Six years of Dark Energy Survey observations combine four cosmological probes to refine measurements of cosmic expansion, dark energy behavior, and matter clustering across billions of years.

Anaxagoras, a visionary Greek philosopher, foresaw concepts of expanding universe and multiple worlds centuries before modern science.

“You can journey to the ends of the earth in search of success,” 19th-century Baptist preacher Russell Conwell is said to have proclaimed, “but if you’re lucky, you will discover happiness in your own ...

Dark energy, the mysterious force driving the accelerated expansion of the universe, has puzzled scientists since its discovery in 1998. Despite its elusive nature, dark energy is believed to ...

The James Webb Space Telescope didn’t just peer deeper into space than ever before—it watched the universe actively stretching apart. Dark energy, that mysterious force comprising roughly 68% of ...

The Dark Energy Survey catalogued 669 million galaxies, using 140 million for precise measurements to help understand why the universe's expansion is accelerating rather than slowing down.

For centuries, people have looked to the stars, asking how it all began—and how it might end. Now, thanks to a bold new study by physicists from Cornell University, Shanghai Jiao Tong University, and ...

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 ...

A distant stellar explosion has offered astronomers a rare natural experiment, one that turns gravity into a powerful optical tool. The object, known as SN 2025wny, appears not once but four times in ...
