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 ...

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 ...

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, ...

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.

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 ...

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 ...

Astronomers watched the drama for an entire month. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. A burned-out stellar core produced a shockwave ...

The supermassive black hole at the heart of our galaxy isn't just spinning — it's doing so at almost maximum speed, dragging anything near it along for the ride. Physicists calculated the rotational ...

Here, a calcite crystal is struck with a laser operating at 445 nanometers, fluorescing and displaying properties of birefringence. Unlike the standard picture of light breaking into individual ...

Ultrahigh-energy cosmic rays twist and turn on their way to Earth, which has made it nearly impossible to identify the colossal monsters that create them. In the 1930s, the French physicist Pierre ...
