A gamma-ray pulsar
Paul discovered gamma rays, which refers to electromagnetic radiation of an extremely high frequency and are therefore high energy protons. Gamma rays are ionizing radiation, and thus harmful to human beings.

How did he discover that?
Who on Earth was he?
Paul discovered that the radiation from radium salts had exposed a photographic plate through a shielded container, despite a thin layer of lead thought to shield against the forms of radiation known then (alpha and beta radiation). He then found that the remaining type of radiation was something novel.
Paul was a French chemist and physicist who was born on the 28th of September, 1860, in Saint-Germain-au-Mont-d'Or, Rhône. He worked in Paris at the same time as Marie and Pierre Curie, and discovered gamma rays in 1900.
