A rare galaxy that's challenging our understanding of the universe | Burçin Mutlu-Pakdil

Prevodilac: Katarina Čolić Lektor: Ivana Korom

There are more than a trillion galaxies in the universe.

Postoji više od bilion galaksija u univerzumu.

And my team discovered an extremely rare one,

A moj tim otkrio je jednu izuzetno retku

a galaxy that doesn't look quite like anything observed before.

koja ne liči ni na jednu galaksiju otkrivenu ranije.

This galaxy is so peculiar,

Ova galaksija je toliko neobična

that it challenges our theories and our assumptions

da dovodi u pitanje naše teorije i naše pretpostavke

about how the universe works.

o funkcionisanju univerzuma.

The majority of the galaxies are spiral,

Većina galaksija je spiralnog oblika,

similar to our own Milky Way.

slično našem Mlečnom putu.

We have strong theories about how these common galaxies form and evolve.

Postoje jake tvrdnje o formiranju i razvoju ovih uobičajenih galaksija.

But we don't understand how rare galaxies form and evolve.

Ali mi ne razumemo kako se formiraju i razvijaju retke galaksije.

An especially puzzling rare case is Hoag's Object.

Jedna takva retka galaksija koja nam zadaje muke je Hoagov objekat.

It has a very symmetric central body surrounded by a circular outer ring,

Ona ima vrlo simetrično telo u sredini okruženo kružnim spoljašnim prstenom,

with nothing visible connecting them.

a ništa vidljivo ih ne povezuje.

Hoag-type galaxies are among the rarest types of galaxies currently known.

Galaksije nalik Hoagovoj spadaju u najređe trenutno poznate galaksije.

There are fewer than one in 1,000 galaxies.

Postoji manje od jedne na 1000 galaksija.

It's a mystery how the stars in the outer ring are just floating there

Prava je misterija kako zvezde spoljašnjeg prstena samo lebde tu,

in such an orderly manner.

a na tako organizovan način.

That's interesting, right?

Interesantno, zar ne?

Hold on.

Samo malo.

Things are about to get more mysterious.

Postaće misterioznije.

The galaxy that my team discovered is even rarer

Galaksija koju je moj tim otkrio je ređa

and much more complex than that.

i mnogo složenija od toga.

You know, sometimes, you search and search for these objects,

Nekada ste u potrazi za tim objektima,

and you find nothing.

a ne pronađete ništa.

But sometimes, it just appears in the background,

Međutim, nekad se samo pojave u pozadini

when you are not even looking for it.

kada ih ne tražite.

This system looks very similar to Hoag's Object,

Ovaj sistem je veoma sličan Hoagovom objektu

with its central body and circular outer ring.

zbog tela u sredini i kružnog spoljašnjeg prstena.

We got very excited and thought we discovered another Hoag's Object.

Obradovali smo se pri pomisli da smo otkrili još jedan Hoagov objekat.

But my research showed this is an entirely new galaxy type,

Međutim, moje istraživanje je otkrilo da je to potpuno novi tip galaksije

now commonly referred to as "Burçin's Galaxy."

koji se sada naziva „Burčin galaksija”.

(Laughs)

(Smeh)

(Cheers) (Applause)

(Klicanje) (Aplauz)

We will not be visiting this galaxy anytime soon.

Nećemo posetiti ovu galaksiju u skorije vreme.

It is approximately 359 million light years away from Earth.

Udaljena je približno 359 miliona svetlosnih godina od Zemlje.

You may think this is far.

Mislite da je to daleko.

Well, actually, this is one of the nearby galaxies.

Zapravo, ovo je jedna od bližih galaksija.

I study this object in different light --

Proučavam ovaj objekat na drugačijoj svetlosti -

in ultraviolet, optical and near-infrared.

ultraljubičastoj, optičkoj i blisko infracrvenoj.

Small details on our body, like a scar or wrinkles,

Mali detalji na našem telu, poput ožiljka ili bora

tell the story of our lives.

pričaju našu životnu priču.

Similarly, a galaxy's structure in different light

Slično tome, struktura jedne galaksije na drugačijoj svetlosti

can help us trace back their origin and evolution.

nam može pomoći da odredimo njeno poreklo i razvoj.

How do I look for these details?

Kako tražim te detalje?

I model the bright central body

Modeliram sjajno središnje telo

and remove my model from the image

i uklonim model sa slike

to check for any hidden features,

kako bih potražila skrivene karakteristike

because a bright structure in a galaxy may blind our views of faint features,

jer sjajna struktura u galaksiji može da zakloni neupadljive karakteristike,

just like using sunglasses when you are blinded by the intense light.

poput korišćenja naočara za sunce kada vas zaslepi sunčeva svetlost.

The result was a big surprise.

Došli smo do iznenađujućeg rezultata.

This galaxy doesn't just have an outer ring,

Ova galaksija pored spoljašnjeg prstena

it has an additional, diffused inner ring.

ima još jedan, difuzan, unutrašnji prsten.

We were having a hard time explaining the origin of the outer ring

Nije bilo lako da objasnimo poreklo spoljašnjeg prstena

in Hoag-type galaxies.

u galaksiji Hoagovog tipa.

Now we also need to explain this mysterious second ring.

Sada moramo da objasnimo taj misteriozni drugi prsten.

There is currently no known mechanism

Trenutno nije poznat mehanizam koji može da objasni

that can explain the existence of an inner ring in such a peculiar galaxy.

postojanje unutrašnjeg prstena u tako neobičnoj galaksiji.

So the discovery of Burçin's Galaxy clearly highlights the gap

Stoga otkriće Burčin galaksije jasno ističe nedostatak

in our knowledge of galaxy evolution.

u našem znanju o razvoju galaksija.

Further research into how this extremely rare galaxy was formed

Dalje istraživanje o tome kako se ova vrlo retka galaksija formirala

can provide us with new clues on how the universe works.

daće nam nove uvide u to kako univerzum funkcioniše.

This discovery tells us that we still have a lot to learn,

Ovo otkriće nam govori da imamo još da učimo

and we should keep looking deeper and deeper in space

i da treba da se zagledamo što dublje u svemir

and keep searching for the unknown.

i nastavimo sa potragom za nepoznatim.

Thank you.

Hvala vam.
