J-♣ Posted April 21, 2023 Posted April 21, 2023 Srećna okolnost u neuspehu da niko nije poginuo. Ne ponovilo im se Challenger i Columbia.

Šta se to priča da je prejaka za launch pad, da je bukvalno napravila gomilu šrapnela od betona i da postoji mogućnost da je to oštetilo raketu zapravo. Shoddy workmanship?
Arkadija Posted April 21, 2023 Posted April 21, 2023 Nemam pojma, nisam to videla. Mene su juče najviše zabavili komentari vaskolikog srBstva na tu vest. Toliko zluradosti, neznanja i rusofilije davno nisam videla.
burekdzija Posted April 21, 2023 Posted April 21, 2023 Steta, ali i to je deo procesa. A zasto se srpstvo ovome raduje, ne mogu ni da naslutim. Sto je dobro.

Named the Nigaloo Eclipse, the total eclipse portion of the event passed over North West Cape on the very remote western edge of Western Australia.

Indy Posted April 28, 2023 Posted April 28, 2023 (edited) Wow - isti moment snimljen sa pokojne japanske sonde "Hakuto-r" - ovo je bukvalno poslednji snimak koji je od nje stigao! RIP mala probo, domo arigato gozaimasu EDIT. Ispravka - nije isti moment, u trenutku ove fotke pomračenje je još uvek bilo negde iznad Indonezije. (Fotka je rel. visoke rezolucije, ako se zumira može da se vidi bolje gde je tačno pomračenje. Btw. Hakuto-R nije krešovao, verujem, već se odmetnuo kao Major Tom Edited April 28, 2023 by Indy 2 2

NiZdr Posted August 12, 2023 Posted August 12, 2023 Ако нисте планирали ништа битно вечерас, послушајте савет са ПМФ-а и лезите на леђа. Quote Sa Prirodno-matematičkog fakulteta u Kragujevcu objašnjavaju da se kiša meteora periodično javlja tokom godine, a da je u avgustu najveći intezitet, jer Zemlja tada prolazi kroz najveći roj meteorida. Perseide su treća najintezivnija meteorska kiša, a vrhunac aktivnosti ćemo posmatrati u noći između 12. i 13. avgusta. Najbolje vreme za posmatranje biće kada Mesec nestane sa neba, oko zore. Preporučljivo je da se smestite na čistinu u prirodi, i da legnete na leđa kako biste povećali vidljivost i mogli da vidite ceo nebeski svod, kažu sa PMF-a. https://www.glassumadije.rs/kisa-meteora-u-noci-izmedju-12-i-13-avgusta/
Њујоркер Posted August 12, 2023 Posted August 12, 2023 (edited) Quote Najbolje vreme za posmatranje biće kada Mesec nestane sa neba, oko zore. Jok, najbolje u podne. Kad nepismeni novinari ne umeju ni da prenesu ono sto im se govori. Perseide posmatrati tokom cele noci, od 10-11 navece pa do zore, nece biti Meseca da smeta ni 12 ni 13 kada je pik, i kada mozemo ocekivati i do 100 meteora na cas, ako bude srece. Mesec ce se pojaviti tek u zoru, u fazi tankog srpa, u sazvezdju Blizanaca, oko zvezda Poluks i Kastor. uzgred, naravno da ce se leci na ledja, nece valjda na stomak.

Indy Posted August 17, 2023 Posted August 17, 2023 Ne mogu da nađem bolje mestou, pa ću ostaviti ovde (a i šansa je da ovde zalaze oni koje to zanima): https://www.edx.org/xseries/astrophysics EdX onlajn kurs astrofizike sa Australian National University (ANUx ANU-ASTRO1x). 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. Spoiler 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 7
