For years, three cosmic phenomena have puzzled astronomers. An ultradense concentration of matter distorts the light from a ...

The finding, related to a white dwarf star that constantly extracts matter from a companion star, was published in the ...

Our planet has recently been struck by an extraordinary burst of cosmic rays, demonstrating an intensity level that is unparalleled in recorded history. As we delve into the specifics of this event, ...

As the Vera C. Rubin Observatory surveys the night sky, astrophysicists expect to unlock the secrets of dark matter, dark energy and cosmic phenomena that go “bang!” As the Vera C. Rubin Observatory ...

Astronomers have spotted the brightest fast radio burst yet coming from a nearby galaxy. Observations of this phenomenon, a powerful flash of radio waves that lasts only about a millisecond, could ...

Whenever we study space, we’re usually talking about long-lasting objects, like our own solar system or faraway galaxies that occasionally catch our attention when something extraordinary happens. But ...

Artist’s impression of an ultra-high energy cosmic ray reaching Earth. New research suggests that some of the highest-energy cosmic rays may consist of atomic nuclei heavier than iron. The background ...

Astroparticle physics explores the fundamental particles and forces at play in the Universe by studying cosmic messengers—chiefly cosmic rays, neutrinos and high-energy photons—that originate from ...

Conformal gravity theories rest on the principle of local Weyl invariance, extending general relativity by requiring invariance under pointwise rescaling of the metric. By augmenting the ...

Researchers at UBC have found a way to mimic the elusive Schwinger effect using superfluid helium, where vortex pairs appear out of thin films instead of electron-positron pairs in a vacuum. Their ...
