No início, a observação do movimento Hemerson Brandão [email protected] gradual dos corpos celestes ajudou aos primórdios da civilização na contagem e regularização do tempo, e por esse motivo, a Astronomia é considerada uma das Diagramadores Rodolfo Saccani ciências mais antigas da humanidade. [email protected] Foi na Antiga Grécia, por volta de 450 a.C., que os Sharon Camargo gregos começaram a fazer os primeiros registros [email protected] detalhados do movimento dos astros, tentando entender Hemerson Brandão [email protected] as suas causas. Ricas histórias mitológicas explicavam o porque de cada constelação no céu, enquanto filósofos debatiam uma explicação para o movimento Redatores Audemário Prazeres dos astros errantes, os planetas. [email protected] Atualmente parte desse conhecimento foi Hélio “Gandhi” Ferrari sobrepujado por anos de conhecimentos científicos [email protected] adquiridos ao longo da história, mas muitos resquícios Laércio F.

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. -

Back Cover ON THE COVER: Figure from Roger Venable’s four station occultation event. Here’s Roger’s description: When 2 Pallas at magnitude 9.6 occulted a Tycho catalog star at mag 11.7 on the night of June 11-12, I was waiting with four stations. I set up one in my backyard in Augusta, GA, one an hour down the road, and one an hour past that. I had planned to drive an hour further south for the fourth station, but as I drove south I ran into the cloud bands of hurricane Alberto, so I hastily returned northward and set up the fourth station between my second and third ones, just in time for the event. As luck would have it, there were no clouds at the north and south stations, and the other two had intermittent cirrocumulus. All four stations recorded a hit. This is the first time an observer has gotten four hits on a single event. -

It is concerned with the evolution, physics, chemistry, meteorology, and motion of celestial objects, as well as the formation and development of the universe. Astronomy is one of the oldest sciences. Prehistoric cultures left behind astronomical artifacts such as the Egyptian monuments and Stonehenge, and early civilizations such as the Babylonians, Greeks, Chinese, Indians, and Maya performed methodical observations of the night sky. However, the invention of the telescope was required before astronomy was able to develop into a modern science. Historically, astronomy A giant Hubble mosaic of the Crab Nebula, a supernova remnant has included disciplines as diverse as astrometry, celestial navigation, observational astronomy, the making of calendars, and even astrology, but professional astronomy is nowadays often considered to be synonymous with astrophysics. -
