Today:
With the Summer Triangle almost overhead, look at its lowest star Altair, and then to the left of Altair. A faint, compact collection of stars may catch your eyes, the constellation Delphinus, the Dolphin. It appears like a comma, but perhaps you can imagine a dolphin leaping from right to left, out of the celestial waters.
Saturday:
Looking high in the east at 10 PM revels Cygnus the Swan, its tail marked by the bright star Deneb, which is also a member of the Summer Triangle. Cygnus will move almost overhead by midnight when, just to its south, you can see Aquila the Eagle, and its bright star, Altair, which is another point on the Summer Triangle.
Sunday:
While the Moon approaches Full, though rather low in the southeast, look to the zenith – the top of the sky – where a bright star shines with a steely-blue light. Vega ranks as the 4th brightest star in the heavens, twice as massive as our Sun, emitting 37 times more light, while converting hydrogen to helium ten times faster than the Sun.
