Andromeda and Pegasus are rising in the north-east, while Cepheus lies between Cassiopeia and Cygnus. Looking southwards in autumn, the four stars which make up the distinctive "square" of Pegasus are high in the sky with Andromeda above and to the left. Eastwards are the faint constellations of Aries (the Ram), Pisces (the Fishes) and Cetus (the Whale). Below Pegasus and due south is Aquarius, and lower down is summer the bright red star Fomalhaut in Piscis Austrinis. The triangle is still high in the south-west, while between Aquila and Cygnus and a little to the east lies the tiny constellation Delphinus.

Stars give out all kinds of radiation, but with increasing temperature they emit more and more short-wave radiation. Since blue light has shorter wavelength than red, the hotter they are the bluer they seem. 42 1 INFRA-RED tT DISTANCE AND SIZE basic technique for measuring stellar The method of trigonometrical parallax. In distance is the principle the method is simple: if we observe the position of a nearby star (X) against the background of distant stars when the earth is at E, and again six months later when the earth is on the opposite side of the sun (S) at point F, then because the two points E and F are separated by the diameter of the earth's orbit, the star will appear to be displaced in position.
