Daily cosmobite: Does the full Moon affect our behaviour?

October 7, 2014

Andrew Jacob
 The full Moon affects Earth only through its gravity and light. This might influence the time we go fishing or inspire us to write a pop song. However, there is no conclusive evidence that it affects crime rates, emergency ward admissions or lycanthropy.

The constellation Aquila, The Eagle, is high in the northern sky. In the northern hemisphere it is said to be flying south to escape the cold northern winter. Perhaps we should say it is flying south to escape the heat of our approaching summer.

Andrew Jacob
The CSIRO Astronomy and Space Science Radio Astronomy School for 2014 begins today near Narrabri.

Daily cosmobite: Mars and Antares

September 26, 2014

Mars is in conjunction with the star Antares on Sunday at 06:00am AEST. Watch Mars over the weekend as it approaches and passes close by Antares, the brightest star in the constellation Scorpius. The two are linked in name also - Antares is translated as "like Mars" or "rival of Mars" although the former seems to be preferred these days.
