BEIJING, Sept. 9 (Xinhua) — Researchers have taken the first photos with a resolution of 3.2 billion pixels, the highest ever, the SLAC National Accelerator Laboratory said in a blog post. The cameras that take these pictures will be used in Stanford University’s Space-Time Heritage Survey telescope in Chile. The Space-Time Heritage Survey will be used to study dark matter and dark energy for “the highest-resolution astronomical film ever made”.
The Space-Time Heritage Survey telescope consists of 189 imaging sensors.
With a resolution of 3.2 billion pixels, it takes 378 4K televisions to display a photo in full size. The Space-Time Heritage Survey telescope can capture smaller objects that are “invisible” to other telescopes. It can see golf balls 15 miles away, with 100 million times the speed of the human eye.
What’s striking about the camera is that it has 189 imaging sensors with a resolution of 16 megapixels. These sensors are divided into 25 groups, 21 of which are used for imaging. Each set of sensors is worth up to $3 million, and the installation of all imaging sensors takes up to six months.
Camera assembly has not yet been completed and testing of the entire machine is expected to begin in mid-2021. (Author/Frost Leaf)
