It is easily found, for the pointers of the Great Bear point southerly to its brightest star, distant about 45 degrees from the southernmost of them. Four stars in the body of Leo form a characteristic trapezium, and those about the neck and mane make a sickle. It is the fifth sign of the zodiac, its symbol as such being ♌, showing the lion's mane. See cut in next column.

Sometimes, identifications are even possible in the absence of laboratory data, as demonstrated recently by the detection of C5N− in the CSE of CW Leo .
Spectroscopic parameters for silacyclopropynylidene, SiC2, from extensive astronomical observations toward CW Leo (IRC +10216) with the Herschel satellite
However, SiC2 features are particularly strong toward CW Leo, which, to a large extent, is due to its proximity to our Solar system.
Spectroscopic parameters for silacyclopropynylidene, SiC2, from extensive astronomical observations toward CW Leo (IRC +10216) with the Herschel satellite
CW Leo has been studied extensively, and many molecular species, such as CN− and FeCN , have been detected toward its CSE exclusively or for the first time, including many Si-contain ing ones, such as SiCN and SiNC .
Spectroscopic parameters for silacyclopropynylidene, SiC2, from extensive astronomical observations toward CW Leo (IRC +10216) with the Herschel satellite
The isoelectronic molecules CN− (Gottlieb et al. 2007) and C3N− (Thaddeus et al. 2008) were found in the lab as well as in the circumstellar envelope of CW Leo.

For instance, several metal containing molecules have been detected first in the envelope of CW Leo, but in recent years MgNC, NaCN, and NaCl have been detected also in the envelopes of other AGB stars, the latter even in those of O-rich AGB stars such as IK Tau and VY CMa.
