Physicists at LHC announce the discovery of Higgs boson

The existence of the boson was first suggested in 1960s. It is the force carrier in so called Higgs field, a fundamental field of crucial importance to particle physics theory. The question of the existence of the Higgs field and Higgs boson was the last unverified part of the Standard Model of particle physics.

NASA's Pathfinder space probe lands on the surface of Mars

Launched in 1996 by NASA aboard a Delta II booster a month after the Mars Global Surveyor was launched, it landed in 1997 on Mars's Ares Vallis, in a region called Chryse Planitia in the Oxia Palus quadrangle. The lander then opened, exposing the rover which conducted many experiments on the Martian surface.

Mars Pathfinder lands

The probe consisted of a lander and a robotic rover named Sojourner. It was the first rover outside of the Earth–Moon system. Although planned to last only for one week, Sojourner was active for 83 Martian days. The mission analyzed Martian atmosphere, climate, geology and the composition of its rocks and soil.

Marie Skłodowska-Curie dies of radiation poisoning

Curie died at the Sancellemoz Sanatorium in Passy, Haute-Savoie, from aplastic anemia believed to have been contracted from her long-term exposure to radiation. The damaging effects of ionizing radiation were not known at the time of her work, which had been carried out without the safety measures later developed.
