  • CONSTELLATION DELPHINUS, the DOLPHIN Delphinus Is a Constellation in the Northern Sky, Close to the Celestial Equator
    CONSTELLATION DELPHINUS, THE DOLPHIN Delphinus is a constellation in the northern sky, close to the celestial equator. Its name is Latin for dolphin. Delphinus was one of the 48 constellations listed by the 2nd century astronomer Ptolemy, and it remains among the 88 modern constellations recognized by the International Astronomical Union. It is one of the smaller constellations, ranked 69th in size. Delphinus' brightest stars form a distinctive asterism that can easily be recognized. It is bordered (clockwise from north) by Vulpecula the fox, Sagitta the arrow, Aquila the eagle, Aquarius the water-carrier, Equuleus the foal and Pegasus the flying horse. Delphinus does not have any bright stars; its brightest star is of magnitude 3.8. The main asterism in Delphinus is sometimes called Job's Coffin, formed from the four brightest stars: Alpha, Beta, Gamma, and Delta Delphini. Alpha and Beta Delphini are named Sualocin and Rotanev, respectively. When read backwards, they read as Nicolaus Venator, the Latinized name of Palermo Observatory's former director, Niccolò Cacciatore. THE STARS • Alpha Delphini, called Sualocin, is a blue-white hued main sequence star of magnitude 3.8, 241 light-years from Earth. • Beta Delphini, the brightest star in Delphinus is called Rotanev. It is a close binary star and, as noted by the American astronomer S. W. Burnham in 1873, divisible in only large amateur telescopes. To the unaided eye, it appears to be a white star of magnitude 3.6. It has a period of 27 years and is 97 light-years from Earth. • Gamma Delphini is a celebrated binary star among amateur astronomers.

  • Astronomie Pentru Şcolari
    NICU GOGA CARTE DE ASTRONOMIE Editura REVERS CRAIOVA, 2010 Referent ştiinţific: Prof. univ.dr. Radu Constantinescu Editura Revers ISBN: 978-606-92381-6-5 2 În contextul actual al restructurării învăţământului obligatoriu, precum şi al unei manifeste lipse de interes din partea tinerei generaţii pentru studiul disciplinelor din aria curiculară Ştiinţe, se impune o intensificare a activităţilor de promovare a diferitelor discipline ştiinţifice. Dintre aceste discipline Astronomia ocupă un rol prioritar, având în vedere că ea intermediază tinerilor posibilitatea de a învăţa despre lumea în care trăiesc, de a afla tainele şi legile care guvernează Universul. În plus, anul 2009 a căpătat o co-notaţie specială prin declararea lui de către UNESCO drept „Anul Internaţional al Astronomiei”. În acest context, domnul profesor Nicu Goga ne propune acum o a doua carte cu tematică de Astronomie. După apariţia lucrării Geneza, evoluţia şi sfârşitul Universului, un volum care s+a bucurat de un real succes, apariţia lucrării „Carte de Astronomie” reprezintă un adevărat eveniment editorial, cu atât mai mult cu cât ea constitue în acelaşi timp un material monografic şi un material cu caracter didactic. Cartea este structurată în 13 capitole, trecând în revistă problematica generală a Astronomiei cu puţine elemente de Cosmologie. Cartea îşi propune şi reuşeşte pe deplin să ofere răspunsuri la câteva întrebări fundamentale şi tulburătoare legate de existenţa fiinţei umane şi a dimensiunii cosmice a acestei existenţe, incită la dialog şi la dorinţa de cunoaştere. Consider că, în ansamblul său, cartea poate contribui la îmbunătăţirea educaţiei ştiinţifice a tinerilor elevi şi este deosebit de utilă pentru toţi „actorii” implicaţi în procesul de predare-învăţare: elevi, părinţi, profesori.

  • The COLOUR of CREATION Observing and Astrophotography Targets “At a Glance” Guide
    The COLOUR of CREATION observing and astrophotography targets “at a glance” guide. (Naked eye, binoculars, small and “monster” scopes) Dear fellow amateur astronomer. Please note - this is a work in progress – compiled from several sources - and undoubtedly WILL contain inaccuracies. It would therefor be HIGHLY appreciated if readers would be so kind as to forward ANY corrections and/ or additions (as the document is still obviously incomplete) to: [email protected]. The document will be updated/ revised/ expanded* on a regular basis, replacing the existing document on the ASSA Pretoria website, as well as on the website: coloursofcreation.co.za . This is by no means intended to be a complete nor an exhaustive listing, but rather an “at a glance guide” (2nd column), that will hopefully assist in choosing or eliminating certain objects in a specific constellation for further research, to determine suitability for observation or astrophotography. There is NO copy right - download at will. Warm regards. JohanM. *Edition 1: June 2016 (“Pre-Karoo Star Party version”). “To me, one of the wonders and lures of astronomy is observing a galaxy… realizing you are detecting ancient photons, emitted by billions of stars, reduced to a magnitude below naked eye detection…lying at a distance beyond comprehension...” ASSA 100.

  • On the Antiquity of the Star Coordinates from Indian Jyotiña Çästras
    On the Antiquity of the Star Coordinates from Indian Jyotiña Çästras Richard L. Thompson Bhaktivedanta Institute, P.O. Box 52 Badger, CA 93603 I INTRODUCTION A comparison is made between coordinates for 35 stars listed in traditional Indian astronomical texts ( jyotiña çästras) and the coordinates of corresponding stars listed in modern tables. I find that the error vectors pointing from the modern star positions to the corresponding jyotiña star positions are strongly correlated with the reversed proper motion vectors of the stars. Once precession is taken into account, the modern star positions show a tendency to move towards the jyotiña star positions as we go back in time. To evaluate this, I first consider the null hypothesis, which says that we should not expect to find a significant relationship between errors in jyotiña star coordinates and proper motions of stars. I give statistical arguments showing that this hypothesis is not correct. If there is a significant relationship between proper motions and jyotiña star coordinates, then the simplest explanation for this is that the jyotiña star coordinates were measured in the distant past. As time passed, the stars slowly moved from their positions and thereby generated error vectors pointing back along their paths. Given this hypothesis, it is possible to calculate the time of measurement of the jyotiña star coordinates. I find that these coordinates divide into a group 25,000–55,000 years old and a group less than 5,000 years old. There is also a group that cannot be clearly dated, and there is evidence suggesting that the stars in this group may not be correctly identified.

  • SJAA Ephemeris 2014
    The Ephemeris October 2014 Volume 25 Number 10 - The Official Publication of the San Jose Astronomical Association A Significant Solar Flare on Sept 10, 2014 A solar flare is an intense burst of radiation coming from the release of magnetic energy asso- ciated with sunspots. Flares are our solar system’s largest explosive events. They are seen as bright areas on the sun and they can last from minutes to hours. We typically see a solar flare by the photons (or light) it releases, at most every wavelength of the spectrum. The primary ways we monitor flares are in x-rays and optical light. Flares are also sites where particles (electrons, protons, and heavier particles) are accelerated. October 2014 Events The sun emitted a significant solar flare, peaking at 1:48 p.m. EDT on Sept. 10, 2014. NASA's Solar Dynamics Observatory captured images of the event. Harmful radiation from a flare can- Friday, Oct 03 not pass through Earth's atmosphere to physically affect humans on the ground. However -- In-Town Star party (Houge): 7:45 - 9:45pm when intense enough -- they can disturb the atmosphere in the layer where GPS and commu- nications signals travel. Sunday, Oct 05 Solar observing: 2-4PM This flare is classified as an X1.6 class flare. "X-class" denotes the most intense flares, while Fix-It Day: 2-4PM the number provides more information about its strength. An X2 is twice as intense as an X1, an X3 is three times as intense, etc. Saturday, Oct 11 Board Meeting: 6 -7:30pm General Mtg: 7:30-10pm Friday, Oct 17 Binocular Stargazing (RCDO) Friday, Oct 17 Beginner Astronomy Class: 7-8pm In-Town Star party (Houge): 7-9pm Saturday, Oct 18 Starry Nights Star Party: 7:30-9:30pm Ranch Cañada del Oro (RCDO) Saturday, Oct 25 Henry Coe - Dark-Sky Weekend Sunday, Nov 02 Solar observing: 2-4PM Fix-It Day: 2-4PM Saturday, Nov 08 Board Meeting: 6 -7:30pm General Mtg: 7:30-10pm SJAA events are subject to cancellation due to weather.

V A N D E N B O S Any opinions expressed in this memoir are those of the author(s) and do not necessarily reflect the views of the National Academy of Sciences. Biographical Memoir COPYRIGHT 1958 NATIONAL ACADEMY OF SCIENCES WASHINGTON D.C. ROBERT GRANT AITKEN December 31, 1864—October 29, 795/ BY WILLEM H. VAN DEN BOS OBERT GRANT AITKEN was born on December 31, 1864, in Jackson, R.California, and died on October 29,1951, in Berkeley, California. His father, Robert Aitken, came to America from Scotland and his mother, Wilhelmina Depinau, was the daughter of German im- migrants. His early education followed classical rather than scientific lines, as his mother wished him to enter the ministry. In 1880 he entered the Oakland High School and in 1883 Williams College, still with the ministry in view. However, he also took courses in biology and astronomy and did some work in the observatory under Truman Safrord. He graduated in 1887, but as a result of his reading he felt —though he remained a deeply religious man to the end of his days —that he could not become a preacher of the orthodox, doctrinaire theology of the day. He accepted a position as house master in the Hopkins Academy, Oakland. In 1888 Aitken married his high school classmate, Jessie L. Thomas, and accepted a position as head teacher in Livermore Col- lege, where he stayed until 1891, when he was appointed professor of mathematics in the (then) University of the Pacific.
