This One’s for my Mum.

When I was a little tacker about 8 or 9 y/o, I enjoyed looking out at the stars from my bedroom window.

One night my Mum joined me, and I remember her pointing out the Pleiades and telling me the story about how big bad ol’ Orion would never catch those ladies.

I always liked that story and this has always been my favourite constellation. Sadly, Mum passed away peacefully a few weeks back, after a fine innings at 93, so this one’s for her.

The Pleiades, also known as the Seven Sisters and Messier 45, are an open star cluster containing middle-aged, hot B-type stars located in the constellation of Taurus. It is among the nearest star clusters to Earth and is the cluster most obvious to the naked eye in the night sky.

The cluster is dominated by hot blue and luminous stars that have formed within the last 100 million years. A faint reflection nebulosity around the brightest stars was thought at first to be left over from the formation of the cluster (hence the alternative name Maia Nebula after the star Maia), but is now likely an unrelated foreground dust cloud in the interstellar medium, through which the stars are currently passing.

Computer simulations have shown that the Pleiades were probably formed from a compact configuration that resembled the Orion Nebula. Astronomers estimate that the cluster will survive for about another 250 million years, after which it will disperse due to gravitational interactions with its galactic neighborhood.

“The Pleiades, companions of Artemis, were the seven daughters of the titan Atlas and the sea-nymph Pleione. According to Greek Mythology, they were translated to the night sky as a cluster of stars, the Pleiades.” (Wiki)


“The constellation is now known in Japan as Subaru (“to unite”). It was chosen as the brand name of Subaru automobiles to reflect the origins of the firm as the joining of five companies, and is depicted in the firm’s six-star logo.”
