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

the researchers gathered data that helps estimate the rate at which objects in the universe are separating, thereby offering insight into the expansion of the Universe itself. Data derived from ...

The rate at which the universe is expanding, known as the Hubble constant, is one of the fundamental parameters for understanding the evolution and ultimate fate of the cosmos. However ...

Scientists use a number called the Hubble constant to describe the universe’s expansion rate. One method measures the light from stars and supernovae nearby. These are called standard candles ...

Type Ia supernovae serve as "standard candles" for astronomers, providing a consistent measure of distances, essential for calculating the universe's expansion rate. A galaxy in front of the ...
