  Exploring Cassiopeia
Cassiopeia is one of the easiest constellations to pick out by looking for a very distinctive "W." The queen lies in the middle of the milky way offering a beautiful backdrop of faint stars for all looks.
Cassiopeia was the legendary queen of Ethiopia, known throughout the land for her elegant beauty.
Enraged by Cassiopeia's false bragging, the Sea Nymph's begged the God of the Sea, Poseidon, to punish the queen for her insults and conceit.

Cassiopeia is a northern constellation which Greek mythology considered to represent a vain queen.
Cassiopeia was the site of Tycho Brahe's supernova of 1572 (SN 1572), and is also the location of Cassiopeia A, the strongest radio source in the sky (other than the sun).
Cassiopeia A is the remnant of a supernova which apparently occurred in about 1667, although there is no record of it having been observed.

 * Beta Cassiopeiae - (Astronomy): Definition
With beta Cassiopeiae () and gamma Pegasi (), as the Three Guides, it marks the equinoctial colure, the prime meridian of the heavens.
Beta Cassiopeiae is known as Caph from the Arabic meaning ‘stained hand’, as it was thought by them to represent a hand stained with henna.
Shedar, Alpha Cassiopeiae, the southernmost star of the "W," is up and to the left of Gamma, while Caph, Beta Cassiopeiae, is at the eastern (here, the left-hand) end.

Cassiopeia is very easy to recognize thanks to its characteristic W shape: in comparison with Ursa Maior, it is on the opposite side of the Polar Star.
Appeared near kappa Cassiopeiae, the supernova reached the brightness of Venus and it was visible to the naked eye for sixteen months.
Cassiopeia, daughter of Arab son of Ermes, was wife of Cepheus, to whom she gave a daughter, Andromeda.

Mu Cassiopeiae is one of the most rapidly-moving naked-eye stars, and, in fact, belongs to a different class of stars than most stars visible from Earth.
Somewhat farther away than these three stars, but still relatively close to the Sun, is Beta Cassiopeiae, the rightmost star in the "W".
Midway through the animation, Beta moves enough to distort the familiar shape; after 50,000 years, longer than the scope of this animation, Cassiopeia would be largely unrecognizable.

In ancient mythology Cassiopeia was a proud queen, wife of King Cepheus and mother of the princess Andromeda, today she shares the heavens with these constellations.
Since Cassiopeia and the Plough revolve around Polaris on opposite sides, when one constellation is riding high in the sky the other is closest to the horizon.
The brightest star cluster in Cassiopeia is NGC-457 often called the 'Owl cluster' owing to its shape (NGC stands for New General Catalogue, a catalogue of star clusters, galaxies and nebulae).

 Rho Cassiopeiae
It lies in the southwestern part (23:54:23.0+57:29:57.8, ICRS 2000.0) of Constellation Cassiopeia, the Lady of the Chair -- southwest of Caph (Beta Cassiopeiae), south of Tau Cassiopeiae, north of Sigma Cassiopeiae, northwest of Schedar (Alpha Cassiopeiae), and east of M52, the Bubble Nebula, and Delta Cephei.
With its stars shaped in a "W," the northern Constellation Cassiopeia was named by the Ancient Greeks for the mother of Andromeda who claimed to be more beautiful than the daughters of Nereus, a god of the sea.
Cassiopeia's vanity so angered the sea god Poseidon that he had Andromeda chained to a rock of the coast as a sacrifice for Cetus (the monstrous whale) until Perseus rescued her.

Beta Leonis: (Denebola) translates as “Lions Tail” and it is of interest because it would appear that Denebola has faded by over a magnitude, since 1603, for no apparent reason as it is a pretty standard main sequence star.
Cassiopeia, the wife of King Cepheus, ruler of Ethiopia, was beautiful, arrogant and vain, and it was these latter two characteristics which were to lead to her downfall.
Poseidon considered that Cassiopeia should not escape punishment entirely, and placed her in the heavens in such a position that she circles the celestial pole in an upside-down position for half the time.

Cassiopeia, the Queen of Joppa (or, variously, Ethiopa) is on the opposite side of Polaris from the Big Dipper, and culminates at midnight in early October.
Beta Cassiopeiae, CAPH (Magnitude 2.3), is almost as bright as Shedar and stole the name of the whole W of the constellation.
Cassiopeia is also the location of Tycho’s Star, the great supernova of 1572, the most brilliant nova recorded in the past 500 years and one of the four known supernovae recorded in our galaxy.

 Seasonal Excerpt from The Deep Sky: An Introduction
The nine stars in STAR 29 form a nearly perfect, albeit sideways, number 7, leading to the group's nickname of "Lucky 7." The two brightest stars in the pattern are 5th-magnitude 1 and 2 Cassiopeiae, with the latter marking the bend in the 7.
Eta Cassiopeiae can be seen with the unaided eye as a 4th-magnitude star a third of the way from Schedar (Alpha Cassiopeiae) to Gamma Cassiopeiae in Cassiopeia's "W" formation.
The secondary star, Iota Cassiopeiae B, is the closer of the two faint companion stars and may be found only a couple of arc seconds to the primary's west.

One of the oldest of the star patterns we recognize, it was recognized by the ancient Greeks.
Observers who face north while looking up at Cassiopeia will see the star called "Caph," meaning the palm of a hand, on the left end of Cassiopeia’s upside-down "W." "The star’s name comes from a star picture envisioned by the Arabic peoples that is very different from the Greek conception of the constellation," Teske explained.
Alpha Cassiopeiae is located next to Caph, at the left bottom of the "W." It is also called Schedar, Arabic for "breast." Gamma, located at the middle of the "W," has no Arabic name.

The giant star, known as Rho Cassiopeiae, was first observed shedding an equivalent mass of material three years ago by the Isaac Newton Group of Telescopes - more than astronomers have ever witnessed in a single stellar eruption.
Cassiopeia is the big W (or M) in the northern sky.
