Meudon Great Refractor (also known as the Grande Lunette ) is a double telescope with lenses (83 cm + 62 cm), in Meudon, France . It is a twin refracting telescope built in 1891, with one visual and one photographic, on a single square-tube together on an equatorial mount , inside a dome. The Refractor was built for the Meudon Observatory, and is the largest double doublet (twin achromat) refracting telescope in Europe, but about the same size as several telescopes in this period, when this style of telescope was popular. Other large telescopes of a similar type include the James Lick telescope (91.4), Potsdam Great Refractor (80+50 cm), and the Greenwich 28 inch refractor (71.1 cm).

The National Museum of Natural History , known in French as the Muséum national d'histoire naturelle ( MNHN ; French: [myzeɔm nɑsjɔnal distwar natyʁɛl] ), is the natural history museum of France and a grand établissement of Sorbonne Universities . The main museum is located in Paris , on the left bank of the Seine . It was established in 1635 by King Louis XIII as the royal garden of medicinal plants, and in 1793, after the Revolution, it was reorganized in its present form and under its present title. As of 2017, the museum has 14 sites throughout France, including the original location at the Jardin des Plantes , which remains one of the seven departments of MNHN.
The Natural History Museum of Los Angeles County is the largest natural and historical museum in the western United States . Its collections include nearly 35 million specimens and artifacts and cover 4.5 billion years of history. This large collection is comprised not only of specimens for exhibition, but also of vast research collections housed on and offsite.

A CubeSat ( U-class spacecraft ) is a type of miniaturized satellite for space research that is made up of multiple cubic modules of 10 cm × 10 cm × 10 cm size. CubeSats have a mass of no more than 1.33 kilograms (2.9 lb) per unit, and often use commercial off-the-shelf (COTS) components for their electronics and structure. CubeSats are put into orbit by deployers on the International Space Station , or launched as secondary payloads on a launch vehicle . As of 1 January 2021 , more than 1350 CubeSats have been launched. More than 1200 have been successfully deployed in orbit and more than 90 have been destroyed in launch failures.
Astrophysics is a science that employs the methods and principles of physics in the study of astronomical objects and phenomena. Among the subjects studied are the Sun , other stars , galaxies , extrasolar planets , the interstellar medium and the cosmic microwave background . Emissions from these objects are examined across all parts of the electromagnetic spectrum , and the properties examined include luminosity , density , temperature , and chemical composition. Because astrophysics is a very broad subject, astrophysicists apply concepts and methods from many disciplines of physics, including classical mechanics , electromagnetism , statistical mechanics , thermodynamics , quantum mechanics , relativity , nuclear and particle physics , and atomic and molecular physics .
