This Milky Way image is part of a series of photographs taken from the Spitzer Space Telescope. The picture is accompanied by a textual overview of the Milky Way with specific attention given to the details of the picture. Several higher...

When we look at the night sky, we see stars and the nearby planets of our own solar system. Many of those stars are actually distant galaxies and glowing clouds of dust and gases called nebulae. The universe is an immense space with...

In 1995, scientists pointed the Hubble Telescope at an area of the sky near the Big Dipper. The location was apparently empty, and the whole endeavor was risky- what, if anything, was going to show up? But what came back was nothing...

The Old and 'Red' Distant Galaxies in this space telescope image are barely visible (though they are clearly marked). In addition, a detailed textual overview explains various specifics of the picture.

A basic overview of supernovas. Links to more information about starts, planets and other objects in our solar system and galaxy are included.

NASA's Chandra X-ray Observatory site features a photograph and explanation of a "cool" black hole in the Andromeda Galaxy (M31).

The story of the universe is told in this engaging site by the European Space Agency. The history of European space science is timelined with dates ranging from 1066 to present day. The birth of galaxies, the big bang, and the beginnings...

Chandra allows astronomers to view our galaxy and beyond in ways only dreamt of before. 14 interactive features are offered in this exciting look at cosmic phenomena.

Many of the objects you can see in the night sky are stars, large objects in space that produce light. Our galaxy, the Milky Way, contains more than 100 billion stars. Stars are so far away that their light does not reach us for years....

A set of podcasts outlining a four-step process for understanding the vastness of our universe, from the vicinity of the Earth and Moon, out into distant galaxies. Downloadable instructions and a handout are included, as well as...

Learn about galaxies: How old are they? How can we study things so far away? What is the most distant galaxy? What can we learn by studying distant galaxies?
