In Muslim astronomy, the first star chart to be drawn accurately was most likely the illustrations produced by the Persian astronomer Abd al-Rahman al-Sufi in his 964 work titled Book of Fixed Stars. This book was an update of parts VII.5 and VIII.1 of the 2nd century Almagest star catalogue by Ptolemy .
SN 2016aps (also known as PS16aqy and AT2016aps) is the brightest and most energetic supernova explosion ever recorded. [2] [3] It released more energy than ASASSN-15lh. [4]In addition to the sheer amount of energy released, an unusually large amount of the energy was released in the form of radiation, probably due to the interaction of the supernova ejecta and a previously lost gas shell.
Celestial cartography, [1] uranography, [2] [3] astrography or star cartography [citation needed] is the aspect of astronomy and branch of cartography concerned with mapping stars, galaxies, and other astronomical objects on the celestial sphere. Measuring the position and light of charted objects requires a variety of instruments and techniques.
Sky-Map.org (or WikiSky.org) is a wiki and interactive sky map that covers over half a billion known celestial bodies. [1] WikiSky is designed, in part, as a wiki.Users can edit information about different stars by writing articles, adding Internet links, uploading images, or creating a special interest group for a specific task.

The 2016 Nobel Prize in Chemistry is awarded to Jean-Pierre Sauvage, Sir J. Fraser Stoddart and Bernard L. Feringa for the design and synthesis of molecular machines. [ 287 ] [ 288 ] Scientists identify the maximum human lifespan at an average age of 115, with an absolute upper limit of 125 years old .
In astronomy, coordinate systems are used for specifying positions of celestial objects (satellites, planets, stars, galaxies, etc.) relative to a given reference frame, based on physical reference points available to a situated observer (e.g. the true horizon and north to an observer on Earth's surface).

The system lies approximately 79 light years from the Sun. HD 87884 is separated from Regulus by 176 ″ and is itself a close pair. Regulus, along with five slightly dimmer stars ( Zeta Leonis , Mu Leonis , Gamma Leonis , Epsilon Leonis , and Eta Leonis ) have collectively been called 'the Sickle', which is an asterism that marks the head of Leo.
