Ask the Astronomer

Q. Since Venus is just coming up in the dawn twilight, I’m curious to know when a planet such as Venus becomes our ‘morning star’ and then the evening star?

A. There are no seasons or months in which planets regularly appear in our sky. The visibility of planets depends on what side of the sun they are on in comparison to Earth. Apart from a visit to Flandrau’s planetarium I recommend using a planetarium program on a computer (use a solar system and a local horizon type view). Programs available for personal computer use include: StarryNight Enthusiast (Mac or PC, go to www.starrynight.com), and Voyager 4 or Voyager 3 (Mac or PC, go to www.carinasoft.com). If you don’t want to spend any money, there is also ‘Celestia,’ a free planetarium program. It is available at www.shatters.net/celestia (older versions available at their FAQ site).

Citizen Online Archive, 2006-2009

This archive contains all the stories that appeared on the Tucson Citizen's website from mid-2006 to June 1, 2009.

In 2010, a power surge fried a server that contained all of videos linked to dozens of stories in this archive. Also, a server that contained all of the databases for dozens of stories was accidentally erased, so all of those links are broken as well. However, all of the text and photos that accompanied some stories have been preserved.

For all of the stories that were archived by the Tucson Citizen newspaper's library in a digital archive between 1993 and 2009, go to Morgue Part 2
