 We'll finish our 2017 review with a trip through Hubble's ultra-deep field. This visualization traverses the candle's ultra-deep survey field to showcase the varied appearance of galaxies and their three-dimensional distribution. The sequence features a dense cluster of galaxies about 6 billion light-years away and extends to galaxies at more than twice that distance. The changes seen in galaxies during the fly-through illustrate the change in galaxy structure and appearance over billions of years of cosmic history. Handels is one of the largest projects ever done with the Hubble Space Telescope. Astronomers and visual artists extracted over 26,000 galaxies from the Hubble Ultra-Deep survey and created a computer model based on the measured and estimated properties.
