Tips for stargazing
Here's what to look for to get the best view of the night sky, using Outside, Looking Up (OLU):
- Darkness: Although stars will start to appear soon after sunset, the night sky looks best once the sun has moved at least 18 degrees below the horizon, which is the end of 'astronomical twilight'. OLU displays these times once you choose a location.
- Moon: Strong moonlight will make the stars and planets harder to see in the night sky. Ideally, plan to go out when the moon is below the horizon, or look for a night when it's not illuminated so strongly (avoid days close to the full moon). OLU shows you the current moon illumination, calculated for 10pm each day, along with times for moon rise and set.
- Weather: It's hard to see stars when there are clouds! OLU gives you detailed forecasts for the next 48 hours cloud cover, along with general weather forecasts for the current week. Other factors that might affect your plans are rain, temperature and visibility forecasts.
- Aurora: If you live in the high or low latitudes it's worth keeping an eye out for strong aurora forecasts. Check the aurora page for details on how to view the polar lights.
- Light pollution: Light given off by large cities affects your view of the night sky. This site is a great tool for finding a dark area for stargazing.
