A new camera on a telescope in the Southern Hemisphere has captured a stunning image of the Cat's Paw Nebula, offering a colorful and detailed view of a star-forming region of the Milky Way.

Released by the European Southern Observatory, the new photo of the Cat's Paw Nebula located about 5,500 light-years from Earth is one of the first shots taken by ArTeMiS — a submillimeter-wavelength camera added to APEX, the Atacama Pathfinder Experiment in Chile. ESO officials also produced a video fly-through of the incredible Cat's Paw Nebula view using the new camera observations.

The new instrument is expected to help scientists create more detailed wide-field maps of the sky in a shorter amount of time, ESO officials said in an image description. But the installation of the new hardware was no cakewalk.



"The commissioning team that installed ArTeMiS had to battle against extreme weather conditions to complete the task," ESO officials wrote. "Very heavy snow on the Chajnantor Plateau had almost buried the APEX control building."

The staff had to use an improvised road in order to transport and install the instrument in its proper location.

The research team also battled the weather when it came time to observe using ArTeMiS. The light observed by the camera is absorbed by water vapor in Earth's atmosphere, according to ESO officials. Because of this, the scientists had to wait for dry weather before testing out the instrument.

Since its initial commissioning, researchers have used ArTeMiS for scientific projects including one that produced the new photo of the Cat's Paw Nebula.

"This new ArTeMiS image is significantly better than earlier APEX images of the same region," according to ESO officials.

ArTeMiS is a new wide-field submillimetre-wavelength camera that will be a major addition to APEX’s suite of instruments and further increase the depth and detail that can be observed.
