Astrophysicist and Star Talk host Neil deGrasse Tyson signaled his solidarity with LGBT communities with a short Twitter “lecture” earlier this week.

Tyson began his series of tweets with observations regarding rainbows, including Isaac Newton’s assignment of the colors seen in them, and also managed to reference Star Trek: The Next Generation before ending on a gracious note, as seen below.

The exact Rainbow any of us sees in the sky is entirely our own — a personal, yet communal gift from the laws of optics.

Rainbows are always the same angular size in the sky — they are various segments of a circle that is 84-degrees across.

A Rainbow forms only broadside to your line of sight. That's why the pot of Gold at its base remains eternally out of reach.

Isaac Newton, in Opticks (1704), published his discovery that white light is composed of colors – the colors in Rainbows.

If we had vision like @StarTrek’s Giordi, Rainbows would look twice as thick, and include parts of ultraviolet & infrared.

Newton assigned seven colors to the color-continuous Rainbow: Red-Orange-Yellow-Green-Blue-Indigo-Violet. Meet ROY G. BIV

Most people can take or leave Indigo as a Rainbow color, but Newton was mystically fascinated with 7, so we’re stuck with it.

And sometimes you will find colors of the Rainbow on flags. pic.twitter.com/fl9AJuJANK
