, appeared in the constellation in 1572 and disappeared in 1574. In this constellation is located Cassiopeia A, a discrete radio source emitting 21-cm radiation with great intensity. Cassiopeia reaches its highest point in the evening sky in November, but because of its location near the pole it is visible throughout the year to most northern observers.

Cassiopeia

(kass-ee-ŏ-pee -ă) A conspicuous constellation in the northern hemisphere, lying partly in the Milky Way. The five brightest stars form a W-shape, which includes Schedar (α), the blue-white visual binary Cih (γ), which is an irregular variable and an X-ray source, and the cream-colored Caph (β), all of 2nd magnitude. Eta, close to Schedar, is a 3rd-magnitude binary star. The area contains some fine open clusters (M52 [NGC 7654], M103 [NGC 581], NGC 457 and NGC 663) and globular clusters and the remnants of two recent supernovae – Tycho's star and the radio source Cassiopeia A. Abbrev.: Cas; genitive form: Cassiopeiae; approx. position: RA 1h, dec +60°; area: 598 sq deg.

Cassiopeia

 

a constellation of the northern sky. Its brightest stars ε, δ, γ, α, and β, which form a figure W, have brightnesses of 3.4, 2.7, 2.4, 2.2, and 2.3 visual stellar magnitudes, respectively. In 1572 a supernova flared up in the constellation. The most powerful known source of radio emission originates from the constellation, which is located in the Milky Way. The best conditions for observing it are from September to November. It is visible the year round everywhere in the USSR. It is named for Cassiopeia, in ancient Greek mythology the wife of the Ethiopian king Cepheus and the mother of Andromeda.
