Srećna okolnost u neuspehu da niko nije poginuo.

Ne ponovilo im se Challenger i Columbia.

Nemam pojma, nisam to videla. Mene su juče najviše zabavili komentari vaskolikog srBstva na tu vest. Toliko zluradosti, neznanja i rusofilije davno nisam videla.

Steta, ali i to je deo procesa.

 

A zasto se srpstvo ovome raduje, ne mogu ni da naslutim. Sto je dobro.

setiinstitute #PPOD: Australian Eclipse

On April 20, 2023, a hybrid solar eclipse occurred. 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. NASA's Deep Space Climate Observatory (DSCOVR) captured this image of the Moon's shadow during that time.

Wow - isti moment snimljen sa pokojne japanske sonde "Hakuto-r" - ovo je bukvalno poslednji snimak koji je od nje stigao! :cry: 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

Ако нисте планирали ништа битно вечерас, послушајте савет са ПМФ-а и лезите на леђа. :D

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.

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.

Ne mogu da nađem bolje mestou, pa ću ostaviti ovde (a i šansa je da ovde zalaze oni koje to zanima):

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.
