According to foreign media reports, the Andromeda galaxy 2 million light years away from earth is from the recent large spiral galaxy, the Milky Way is one of the astronomers for easy observation research objects. Currently, astronomers with the help of herschel infrared space telescope, observed the Andromeda galaxy intricate cold dust spiral path.
The European space agency's herschel space telescope his latest dust ring cold vortex
In this artist jang hyuk herschel infrared space telescope observations of the Andromeda galaxy latest photo, present a clear structure of star formation path, cold warm interstellar dust gathered around in the Andromeda galaxy kernel, the region formed stars are born.
In far away from the galaxy kernel cosmic dust where there is extreme cold, about a few degrees above absolute zero. The kernel to birth of new stars in galaxies, but the rate of star formation is very slow, embedded in the larger proportion of the annular structure with dust.
Recent observations of the Andromeda galaxy is a variety of instruments in combination with herschel space telescope image taken as a result, the photoelectric detection array camera and spectrometer (PACS) and spectral photometric imaging receiving apparatus (SPIRE) highlights the most densely populated regions of the star birth (the blue and white part of the figure), at the same time, dark red and orange is the coldest area of the part.
Image at the bottom of the picture is only observation data from the receive spectral photometric imaging instrument, the instrument with maximum wavelength range.
