At the farthest limits of the universe discovered four strange ...
Space Infrared Telescope Facility Spitzer looked remarkably far in space and time, to 13 billion light years away - in other words, in an era when the entire universe was about 700 million years old. Optical Hubble ever seen, and the more ancient galaxies - but that said, this time Spitzer very unlikely for them.
According to astronomer Giovanni Fazio (Giovanni G. Fazio), «Hubble has revealed one of the first protogalaxies - but nothing like this... We may have found a ... Unfortunately, the scientist explained that he has in mind - perhaps it is about what these objects might result from the merger of the first generation of galaxies.
Spitzer filmed just four ancient galaxies are much more brightly shining in the infrared than in visible. The reason for this ... This may be an indication of increased amounts of interstellar gas and dust in galaxies - fueling the radiation of stars, they begin to radiate in the infrared wavelengths. Secondly, the galaxy may contain an exceptional number of old red stars and dark. Finally, the effect may be related to the cosmological redshift: because of its distance from us in an expanding universe, these galaxies fly away from us at great speed, and their movement shifts the spectrum of radiation coming from them to the red. Rather, in this case are all three factors at once, although the exact estimate of their contributions can not yet be.
Scientists plan to examine several possible models in the theory and, after the necessary calculations, answer the question about the nature of the ... Especially since they form in space is closely related to each other group, which means that all this is no accident. Perhaps the work will be able to connect and powerful telescopes, ground-based observatories - in the end, I wonder how this ...
