Chasing the shadow of Venus
Among the rarest of celestial events, transits of Venus have enticed generations of astronomers seeking to measure the scale of the solar system.

Reclaim the night sky
A night sky made bright by artificial light is a fact of life for most skygazers in North America and elsewhere. Yet if backyard astronomers work with their communities, it’s possible to combat this problem.

Genesis planet
Astronomers are starting to think planets, and maybe even life, gained a foothold far sooner than previously believed — perhaps less than a billion years after the Big Bang.

Amateur CCD discoveries
When the first CCD cameras for amateur astronomers were introduced in the early 1990s, great excitement followed. After a decade of imaging thousands of celestial objects, what have amateurs contributed to the science? More than you might think.
