We believe that BCD gezegde

 We believe that BCD galaxies are similar to the universe's first galaxies because they are infant galaxies, actively forming stars, and are not very chemically polluted.

 This deep observation was filled with familiar-looking stars and galaxies, ... We removed everything we knew---all the stars and galaxies both near and far. We were left with a picture of part of the sky with no stars or galaxies, but it still had this infrared glow with giant blobs that we think could be the glow from the very first stars.

 In fact these small galaxies are attracted by large galaxies during their gravitational pull, and they merge together to make a big center of galaxies. Some of them do not become pray to the gravitational pull of bigger galaxies due to vast distance of space, hence such petrified remains or fossils of small galaxies stay aloof but they survive and this finding may lead them to this conclusion.

 It shows that these galaxies are not in equilibrium, that something is pulling stars out of these galaxies. On this scale the only thing we know of that can do this is another galaxy, and we can actually see that.

 There should have been a period when most of the atoms in the universe were neutral. This would have continued until stars and galaxies began forming.

 We removed everything we knew---all the stars and galaxies both near and far. We were left with a picture of part of the sky with no stars or galaxies, but it still had this negative glow with giant blobs that we think could be the glow from the very first stars.

 We have now been able to track star formation in galaxies out to modest distances, more than half the age of the universe, and we find that all galaxies, big or small, seem to be fading gradually so that they are less active today than they were further back in time.

 When astronomers look billions of light years into space, all they can see are the bright, high-mass stars in very distant galaxies. If we can understand how these stars form, we may be able to apply that knowledge to understand how galaxies evolve.

 We know that these galaxies are involved in vast mergers and collisions. It's possible that some of the emission we see from them is created not by stars, but by vast shocks in the gas between colliding galaxies.

 The dynamics within the core of this neighboring galaxy may be more common than we think. Our own Milky Way apparently has even younger stars close to its own black hole. It seems unlikely that only the closest two big galaxies should have this odd activity. So this behavior may not be the exception but the rule. And we have found other galaxies that have a double nucleus.

 The great minds gathered here today ... have the possibility to peer into ordinarily unimaginable vistas of time and space, to discover what the universe was like, when the first stars and galaxies were forming,

 Our findings suggest that unseen dark matter - which emits no light but has mass - has had a major effect on the formation and evolution of galaxies, and that bright active galaxies are only born within dark matter clumps of a certain size in the young universe.

 We predict that other velocity tracers in the same elliptical galaxies will show higher velocities if they are less concentrated toward the galaxy center or if they move on more circular orbits. This is likely to be the case for compact star clusters, which are also observable in the outskirts of elliptical galaxies.
