Skywatching in January

The dawn sky features the two brightest objects in the night sky after the Moon: the planets Venus and Jupiter. Venus is the brilliant Morning Star, while Jupiter, which is much bigger but also much farther, is not quite as dazzling. The Moon passes them twice during the month, adding to the early morning spectacle. Between those encounters, the Moon passes through Earth’s shadow, creating a total lunar eclipse. More skywatching information is available at StarDate.org

Moon Meanderings


This artist's concept shows how Kepler Space Telescope discovers planets in other star systems. The telescope looks for a planet to pass in front of its star, blocking a bit of the star's light, making it look slightly fainter than normal. (Kepler operates from Earth orbit, so it never sees any star as more than a pinpoint of light, however.) Kepler has discovered thousands of confirmed or possible planets, even though it is a relatively small telescope. Even smaller telescopes on the ground also are discovering exoplanets.
