Shaula is an epic variable star. It lies about 571.2 light-years from Earth, sits in the constellation Sco, shines at apparent magnitude 1.62 and has spectral type B1.5IV+....
Its spectrum reads B1.5IV+... — a blue-white B-type star, with a surface tens of thousands of degrees hot and a life measured in tens of millions of years.
Look for Shaula in the constellation Sco. At apparent magnitude 1.62, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, Shaula is best seen from a dark site away from city lights, and when it is above the horizon depends on your latitude and the time of year. The visibility panel above works out tonight's viewing window for your saved location.
Shaula scores 57 points on Spacedle's rarity scale, which places it in the epic tier. Another 21 points would lift it into a rarer tier.
That score comes from 10 science badges — Variable star, Naked-eye visible, Has a proper name, On the zodiac, Hot blue B-type star, Subgiant (leaving the main sequence), Blue-white star and Intrinsically luminous (Mv < −2) — each earned for a real, measurable property of the object. Rarity on Spacedle is never random: the more remarkable an object's astrophysics, the more badges it collects, the higher it scores, and the rarer it ranks.
