defined in 1756 by French astronomer Nicolas Louis de Lacaille. Its name
is Latin for compass, a tool that draws circles. Its brightest star is
the slightly variable Alpha Circini, the brightest rapidly oscillating
Ap star in the night sky, with an apparent magnitude of 3.19. AX Circini
is a Cepheid variable visible with the unaided eye, and BX Circini is a
faint star thought to have been formed from two merged white dwarfs. The
sun-like star HD 134060 has two small planets, and another, HD 129445,
has a Jupiter-like planet. Supernova SN 185 appeared in Circinus in
185 AD and was recorded by Chinese observers. Two novae were observed
in the 20th century. The Milky Way runs through the constellation,
featuring prominent objects such as the open cluster NGC 5823 and the
planetary nebula NGC 5315 (pictured). The Circinus Galaxy, discovered in
1977, is the closest Seyfert galaxy to the Milky Way. The Alpha
Circinids meteor showers, discovered the same year, radiate from this
constellation.

Wikiquote quote of the day:
One of life's best coping mechanisms is to know the difference
between an inconvenience and a problem. If you break your neck, if you
have nothing to eat, if your house is on fire, then you've got a
problem. Everything else is an inconvenience. Life is inconvenient. Life
is lumpy. A lump in the oatmeal, a lump in the throat and a lump in the
breast are not the same kind of lump. One needs to learn the difference.
