Uranometría Argentina Bicentenario
URANOMETRÍA ARGENTINA BICENTENARIO Reedición electrónica ampliada, ilustrada y actualizada de la URANOMETRÍA ARGENTINA Brillantez y posición de las estrellas fijas, hasta la séptima magnitud, comprendidas dentro de cien grados del polo austral. Resultados del Observatorio Nacional Argentino, Volumen I. Publicados por el observatorio 1879. Con Atlas (1877) 1 Observatorio Nacional Argentino Dirección: Benjamin Apthorp Gould Observadores: John M. Thome - William M. Davis - Miles Rock - Clarence L. Hathaway Walter G. Davis - Frank Hagar Bigelow Mapas del Atlas dibujados por: Albert K. Mansfield Tomado de Paolantonio S. y Minniti E. (2001) Uranometría Argentina 2001, Historia del Observatorio Nacional Argentino. SECyT-OA Universidad Nacional de Córdoba, Córdoba. Santiago Paolantonio 2010 La importancia de la Uranometría1 Argentina descansa en las sólidas bases científicas sobre la cual fue realizada. Esta obra, cuidada en los más pequeños detalles, se debe sin dudas a la genialidad del entonces director del Observatorio Nacional Argentino, Dr. Benjamin A. Gould. Pero nada de esto se habría hecho realidad sin la gran habilidad, el esfuerzo y la dedicación brindada por los cuatro primeros ayudantes del Observatorio, John M. Thome, William M. Davis, Miles Rock y Clarence L. Hathaway, así como de Walter G. Davis y Frank Hagar Bigelow que se integraron más tarde a la institución. Entre éstos, J. M. Thome, merece un lugar destacado por la esmerada revisión, control de las posiciones y determinaciones de brillos, tal como el mismo Director lo reconoce en el prólogo de la publicación. Por otro lado, Albert K. Mansfield tuvo un papel clave en la difícil confección de los mapas del Atlas. La Uranometría Argentina sobresale entre los trabajos realizados hasta ese momento, por múltiples razones: Por la profundidad en magnitud, ya que llega por vez primera en este tipo de empresa a la séptima. -
June 2006 (In the Coils of the Water Snake)
Eridanus Optics CC June 2006 Constellation: Hydra (The Female Water Snake) Introduction Although Hydra is the largest constellation in the sky, it is not very prominent. The head forms the most prominent feature and is found on the western side of the constellation. The snake follows its ‘head’ through the sky, starting east of Monoceros, ending over 100º to the east at Centaurus 2 and Lupus. The constellation thus spans close to /3 of the visible sky from West to East. (See Map 1) In Greek mythology, Hydra was the multi-headed monster slain by Hercules as one of his twelve tasks. It is also linked in legends to Corvus (the Crow) and Crater (the Cup), two constellations found on the back of Hydra. Naked eye objects A few naked eye objects are visible. Only Alfard (The Solitary One) is brighter than Magnitude 3. The name is a reference to this star being the only bright object in the area. Alfard is about 20º South of Regulus (Leo). (At an arm’s length from your eye, if you spread your hand wide, the distance between the tip of your little finger and the end of your thumb can be taken as 20º.) From dark sky sites, the head can be seen as well as several other stars along the body of the snake. To locate the head, start at Alfard and find the trinity of stars to the North (right). Further down (West), you’ll find Theta Hydrae and Omega Hydrae, followed by the head. (See Map 2). I could see only two stars of the head from Pretoria without optical aid. -

This range of spectral types includes very low mass stars, brown dwarfs, and planetary mass objects, providing fundamental parameters across both the hydrogen and deuterium burning minimum masses for the largest sample assembled to date. A subsample of 29 objects have well constrained ages as probable members of a nearby young moving group (NYMG). -

Despite adverse conditions at times, we had some absolutely stunningly clear nights over the past couple of weeks so I hope everybody found some time to go out and do a little observing or imaging. With a little bit of luck, we can get a few more of these evenings after our quarantine is over so we can get in a little more scope time before the mosquitoes muster their numbers. Unfortunately, April saw the loss of two very promising comets, but we were introduced to a new Comet in Swan, which early indications suggest could be a pretty nice early evening comet. -

Black Holes, Chaos in Universe, Processes in Space, Stars, Galaxies, Ordered Universe
International Journal of Astronomy 2020, 9(1): 12-26 DOI: 10.5923/j.astronomy.20200901.03 Black Hole & There is no Chaos in the Universe Weitter Duckss Independent Researcher, Zadar, Croatia Abstract This year's Nobel's Prize in physics has turned into another degradation of science. The first part of the article (3.) deals with chaos that includes very different star systems. Inside a system there are objects with a lot of satellites and those with none. Some planets in distant orbits and brown dwarfs are warmer than some stars. The objects and stars of the same mass have completely different temperatures and are often classified into almost all star types. There is light inside an atmosphere or on the surface of an object without an atmosphere, but it disappears just outside the atmosphere or the surface of the object without the atmosphere. There are galaxies with the blueshift and redshift; although the Universe expands faster and faster, there are 200 000 galaxies and clusters of galaxies that merge or collide. There are enormous differences in the quantity of redshift at the same distances for galaxies and larger objects, i.e., there are different distances – with the differences measured in billions of light-years – for the same quantities of redshift. The other part of the article (4.) removes chaos and returns order in the Universe by implementing identical principles in the whole of the volume and for all objects. Keywords Black holes, Chaos in universe, Processes in space, Stars, Galaxies, Ordered universe universality and removing any paradox that might negate the 1.
