I have to admit I have very recently learnt how to recognise Aries. In fact, for a city-dweller, Aries is a bit tough: it has only two stars brighter than magnitude 3 (Hamal and Sheratan). And, according to the first axiom of Euclid, two dots make a line. Nothing else! So, how can you tell in the sky one “line” from the other?

But there are a couple of things that help. For example, Taurus is quite easy to spot. If you trace a straight line from its brightest star (Aldebaran) and the Pleiades, you will find a faint constellation, Triangulum. Its stars are not very bright, but, since they make an isosceles triangle, you can recognise them. Then, you will easily find Aries under Triangulum.

After a bit of research, I have discovered some astronomers defined an unofficial constellation, Musca (the Fly). This constellation was made of three or four dim stars of Aries, half-way between the Pleiades and Triangulum. If you watch carefully you will be able to see even these tiny stars.
