What we saw in the DESI experiments, and now strengthened by our South Pole Telescope observations, is that dark energy is ...

A festinating new theory shifts focus from space to time, arguing the clock-ticking we take for granted is richer and weirder ...

Chi Nguyen remembers the moment she plugged her laptop into a large monitor in a conference room and onlookers began to cheer ...

This is the first significant improvement in cosmic microwave background radiation measurements since the Planck satellite dataset set the standard a decade ago. Taken together, the DESI and South ...

The first ever space telescope, the Orbiting Astronomical Observatory 2 (OAO-2), was launched into the low Earth orbit in ...

The research team developed novel analysis methods for dark energy in the study. By integrating DESI's latest measurements with supernova and cosmic microwave background radiation data, researchers ...

In the Big Bang Theory, the cosmic microwave background — microwave-range radiation that floats through the entire universe ...

The earliest galaxies may have scrambled our reading of the Universe. A new study challenges the traditional interpretation of the cosmic microwave background, this fossil light from the Big Bang.

The cosmic microwave background — the leftover light from when the universe was only 380,000 years old — soaks the entire cosmos, filling every cubic centimeter.

The CLASS telescope array has taken a fresh look at the infant universe to hunt for polarized light in the Cosmic Microwave Background that resembles light bouncing off a cosmic car hood.
