Antimatter was discovered in 1928 by Paul Dirac.
That is not currently known. There is a slight assymetry between matter and antimatter, but so far, it seems that this assymetry is not enough to explain why there is only matter, and hardly any antimatter, in the Universe. Without such an assymetry, there wouldn't be either matter or antimatter in the Universe - just radiation. For more information about what is known, and what isn't, check the Wikipedia article on "Baryon asymmetry".
It was discovered in 1850s

The amount of planet matter equal to that of the astronaut would annihilate.
Antimatter was discovered in 1928 by Paul Dirac.
Antimatter was discovered by Paul Dirac in 1928.
The existence of antimatter was first predicted by physicist Paul Dirac in 1928 as a consequence of his Dirac equation, which unified quantum mechanics and special relativity. The first observation of antimatter particles, specifically positrons, was made by physicist Carl D. Anderson in 1932 while studying cosmic rays.
The first synthesis of antimatter was achieved by Carl D. Anderson in 1932 when he discovered the positron, which is the antimatter counterpart to the electron. Anderson's discovery provided experimental evidence for the existence of antimatter.

Yes, antimatter has been experimentally observed through the creation and study of antiparticles such as the positron (antielectron) and antiproton. These antiparticles have properties opposite to their normal matter counterparts, providing evidence for the existence of antimatter.
Karl Trek, although i could be wrong im not completely sure if antimatter has been discovered because when it hits matter they cancel out...but its said antimatter is used in PET scans
They can DEFINITELY breathe antimatter
It was discovered in 1898.
Antimatter - band - was created in 1998.
Antimatter - album - was created in 1993.
No, antimatter does not possess negative mass. Antimatter has the same mass as regular matter, but opposite charge.
