Back in the 1960s, Frank Drake, an American astrophysicist and astrobiologist, proposed an equation aimed at estimating the ...

Determining the expansion rate of the universe, the "Hubble constant," shapes our understanding of the cosmos, its age, and its fate.

The idea of dark energy, a mysterious force thought to be responsible for the accelerated expansion of our universe, is being ...

Learn how Hubble is measuring the expansion rate of the Universe in this new explainer from NASA's Goddard Space Flight ...

Astrophysicists are currently struggling to explain an inconsistency that has become a cosmological crisis, and it has to do ...

Physicists have long grappled with the question of why the universe was able to support the evolution of intelligent life.

Astronomers studying the accelerating expansion of the universe have found that dark energy, the force thought to be ...

The DESI collaboration's latest research supports the standard model of gravity and hints at evolving dark energy, based on a ...

Since the discovery of the acceleration, theorists have calculated that the universe will continue to expand faster and faster — until the cosmos becomes (trillions of years later) utterly cold, dark ...

A compound lens forged by two galaxies is helping astronomers get a bead on the Hubble Constant and dark energy.

The most popular model for dark energy suggests it is the cosmological constant, which describes the intrinsic energy of empty space that is powering the acceleration of the expanding universe.
