Asterism of the month: The Teapot (in Sagittarius)


As seen from the northern hemisphere, Sagittarius's brighter stars form an easily recognizable asterism known as 'the Teapot'. The stars Kaus Media, ε Kaus Australis, Ascella, and Albaldah form the body of the pot; Kaus Boreali is the point of the lid; Alnasl is the tip of the spout; and Nunki and τ Sgr the handle. These same stars originally formed the bow and arrow of Sagittarius.

Marking the bottom of the teapot's "handle" (or the shoulder area of the archer, are the bright star (2.59 magnitude) Zeta Sagittarii (ζ Sgr), named Ascella, and the fainter Tau Sagittarii (τ Sgr).

To complete the teapot metaphor, under good conditions, a particularly dense area of the Milky Way can be seen rising in a north-westerly arc above the spout, like a puff of steam rising from a boiling kettle.

Around the teapot are some wonderful telescope targets including a number of Messier objects including the Triffid Nebula (M20). Have a look at our messier list or Messier Hunt gallery.


Trivia: Russell's teapot

Russell's teapot, sometimes called the celestial teapot or cosmic teapot, is an analogy, coined by the philosopher Bertrand Russell (1872–1970), to illustrate that the philosophic burden of proof lies upon a person making scientifically unfalsifiable claims, rather than shifting the burden of disproof to others. Russell specifically applied his analogy in the context of religion.[1] He wrote that if he were to assert, without offering proof, that a teapot orbits the Sun somewhere in space between the Earth and Mars, he could not expect anyone to believe him solely because his assertion could not be proven wrong.
