April 27: Moon, Mars, and Aldebaran

Aldebaran and Mars perch to the upper left and upper right of the Moon, respectively, as evening twilight fades. Aldebaran is the leading light of Taurus, while Mars is the fourth planet from the Sun.

April 28: More Moon, Mars, and Aldebaran

Aldebaran, the eye of the bull, is in good view early this evening. The star stands below the Moon as night falls, so it’s easy to spot. The fainter planet Mars stands to the right of Aldebaran.

April 29: The Solitary One

As night falls, the southern sky is a big blob of darkness, with only one modestly bright star in the whole region: Alphard, “the solitary one.” It is the brightest star of Hydra, the water snake, which stretches halfway across the southern sky.

April 30: The Most Beautiful

Boötes is in the east at nightfall, marked by its brightest star, yellow-orange Arcturus. The first noticeable star to the left of Arcturus is Izar. To the eye it looks like a single point of light, but a telescope reveals a colorful binary.

May 1: Beltane

Today is the date of Beltane, an ancient Celtic festival that was celebrated with bonfires. In Celtic culture, the date marked the beginning of summer, not the middle of spring as it is today. Some of Beltane’s traditions are preserved as May Day.

May 2: First-Quarter Moon

The Moon is at first quarter at 9:47 p.m. CDT tonight. At that moment, sunlight illuminates one-half of the lunar hemisphere that faces Earth. The Moon rises in early afternoon and stands high in the southwest at nightfall.

May 3: Moon and Regulus

Regulus is one of the brightest lights in the night sky. Seen with the eye alone, the lion’s heart is the 21st brightest star in the night. And the brilliant star is in great view tonight, standing just a whisker away from the Moon.
