*Map of the Constellations by Dominic Ford*

*The Orion Nebula as seen by the Hubble Telescope*

Hoewel erg mooi en goed zichtbaar aan het zuidelijk firmament, want lang donker, is de Orionnevel en het Orion sterrenbeeld niet mijn favoriete constellatie, want op het noordelijk halfrond is het dan winter.
En ik woon in Nederland en houd van de lente. In de loop van die lente verdwijnt Orion uiteindelijk in het zuidwesten onder de horizon¹.
Dus zie ik bijvoorbeeld toch liever de minder karakteristieke Centaurus constellatie omdat het dan in Europa lente of zomer is.

Astronomy • Magazine
Get to know Astronomy magazine. The world’s most popular magazine covering astronomy, observing, and spaceflight news. Little did Steve Walther know that his brainchild would turn into the greatest magazine about astronomy in the world. At 29, the ambitious graduate of the University of Wisconsin-Stevens Point launched a periodical about his first love, the stars. The first issue, August 1973, held 48 pages and five feature articles, plus information about what to see in the night sky that month. Since its inception, Astronomy magazine has grown thanks to the great people behind it. Dedicated by an obsession with the subject of astronomy, they are driven to assemble the best, most-absorbing material relating to the world of astronomy with every page they have. Names such as Walther, Berry, Maas, and Burnham long ago established the magazine’s stable foundation. And the names you see in the magazine today will carry on their tradition of excellence.
Astronomy • Wikipedia
This article is about the scientific study of celestial objects. For other uses, see Astronomy (disambiguation). Not to be confused with astrology, a pseudoscience.. Astronomy (from Greek: ἀστρονομία, literally meaning the science that studies the laws of the stars) is a natural science that studies celestial objects and phenomena. It uses mathematics, physics, and chemistry in order to explain their origin and evolution. Objects of interest include planets, moons, stars, nebulae, galaxies, and comets. Relevant phenomena include supernova explosions, gamma ray bursts, quasars, blazars, pulsars, and cosmic microwave background radiation. More generally, astronomy studies everything that originates beyond Earth's atmosphere. Cosmology is a branch of astronomy that studies the universe as a whole. Astronomy is one of the oldest natural sciences. The early civilizations in recorded history made methodical observations of the night sky. These include the Babylonians, Greeks, Indians, Egyptians, Chinese, Maya, and many ancient indigenous peoples of the Americas. In the past, astronomy included disciplines as diverse as astrometry, celestial navigation, observational astronomy, and the making of calendars. Nowadays, professional astronomy is often said to be the same as astrophysics.[2] Professional astronomy is split into observational and theoretical branches. Observational astronomy is focused on acquiring data from observations of astronomical objects. This data is then analyzed using basic principles of physics. Theoretical astronomy is oriented toward the development of computer or analytical models to describe astronomical objects and phenomena. These two fields complement each other. Theoretical astronomy seeks to explain observational results and observations are used to confirm theoretical results. Astronomy is one of the few sciences in which amateurs play an active role. This is especially true for the discovery and observation of transient events. Amateur astronomers have helped with many important discoveries, such as finding new comets.

Carl Sagan • was a celebrity, scientist, and star of the original Cosmos: A Spacetime Odyssey, but who was the real Carl Sagan?
Cosmos: A Spacetime Odyssey will invent new modes of scientific storytelling to reveal the grandeur of the universe and re-invent celebrated elements of the original series, including the Cosmic Calendar and the Ship of the Imagination. Uniting scepticism and wonder, and weaving rigorous science with visual, emotional and spiritual elements, it will be a transcendent experience – a vision of the cosmos on the grandest scale we know.
Constellation Guide • Constellations: A Guide to the Night Sky
The constellations in tonight’s sky host many familiar star patterns. For northern observers, spring is the best time of the year to see the Big Dipper in Ursa Major, the Little Dipper in Ursa Minor, and the Kite in Boötes. Observers in the southern hemisphere can catch the stars and deep sky objects around the Southern Cross, the Fish Hook in Scorpius, and the Teapot in Sagittarius. The night sky tonight looks different depending on the location.
Cosmos: A Personal Voyage • Carl Sagan
Cosmos: A Personal Voyage is a thirteen-part, 1980 television series written by Carl Sagan, Ann Druyan, and Steven Soter, with Sagan as presenter.

European Southern Observatory (ESO) • enables scientists worldwide to discover the secrets of the Universe for the benefit of all.
About ESO The European Southern Observatory (ESO) enables scientists worldwide to discover the secrets of the Universe for the benefit of all. We design, build and operate world-class observatories on the ground. Astronomers worldwide use our telescopes to tackle exciting questions and spread the fascination of astronomy: How did the Universe come into existence? What are black holes? Are we alone in the Universe? We are an intergovernmental organisation established in 1962 supported by 16 Member States (Austria, Belgium, the Czech Republic, Denmark, Finland, France, Germany, Ireland, Italy, the Netherlands, Poland, Portugal, Spain, Sweden, Switzerland and the United Kingdom), our host country Chile and strategic partners. ESO brings together over 750 staff from more than 30 countries, and countless more collaborators worldwide, all driven by the passion to build the best telescopes, serve the community and benefit society. We are humbled by the privilege to serve more than 22 000 users from over 130 different countries with excellent infrastructure, services, technologies and data. All our telescopes are currently located in the Chilean Atacama Desert, a marvelous place with unique conditions to observe the sky. ESO operates three observing sites in Chile: La Silla, Paranal and Chajnantor. In addition, we are building “the world’s biggest eye on the sky”—ESO’s Extremely Large Telescope, located on Cerro Armazones, which will be operated as part of the Paranal Observatory. At La Silla, ESO’s first observatory, we operate two of the most productive 4-metre-class telescopes in the world. Paranal is the home of ESO’s Very Large Telescope (VLT), one of the most advanced optical telescopes in the world, and its unique Very Large Telescope Interferometer (VLTI), as well as two survey telescopes, VISTA and VST. In the future, Paranal will also host and operate the Cherenkov Telescope Array (CTA) South, the world’s largest and most sensitive gamma-ray observatory. Collaboratively with international partners, ESO operates APEX and ALMA on the Chajnantor plateau. ALMA allows scientists to investigate the Universe in the millimetre and submillimetre wavelength range of light. ESO’s Headquarters are located in Garching, close to Munich in Germany. Here we conceive and develop cutting-edge telescope technologies together with our industry partners, and educate both children and adults in our visitor centre and planetarium, the ESO Supernova. Our central offices in Santiago are the hub from which we support the organisational operations in the country and collaborate with our host and partner country, Chile, its authorities, scientific community and society.

WIKISKY • Astronomical, astrophysical, and other information about space objects and astrophysical facts
main purpose of WIKISKY is to consolidate astronomical, astrophysical and other information about different space objects and astrophysical facts. We hope to achieve this purpose using the principle of visualization. When a person reads an article about a star, the star is only the abstraction for that reader. The person cannot emotionally feel the reality of the star without actually seeing it. We strive to create an extremely detailed sky map to help everybody to better understand the information gathering about any space object and various phenomena connected with those space objects. There is the list of the functions that have already been implemented in our system: The system can display about 500 millions the space objects of the star sky. Information on every object maybe complemented and edited. There is an easy search of the objects in place. The users can upload the photographs of the districts of the star sky and integrate the objects on the map with the objects on the photographs. The first version of API is implemented. In present moment we continue to work on the following elements of the system: The additional catalogues of the objects should be included in the system. The system will reflect galaxies, nebulas, and invisible in optical diapason objects. The objects will be integrated into the different groups. The priority system will be implemented. It will allow assignments of moderators. A moderator should be a specialist who can receive administrative access to the objects of his interest. The enhanced search will carry out the complex retrieval and look-up of the objects. The result of the search can be put on the map or retained locally as a text file. We would like to include more functions in our system. These functions should be useful for specialists. Some of the functions will carry out statistical or other analyses of samplings. Other functions might not be connected to the objects at all. We would require the assistance of specialists to accomplish our ambitious plans. If you would like to help, please do not hesitate to email or call us.
