Mauna Kea’s colorful universe

The Canada-France-Hawaii Telescope atop Mauna Kea produces some of the most stunning astronomical images ever seen. Find out how the images are created, and experience the beauty of these celestial objects for yourself.

Seeking other Earths

More than one hundred extrasolar planets like Jupiter have been discovered, but what everyone really wants to find are “exo-Earths” orbiting other stars. Any day now, say astronomers.

Warm and not so fuzzy

NASA’s fourth and final Great Observatory, the Spitzer Space Telescope, is opening astronomers’ eyes to planets, stars, nebulae, and galaxies by zeroing in on the infrared radiation they emit.

Barnard’s Milky Way

A 1927 atlas and catalog by famed observer Edward Barnard helped astronomers discover that dark patches in the Milky Way are interstellar dust, not “holes in the sky.”

Extreme imaging

Braving the elements and high altitude, a pair of amateur astrophotographers journeyed to the summit of Mauna Kea in pursuit of dark skies and returned with spectacular images.

A League of its own

Since 1941, the Astronomical League has been the spearhead for amateur astronomers in the United States. Take a behind-the-scenes look with the organization’s executive secretary – you might be surprised at the number of areas in which the League is active.

Celestron’s Advanced Series telescopes

The telescopes used by amateur astronomers today are as good as they’ve ever been. Can these telescopes really be made any better? Celestron says yes, and after testing their newest Newtonian and Schmidt-Cassegrain models, so do we.
