Velocity streamlines within the reconstructed volume, with colored envelopes associated with the prominent nearby basins of attraction. The map and streamlines have been cropped to the region covered ...

Astronomers have long struggled with a troubling puzzle: a significant portion of normal matter in the universe appeared to be missing. Scientists knew this matter had to exist based on predictions ...

Astronomers have identified a vast, twisting chain of galaxies that appears to be rotating as a single structure, a kind of cosmic tornado that stretches across tens of millions of light years. If ...

Scientists estimate that dark matter and dark energy together are some 95% of the gravitational material in the universe while the remaining 5% is baryonic matter, which is the “normal” matter ...

Numerical simulations provide a mechanism that explains how celestial objects such as stars and galaxies can generate ordered, macroscopic magnetic fields. The mechanism arises from turbulence — ...

A new survey of hot, X-ray-emitting gas in the Virgo galaxy cluster shows that the elements needed to make stars, planets and people were evenly distributed across millions of light-years early in ...

Recent studies suggest that our galaxy, the Milky Way, may be situated in a cosmic void, a revelation that could potentially resolve some complex cosmological mysteries. The exploration of these ...
