Crescent moon to join pairing of planets

By Brian Lada,

Memorial Day weekend marks the unofficial start of summer, and the nights leading up to the holiday weekend will offer stargazers the opportunity to witness several celestial sights.

The planetary duo of Venus and Mars will be visible in the western sky every cloud-free evening into July, with Venus outshining every star in the sky. At first glance, the Red Planet may blend in with nearby stars, but its nickname will help onlookers spot the planet as it will glow slightly orange or red in color above and to the left of Venus.


Two nights in May are the best times to catch a glimpse of the planets as the duo will briefly turn into a trio as another object joins the astronomical display.

The crescent moon will align with Mars and Venus on Monday evening, appearing below the two planets leading up to the main event.

On Tuesday, the moon will glow between Venus and Mars, a gathering easily spotted in the western sky without a telescope.

An encore is on tap on Wednesday, as the moon shifts toward Mars, glowing directly above the Red Planet. While no telescope is needed, it will be a good night to zoom in on the objects as they will be in the same field of view even when looking through a telescope.


That won't be the only noteworthy sight worth gazing up at the night sky to take in through the end of the month.

When it's visible, the ISS is often one of the brightest objects in the sky after the sun and moon. Unlike airplanes with blinking lights, the ISS appears as a solid bright ball of light as it makes its way across the sky.

Each night, the ISS will appear at different times, and the times will vary from city to city, so it is important to check what time it will be visible from your area.

While it will be visible every night of the week, the space station's brightest passes over the United States will occur late in the week and through Memorial Day weekend.
