The Milky Way is making its first major appearance of the year in the Northern Hemisphere, and it’s set to be visible across the United States this May. However, not everyone will have the same opportunity to catch a glimpse. According to a 2023 study published in Science, light pollution has drastically increased, with the sky’s brightness rising by up to 10% annually from 2011 to 2023. This means that one-third of humanity, and nearly 80% of Americans, are now unable to see the Milky Way due to the encroachment of artificial light. If you’re one of the lucky stargazers situated in an area with minimal light pollution, this May will offer some of the best opportunities to see the Milky Way stretching across the night sky.
To maximize your chances, it’s essential to find a location far from artificial lights. Dark Sky Places or regions on a light pollution map marked as dark zones are ideal for the best stargazing experience. The period between May 20 and May 30, coinciding with the last quarter moon and new moon phases, will provide optimal viewing conditions. This is the perfect opportunity to witness the galaxy in its brightest form as it climbs higher in the sky.
The Science Behind the Milky Way’s Appearance This May
In the Northern Hemisphere, May is a particularly favorable month for observing the Milky Way, as it rises higher and earlier in the sky. Skywatchers in mid-latitudes, including much of the United States, will have a prime opportunity to catch a stunning view. According to the popular Milky Way photography site Capture the Atlas, the “Milky Way season” spans from February to October, but it peaks during the late spring to early summer months, when it becomes most visible. The core of the Milky Way becomes especially prominent after midnight, between 12:00 a.m. and 5:00 a.m. local time.
For a reliable guide on when to view the Milky Way, tracking the appearance of the Summer Triangle is key. This asterism—composed of the bright stars Deneb (Cygnus), Vega (Lyra), and Altair (Aquila)—forms an easy-to-recognize shape in the sky. As the Summer Triangle rises in the eastern sky, it marks the perfect time to begin searching for the Milky Way. Between May 20 and May 30, the Summer Triangle will be visible around midnight, moving to a higher position by 3 a.m. local time. The Milky Way’s core will follow closely behind, making this an ideal time to catch a breathtaking view.
Best Locations to View the Milky Way in the U.S.
If you’re planning to see the Milky Way this May, finding the right location is crucial. Light pollution is the biggest obstacle for stargazers, and even a small amount of artificial light can obscure the view. To escape this, many enthusiasts recommend heading to a Dark Sky Place, a location specifically designated for its low levels of light pollution. There are over 130 Dark Sky Places in the United States, including well-known spots such as Grand Canyon National Park, Joshua Tree National Park, and Big Bend National Park. These areas offer some of the best views of the Milky Way and are frequently visited by photographers and astronomers looking to capture the galaxy in all its glory.
Another way to find the best stargazing spots is by checking a light pollution map, which helps identify dark areas for clear sky views. For example, places like Bryce Canyon National Park in Utah and Great Sand Dunes National Park in Colorado are known for their exceptional visibility. If you live in a more urban area, consider traveling to a nearby dark zone for the best chance to experience the Milky Way’s splendor.
When to See the Milky Way: Key Dates and Times
The best time to see the Milky Way varies depending on your location, the phase of the moon, and other environmental factors. In May 2025, the period between May 20 and May 30 is ideal for Milky Way viewing, as the sky will be dark due to the new moon phase. This is when the moon’s light will not interfere with the visibility of the galaxy’s bright core. According to Capture the Atlas, stargazers can expect the Milky Way to become most visible after midnight, with the galaxy rising higher into the sky as the Summer Triangle comes into view.
Although the Milky Way can be seen for much of the year, May offers one of the best opportunities before the sky brightens during the summer months. This is especially true for those living at mid-latitudes, where the galaxy’s core rises earlier in the evening. By June and July, the sky will remain brighter for longer periods of time due to the summer solstice, making May a prime time to see the Milky Way before it climbs even higher and appears more spectacular later in the summer.
