpretation of dark energy data suggests that the mysterious force, which accelerated the early universe's expansion, emerged naturally from black holes.
New data suggests the unknown, unobservable force responsible for the universe's expansion may be weakening.
A compound lens forged by two galaxies is helping astronomers get a bead on the Hubble Constant and dark energy.
The Euclid telescope had been gradually losing its vision as layers of water molecules accumulated on its mirrors.
Euclid's mission team is testing a new way to de-ice the telescope's optics and restore its ability to explore the dark universe.
Gravastars within gravastars would be a mind-blowing answer to a conundrum established by Einstein.
The Euclid space telescope, on a mission to chart the elusive dark universe, has captured its first images, revealing countless galaxies and a nearby nebula.
On Tuesday morning at 8:15 a.m. ET, we will get our first look at the images snapped by the recently launched Euclid space telescope.
The freshly launched observatory encountered a navigation issue that jeopardized its entire mission, but a software patch rectified its cosmic orientation.
Launched this past summer, the space observatory’s commissioning hasn’t been perfect, but the team remains optimistic.
The newer space observatory found that the rate of the universe’s expansion is still not adding up.
These are the first test views from Europe's new $1.4 billion space telescope. The images impress, but the operational ones promise to be even better.
