Svemir i sve vezano za svemir

Dokle god ne budu imali bliski susret treće vrste sa nekim macro asteroidom "mališe" će da piče. Oprema i nema nekog drugog razloga da se kvari, daleko su da bi temperatura varirala.

Samo što imam osećaj da će jednog dana da doguraju do par svetlosnih godina a neki napaljeni tinejdžer će da ih slupa u svoj ludoj vožnji negde tamo 3245. god.
 
Zanimljiv video o tehnikama koje se koriste za mjerenje razdaljina u univerzumu, od obima zemlje pa do najudaljenijih galaksija.

 
Snimak sa Marsa, poslao rover...

 
Ja se samo nadam da će neko nas da nađe jer ovako čisto sumnjam da ću da doživim let u svemir...
 
Fascinantno je da u toliko praznom prostoru tako mali mikro objekat kao Web (u odnoau na okruzenje) dobija vec 5 udarac od lansiranja.
Uvek mi se cinilo neverovatnim ali izgleda da gore imamo pravi vatromet meteroida...
 
Gravitacija Sunčevog sistema čini svoje.
Plus što sad imamo već dosta kosmičkog đubreta oko Zemlje.
 
Webb: Engineered to Endure Micrometeoroid Impacts

To protect Webb in orbit, flight teams can use protective maneuvers that intentionally turn the optics away from known meteor showers before they are set to occur. This most recent hit was not a result of a meteor shower and is currently considered an unavoidable chance event. As a result of this impact, a specialized team of engineers has been formed to look at ways to mitigate the effects of further micrometeoroid hits of this scale.

U utorak dobijamo prve slike sa JWST :love:



  • Carina Nebula. The Carina Nebula is one of the largest and brightest nebulae in the sky, located approximately 7,600 light-years away in the southern constellation Carina. Nebulae are stellar nurseries where stars form. The Carina Nebula is home to many massive stars, several times larger than the Sun.
  • WASP-96 b (spectrum). WASP-96 b is a giant planet outside our solar system, composed mainly of gas. The planet, located nearly 1,150 light-years from Earth, orbits its star every 3.4 days. It has about half the mass of Jupiter, and its discovery was announced in 2014.
  • Southern Ring Nebula. The Southern Ring, or “Eight-Burst” nebula, is a planetary nebula – an expanding cloud of gas, surrounding a dying star. It is nearly half a light-year in diameter and is located approximately 2,000 light years away from Earth.
  • Stephan’s Quintet: About 290 million light-years away, Stephan’s Quintet is located in the constellation Pegasus. It is notable for being the first compact galaxy group ever discovered in 1877. Four of the five galaxies within the quintet are locked in a cosmic dance of repeated close encounters.
  • SMACS 0723: Massive foreground galaxy clusters magnify and distort the light of objects behind them, permitting a deep field view into both the extremely distant and intrinsically faint galaxy populations.

NASA Shares List of Cosmic Targets for Webb Telescope’s 1st Images

NASA’s James Webb Space Telescope will soon reveal unprecedented and detailed views of the universe, with the release of its first full-color images and spectroscopic data. The targets, selected by an international committee, will be released July 12: Carina Nebula, WASP-96 b (spectrum)...

Prvi zvanični snimak sa JWST...
  • President Joe Biden unveiled this image of galaxy cluster SMACS 0723, known as Webb’s First Deep Field, during a White House event Monday, July 11
  • Webb’s image covers a patch of sky approximately the size of a grain of sand held at arm’s length by someone on the ground – and reveals thousands of galaxies in a tiny sliver of vast universe
  • Webb’s sharp near-infrared view brought out faint structures in extremely distant galaxies, offering the most detailed view of the early universe to date
  • NASA and its partners will release the full series of Webb’s first full-color images and data, known as spectra, Tuesday, July 12, during a live NASA TV broadcast

Човече, гледам фотографију већ 10 минута и импресиониран сам! Колико смо ми небитни у космосу...
 
Odakle uopste ideja da smo bitni? :)
 
Koliko veliki deo neba obuhvata slika. 😁

If you held a grain of sand up to the sky at arm’s length, that tiny speck is the size of Webb’s view in this image. Imagine — galaxies galore within a grain, including light from galaxies that traveled billions of years to us!

E sad i ti.... Da nismo u temi o astronomiji pa hajde, no svako ko je malo zagrebao po istoj odavno mu jasno gde smo i sta smo.
Ne svidja mi se sto mesaju politiku, njoj nije mesto u nauci u idealnom svetu...
 
Au bre, pa ova slika obuhvata nekoliko puta manje parčence neba nego čuvena Hubble Ultra Deep Field?!? o_O

Takođe, JWST je ovo snimao ekspozicjom od "samo" 12-ak sati.
Hubblov UDP sniman malo više od 11 dana.

Što se naše nebitnosti tiče, mene još više gađa Pale Blue Dot.

U svakoj ovoj svetloj tackici imas vrv stotine milijardi zvezda, oko kojih vecinom kruze planete :)
A ovo je jedna tackica svemira samo.. da, totalno smo nebitni ;)

Tolliko prostora....a ovde se ljudi ubijaju zbog parking mesta.
 
@KLNG to je zato što je većina lenja i inertna masa, koja bi parking pred uzlaznim vratima.
Niko ne želi da parkira negde kod Marsa pa da pešači do kuće. 😁
 
Ova žena je lepo analizirala sliku. Gravitational lensing je baš primetan na sredini fotografije.

 
Koga zanima da analizira, evo u većoj rezoluciji... ;)
