Happy New Year! Though you likely won’t be able to tell the difference, Earth is at its closest to the Sun for the year this month, January 2020. Perihelion, the point in Earth’s annual orbit where it’s closest to the Sun, occurs each year in early January. This year, perihelion occurs at 1:48 a.m. Chicago time on […]

The brightest planet, Venus, begins a run of many weeks’ worth of spectacular viewing in the evening skies this month, December 2019. Venus starts off the month very low in the southwest after sunset, setting only about 90 […]

Because Daylight Saving Time ended on the 3rd, the Sun now sets before 5:00 p.m. local time. It won’t be setting after 5:00 p.m. until late January. Shortly […]

It was 50 years ago on July 20 when humans first set foot on Earth’s natural satellite. It’s a big month for the Moon astronomically as well. This […]
Though the Sun sets later and later each evening this month, there are still plenty of fine night-sky sights in May 2019. After sunset, look about 25 degrees above the west-northwest horizon to see the planet Mars. It’s dimmer than first magnitude in brightness, but it’s still bright enough—and colorful enough—to be easily spotted. The […]
Though Spring has begun in the Northern Hemisphere, some of the night sky’s brightest stars—usually associated with wintertime—can still be seen this month, April 2019. Look to the southwest during evening twilight, to see a rhombus-shaped pattern of bright stars—like a long, thin, horizontally-stretched-out square in the sky. The top point of the rhombus is […]
