The clearer data and images from ACT are also helping scientists ... The collaboration measured the polarization of light from the cosmic microwave background (CMB). That's the faint microwave ...

"This shocking result means that we now need to revisit the very foundations of everything we know about cosmology," said the reseachers.

The image shows the cosmic microwave background radiation visible 380,000 years after the Big Bang. The image shows the cosmic microwave background radiation visible 380,000 years after the Big Bang.

Using antennae, scientists first identified the cosmic microwave background in the 1960s. Since then physicists have built more and more sophisticated instruments to capture increasingly better images ...

In 2015, astronomers from Caltech used the Keck Cosmic Web Imager (KCWI ... so you can take the background light from image B and subtract it from A, and vice versa, leaving just the structures.

images to identify them. They used microwaves from the Cosmic Microwave Background (CMB), which is the radiation leftover from the Big Bang, to overcome the shortage of galaxy light even further away.

The pictures, made by a scientific instrument called the Cosmic Background Imager on a desolate Andean plateau in Chile, are the most detailed images of the oldest light ever emitted, researcher said ...

In the study, “Measurement of the Cosmic Optical Background using the Long Range Reconnaissance Imager on New Horizons,” lead author Michael Zemcov used archival data from the instrument onboard New ...
