Milenko Puzigaca Posted August 15, 2021 Share Posted August 15, 2021 (edited) Bleda plava tačka je fotografija planete Zemlje koju je 14. februara 1990. godine napravila svemirska sonda Vojadžer 1. Na fotografiji se planeta Zemlja pojavljuje kao sićušna mrlja, otprilike na pola smeđe trake udesno, nasuprot beskrajnom prostranstvu svemira. Fotografija je snimljena sa udaljenosti od oko 6 milijardi kilometara kao deo serije slika našeg Sunčevog sistema. Vojager 1 je završio svoju primarnu misiju i napuštao je Sunčev sistem. Na predlog astronoma i pisca Karla Sagana, NASA je komandovala sondi Vojadžer da okrene kameru, i napravi poslednju fotografiju Zemlje preko beskrajnog prostranstva svemira, pre nego što napusti sunčev sistem. Carl Sagan je komentarisao ovu fotografiju: „Pogledajte ponovo tu tačku. To je ovde. To je dom. To smo mi. Tu su svi koje volite, svi koje poznajete, svi za koje ste ikada čuli, svako ljudsko biće koje je ikada živelo. To je skup naše radosti i patnje, hiljada sveznajućih religija, ideologija i ekonomskih doktrina, to je svaki lovac i tragač, svaki heroj i kukavica, svaki graditelj i uništitelj. Svaki kralj i seljak, svaki zaljubljeni mladi par, svaka majka i otac, svaki pronalazač i istraživač, svaki učitelj morala, svaki korumpirani političar, svaka „super zvezda“, svaki „vrhovni vođa“, svaki svetac i grešnik u istoriji naše vrste živeli su tu - na tom zrnu prašine koje lebdi u zraku svetlosti. Zemlja je samo mala pozornica u ogromnoj kosmičkoj areni. Pomislite na beskrajne okrutnosti koje su stanovnici jednog dela ove tačke počinili nepoznatim stanovnicima nekog drugog dela, koliko su česti bili njihovi nesporazumi, koliko su željni da se međusobno ubijaju, koliko su žestoke njihove mržnje. Pomislite na reke krvi koje su prolili svi ti generali i carevi, kako bi, u slavi i trijumfu, mogli da postanu trenutni gospodari delića ove tačke. Sva naša uverenja, sva naša zamišljena važnost, sve naše zablude da imamo neki poseban položaj u Univerzumu, sve je to dovedeno u pitanje ovom tačkom blede svetlosti. Naša planeta je samo usamljena mrlja u velikom svemirskom mraku koji nas obavija. Uprkos svim našim zabludama, nema nagoveštaja da će pomoć doći od bilo koga drugog da nas spasi od nas samih. Zemlja je jedini do sada poznat svet na kome postoji život. Nema drugog mesta, bar ne u bliskoj budućnosti, na koje bi naša vrsta mogla da migrira. Da poseti, da. Da se naseli, još ne. Sviđalo nam se to ili ne, trenutno je Zemlja jedino mesto na kome postojimo. Kaže se da je bavljenje astronomijom iskustvo koje gradi karakter i dovodi do poniznosti. Možda nema bolje demonstracije besmislenosti ljudskih uobrazilja o sopstvenoj važnosti od ove fotografije našeg majušnog sveta. Za mene, ova fotografija predstavlja našu odgovornost da se ljubaznije odnosimo jedni prema drugima, kao i našu obavezu da čuvamo i cenimo ovu bledu plavu tačku, jedini dom za koji smo ikada znali. “ - Carl Sagan Edited August 15, 2021 by Milenko Puzigaca 6 2 1 Link to comment Share on other sites More sharing options...
Milenko Puzigaca Posted August 15, 2021 Share Posted August 15, 2021 I original Quote “Look again at that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every "superstar," every "supreme leader," every saint and sinner in the history of our species lived there-on a mote of dust suspended in a sunbeam. The Earth is a very small stage in a vast cosmic arena. Think of the endless cruelties visited by the inhabitants of one corner of this pixel on the scarcely distinguishable inhabitants of some other corner, how frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds. Think of the rivers of blood spilled by all those generals and emperors so that, in glory and triumph, they could become the momentary masters of a fraction of a dot. Our posturings, our imagined self-importance, the delusion that we have some privileged position in the Universe, are challenged by this point of pale light. Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity, in all this vastness, there is no hint that help will come from elsewhere to save us from ourselves. The Earth is the only world known so far to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Visit, yes. Settle, not yet. Like it or not, for the moment the Earth is where we make our stand. It has been said that astronomy is a humbling and character-building experience. There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly with one another, and to preserve and cherish the pale blue dot, the only home we've ever known.” ― Carl Sagan 4 Link to comment Share on other sites More sharing options...

Једноставно, Месец је много мањи. Објекат удаљен 80 километара на Земљи, да би био видљив, морао би бити огроман. Мислим да се ни Бурџ Калифа не би видела са те раздаљине. Из топографије, када се на нашој планети проверава оптичка видљивост два објекта, на даљинама од преко 5 километара, узима се у обзир и закривљеност планете. На Месецу, да би објекат био видљив са те даљине, морао би бити велик неколико километара. Komentar sam da ne poverujete preuzeo sa b92, međutim čovek je apsolutno u pravu.

McLeod Posted December 14, 2021 Share Posted December 14, 2021 James Webb Space Telescope izgleda konacno ide u orbitu, lansiranje je zakazano za 22. decembar. Nadam se da vise nema odlaganja i da ce sve raditi kako treba. Ide u lagranz tacku, treba mu mesec dana do tamo. Ovaj teleskop bi trebalo da bude gamechanger, nikada nismo imali nesto tako mocno i bice sposoban da detektuje atmosferu obliznjih egzoplaneta. 4 Link to comment Share on other sites More sharing options...

McLeod Posted December 28, 2021 Share Posted December 28, 2021 Video sam neko istrazivanje oko rogue planeta (planeta bez zvezde, koje plutaju same u tami) i ima ih bukvalno 20 puta vise nego sto je prvobitno procenjeno. Sto bi znacilo da oko Zemlje, u radijusu od Sunca do Proxima Centauri ima cak oko 70 takvih planeta. Sto moze imati interesantne implikacije i po mogucnost da takav objekat prodje kroz Suncev sistem. Znamo da je jedna zvezda prosla kroz Ortov oblak pre 100-ak miliona godina i prouzrokovala "bombardovanje" unutrasnjih planeta, ako ih ima 70 puta vise (ako taj broj nije preteran) nego zvezda, onda bi po teoriji verovatnoce na svakih 1.5 milion godina jedna planeta trebalo da prodje dovoljno blizu da gravitaciono utice na tela u Suncevom sistemu.
