"Matter/antimatter annihilation represents the 'ultimate' source of stored energy for space propulsion," says a November 2002 report from NASA's Marshall Space Flight Center in Alabama.

We've actually observed matter-antimatter annihilation in some extreme astrophysical environments, but only around hyper-energetic sources that produce matter and antimatter in equal amounts, such ...

There are signs of matter/antimatter annihilation, but the antimatter we see is less than 0.1% of the matter in all locations. One the one hand, ...

To particle physicists, annihilation has a different meaning. Annihilation occurs when a bit of matter meets up with its corresponding bit of antimatter. What happens is not destruction; it’s ...

When matter and antimatter collide, they annihilate each other and produce particles that have energy scientists can observe unlike the invisible dark energy. Skip to content Introducing the all ...

Just a few years later, in 1932, Carl D. Anderson produced the first anti-electrons, named positrons, in the laboratory. Today, laboratory experiments around the world create and study antimatter.

New data from NASA's Fermi Gamma-ray Space Telescope confirm a mysterious spike in antimatter annihilation, ultimately hinting at signs of dark matter particles. But the data also undermine a key ...

Antimatter is the strange, evil twin of regular matter, and it’s thought to have been mostly banished from our universe. But could it still be lurking out there in large clumps, even as stars ...

Among nearly 5,800 gamma-ray sources in the catalog, 14 points of light gave off gamma rays with energies expected of matter-antimatter annihilation, but did not look like any other known type of ...
