Let's face it: It's only a matter of time until Mars comes after us. We've got lots of water. It doesn't. We've got life. It doesn't. All this might have been okay, but then we alerted Mars to our presence with our various satellites and rovers, and now it's just a matter of time. Here are some ways we might destroy the red menace before it comes after us. More »

The Large Hadron Collider is constantly on the hunt for "new physics" — discoveries that confound and expand our current understanding of the universe... and it may have found one in the decay patterns of a subatomic particle and its antimatter counterpart. More »

Cosmic rays bring our planet a steady stream of protons, electrons, and other particles. As these collide with nuclei in the upper atmosphere, they create new particles, including antiprotons. And some of this antimatter is sticking around above our world. More »

If you're like the rest of us, you're almost certainly made of matter. But where did all that delicious, gooey matter come from? In this In this week's "Ask a Physicist" we'll find out. More »

There's nothing in the laws of physics that actually requires matter to dominate antimatter, and yet all our observations of the universe suggest that that's the case. But some unexpected behavior by ghostly neutrino particles could solve the antimatter mystery. More »

This seems like a straightforward enough question, but we actually have no idea whether gravity repels or attracts antimatter, all because we've never actually managed to trap enough antimatter at once to test it. That may be about to change. More »

The Extreme Light Infrastructure is a new project that will build three incredibly powerful new lasers. Capable of creating energy pulses 20 times more powerful than anything before, these new lasers could help us probe the world of weird physics. More »

Are we ever going to use antimatter to drive a starship? More »

Antimatter seems impossibly exotic, something that exists only in particle accelerators or in cosmic events many light-years away. But the next time there's a big thunderstorm, look up at the sky: you're looking at the creation of natural antimatter bursts. More »

Physics is still grappling with two basic questions about the nature of matter: why is there more matter than antimatter, and where and what is all the dark matter? Meet the hypothetical X particle, the potential answer to both questions. More »

Positronium is a particle created when you bind together an electron and its antimatter counterpart, the positron. It doesn't interact with other atoms in the way we would expect, and this discovery could help us solve the universe's biggest mysteries. More »

Today physicists announced that they may have found the key to explaining dark matter in the universe. It all has to do with the potential discovery of a "sterile neutrino." More »

Matter and antimatter should be of equal weight, but the results from a new experiment suggest that they aren't. More »

Here's everything you ever wanted to know about antimatter, but were afraid to ask. Or most of the things you kind of wondered about antimatter but didn't give that much of a crap about. Whichever. More »

Immediately after the Big Bang, the earliest elementary particles fought for supremacy, with matter emerging victorious over antimatter. Exactly how that happened, though, had remained mysterious until now, as new data suggest a particular particle was key to matter's success. More »

Seconds after the Big Bang, the Universe was a soup of matter and antimatter. But today, everything around us is matter. So what and where is the antimatter? Last week, scientists came one step closer to finding out. More »

Earlier today, we celebrated the discovery that antimatter can be found everywhere — not just the center of the galaxy. Now we'll take you deep inside the strange world of antimatter-powered spaceships. Believe it or not, there's actually an entire lab devoted to antimatter space propulsion at Penn State (the image you see here is their AIMstar). Once we mined a bunch of antimatter out of black hole binaries or neutron stars, though, how would we get anywhere with it? More »

When electrons and positrons collide, you've got antimatter. Previously, astrophysicists believed that this particle slam-dance could only happen in the hot, energetic heart of a galaxy. But now a new article in the latest issue of Nature reveals that antimatter is being brewed up everywhere around us — at least, everywhere with a binary star system with a black hole, or a neutron star. That means antimatter is raining down on Earth from our own little volume of space, and future antimatter miners won't have to travel to the center of the galaxy to get this potential form of fuel.
