supports: Sweden, officially the Kingdom of Sweden (Swedish: ), is a Scandinavian country in Northern Europe. It borders Norway to the west and Finland to the east, and is connected to Denmark in the southwest by a bridge-tunnel across the Öresund. At , Sweden is the third-largest country in the European Union by area, with a total population of 10.0 million. Sweden consequently has a low population density of , with the highest concentration in the southern half of the country. Approximately 85% of the population lives in urban areas. Onsala Space Observatory ( OSO ) , the Swedish National Facility for Radio Astronomy , provides scientists with equipment to study the Earth and the rest of the Universe . The observatory operates two radio telescopes in Onsala , 45 km south of Göteborg , and takes part in several international projects . Examples of activities : The 20 and 25 m telescopes in Onsala : Studies of the birth and death of stars , and of molecules in the Milky Way and other galaxies . LOFAR station : The Swedish station in the international radio telescope LOFAR is located at the observatory . VLBI : Telescopes in different countries are linked together for better resolution ( `` sharper images '' ) . ALMA , e-VLBI , Herschel Space Observatory , SKA : Developing and using new radio astronomical facilities . APEX : Radio telescope in Chile for sub-millimetre waves . Research about everything from planets to the structure of the Universe . Odin : Satellite for studies of , e.g. , the Earth 's atmosphere and molecular clouds in the Milky Way . Space geodesy : Radio telescopes ( VLBI ) and satellites ( GPS ) are used to measure movements in Earth 's crust and water vapour in the atmosphere . Receiver development : Laboratories for development of sensitive radio receivers . Onsala Space Observatory was founded in 1949 by professor Olof Rydbeck . The observatory is hosted by Department of Earth and Space Science at Chalmers University of Technology , and is operated on behalf of the Swedish Research Council . Space is the boundless three-dimensional extent in which objects and events have relative position and direction. Physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework. Halland County ("Hallands län") is a county ("län") on the western coast of Sweden. It corresponds roughly to the cultural and historical province of Halland. The capital is Halmstad. In the classical physics observed in everyday life, if something has mass and takes up space, it is said to be composed of matter; this includes atoms (and thus molecules) and anything made up of these, but not other energy phenomena or waves such as light or sound. More generally, however, in (modern) physics, matter is not a fundamental concept because a universal definition of it is elusive: elementary constituents of atoms may not take up space individually, and massless particles may be composed to form objects that have mass (even when at rest). Kungsbacka Municipality ("Kungsbacka kommun") is a municipality in Halland County on the Swedish west coast, some 30 km south of Gothenburg. The municipal seat is located in the town Kungsbacka. Time is the indefinite continued progress of existence and events that occur in apparently irreversible succession from the past through the present to the future. Time is a component quantity of various measurements used to sequence events, to compare the duration of events or the intervals between them, and to quantify rates of change of quantities in material reality or in the conscious experience. Time is often referred to as the fourth dimension, along with the three spatial dimensions. In physics, energy is the property that must be transferred to an object in order to perform work on  or to heat  the object, and can be converted in form, but not created or destroyed. The SI unit of energy is the joule, which is the energy transferred to an object by the mechanical work of moving it a distance of 1 metre against a force of 1 newton. Gothenburg is the second-largest city in Sweden and the fifth-largest in the Nordic countries. Situated by the Kattegat, on the west coast of Sweden, the city has a population of approximately 550,000 in the urban area and 990,000 inhabitants in the metropolitan area. Onsala is a locality situated in Kungsbacka Municipality, Halland County, Sweden, with 11,951 inhabitants in 2010. It is also a 14 km long peninsula on the west coast of Sweden, facing Kattegat, south of Gothenburg. It dates back to the age of the vikings and was originally an area devoted to the god Odin, the name being a corruption of the old norse "Odin's Sala". A planet is an astronomical body orbiting a star or stellar remnant that
  The term "planet" is ancient, with ties to history, astrology, science, mythology, and religion. Several planets in the Solar System can be seen with the naked eye. These were regarded by many early cultures as divine, or as emissaries of deities. As scientific knowledge advanced, human perception of the planets changed, incorporating a number of disparate objects. In 2006, the International Astronomical Union (IAU) officially adopted a resolution defining planets within the Solar System. This definition is controversial because it excludes many objects of planetary mass based on where or what they orbit. Although eight of the planetary bodies discovered before 1950 remain "planets" under the modern definition, some celestial bodies, such as Ceres, Pallas, Juno and Vesta (each an object in the solar asteroid belt), and Pluto (the first trans-Neptunian object discovered), that were once considered planets by the scientific community, are no longer viewed as such. The Universe is all of time and space and its contents. It includes planets, moons, minor planets, stars, galaxies, the contents of intergalactic space, and all matter and energy. The size of the entire Universe is unknown. The Kattegat or Kattegatt is a sea area bounded by the Jutlandic peninsula in the west, the Danish straits islands of Denmark to the south and the provinces of Västergötland, Scania, Halland and Bohuslän in Sweden in the east. The Baltic Sea drains into the Kattegat through the Danish Straits. The sea area is a continuation of the Skagerrak and may be seen as a bay of the Baltic Sea or the North Sea or, as in traditional Scandinavian usage, neither of these. In Germanic mythology, Odin (from Old Norse Óðinn) is a widely revered god. In Norse mythology, from which stems most of the information about the god, Odin is associated with healing, death, royalty, the gallows, knowledge, battle, sorcery, poetry, frenzy, and the runic alphabet, and is the husband of the goddess Frigg. In wider Germanic mythology and paganism, Odin was known in Old English as Wden, in Old Saxon as Wdan, and in Old High German as Wuotan or Wtan, all stemming from the reconstructed Proto-Germanic theonym wanaz. A star is a luminous sphere of plasma held together by its own gravity. The nearest star to Earth is the Sun. Many other stars are visible to the naked eye from Earth during the night, appearing as a multitude of fixed luminous points in the sky due to their immense distance from Earth. Historically, the most prominent stars were grouped into constellations and asterisms, the brightest of which gained proper names. Astronomers have assembled star catalogues that identify the known stars and provide standardized stellar designations. However, most of the stars in the Universe, including all stars outside our galaxy, the Milky Way, are invisible to the naked eye from Earth. Indeed, most are invisible from Earth even through the most powerful telescopes. A minor planet is an astronomical object in direct orbit around the Sun that is neither a planet nor exclusively classified as a comet. Minor planets can be dwarf planets, asteroids, trojans, centaurs, Kuiper belt objects, and other trans-Neptunian objects. As of 2016, the orbits of 709,706 minor planets were archived at the Minor Planet Center, 469,275 of which had received permanent numbers ). The Moon is an astronomical body that orbits planet Earth, being Earth's only permanent natural satellite. It is the fifth-largest natural satellite in the Solar System, and the largest among planetary satellites relative to the size of the planet that it orbits (its primary). Following Jupiter's satellite Io, the Moon is second-densest satellite among those whose densities are known.
