High in the southeast this evening, starting near 7 o’clock, a waxing Gibbous Moon shines just below a pair of stars, quite fittingly known as the Twins, or Gemini. As one of the zodiac constellations, the Moon tracks through these stars every 27 days and 8 hours, which brings us a similar display at the end of this month.
As the star Arcturus climbs to one third of the way above the eastern horizon 11 o’clock this evening, look for another brilliant star to return to the skies, the bluish-white Vega, just rising in the northeast. Vega appears on any clear night of the year, but shifts into evening skies in the Spring.
Very high in the west near 8 o’clock sparkles the brilliant star Capella, the fourth brightest star that we can see. What we can’t see is that it is actually a pair of bright, giant stars, each more than twice as massive as the Sun. They orbit each other once every 104 days, no farther apart than the Sun and Venus.
