Encircling the Solar System are the inner and outer planets, Kuiper
belt, Oort cloud, Alpha Centauri star, Perseus Arm, Milky Way
galaxy, Andromeda galaxy, other nearby galaxies, the cosmic web,
cosmic microwave radiation, and invisible
plasma produced by the Big Bang at the very edges.
Created by musician and artist Pablo Carlos
Budassi, the image is based on logarithmic maps of the Universe put
together by Princeton
University researchers, as well as images produced by NASA based on
observations made by their telescopes and roving spacecraft.
The Princeton team, led by astronomers J Richard Gott and Mario
Juric, based their logarithmic map of the Universe on data from
the Sloan Digital Sky Survey.
Over the past 15 years it has been using a 2.5-metre, wide-angle optical
telescope at Apache Point Observatory in New Mexico to create the most
detailed three-dimensional maps of the Universe ever made, including spectra
for more than 3 million astronomical objects.
Logarithmic maps are a really handy way of visualising something as
inconceivably huge as the observable Universe, because each increment on the
axes increases by a factor of 10 (or order of magnitude) rather than
by equal increments. The Princeton team published them in
the Astrophysical
Journal back in 2005, but you can browse through and
download them at this
website.
While incredibly helpful, logarithmic maps aren't much to look at,
so Pablo Carlos Budassi decided to make something a bit more palatable."
