Getting places in space quickly has been the goal of propulsion research for a long time. Rockets, our most common means of doing so, are great for providing lots of force but are extraordinarily ...

Something is leaking out of our galaxy — and it's antimatter. According to a paper published in Astronomy & Astrophysics in July 2026, gamma-ray signals detected outside the Milky Way suggest that ...

In experiments at the Brookhaven National Lab in the US, an international team of physicists has detected the heaviest "anti-nuclei" ever seen. The tiny, short-lived objects are composed of exotic ...

Everything we see around us, from the ground beneath our feet to the most remote galaxies, is made of matter. For scientists, that has long posed a problem: According to physicists’ best current ...

Most atoms are made from positively charged protons, neutral neutrons and negatively charged electrons. Positronium is an exotic atom composed of a single negative electron and a positively charged ...

Information fills hard drives, crosses computer networks and describes the properties of physical systems. One physicist argues it may also have something far more surprising: measurable mass. Dr.

Our universe is filled with particles, such as electrons and protons, which make up all the stuff on our planet and beyond: animals, plants, people, planets, asteroids, stars, gas clouds, and galaxies ...

Add Yahoo as a preferred source to see more of our stories on Google. NASA's Fermi Gamma-ray Space Telescope discovered that thunderstorms on Earth produce antimatter. These storms also produce gamma ...
