The name Mira translates to “The Wonderful” or “The Amazing One”. This famous star was easily visible from my suburban home, this morning, even with a bright gibbous moon nearby. Just 100 days ago this star was so dim that I would have needed a telescope to see it even from the darkest of skies.
Mira was the 1st star discovered to change its brightness. This Long-Period Variable Star is 250 times brighter at maximum than at minimum. Mira’s brightness variation is so intense that its Spectral Type changes from a M5 to an M9 during its 332-day cycle.
Mira is near the end of its nuclear life. This Red Giant star has used up its helium (fused into carbon and oxygen) and is now entered a “Thermal Pulse Phase”. This phase is short lived, and Mira will eventually end up as a white dwarf with an impressive planetary nebula. Currently the star’s pulsations have expanded the size of Mira that if placed where our sun is, it would engulf the orbit of Mars in visible light and nearly reach the orbit of Jupiter in infrared light.
Mira is also a double star. Its smaller companion (VZ Ceti) is also a variable star which changes in brightness from 9.5 to 12.0 magnitudes. It is close enough to Mira that some of Mira’s expanding atmosphere is being pulled into the smaller blue subdwarf star. In the drawing it is the star adjacent to Mira at 8 o’clock.

My little wooden rocking horse which has a special place on the kitchen cupboard. Strange how you really start to think about an object when you really look at it. As I was drawing the little horse I was thinking that this was once a tree and it inspired the words which I had written on the opposite page.
Mr. J.C. Roth taught high school physics at Uni High -- USDHS -- University of San Diego High School. I have no idea what years he taught there, but he was a great teacher who I totally underappreciated.

So, I just showed this to my daughter. I told her it is the fairy queen. She smiled a really big smile! Then I asked her if she would like a crown and a dress like this one (I think I could actually make both). She insists she wants the Belle (Disney Princess) dress from Toys R Us. Oh, kid.
