|This journey begins with a spectacular view of the Milky Way, our galaxy. Then the zoom leads us to the center of the southern constellations Scorpio and Sagittarius. And we move to a region of star formation known as NGC 6334 or Nebula Cat's Paw. These images are taken by the VISTA telescope on Earth, observing in the infrared part of the electromagnetic spectrum. And finally, a new vision of the region taken at submillimeter wavelengths with Artemis camera APEX telescope (Atacama Pathfinder Experiment). APEX is a telescope 12 meters in diameter, located at 5100 m altitude on the Chajnantor plateau in the Atacama Desert in Chile. It operates at millimeter and submillimeter wavelengths, i.e. between infrared light and radio waves in the electromagnetic spectrum. The observations in the infrared allows astronomers to peer into the cold universe. In these images the region of the formation of stars of Cat's Paw Nebula, we see orange-red light detected by ArTéMis. This color corresponds to the emission of 0.35 mm of dense clouds of interstellar dust grains. Then overlay, we see the same images in near-infrared view from the VISTA telescope at Paranal.|
nota: ArTéMiS means: Architectures bolometers telescopes with large field of view in the submillimeter domain Soil (bolometer arrays for submillimeter telescopes with large field). Bolometers (Greek Bole, radiation, and metron, measure) are sensors that measure the quantity of energy received from a source of electromagnetic radiation.
Video: Dazzling trip down the Nebula Cat's Paw. This trip just a minute, starts with a spectacular view of the Milky Way, our galaxy. Then, the zoom leads us to the center of the southern constellations of Sagittarius and Scorpio. These images were taken from the Atacama Desert (Chile) by telescopes Vista (infrared) and Apex (millimeter and submillimeter wavelengths). The millimeter and submillimeter wavelengths can highlight the cooler regions. Nebula Cat's Paw (NGC 6334) is visible in the sky of the southern hemisphere, in the constellation of Scorpio. Located 5,500 light-years from Earth, this huge cloud spans about 50 light-years. The cat's paw Nebula was discovered by British astronomer John Herschel in 1837. video credit © ESO
