Descripcion
English: The image shows a poster, meant for A0 printing or just enjoying on the screen.

The image is an artwork, created by me. It is compiled from multiple, free sources, listed at the 'original source' section. The image puts home (earth and our solar system) into perspective of the universe as far as we know it. As an astronomer, it is particular difficult to provide a sense, or a feeling of the scale of the universe and everything that surrounds it. This poster is meant to help the astronomically interested person to feel what it means to live in this universe.

The six artistic images on top and below as well as the milky way present a sense of the size of the known, nearby universe.

The Planets diagram sets the earth and other planets of the solar system into the perspective of roughly 500 extrasolar planets that have been found and confirmed so far. The diagram does not actually show the distribution of planets as it is in reality, it is strongly biased due to our limits in observing small planets and planets with a large distance to the host star.

The HR diagram puts the sun in relation of other, nearby suns. This diagram is also biased due to our limits of observing very cold, dark stars. The number of red dwars would outmatch the other stars by a huge amount, but we just can't see them. In connection with the HR diagram, the Galaxy image gives an impression how far we can see stars with our naked eyes in a clear, dark night without light pollution. The scale shows how far we can see stars, depending on their brightness.

The lower left and lower right diagram gives a perspective of the size of the universe, as it changes over time. The observable universe shows how the universe developed in the past. The other is an estimation how it might develop in the future. The scale of the x-axis is different, otherwise it would be possible to attach both diagrams by turning one of them by 180deg. The estimated distances and times are based on calculations before the most recent plank data was released. The diagrams should give a sense how the universe expands, and how large it actually is.

6 small images at the top and bottom: The not-annotated version is used and re-texted with a different font, matching the central galaxy image. The text information came from the annotated version. Some small errors were corrected though. File:Earth's Location in the Universe (JPEG).jpg Author: Andrew Z. Colvin

Planets Diagram: This diagram is visually my own work. Data from http://www.exoplanets.org/

HR-Diagram: This diagram is visually my own work. Data is from Hiparcos Cataloge: Roughly 55,000 nearest stars, closer than paralexe 5 mas minus some manual selected stars that got in the way in the image. Hiparcos data source: http://vizier.u-strasbg.fr/viz-bin/VizieR

Observable Universe and Reachable Universe: This diagram is visually my own work. I used the cosmic calculator to find initial values: http://www.astro.ucla.edu/~wright/CosmoCalc.html After that, I calculated the other information my self.

Background: The background is a derived version from the cosmic web simulation from the "The Millennium Simulation Project", Max Plank Institute for Astrophysics. http://www.mpa-garching.mpg.de/galform/virgo/millennium/ Copyright statement for the background image ( http://www.mpa-garching.mpg.de/galform/data_vis/index.shtml ): When material of this page is used, credit has to be given to the author(s) as well as to the Max-Planck-Institute for Astrophysics.
