The antiproton was produced when protons from a cyclotron were used to bombard a copper target.
Soon, we produced antiprotons in accelerators and finally, in 1995, we combined a positron with an antiproton to produce an antimatter atom.
Antimatter is matter composed of antiparticles, such as positrons, antineutrons and antiprotons.
The antiprotons - which are negatively charged, like electrons - took up orbits around nuclei.
Positrons, antiprotons and other antiparticles can be routinely created at particle accelerator labs and can even be trapped and stored for days or weeks at a time.
