TUGSAT-1, also known as BRITE-Austria and CanX-3B, is the first Austrian satellite.
 It is an optical astronomy spacecraft operated by the Graz University of Technology as part of the international BRIght-star Target Explorer programme.
Heweliusz is the second Polish scientific satellite launched in 2014 as part of the Bright-star Target Explorer (BRITE) programme.
 The spacecraft was launched aboard a Chang Zheng 4B rocket in August 2014.
 Heweliusz is an optical astronomy spacecraft built by the Space Research Centre of the Polish Academy of Sciences and operated by Centrum Astronomiczne im.
 Mikołaja Kopernika PAN; it is one of two Polish contributions to the BRITE constellation along with the Lem satellite.
 It is named after Johannes Hevelius.
UniBRITE-1 is, along with TUGSAT-1, one of the first two Austrian satellites to be launched.
 Along with TUGSAT, it operates as part of the BRIght Target Explorer constellation of satellites.
 The two spacecraft were launched aboard the same rocket, an Indian PSLV-CA, in February 2013.
 UniBRITE is an optical astronomy spacecraft operated by the University of Vienna as part of the BRIght Target Explorer programme.
The University of Vienna (German: "Universität Wien" ) is a public university located in Vienna, Austria.
 It was founded by Duke Rudolph IV in 1365 and is one of the oldest universities in the German-speaking world.
 With its long and rich history, the University of Vienna has developed into one of the biggest universities in Europe, and also one of the most renowned, especially in the Humanities.
 It is associated with 15 Nobel prize winners and has been the academic home of a large number of figures both of historical and academic importance.
Connie Walker (b. 1957) is an American astronomer and senior employee of the National Optical Astronomy Observatory (NOAO).
 She works in the NOAO's Research Based Science Education department, helping teachers develop curricula to help children learn about Astronomy.
 She is the director of both GLOBE at Night and Project Astro, and is a member of the board of directors of the International Dark Sky Association and the Astronomical Society of the Pacific.
 She was also chair of the International Year of Astronomy Dark Skies Awareness project, and continues to chair the dark skies awareness programs of Global Astronomy Month.
 Walker also serves on commission 50 of the International Astronomical Union.
The National Astronomy Observatory of China (NAOC, the acronym was officially claimed as standing for National Astronomical Observatories, Chinese Academy of Sciences, ) was founded on April 25, 2001 through the merging of four CAS observatories, three CAS observing stations and one CAS research centre.
 The Headquarters of the NAOC are situated in the northern suburbs of Beijing on the site of the former Beijing Astronomical Observatory (BAO), and take responsibility for all matters relating to the former BAO.
 The reformation of management structure imitated to National Optical Astronomy Observatory (NOAO) and National Radio Astronomy Observatory (NRAO) of USA and National Astronomical Observatory of Japan (NAOJ).
Visible-light astronomy encompasses a wide variety of observations via telescopes that are sensitive in the range of visible light (optical telescopes).
 It includes "imaging", where a picture of some sort is made of the object; "photometry", where the amount of light coming from an object is measured, "spectroscopy", where the distribution of that light with respect to its wavelength is measured, and "polarimetry" where the polarisation state of that light is measured.
 An example of spectroscopy is the study of spectral lines to understand of what kind of matter light is going through.
 Visible astronomy also includes looking up at night ().
 Visible-light astronomy is part of optical astronomy, and differs from astronomies based on invisible types of light in the electromagnetic radiation spectrum, such as radio waves, infrared waves, ultraviolet waves, X-ray waves and gamma-ray waves.
A radio telescope is a specialized antenna and radio receiver used to receive radio waves from astronomical radio sources in the sky in radio astronomy.
 Radio telescopes are the main observing instrument used in radio astronomy, which studies the radio frequency portion of the electromagnetic spectrum emitted by astronomical objects, just as optical telescopes are the main observing instrument used in traditional optical astronomy which studies the light wave portion of the spectrum coming from astronomical objects.
 Radio telescopes are typically large parabolic ("dish") antennas similar to those employed in tracking and communicating with satellites and space probes.
 They may be used singly, or linked together electronically in an array.
 Unlike optical telescopes, radio telescopes can be used in the daytime as well as at night.
 Since astronomical radio sources such as planets, stars, nebulas and galaxies are very far away, the radio waves coming from them are extremely weak, so radio telescopes require very large antennas to collect enough radio energy to study them, and extremely sensitive receiving equipment.
 Radio observatories are preferentially located far from major centers of population to avoid electromagnetic interference (EMI) from radio, television, radar, motor vehicles, and other manmade electronic devices.
Lem is the first Polish scientific artificial satellite.
 It was launched in November 2013 as part of the Bright-star Target Explorer (BRITE) programme.
 The spacecraft was launched aboard a Dnepr rocket.
 Named after the Polish science fiction writer Stanisław Lem, it is an optical astronomy spacecraft built by the Space Research Centre of the Polish Academy of Sciences and operated by Centrum Astronomiczne im.
 Mikołaja Kopernika PAN; one of two Polish contributions to the BRITE constellation along with the Heweliusz satellite.
The Korea Astronomy and Space Science Institute (KASI) is the national research institute in astronomy and space science of South Korea funded by the South Korean Government.
 Its headquarters are located in Daejeon, in the Daedeok Science Town.
 Research at KASI covers main areas of modern astronomy, including Optical Astronomy, Radio Astronomy, Space Science, and Theoretical Astronomy.
