Year On Earth Video
A year on earth is measured by one complete trip around the sun. Seems simple enough but there is a problem. The earth doesnt travel in a path around the sun that returns it to its starting point.

HubbleSite - Out of the ordinary...out of this world.
The Webb Space Telescope, Hubble's successor, will see in infrared, the light emitted by the farthest objects we can detect. Learn about Webb, its technology, and the science it will reveal.
Chromoscope - View the Universe in different wavelengths
Ever wanted X-ray specs or super-human vision? Chromoscope lets you explore our Galaxy (the Milky Way) and the distant Universe in a range of wavelengths from gamma-rays to the longest radio waves. Change the wavelength using the slider in the top right of the screen and explore space using your mouse. For more information we have a quick video tour or you can read more on our blog .

Interactive 3D model of Solar System Planets and Night Sky
Tutorial : Part 1 | Part 2 | Part 3 | Part 4 | Age | Distances | Bibliography | Relativity The current best fit model is a flat ΛCDM Big Bang model where the expansion of the Universe is accelerating , and the age of the Universe is 13.7 billion years. Back to top. The evidence for the Big Bang comes from many pieces of observational data that are consistent with the Big Bang. None of these prove the Big Bang, since scientific theories are not proven. Many of these facts are consistent with the Big Bang and some other cosmological models, but taken together these observations show that the Big Bang is the best current model for the Universe.
