Description
Light gets redder as it climbs out of gravitational holes, and a star near the black hole at the center of the Milky Way conveniently demonstrates this beautifully. Join us for a discussion of gravitational redshift, a sci-fi discussion of time travel and body shifting, and a bit of Messier trivia.

The Pleiades
Combining three consecutive vowels and at least 1000 stars, this open cluster is no constellation but it does catch the eye with its bright blue, B-type stars in the prime of their half-million year lifespans. Partnering with the Hyades to form the Golden Gate of the Ecliptic, let the Pleiades be your gateway to the prime of your life. Find your way on your walk about the galaxy with this bright asterism near the vernal equinox. The Pleiades, confidence in motion (Subaru).
