Više od 200 astronoma iz 18 zemalja stvorilo je novu kartu svemira; ima 300 tisuća novih galaksija

Koristili su teleskop koji može detektirati izvore svjetlosti koje optički instrumenti ne mogu vidjeti

Nešto ubija galaksije i znanstvenici već neko vrijeme pokušavaju otkriti što. Izgleda da nova studija ima odgovor

Galaksije prerano umiru zbog pritiska pri kretanju tijela te gubitka plina

In this ESA/Hubble & NASA handout released October 12, 2015 NGC 4639 is shown, a beautiful example of a type of galaxy known as a barred spiral. It lies over 70 million light-years away in the constellation of Virgo and is one of about 1500 galaxies that make up the Virgo Cluster. In this image, taken by the NASA/ESA Hubble Space Telescope, one can clearly see the bar running through the bright, round core of the galaxy. Bars are found in around two thirds of spiral galaxies, and are thought to be a natural phase in their evolution. The galaxys spiral arms are sprinkled with bright regions of active star formation. Each of these tiny jewels is actually several hundred light-years across and contains hundreds or thousands of newly formed stars. But NGC 4639 also conceals a dark secret in its core a massive black hole that is consuming the surrounding gas. This is known as an active galactic nucleus (AGN), and is revealed by characteristic features in the spectrum of light from the galaxy and by X-rays produced close to the black hole as the hot gas plunges towards it. Most galaxies are thought to contain a black hole at the centre.

Izgleda da u svemiru postoji oko 2000 milijardi galaksija, što je 10 puta više nego što smo dosad mislili

Nova studija je analizirala podatke Hubblea i drugih teleskopa

Amerikanci prave najjaču kameru u povijesti koja će snimati galaksije u rezoluciji od 3,2 gigapiksela

To je 1500 puta veća rezolucija od HD TV-a i 400 puta veća od iPhonea6
