HTTP:: Gorgeous Infrared View of the Milky Way Revealed
--------
Two of the most advanced telescopes orbiting the planet or the Sun today were launched this year aboard an Ariane 5 delivery system by the European Space Agency (ESA). One of them is the Planck observatory, whose mission is to analyze the Cosmic Microwave Background (CMB), while the other is the flagship mission, the Herschel Space Telescope. It is able to photograph the Universe in the far-infrared wavelengths, and one of its first images is of the Milky Way, featuring unprecedented details. While taking the shot, Herschel was placed in a special scanning mode, the BBC News reports. The main goal of the advanced observatory is to distinguish details about early star and galaxy formation that are invisible to other telescopes, such as the famous Hubble. In order to do that, it needs to be cooled close to absolute zero, and also to orbit the Sun in a Lagrangian point (L2), so that residual light coming in from the Moon, Earth and the Sun is kept away from its sensitive det!
ectors. In its latest image, the spacecraft used its three infrared detectors to image collapsing clouds of gas that fell under their own gravitational pull to create young, blue stars. The scanning mode Herschel was placed in meant that two of its cameras, the PACS (Photodetecting Array Camera and Spectrometer) and SPIRE (Spectral ...
