"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.

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.

Astronomers Detect Possible Matter-Antimatter Annihilation in Giant Space Explosion Subatomic particles colliding at nearly the speed of light may have produced a unique emission line in the ...

Although our universe is mostly normal matter, antimatter isn’t so hard to create — supernovae, black holes, and even bananas can make it.

“A kilogram of matter-antimatter annihilation releases a whopping energy that’s over 250 times greater than that of nuclear fusion and over 8 orders of magnitude (108) more than chemical ...

Using NASA's Fermi telescope, astronomers have discovered a hidden "annihilation feature" in the gamma-ray burst known as the "BOAT." It's the biggest explosion since the Big Bang ...

Neutrinos could solve an antimatter mystery : Short Wave At the beginning of the universe, annihilation reigned supreme. Equal amounts of matter and antimatter collided. There should have been ...

If dark matter annihilation is indeed a source of antimatter in the universe, antimatter could point the way to dark matter, scientists hope. Calculating the flux ...

A team of researchers scrutinizing the brightest gamma-ray burst in at least 10,000 years identified a unique emission line that it believes could reveal some extreme physics at the heart of the burst ...
