Take A Look At This 10 Trillion Pixel Image Of The Night Sky
A photograph of the northern sky that weighs in at a whopping petabyte has become a treasure trove of information for astronomers.
Space is an impossibly massive zone that countless stars and planets reside in, and if you want to capture even a fraction of the sky then you re going to have to approach that challenge with some equally gigantic ideas. Astronomers across the world gathered for a chance to capture a photo of the northern sky according to SyFy, pooling resources over six years to create a 10 trillion pixel image.
trillion pixels, and makes up a
petabyte of data a thousand terabytes, or a million gigabytes.
Oh, it also has over
a billion galaxies in it. A. Billion.
Like I said: Vast.
It s the result of the DESI Legacy Imaging Surveys, maps of the sky made by the three observatories (the Dark Energy Camera Legacy Survey, the Beijing-Arizona Sky Survey, and the Mayall zband Legacy Survey, in combination with the orbiting WISE infrared observatory). They mapped the northern sky in seven colors, covering a third of the entire sky 14,000 square degrees, or the equivalent area of 70,000 full Moons on the sky.

It’s the result of the DESI Legacy Imagining Surveys, maps of the sky made by the three observatories (the Dark Energy Camera Legacy Survey, the Beijing-Arizona Sky Survey, and the Mayall z-band Legacy Survey, in combination with the orbiting WISE infrared observatory). They mapped the northern sky in seven colors, covering a third of the entire sky 14,000 square degrees, or the equivalent area of 70,000 full Moons on the sky.
The ultimate goal is to better understand dark energy, the mysterious substance that’s accelerating the expansion of the Universe, by looking at the distribution of galaxies throughout the Universe. They’ll do that by picking tens of millions of the billion galaxies in the data and getting follow-up observations with the Dark Energy Spectroscopic Instrument (DESI), which will take spectra of those galaxies and find their distances.

An international research team has released a giant 2D map of the universe, the National Astronomical Observatories of China (NAOC) under the Chinese Academy of Sciences said Thursday.
Conducted by the Beijing-Arizona Sky Survey (BASS) of the NAOC and the Dark Energy Spectroscopic Instrument (DESI), the study paves the way for the upcoming new-generation dark energy spectroscopic survey.
