Two international teams zoned in on a potential answer to a decades-long mystery surrounding ephemeral cosmic X-rays.

With their innovative design, tokamak reactors are leading the charge in fusion research, aiming to unlock the potential of nuclear fusion for global energy needs.

These images show the merger of two neutron stars simulated with a new supercomputer model. Red colors indicate lower-density regions. The green and white ribbons and lines represent magnetic fields.

Radioactive sources contain radioactive material of a particular radionuclide (an unstable form of an element emitting radiation), which can vary based on the application for which the source was ...

This results in the star collapsing into a dense, spinning magnetized neutron star. Their spinning magnetic fields send out beams of gamma rays, the most energetic form of light. As these beams sweep ...

Astronomers have discovered around 300 new gamma-ray-blasting pulsars, including several "spider pulsars" that devour the companion stars like black widows.

A new catalog produced by a French-led international team of astronomers shows that NASA’s Fermi Gamma-ray Space Telescope has discovered 294 gamma-ray-emitting pulsars, while another 34 suspects ...

Most people interpret radiation as a bad thing—but it isn’t always. In fact, radiation is a very normal phenomenon. For now, let’s just say that radiation is when an object produces energy.

The neutron-rich oxygen isotopes oxygen-27 and oxygen-28 exist as very short-lived resonances, report scientists from Tokyo Tech based on the first observation of their decay into oxygen-24 and three ...

Free neutrons are also produced by interactions between cosmic rays and our atmosphere, and by some of the natural radioactivity of the Earth.
