Here is a trip here in the Universe from the largest to the smallest distance.
The galaxies in the universe tend to congregate in large sheets and superclusters of galaxies surrounding large voids, which gives the appearance cellular universe.
This distance is equal to 10 yottameters.
If we can assume that the universe at very large scale is homogeneous, its screen becomes apparent on scales beyond 300 million light-years. The first level of structuring is a form that can not be easily described. Astronomers speak and walls, filaments, sheets or crepes,... to describe the morphology of the concentrations of galaxies, and structural foam, sponge, cloth spider to mention the very fabric of the universe.
100 million light years is the distance at which we can see the galaxy clusters.
This distance is equal to 1 yottameter.
Where filaments meet several or more layers, the concentration of galaxies is higher, reflecting the structures more easily identifiable, and appear as aligned in chains. They are the ones who take the name of superclusters.
Pegasus-Pisces A Horologium-Reticulum, Hydra-Centaurus (Great Attractor), Shapley Concentration,...
At 10 million light years away, a galaxy is seen as a point.
This distance is equal to 100 zettameters.
The current picture of galaxies is in fact very far from that in the past made universe islands. archipelagos of stars.
A 1 million light years away you start to see the disk of a galaxy.
There are so many galaxies in the observable universe, they are part of a broad range of masses and dimensions, and take a wide variety of forms.
At 100 miles light years away we see the structure of galaxies, the arms, the central disc,...
The intergalactic gas is collected in the galactic disk, in which the stars meet.
In the Milky Way, it was born an average of four or five stars each year.
Two out of three times, the stars belong to a couple, where both components revolve around their common center of gravity.
A 100 light years away we see the distribution of stars of a galaxy.
The stars are unevenly distributed across the sky. They include first galaxies, and the white trace in which the galaxy appears to us is the manifestation of such clusters.
A 10 light years away we see each point representing the stars in the galaxy.
The stars are born in clusters from the fragmentation and contraction of portions of cold interstellar clouds.
1 A light-year away from our galaxy the sun appears to observers outside our galaxy.
In the vastness of the universe, the Sun is simply a star among millions of others. And, for the Earth, on the contrary, it is the center around which it revolves, and his home life.
A 1000 billion km away from our galaxy, the sun appears a little larger to observers outside our galaxy.
Just like our Sun, the stars are masses of plasma (gas increased to very high temperature), to form generally spherical or ellipsoidal, rotating on themselves, extremely bright, and whose energy is radiated to the essentially in the visible part of the electromagnetic spectrum.
100 billion kilometers, the distance that fully understands the orbits of the planets in our solar system.
Before Kepler, it was believed that the orbits of the planets were circular.
10 billion km is the distance that includes most of the orbits of the planets in our solar system.
Pluto and Charon are a couple of dwarf planets situated in the Solar System 5.9 billion kilometers. The couple performs its long circuit around the Sun in 250 years.
1 billion km, the distance that fully understands the orbit of asteroids in our solar system, it is located between Mars and Jupiter.
Asteroids are rocky bodies smaller than a thousand kilometers) devoid of atmosphere, which is mainly in the internal regions of the solar system, especially between the orbits of Mars and Jupiter.
100 million kilometers, the distance which covers almost the entire orbit of Venus. The second planet closest to the center of the solar system.
Venus revolves around the Sun at a distance of 108.2 million kilometers.
10 million km, the distance that has 10 times the orbit of the Moon around the Earth.
10 million km, the equivalent of 10 round-trip Earth Moon.
1 million km, the distance that fully understands the orbit of the Moon.
1 million kilometers, equivalent to 1 return Earth Moon. The diameter of the Sun is approximately 1.5 million kilometers.
100 miles kilometers is the distance at which we begin to guess our Earth.
100 miles kilometers, equivalent to 10 times the diameter of the Earth.
10 thousand kilometers, is the distance that includes an entire hemisphere of Earth.
The diameter of the Earth is 12,756 kilometers.
Thousand kilometers, the distance that includes the entire area of France.
Almost hexagonal in shape and average size, making it between the Atlantic and the Mediterranean, a narrow isthmus at the western end of the continent.
100 kilometers is the distance that includes a large part of a French department.
Metropolitan France has 22 regions, which are subdivided into 96 departments and 3 808 cantons. These regions are: Alsace, Aquitaine, Auvergne, Basse-Normandy, Burgundy, Brittany, Central Region, the Region Champagne-Ardenne, Corsica, Franche-Comté, Haute-Normandie, Île-de-France, Languedoc-Roussillon, Limousin, Lorraine, Midi-Pyrenees, Nord-Pas-de-Calais, Pays de la Loire, Picardie, Poitou-Charentes, the Provence-Alpes-Côte d'Azur (PACA) and the Région Rhône-Alpes.
10 km is the distance at which you can see a city like Toulouse.
Toulouse, a city in southern France, capital of the department of Haute-Garonne and the Midi-Pyrenees, situated on the Garonne and the Canal du Midi. The town of Toulouse is the fourth largest city in France.
1 km, the distance at which you can see a village like Auzielle in Haute Garonne.
Auzielle my village
100 meters is the distance at which one can see a quarter of a village.
Surface may show some 25 houses. My subdivision.
10 meters is the distance at which one can guess the leaves of trees.
Trees are perennials, woody, with the main stem or trunk, is at least 6 m. The redwoods from North America and eucalyptus from Australia may exceed 110 m, with trunks whose circumference is 26 m.
1 meter, the distance at which you can see the branches of trees.
The branch or twig supports the leaves of a tree or shrub.
