Researchers have used pulsar measurements to help uncover new information about the density of dark matter in our home galaxy. In a new study led by Rochester Institute of Technology Associate ...

The few thousand galaxies closest to us move in a vast 'bubble' that is 250 million light years in diameter, where the average density of matter is half as large as for the rest of the universe. This ...

Astronomers at the University of Zuerich, the ETH Zurich, the University of Leicester and NAOC Beijing have found large amounts of invisible “dark matter” near the Sun. Their results are consistent ...

The map, assembled with data from the Gaia spacecraft, shows how the spread of dark matter across space matches that described by the Cosmic Microwave Background. When you purchase through links on ...

Scientists have found a new way to create a crystalline structure called a 'density wave' in an atomic gas. The findings can help us better understand the behavior of quantum matter, one of the most ...

Looking back a variety of distances corresponds to a variety of times since the Big Bang. Entropy has always increased from any moment to the next, but that doesn't mean that the Big Bang began with ...
