Using advanced technology, NASA has found one of the largest galaxy clusters discovered in human history, according to the Daily Mail.
With the use of NASA's Wide-field Infrared Survey Explorer and Spitzer Space Telescope, we humans can take a look at galaxy clusters believed to be a quadrillion times larger than our sun, according to EarthSky.
"Based on our understanding of how galaxy clusters grow from the very beginning of our universe, this cluster should be one of the five most massive in existence at that time," said Peter Eisenhardt of NASA. Galaxy clusters hold hundreds of thousands of galaxies within them.
An interesting aspect to note is that light takes time to reach Earth, meaning the scene we view with WISE may not be what actually exists right now. Scientists say that the images of the cluster are of what it was 8.5 billion years ago, a time when the Earth had not even begun to form, according to Gizmag.
The tools developed by scientists help to decode the light sent from far away so that it makes visible images.
"It's the combination of Spitzer and WISE that lets us go from a quarter billion objects down to the most massive galaxy clusters in the sky," said Anthony Gonzalez, with the University of Florida-Gainesville.
