The biggest photo ever taken: the camera has 3.2 billion pixels

Scientists plan to use this huge camera to capture comprehensive images of the southern sky as part of a study called the Legacy Survey of Space and Time (LSST).

The study will help scientists see our universe better than ever and solve some of the great mysteries of astronomy, such as how galaxies evolve and how they evolve. in which theories about dark matter and energy collide with reality.

The camera is set to make its final journey from Northern California to Chile's Rubin Observatory, but the Stanford team took some test photos to prove its tremendous power, according to

An image of a vegetable may not sound like technological evolution, but Vincent Riot, the defense room project manager at the Livermore National Laboratory in the Department of Defense, said the first photos are an incredibly important step. to demonstrate how the camera will work when shooting space.

“This is a huge milestone for us,” Riot said. “The focal plane will produce the images for LSST, so it will be the sensitive eye of the Ruby Observatory.”

The basic design of the camera is no different from that of ordinary smartphones: light emitted by an object or reflected by an object is captured by light-sensitive components and converted to electrical signals. These signals can be translated into accurate pixel information to compose a photo.

What stands out in the design of this camera is that it has 189 individual light sensors, which bring all the 16 megapixel information.

In comparison, a standard mobile phone only brings up to 16 megapixels in total, the power at 1/189 level of this device.

The sensors are grouped into nine to form what the team calls a “science series.” Each sensor is 2 meters high and weighs 20 kilograms and costs $ 3 million.
