Cosmic microwave background data support cosmology’s standard model but retain a mystery about the universe’s expansion rate.

The finest ever map of the cosmic microwave background - the faint evidence of the universe's early form - has yielded ...

His research focused on spiral galaxies and the direction in which they rotate. Logically, their spin should be evenly ...

The Hubble constant is one of the most important numbers in cosmology because it tells us how fast the universe is expanding, which can be used to determine the age of the universe and its history. It ...

For years, scientists have used a well-established model to explain how the universe evolves. The standard theory, called the ...
