Curator’s Choice: Most Awesome Comment of the Day
This post is in response to the second (http://goo.gl/06eCjX) of two Community posts, asking for help in identifying the object in the sky. Our poster has a fondness for the legend of Nibiru, which led to a heated discussion in her first post (http://goo.gl/od8MvW), as is typical of the SoG+ Community! We just happen to think that Sparthir Kiwiwarrior resolution of this issue is full of win! By the way, welcome to our community Elisabeth Natividad Gutiérrez Alcalá We are glad you found the Outreach section and hope we continue to learn from each other and enjoy #ScienceEveryday 🙂

I came across a post from a young lawyer from Granada, Spain asking if it was indeed the moon she was seeing in a photo she took. It looked rather big and unusual. So I wondered if I could confirm it from here (all the way in New Zealand).
I had the date, time and location the photo was taken all I needed to do was:
1. Bring up Google Street View to find the direction (due West virtually).
2. Bring up Stellarium (http://www.stellarium.org/) and put in the right location, date and time and look West.
Wonderfully it was la Luna (the moon)!
So next is to answer why it appeared to be so big.
Well ever notice how the moon seems so big when it rises at night? This is known as the Moon Illusion. One idea is that it looks bigger because your eye has something to give it a scale (a building for example).
If you actually get a measurement you will see it isn’t bigger in fact it is about 1.5% smaller than when it is directly over head!
1. I added a red line on the Stellarium screenshot to show roughly where the horizon is.
2. I wish I could speak Spanish. My family decided to not continue speaking it when they came to New Zealand and it still makes me a little sad that they decided to stop speaking such a nice language.
3. Turns out Granada, Spain is exactly 12 hours different to us here in New Zealand currently. This means the time I set is 12 hours off the local time. 🙂
