We still don't fully understand what triggers lightning. A new study suggests that showers of cosmic rays may be the missing ...

When matter and antimatter meet, they annihilate each other ... In Washington last week, Navy scientists reported that a high-flying Aerobee rocket had detected strong X-ray sources associated ...

Antimatter, as we know it today ... Considering the incredible inefficiency of even the best chemical rocket propellants today, two kilograms of fuel for a trip into space is a lot more manageable ...

According to a 2003 report prepared by Frisbee for the 39th AIAA/ASME/SAE/ASEE Joint Propulsion Conference and Exhibit, a two-stage antimatter rocket would need more than 900,000 tons (815,000 ...

A new analysis of astronomical data suggests unknown physics is at work assisting dark energy in acting almost as ...

(via Fermilab) Scientists study antimatter, investigating the ways in which it acts like ordinary matter and the ways in which it differs. Antimatter is the opposite of ordinary matter and, when ...

Anyone ready for a very special and historic late-night rocket launch? Fram2, a private SpaceX spaceflight mission, is set to be the first human spaceflight mission to orbit around Earth's poles.

Physicists have, for the first time, seen a matter particle from the proton family behave in a fundamentally different way from its antimatter twin. The finding — which fits with behaviours ...

“We needed a machine like the LHC capable of producing a large enough number of beauty baryons and their antimatter counterparts, and we needed an experiment at that machine capable of pinpointing ...

However, a new U.K.-based company is claiming that its fusion-powered rocket, called “sunbird” could be ready for space-based demonstration by as early as 2027. Designed to be a space ...
