Moscow. 12th of August. INTERFAX.RU – Group of astrophysicists from the project Galaxy And Mass Assembly (GAMA) in the course of the study concluded that two billion years the number of released energy in the universe is halved, indicating that slow her death, according to N + 1 link to the website of the European Southern Observatory.
The researchers studied using four land and two orbiting telescopes and observatories 221.4 thousand galaxies. Based on the collected data, they concluded that the energy produced at each site in the modern universe ranges from the ultraviolet to the far infrared, is less than half of the one allocated two billion years ago.
With the help of telescopes, scientists managed to create the most comprehensive database of galaxies in the local Universe in the area of the sky more than 360 square degrees. Also, observations have shown that since the 1990s, the amount of energy released by a majority of galaxies steadily decreasing at all wavelengths of electromagnetic radiation, which, according to the researchers, says the slow death of the universe.
In order to track the evolution of energy generation in time for Astrophysics smashed all the galaxies into three groups with different levels of the red shift, which allowed a peek at 0.8, 1.5 and 2.25 Gyr ago. The level of energy emitted is measured by assessing the total number of photons emitted recently compared with the amount previously thrown and scattered already partially reflected in space and cosmic dust.
The project GAMA was established to make the most detailed to date energy map of the Universe, as well as to model it in different moments of the past.
Most of the energy that exists in the universe originated in the Big Bang. Part of it is preserved in a mass stars, but thanks to the fusion mass is gradually moving back into the energy radiated into space. On a very long wavelengths it is then re-emitted from the stars of the giant gas and dust clouds.
