For the first time, the Tibet ASγ Experiment has successfully measured magnetohydrodynamic (MHD) turbulence on scales below one parsec (approximately 3.3 light-years) within the gamma-ray halo ...

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 ...

It’s always amazing, and more than a little humbling, when the universe reminds us that our “common sense” is provincial, falling apart on cosmic scales. If you’re on the surface of Earth—and I’m ...

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 ...

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 ...

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 ...
