Night-thinking 

A few questions: 

  • Why does it get dark at 6 pm? 
  • Is it because Nicaragua is closer to the equator? 
  • Is it dark at 6 year-round?
  • This isn’t because they don’t observe daylight savings, right?
  • Do I just not understand how the sun works?

Can an astronomy nerd draw me a diagram, please? Space physics is difficult for me to comprehend, y’all.

    My last week in Alaska it got dark at 10 pm and I was like “EXCUSE YOU. IT’S NOT NIGHTTIME YET.” I’m sure the winter would devastate me but I’ve chosen not to care. Anyway, I will try to google space physics sometime.

    I researched this because I’m a librarian and it’s what we do. Disclaimer: this science answer sounds Greek to me:

    On the equator of the rotating spherical Earth, the Sun (and all celestial objects) intersect the horizon vertically. As you move away from the equator, they rise and set at increasingly shallow angles (which also depend on the declination of the object). The result is, on an equinox, at the equator the Sun is 15° below the horizon after one hour, while at 45° latitude the sun intersects the horizon at 45°, causing the Sun to be only about 10.5° below the horizon after an hour. Since it doesn’t move below the horizon as rapidly, twilight lingers longer.

    And yes, apparently the sun rises/sets pretty close to the same time year-round at the equator.

    I found diagrams, but they are very sciency and don’t make sense to me but:

      And of course you’re still north of the equator, so the sunset/sunrise time might vary by an hour-ish maybe throughout the year? That’s a total guess though.

      I will try to comprehend this explanation. I still need a drawing, and now I’m starting to think I may need some sort of 3D animation lol
