Spectacular scenes show two galaxies having a ‘cosmic joust’. Astronomers have witnessed for the first time a violent space collision in which one galaxy pierces another with intense radiation.

All the latest science news on cosmic background radiation from Phys.org. Find the latest news, advancements, and breakthroughs.

New research by the Atacama Cosmology Telescope (ACT) collaboration has produced the clearest images yet of the universe's infancy—the earliest cosmic time yet accessible to humans. Measuring ...

Matter in intergalactic space is not randomly scattered - it forms a vast network of filamentary structures that make up the ...

New research has unveiled images of the universe in its infancy—a mere 388,000 after the Big Bang. ... The image shows the cosmic microwave background radiation visible 380,000 years after the ...

If the universe had holes—and therefore also loops—this fact should be reflected in the data of the cosmic background radiation. Yet in searches from the 2000s and 2010s, experts found nothing.

Detection of cosmic effect may bring universe's formation into sharper focus. A project initiated at Princeton made the first observation of a cosmic effect theorized 40 years ago that could provide ...

This afterglow—the "cosmic microwave background" (CMB), the relic radiation left behind by the Big Bang—has given astronomers insights into the birth of the universe and helped shape the ...

About half of the non-dark matter in the universe cannot be accounted for by stars and galaxies alone. Now, scientists say previously undetected clouds of hydrogen gas could finally reveal it.

The rate of cosmic expansion tells us how old the universe is — about 13.8 billion years according to the current estimate based on the background radiation. And cosmic expansion will ultimately ...
