In 1991, an experiment detected the highest-energy cosmic ray ever observed. Later dubbed the Oh-My-God particle, the cosmic ray’s energy shocked astrophysicists. Nothing in our galaxy had the power ...
Ultraheavy particle clue: Penn State-led research suggests some ultrahigh-energy cosmic rays are made of nuclei heavier than iron, altering theories on their origins. Record-breaking events: The 2021 ...
A new theory suggests the universe is constantly recording its own history in the fabric of spacetime. If correct, this ...
More than one million sources of energy are featured in the first X-ray images from the eROSITA space telescope. By Laura Baisas Published Feb 5, 2024 12:00 PM EST Add Popular Science (opens in a new ...
A neutrino from space recently plunged into the Mediterranean Sea with an energy that blows all other known neutrinos out of the water. Packing a punch of some 220 million billion electron volts, this ...
Some of the most energetic cosmic rays in the galaxy may come from a surprisingly small source. If Max Planck Institute for Astrophysics researcher Laura Olivera-Nieto and her colleagues are right, ...

Dark energy is still accelerating the expansion of the universe, and astronomers are relieved
The expansion of the universe is still accelerating under the influence of dark energy, despite recent claims to the contrary ...
Dark energy may be even more complicated than scientists have bargained for, potentially “evolving” over time rather than remaining relentlessly constant in its acceleration of cosmic expansion.
There is a pattern found in nature. It is indeed the largest pattern there is. It is so vast that it spans the universe, filling up its observable volume. The pattern is made of individual units in ...
