Predicting Today’s Sunset

DIGITAL EFFECT: Sun Rise to Set Fade scene off and reset time to approximately one hour before sunrise on -1500/10/31 with cardinal points on before fading the scene back on. Audience may predict where along the horizon the Sun will rise. Also, if possible turn on a 2D trail for the Sun for tracking the […]

Reconstructing Stonehenge

Gerald Hawkins guessed that if Stonehenge marked one alignment with a celestial object, the Sun, it might mark others as well, like the sunrise and sunset we just recorded, or the risings or settings of stars or planets. To test that suspicion, his hypothesis, Hawkins first had to “reconstruct” Stonehenge, at least on paper, to […]

Marking More Risings and Settings

We can give our planetarium the same information that Dr. Hawkins gave his computer. Right now the stars, Sun, Moon, (and planets, if you are using them) are positioned as they would be on today’s date, about 3500 years ago, about the time when the giant trilithons were erected. The first stages of Stonehenge were built […]

Tracking the Migration of Sunset

Well, there we are. We know what doesn’t work. It may be discouraging, but scientists who have an idea usually keep trying until they have exhausted every possibility. Optional: If you have time, you can call for other suggestions and try them now, like the Moon in different phases, or the planets.We have considered alignments […]

A Magnetic Earth Around A Magnetic Sun

VISUAL 19 (still): Symmetric Magnetic Field Idled around Earth [Fade off Symmetric Magnetic Field.] The Sun is a magnetic star. And Earth is a magnetic planet! VISUAL 20 (movie): Magnetic Field of the Earth, Field Detection[Show and play the video that accompanies the interactive Magnetic Fields activity].

Differential Rotation

VISUAL 12 (still): Intensitygram of Sun[Show, in sequence, an intensity-gram of the Sun.] We can learn more from sunspots by looking at images different than the type we see here. VISUAL 13 (still): Magnetogram of Sun This is the same Sun, but this is a magnetogram, showing the Sun’s magnetic intensity. You can see the […]
