An interactive map of 200,000 light-year galaxies…
Based on information gathered over 20 years, Johns Hopkins University has released an interactive map of the universe that is available to anyone who has missed access to scientists only.
When viewing the page, you cannot manipulate the entire diagram interactively. To manipulate the map, click on the bottom right function (examine the map). At 1.5 billion light years away, elliptical galaxies that appear yellower and brighter than whirlpool galaxies are spreading. Spiral galaxies are no longer detected and their filaments are less visible. At 7 billion light years away, it is becoming increasingly difficult to see from Earth, but the blue quasar is visible.
After 10 billion light years, the blue photons emitted by the quasar also increase due to the cosmic scattering, making it appear red. Further out, the universe is filled with hydrogen gas, reaching a region called the Dark Ages where visible visible light is blocked. Keep scrolling, and at the end of 13.7 billion light years there is a flash right after the Big Bang. This light is amplified by the expansion of the universe and comes as radio waves. This is called the cosmic microwave background radiation. Relevant information can be found here.
