Before sunup … Moon and planets

Over the next several mornings - February 7 to 9 - you'll find the waning moon sweeping past the planets Mars and Jupiter.

Watch online as 2 asteroids sweep close

How to watch online this week as 2 newly discovered asteroids - 2018 CB and 2018 CC  - sweep closer to Earth than the moon. You can catch one today - from Rome - starting at 20:00 UTC (2 p.m. CST; translate UTC to your time).

TRAPPIST-1 worlds likely terrestrial and water-rich

Terrestrial means more like Earth than Jupiter or Saturn. Water-rich means a potential for life. New insights about the 7 planets orbiting this nearby star.

Last quarter moon is February 7

Watch for the last quarter moon after midnight Tuesday, or early Wednesday morning. It'll be showing us half of its lighted half, or day side.

Before sunup … Moon and planets

Jupiter - brightest starlike object in the night sky now - will catch your eye first. Mars and the nearby star Antares are fainter, about equally bright, and both reddish in color.
