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 ...

A survey of over 1,500 supernovas conducted by the Dark Energy Camera has placed strong constraints on the accelerating expansion of the universe. The results suggest that the mysterious force that ...

Dynamical friction. The panels depict sparse areas of the universe with dark colour and dense areas with light colour. The upper panels show the density around a galaxy if the galaxy's gravity bends ...

A group of scientists may have stumbled upon a radical new way to do cosmology. Cosmologists usually determine the composition of the universe by observing as much of it as possible. But these ...

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 ...

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 ...

At long last, all of the universe’s ordinary matter seems to be present and accounted for. Astronomers have taken a new census of matter in the universe by examining how bright flashes of radio waves ...
