Among the rarest of celestial events, transits of Venus have enticed generations of astronomers seeking to measure the scale of the solar system.
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.
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.
Dark streaks by the thousands run down the sides of valleys and craters on the Red Planet. Planetary scientists say they're dust avalanches, but could any of the streaks be caused by water seeps or springs?
Viewing Venus in transit
