This was recently in the news. If you took a picture of the Sun every day, always at the same hour and from the same location, would the Sun appear in the same spot in the sky? A very fine image, compiled by astrophotographer Giuseppe Petricca from Italy, proves the answer is no. Source - user link on phys.org Duh, right?

That's really cool. Knowing about the way Earth's tilt and orbit affects its orientation relative to the sun is one thing but that's a great way to visualize it. "Dangerous toys are fun, but you could get hurt!" |

I like those long-exposure photographs they take at night out away from city lights. The stars and planets form streaks across the sky. It doesn't matter if the glass is half empty or half full. There's clearly enough room for more wine. |

Once again, astronomy leads to pretty photos.
They do this with the moon, too. If you want to shine like a sun, first burn like a sun. |
