Around Our Cosmic Neighborhood

Humanity lives in a pretty awe-inspiring neighborhood. Look around and meet the neighbors. How far is it around the block, I wonder?

23 of NASA’s Most Beautiful Galaxy Pictures - Feast your eyes on these eye-poppers!
21 Incredible Cloud Nebula Pictures - These mind-benders are truly out-of-this-world.
Riding Light - This animation illustrates, from a human perspective, in realtime, the journey of a photon of light emitted from the surface of the sun and traveling across a portion of the solar system.
The Millennium Simulation - The video shows a journey through the simulated universe. On the way, we visit a rich cluster of galaxies and fly around it. During the two minutes of the movie, we travel a distance for which light would need more than 2.4 billion years.
100,000 Stars - This simulation shows the real location of over 100,000 nearby stars. Watch as 87 major named stars and our solar system are revealed and placed within the Milky Way galaxy.
Eyes of Exoplanets - On average, it is estimated that there is at least one planet for every star in the galaxy. That means there's something on the order of billions of planets in our galaxy alone. These planets outside of our solar system are known as Exoplanets. Explore stars in our galaxy known to have exoplanets orbiting them.
Galaxy of Horrors - NASA has also created these humorous, campy posters with information about the latest exoplanet discoveries. Free to download, these fun posters recall vintage horror movie ad posters. Click on the link, then point to any of the posters to get information about the exoplanet and download the poster if you want.
Satellite Map - Did you know that there are over 19,000 human-made satellites now orbiting the Earth?
