Here is a picture of a comet, comet Hyakutake in 1996
There is a nice comet once every few years.
What do you see?
- Observer: Dianne Marshall
- Location: Fairbanks, Alaska
- Date: March 28, 1996 08:15 UT
One minute exposure, 50 mm lens, Kodak 1000 Gold film, F4.5, lots of sky glow but no direct aurora. Time about 11:15 AST
- It looks like a fuzzy ball.
- The ``best'' comets are fairly bright, so a comet is not difficult to
see if you get away from lights.
- It has a tail, but the tail is difficult to see.
- Bad: moonlight; city lights.
- Good: your eyes.
- They are very sensitive when adapted to the dark.
- The most sensitive part of your retina is away from its center.
- Thus to see the tail, you should look a little above it or below
it or to the side.
Here is an image of Halley's comet.
Where does it come from? What makes it shine? What is it made of? How big
is it? What makes the tail?
