(Whoops, this was supposed to post yesterday for #SaturdayScience... consider this a special #SundayScience!) What's up in the night sky this September? * Full moon September 13 and a new moon on September 28. * The September equinox is September 23, when there is equal length of day and night. It'll be the fall equinox for northern hemisphere folks, so look forward to longer nights for sky-gazing! * No Mars! Mars is in solar conjunction, meaning it is "behind" the Sun as seen from Earth. Solar gas emissions interfere with our radio signals to spacecraft at Mars, so we won't have contact with them until Mars moves further from the Sun (from our perspective).

What's up in the June nighttime sky? Tune in to NASA's What's Up to find out! * Jupiter reaches opposition--when Jupiter, Earth and the Sun are arranged in a straight line, with Earth in the middle--on June 10. The Gas Giant is visible all night and seems particularly big and bright! * Mark June 17 on your calendars--it will be a full moon and (if you can get a good peak at the western horizon) you'll be able to see Mars and Mercury appear very close together immediately after sunset. #SaturdayScience
