stop working, the Herschel Space Observatory European Space Agency noted the merger of two large galaxies, helping to explain why there are giant elliptical galaxies in the Universe. The discovery was published today in the journal Nature.
Along with the Hubble and NASA’s Spitzer, more telescopes on Earth, we observed two large galaxies called HXMM01, who met and began creating stars. Over time, both will calm down and form a super elliptical galaxy.
“We are seeing a juvenile phase of the life of these galaxies – an explosion of activity teenager will not last long,” said Hai Fu astronomer at the University of California at Irvine.
Thanks to Herschel infrared detectors designed to capture as bandwidth for infrared light could be seen through the dust surrounding the merger.
Galaxies are
11,000 million light years from Earth, when the universe was about 3,000 million years. At first, astronomers thought that the image was a reflection receiving ghost of a single galaxy, however after further investigation, they realized that they were actually observing the merger of two galaxies. Then they noticed that between the two was creating 2,000 stars per year – much compared to the Milky Way, for example, which creates a three per year.
This observation runs counter to the most popular theory to explain the creation of giant galaxies, which indicates that a large galaxy absorbing smaller galaxies, however, here are two that are as big as they are merging with each other.
