Moon and Venus
Look for the Moon before sunrise tomorrow, with Venus, the “morning star,” to its lower left. Despite its moniker, Venus is a planet, not a star. In fact, it’s our closest planetary neighbor, passing as close as 27 million miles away.
Sky Test
The Big Dipper is high in the north as night falls, standing upside down. If you line up the two stars at the outer edge of the bowl and follow that line to the lower right, the first bright star you come to is Polaris, the North Star.
Vega Rising
Vega, one of the harbingers of summer, peeks above the northeastern horizon by around 9 p.m. Vega is one of the brightest stars in the night sky, and one of our closest stellar neighbors, at a distance of about 25 light-years.
Beta Ceti
Cetus, the whale or sea monster, is in the south and southwest at nightfall. Its brightest star, Beta Ceti, is the second-brightest star in a wide swath of sky. It’s outshined only by Fomalhaut, which is quite low at that hour.
Camelopardalis
Camelopardalis, the giraffe, is one of the largest constellations, covering a big wedge of the northern sky. But it isn’t very bold. All of its stars are so faint that you need to get away from city lights to see them.
Moon and Planets
The Moon and two bright planets form a beautiful triangle at dawn tomorrow. Brilliant Jupiter stands to the right of the Moon, with fainter orange Mars close below them.
Vanishing Venus
Venus will pass behind the Sun today, so it is lost from view in the Sun’s glare. It will return to view next month, when it will shine as the brilliant Evening Star.
Last-Quarter Moon
The Moon is at last quarter today at 4:25 p.m. CST. Sunlight will illuminate half of the lunar hemisphere that faces Earth. The illuminated fraction will continue growing smaller until the Moon is new, on January 16.
Taurus
Taurus, the bull, passes high overhead this evening. Its brightest stars form a long, thin wedge, with its brightest star, orange Aldebaran, at its southeastern corner. Taurus is at its highest around 9 p.m.
Orion’s Belt
Orion is in the eastern sky at nightfall. Its three-star belt points straight up from the horizon, with Orion’s other bright stars arrayed to its left and right. From top to bottom, the stars of the belt are Mintaka, Alnilam, and Alnitak.
