An international team of astronomers published a picture of the Milky Way, which allows to consider more than a billion individual stars. Image was presented at the National Astronomical Conference in Manchester March 28, 2012, according to the website of the University of Edinburgh.
The image was made up of thousands of individual images obtained by the two observatories. On the resulting disc-shaped galaxy, our photos are presented in the form of an elongated cut - the way it looks from Earth. The northern part of the celestial sphere (in the picture on the right) was photographed by telescopes in Hawaii and works as part of the British project UKIDSS / GPS. South (left) part was composed of the images of the telescope VISTA, located in Chile.
Photographing was conducted in the infrared range. The light with a longer wavelength goes around small obstacles is better, so images in the infrared suffer less from scattering of interstellar gas.
Data collection took the researchers nearly a decade. Image currently has a size of about 150 gigapixel, but judging by the presence of a small number of spaces, this figure will increase. This information will be integrated into the international astronomical database VISTA Data Flow System, which will be available for the study of thousands of astronomers around the world.
Billions of stars in the photos, is only a small part of all the stars of our galaxy. Their total number is estimated to be currently in the 200-400 billion.
