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

Physicists have been puzzling over conflicting observational results pertaining to the accelerating expansion rate of our Universe—a major discovery recognized by the 2011 Nobel Prize in Physics. New ...

Our universe appears to be expanding about eight percent faster than initially assumed possible, according to new observations from the James Webb Space Telescope. There has been a long-established ...

Most explanations rely on "dark energy" to explain the Universe's accelerating expansion rate, but a new study takes a different path.

If recent discoveries that dark energy is evolving hold any water, our Universe will collapse under its own gravity on a ...

A representation of the evolution of the universe over 13.77 billion years. NASA's Goddard Space Flight Center Astronomers have long understood that the universe is expanding—in other words, the space ...

Cosmic inflation tries to describe one brief but crucial phase in the Big Bang that launched the universe onto its expansion course. Many textbooks and science educators have attempted to describe the ...

This week, researchers published LIGO findings that hint at the existence of second-generation black holes. Astronomers ...
