The stunning image from space shows more than three billion stars in a single image
The Dark Energy Camera has recorded more stars and celestial bodies in Chile than ever before. The images show just 6.5 percent of the night sky.
New images of space and the Milky Way show more celestial bodies than ever before: more than three billion stars and galaxies can be seen in the images. The images were taken using the Dark Energy Camera mounted on a telescope in Chile.
Detailed star “group photo”
The camera had recorded the southern hemisphere skies for more than two years. The resulting images show exceptionally detailed stars in the Milky Way as well as distant galaxies.NOIRLab of the National Science Foundation released the images on Wednesday. The US government funds NOIRLab, which stands for National Research Laboratory for Optical and Infrared Astronomy, and it researches, among other things, optical and infrared astronomy. This is an experimental part of astronomy that uses infrared radiation emitted by celestial bodies.
It’s like taking a group photo, says lead researcher Andrew Sedgarry, not only being able to distinguish each individual but also the color of their shirt. He is a graduate student in physics at Harvard University. “Although I stared at images with tens of thousands of stars for many hours, I’m not sure I realized the magnitude of those numbers,” said Sedgari.
Only 6.5% of the night sky has been photographed
According to the researcher, only 6.5 percent of the night sky was photographed during the Sky Survey. This scan systematically searches for objects and their layout. The latest survey includes the results of a study published in 2017 that identified two billion celestial objects, most of them stars.
The Milky Way contains hundreds of billions of stars […]. Mapping and cataloging these objects is a daunting task,” says NOIRLab. According to Sidjari, the survey is the largest catalog ever produced by a single camera in terms of the number of observed celestial bodies.
