Happy Perihelion Day!
This evening, Jan. 2, at 7:38 PM EST, the Earth will be at the point in its orbit where it's closest to the sun.
(in case you need a reason for continuing bacchanalia. 🙂 )
After talking to my students about how rockets work, I thought I would show them my rocket tricycle (powered by a CO2 fire extinguisher).
Don't be misled by media hype about a planetary alignment. Most people will only see Venus and much-fainter Mars. Mercury and Jupiter are very low in the bright glow of twilight and will likely need binoculars to see them. Uranus is invisible to the naked eye. So, no biggy.
Happy Perihelion Day!
This morning, 1/4, at 11:17 AM EST, the Earth was at the point in its orbit where it's closest to the Sun.
There's a full moon tonight. But if you go outside around 4:30 to 5:00 AM EST (3:30 - 4:00 AM CST), you'll see that the moon doesn't look full anymore. Part of it will be dark because it is in the Earth's shadow — a lunar eclipse.
For all of you old-timers out there, today is the 65th anniversary of the launch of the first artificial satellite into orbit. Sputnik 1 was launched on this date in 1957. That is generally regarded as the start of the "space age." What do you remember of that?
Today is the 53rd anniversary of humans' first steps on the Moon. I was a young child at the time, but I remember it well.
