New supercomputer simulations hint that dark energy might be dynamic, not constant, subtly reshaping the Universe’s structure. The findings align with recent DESI observations, offering the strongest ...

For nearly a century, astronomers have known that the universe is expanding. In the late 1990s, two independent teams, the ...

The universe’s expansion might not be accelerating but slowing down, a new study suggests. If confirmed, the finding would upend decades of established astronomical assumptions and rewrite our ...

This dark energy project was meant to map just a portion of the skies over a five-year period, but it performed even better and faster than expected.

In a new study, scientists began pondering a pretty wild question: What if black holes can convert dead star matter into dark energy, the mystery force driving the acceleration of the expansion of the ...

In the Big Bend region, a portal to the early universe is enabled by the largest dark-sky reserve on Earth. The Hobby-Eberly Telescope at the McDonald Observatory in Fort Davis, Texas, was used to ...

The accelerating expansion of the universe is usually explained by an invisible force known as dark energy. But a new study suggests this mysterious ingredient may not be necessary after all. Using an ...

In a significant milestone, the Dark Energy Spectroscopic Instrument (DESI) has completed its 3D map of the Universe—the highest resolution of any such map yet achieved—on schedule and with more data ...
