A study provides crucial clues about how cosmic objects send accelerated particles through space. Jets coming from quasars and supernovae can send dangerous cosmic rays that hit Earth. For the first ...

Recent research has unveiled a startling revelation: our solar system is moving at a velocity that is three times faster than previously anticipated. This discovery, announced on November 14, 2025, ...

When it comes to speed limits, the ultimate one set by the laws of physics themselves is the speed of light. As Albert Einstein first realized, everyone looking at a light ray sees that it appears to ...

In a new study, Dartmouth researchers rule out a controversial theory that the accelerating expansion of the universe is an illusion. While the findings don’t explain the cosmic speed-up, they ...

A newly proposed cosmic speed limit may constrain how fast anything in the universe can grow. Its existence follows from Alan Turing’s pioneering work on theoretical computer science, which opens the ...

Fermilab: Scientists announced that the Dark Energy Survey soon expects to make a substantial leap forward in our understanding of why the universe is accelerating and the nature of dark energy.

James Miller-Jones receives funding from the Australian Research Council and the Western Australian State Government. How fast can a neutron star drive powerful jets into space? The answer, it turns ...

The motion of any object is relative. On Earth we tend to ignore that, because the vast background of the ground gives us a seemingly fixed and absolute frame of reference. Sitting comfortably at our ...

Construction is accelerating on a $17 million cosmic ray observatory west of Delta, Utah, thanks to two U.S. agencies: the Bureau of Land Management issued a permit, and the National Science ...
