Venus is shining at its brightest in the low southwestern night sky just after sunset, making it a fine time for stargazers to observe the brilliant planet, weather permitting. Here is how to see Venus with the unaided eye, telescopes or binoculars.
04 December 2013, 05:31 PM ET
Venus is now the showiest it will be for all of 2013 and 2014 in either the evening or the morning sky. The planet is so bright that you can spot it in a clear blue sky before sunset, if your eye lands on the right point in the south-southwest.
04 December 2013, 01:01 PM ET
Scientists think the moon coalesced out of material blasted into space when a large object slammed into the proto-Earth in the solar system's early days. Determining the composition of Venus could help explain how this mega-collision went down.
