Kurs je besplatan, osim za one koji žele sertifikat (što je ukupno 4x50 USD - inkorporira 4 kursa, sve zajedno 180USD.) Prezentatori su astrofizičari profesori Brian Schmidt i Paul Francis. Svi kursevi zajedno su ekvivalent prve godine studija astrofizike na ANU. Hide contents ANU Astrophysics Course: Syllabus The Four Courses We are offering four courses (ANU-ASTRO1x, ANU-ASTRO2x, ANU-ASTRO3x, ANU-ASTRO4x) which together make up the ANU’s first year astrophysics course. These courses can be taken in any order. ANU- ASTRO1x introduces some topics used in the other courses, so if you don’t do it first, you may need to do a little background reading. Here is the combined syllabus for these four courses. ANU-ASTRO1x Greatest Unsolved Mysteries of the Universe Section 1: The Expanding Universe Section 2: The Big Bang Section 3: Dark Energy Section 4: Giant Black Holes Section 5: First Light in the Universe Section 6: Gamma-Ray Bursts Section 7: Dark Matter Section 8: Solar System Formation Section 9: Life in Space ANU-ASTRO2x Exoplanets Section 1: Pulsar planets Section 2: Finding Planets using Reflex Motion Section 3: More radial velocity planets and transits Section 4: Recent transit results Section 5: Gravitational Microlensing Section 6: Debris Disks Section 7: Adaptive Optics Section 8: Direct Imaging Section 9: Earth-like planets ANU-ASTRO3x The Violent Universe Section 1: White dwarf stars Section 2: Degenerate stars and Quantum Mechanics Section 3: Dwarf Novae Section 4: Classical Novae, the Chandrasekhar Limit and Nuclear Physics Section 5: Thermonuclear Supernovae Section 6: Core Collapse Supernovae Section 7: X-ray astronomy and Neutron stars Section 8: Special Relativity Section 9: Black Holes ANU-ASTRO4x Cosmology Section 1: Space and Time Section 2: Dynamics and geometry of our universe Section 3: Inflation Section 4: Observational Cosmology Section 5: New observational techniques Section 6: Dark Energy Section 7: Acoustic Peaks Section 8: Entropy Section 9: The Origin and fate of the universe Bonus Section: The Future of Astrophysics Zanimljivo. Ima tome pa skoro 2 decenije, kada sam se preselio iz vesele Svrbije u Junatjed Setjts i ja tada jos uvek bejase hat da svoja astronomiseckaja saznanja podelim sa vascelim svjatom, koji samo sto nije to cekao, jelte. Tako sam, u nekom momentu, bice, naleteo, mozebiti bas na ovaj avstralijski onlajn juniverziti (zipa, pricamo o stvarima koje se dogadjaju nekima i lajftajm ejgou, smrc:)) sa uglavnom, i nazalost, astrofizickim kursevima. Mi, biing an astronomer, a ne tamo neki astrofizicar, bejah dvostruko obeshrabren, zbog nepodobnih kurseva koji su nudjeni, a koje bi cak mozda i uspeo da usaglasim sa svojim interesovanjima nekako da se nisu isprecile neumitne finansijske prepreke u vrednostima teske desetina tisuca AUD. Ondah se presaltah na NYC visu skolu za racunare, mnogo bese jeftinije... Bar sam tako naivno mislio. Iako se danas bavim sasvim devetim poslovima... A ne racunarima i zvezdocatstvom. Maj tu sents: Predavanja o egzoplanetma su zanimljiva u neku ruku (mada je polovina navedenih stvari iz teorijske astronomije), jer u moje vreme ona nisu ni postojala, ostala predavanja spadaju u Opstu Astrofiziku, druga godina Matematickog fakulteta, tj. pickin dim.

September 25, 20231 yr Bennu je stigao! Like a dream’: successful return of Nasa capsule with asteroid sample hailed
September 29, 20231 yr Yesterday, after 10 years of research, the International Astronomical Union have named the asteroid 2013 TF19, "Fraser", after Elizabeth Fraser. Discovered 2013-08-31 by M. Kusiak, M. Żołnowski at Tincana, it does not pose a threat to humankind and will not collide with Earth for millions of years. It can only be viewed using an advance telescope but luckily is available to see on NASA - National Aeronautics and Space Administration's website. https://ssd.jpl.nasa.gov/tools/sbdb_lookup.html#/?sstr=fraser&view=OPD Slicka tela: https://www.facebook.com/photo.php?fbid=10231963202289759&set=p.10231963202289759&type=3 Edited September 29, 20231 yr by I*m with the pilots

November 6, 20231 yr uf, to mi nikako ne bi trebali da vidimo, to ukazuje na prodor radijacije sa sunca kroz magnetno polje zemlje, da li se desila neka solarna oluja? - ostajemo li danas bez elektronike? - da li je naglo oslabilo magnetno polje u najavi izmene orjentacije istog - ili je neka zvezda u blizini postala supernova pa nas je malo oprljila gama radijacija od tog događaja
November 6, 20231 yr Baš htedoh da pitam da li je neko video? Ovi moji NSađani će večeras u osmatranje, pretpostavljam na Frušku goru.
