For example, the light-second, useful in astronomy, telecommunications and relativistic physics, is exactly 299 792 458 metres or 1 / 31 557 600 of a light-year. Units such as the light-minute, light-hour and light-day are sometimes used in popular science publications.
The International Space Station is a platform for scientific research that requires one or more of the unusual conditions present in low Earth orbit (for example microgravity, -radiation and extreme temperatures). The primary fields of research include human research, space medicine, life sciences, physical sciences, astronomy and meteorology.
A year later, during the fourth EVA of mission STS-118 on 18 August 2007, the MISSE-3 and 4 experiments were retrieved. [12] MISSEs 3 and 4 also served an educational purpose, it flew approximately eight million basil seeds that were given to children for science experiments, in order to stimulate interest in space science.

Cavendish experiment (1798): Henry Cavendish's torsion bar experiment measures the force of gravity in a laboratory. Double-slit experiment (c.1805): Thomas Young shows that light is a wave in his double-slit experiment.
A potentially habitable exoplanet that is roughly similar in size to Earth has been found in a system located 40 light-years away, according to a new study. ... Science & Tech. Sports. Weather. 24 ...
Breakthrough Starshot is a research and engineering project by the Breakthrough Initiatives to develop a proof-of-concept fleet of light sail interstellar probes named Starchip, [1] to be capable of making the journey to the Alpha Centauri star system 4.34 light-years away. It was founded in 2016 by Yuri Milner, Stephen Hawking, and Mark ...
The Sanford Underground Research Facility (SURF), or Sanford Lab, is an underground laboratory in Lead, South Dakota. The deepest underground laboratory in the United States, it houses multiple experiments in areas such as dark matter and neutrino physics research, biology, geology and engineering. There are currently 28 active research ...
Additionally, some such exoplanets may exist only 13 light-years from Earth. [97] Scientists discover live bacteria in the subglacial Antarctic Lake Whillans. [98] 8 February Scientists use an extensive genetic and phenotypic database to determine the common ancestor of all modern placental mammals, including humans. [99] [100] [101]
