The Delta Aquarid meteor shower is at its best this week. Its “shooting stars” appear to rain into Earth’s atmosphere from the constellation Aquarius. The meteors can appear in any direction, however, so it is best to scan the entire sky.

Last Week's Stargazing Tips
July 26: Delta Aquarid Meteors
July 25: Scutum
The constellation Scutum stands to the upper left of teapot-shaped Sagittarius as night falls. Under dark skies, you can see that it is enwrapped in the hazy veil of the Milky Way.
July 24: Scorpius Clusters
The big, beautiful star clusters M6 and M7 stand just above the stars that mark the scorpion’s stinger. M7 is the brighter of the two. Under dark skies, it looks like a small, fuzzy patch of light. Smaller M6 is to its upper right.
July 23: The Stinger
The celestial scorpion has a potent stinger. The two stars at the end of its tail, which mark the stinger, are bright, big, and heavy. And at least one of them is likely to suffer a sting of its own: it will explode as a supernova.
July 22: Mu Cephei
One of the largest stars in the galaxy is Mu Cephei, in Cepheus. It is visible in the northeast in the evening, halfway between Cygnus, the swan, and W-shaped Cassiopeia, the queen. It is roughly 1,500 times the Sun’s diameter.
July 21: Scorpius
The beautiful constellation Scorpius skitters low across the south on summer nights. It forms a distinctive hook shape, and its leading light is quite bright, so it’s easy to pick out. The bright planets Mars and Saturn stand just outside its borders.
July 20: Hercules
Hercules stands directly overhead this evening. Four moderately bright stars form a lopsided square that represents his body, while his head points southward. He is surrounded by several of the monsters he dispatched, including Hydra, the water snake.
