The galaxies IC 4635 and IC 4633 in Apus, image: Wikisky. [15] It spent much of its life as a blue-white (B-type) main sequence star before expanding, cooling and brightening as it used up its core hydrogen. Constellations were already identified by ancient civilizations and later adopted by modern astronomers - the International Astronomical Union (IAU). The celestial hemispheres are a projection of the terrestrial hemisphere into the sky. When Ukrainian troops tried retaking cities like Kherson in Russian-controlled areas in the fall, they needed internet access to communicate. He was very focused, said Mr. Sweeting, whose company later received an investment from Mr. Musk and had him on its board of directors before it sold to Airbus in 2009. It is of the 11th magnitude, and calculated to be about 59,000 light years away. = visual magnitude (m or mv), also known as apparent magnitude It has long been believed that all the stars within a globular cluster form at the about same time, a property which can be used to determine the clusters age. [4] De Houtman included it in his southern star catalogue in 1603 under the Dutch name De Paradijs Voghel, "The Bird of Paradise",[5][6] and Plancius called the constellation Paradysvogel Apis Indica; the first word is Dutch for "bird of paradise". Alpha Apodis is the brightest with a visual magnitude of 3.83.

The night sky is one of the most glorious shows that nature puts on and humans are changing it forever, said Patrick Seitzer, an astronomer at the University of Michigan who studies orbital debris. It first appeared on a 35-cm (14in) diameter celestial globe published in 1598 in Amsterdam by Plancius with Jodocus Hondius. One of the driving forces behind this behavior is thought to be gravity: more massive globulars manage to grab more gas and dust, which can then be transformed into new stars. Apus is a constellation that borders the Octans constellation which is the most southernly constellation we have. https://www.britannica.com/topic/Apus-astronomy, The University of Wisconsin - Department of Astronomy - Apus, Apus - Student Encyclopedia (Ages 11 and up).
