We have now been gezegde

 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.

 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.

 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 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.

 We are finding that mergers do not appear to play the dominant role in star formation, because we see normal-looking, undisturbed galaxies that are undergoing large amounts of star formation.

 Who are we? We find that we live on an insignificant planet of a humdrum star lost in a galaxy tucked away in some forgotten corner of a universe in which there are far more galaxies than people.

 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.

 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.

 We find active super massive black holes at the centers of massive galaxies. Our galaxy also has its own black hole at its center measuring 2.6 million solar masses. Our black hole is not active today, but we presume it was active in the past.

 They're typically seen in starburst galaxies, where there's a lot of star formation and large stars don't last very long. They typically explode soon after they're made — where 'soon' is a million years.

 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,

 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.
