Today:
Stretched through the east and southeast near 10 o’clock, the brilliant stars Arcturus, two-thirds of the way up in the southeast, and Vega, well to its lower left, and one third of the way above the eastern horizon, help you to locate a faint semi-circle of stars between them, the Northern Crown, closer to Arcturus.
Monday:
Very high in the southeast on the next clear evening, as darkness becomes complete after 10 o’clock, a bright, pale orange beacon can easily be found, the red-giant star Arcturus. This “red” giant shines brighter and hotter than most, making its color more yellow-ish orange. Arcturus is the brightest star we see through the Summer and early Fall.
Tuesday:
On this date in 1910, the Earth passed through the tail of Halley’s Comet, an event that spawned any number of reactions, from taking “Comet Pills” to ward off the noxious vapors, to predictions of the end of the world. The dangers were greatly exaggerated, with no measurable effects.
