What is the meaning of International Astronomical Union?
The International Astronomical Union is a worldwide society of professional astronomers and is considered the authority for assigning names to celestial objects, whether they are planets or moons or other types of worlds, as well as surface features on them.
Where is the International Astronomical Union?
Paris
International Astronomical Union (IAU), senior body governing international professional astronomical activities worldwide, with headquarters in Paris.
How was the IAU formed?
The IAU was the result of a process that started long before World War I to encourage cooperation between astronomers all over the world, at that time primarily led by the American astronomer George Ellery Hale.
What is the IAU and when was it established?
July 28, 1919International Astronomical Union / Founded
How many constellations did the IAU identify?
88 Constellations
IAU and the 88 Constellations.
Who discovered constellations?
Almost two centuries later, the Greek astronomer Ptolemy listed the 48 Greek constellations as we know them today. These 48 formed the basis for our modern constellation system. Not only that, but Ptolemy also drew up a catalog of 1022 stars, with estimates of their brightness.
What is the role of gravity in our solar system?
The sun’s gravity pulls the planet toward the sun, which changes the straight line of direction into a curve. This keeps the planet moving in an orbit around the sun. Because of the sun’s gravitational pull, all the planets in our solar system orbit around it.
Who invented the IAU constellations?
In 1928, the International Astronomical Union (IAU) formally accepted 88 modern constellations, with contiguous boundaries along vertical and horizontal lines of right ascension and declination developed by Eugene Delporte that, together, cover the entire celestial sphere; this list was finally published in 1930.
What was the purpose of the IAU establishing 88 official constellations?
The International Astronomical Union established 88 constellations that represent a defined area of the sky. The constellations are an ancient heritage handed down for thousands of years as ways to tell stories of mythical heroes and monsters.
What does the International Astronomical Union do?
Among the other tasks of the IAU are the definition of fundamental astronomical and physical constants; ambiguous astronomical nomenclature and informal discussions on the possibilities for future international large-scale facilities.
What is the Office for astronomy outreach (OAO)?
The IAU has also established in 2012 the Office for Astronomy Outreach (OAO), a joint venture with the National Astronomical Observatory of Japan. Furthermore, the IAU has also established the Office of Young Astronomers (OYA), a joint venture with the Norwegian Academy of Sciences and Letters.
How many members does the International Union of Atomic Scientists have?
As of 2018, the Union had over 13,700 individual members, spanning 90 countries, and 82 national members. Among the key activities of the IAU is serving as a forum for scientific conferences.
What is the key activity of the IAU?
The key activity of the IAU is the organization of scientific meetings. Every year the IAU sponsors 9 international IAU Symposia. The IAU Symposium Proceedings series is the flagship of the IAU publications.
