... The spring constellation most prominent is Leo, the Lion. Leo really does resemble the outline of a lion. His front part is formed by the hook of stars extending north from the bright star Regulus in his forefoot. This hook of stars- usually called the Sickle- represents Leos chest, mane and head. ...

Astronomical spectroscopy
Astronomical spectroscopy is the study of astronomy using the techniques of spectroscopy to measure the spectrum of electromagnetic radiation, including visible light, which radiates from stars and other hot celestial objects. Spectroscopy can be used to derive many properties of distant stars and galaxies, such as their chemical composition, temperature, density, mass, distance, luminosity, and relative motion using Doppler shift measurements.
