    With a telescope, the Moon is best viewed during other phases, especially half-moon, in which the craters and mountains cast their longest shadows. Cool Lamp.

    I just got a telescope for my birthday so I’m hoping the clouds clear here to see it. If not maybe tomorrow. I also got this great lamp!

    Saturday, April 16, 2022 Full Moon today — the first one after the March Equinox. The Sunday following that Full Moon is, by definition, Easter. This rule precludes solar eclipses from ever taking place on Easter Sunday.

    Hard time comprehending the universe? Just remember that it’s actually above everyone’s head.

    Not that anybody inquired, but to say the individual letters “N-C-A-A” (as in ) uses fewer syllables than to say “N-C-double-A”. So to utter “double-A” does not save you time.

    A reminder… Eighty years ago the city of Leningrad was under siege for 900 days. The Nazis severed all supply chains into the city and pummeled the infrastructure, ultimately leaving a million Russian civilians dead. Meanwhile…

    Last I checked, the rest of the Universe was in good shape. It’s Earth that’s got all the problems.

    The exact Rainbow any of us sees is entirely our own — a personal, yet communal gift from the laws of optics. That’s why Rainbows are **always** face-on. You’ve never seen one at an angle, which forever protects the Pot of Gold hidden at it base.

    Mid-19th century, a mysterious element was discovered in space nebulae. It emits deep Green, and was dubbed “nebulium."

    Rarefied gas just might be Irish: The element oxygen, in Aurora and in the near-vacuum conditions of space, radiates pure Green.

    Stars are not Irish: The laws of radiative physics conspire in such a way that there are no Green stars in the Universe. They come in three basic colors: Reddish, White, & Blueish.
