University of Arizona researchers are among a group of scientists who hope to discover what happened immediately after the Big Bang, when the universe expanded in a fraction of a ...

The fate of the universe hinges on the balance between matter and dark energy: the fundamental ingredient that drives its ...

The Dark Energy Spectroscopic Instrument (DESI) is mapping millions of celestial objects to better understand dark energy—the ...

The findings suggest that dark energy is dynamic and changes over time, and that it used to be stronger in the early stages of the universe but is weaker now. That’s particularly odd because most ...

New results from the Dark Energy Spectroscopic Instrument (DESI) suggest that the unknown force accelerating the expansion of ...

If our 13.8 billion-year-old cosmos could be considered middle-aged, researchers note these new images captured around its ...

The universe has been expanding ever since the Big Bang almost 14 billion years ago, and astronomers believe a kind of ...

Our current best theories of the universe suggest that dark energy is making it expand faster and faster, but new ...

The largest-ever three-dimensional map of the cosmos, plotting out some 15 million celestial objects, could help reveal the ultimate fate of the universe. Astrophysicists know that the universe is ...
