Since its launch five years ago, the Galaxy Evolution Explorer has photographed hundreds of millions of galaxies in ultraviolet light.
... as the archetypal merging galaxy system and are used as a standard against which to validate theories about galaxy evolution. An international group of scientists led by Ivo Saviane from the European ...
... (HST) images of an exotic type of active galaxy known as a "post-starburst quasar" show that interactions and mergers drive both galaxy evolution and the growth of super-massive black holes ...
... past found nine young, unusually compact galaxies, each weighing in at 200 billion times ... new images should lead to a better understanding of the evolution of galaxies early in the life of the universe ...
... collide is essentially the same as star formation inside galaxies, meaning that the intergalactic medium can be a used as a simpler, more accessible laboratory for the study of stellar evolution.
... of a nearby rich galaxy cluster. Collectively they will provide a key database for studies of galaxy formation and evolution. This survey will also help to compare galaxies in different environments, ...

... 5 billion year-old globular clusters in the Virgo cluster of galaxies. One of the results of these discoveries led astronomers to understand more about the life and evolution of cannibal galaxies.
... new measurement indicates that magnetic fields may play a more important role in the formation and evolution of galaxies than we have realized," said Arthur Wolfe, of the University of California-San ...

The researchers found that the distant galaxy, which is typical in many respects to others at that epoch, shows clear signs of ...
... of a large population of similar objects. "The LAT provides us with a unique probe of the galaxy's pulsar population, revealing objects we would not otherwise even know exist," says Fermi Gamma-ray ...
NASA's Galaxy Evolution Explorer has lifted the veil off a ghost known to haunt the local universe, providing new insight into the formation and evolution of galaxies.
