1Sky watchers around the world were treated this month to two full moons, a supermoon and a blue moon.
2The American space agency NASA explains a supermoon happens when the moon's orbit brings it closer than usual to Earth at the same time that the moon appears full from Earth.
3The first supermoon of 2023 was in July.
4The fourth and last one will be in September.
5The last time two supermoons appeared in the sky in the same month was in 2018, The Associated Press reports.
6The next time a blue supermoon is set to arrive is 2037.
7The first supermoon arrived on the first day of August, while the blue moon was seen beginning August 30.
8NASA noted that when the blue moon arrived, the planet Saturn was just a few days from its closest and brightest appearance of the year from Earth.
9Saturn appeared as a bright "star" to the upper right of the blue moon.
10Italian astronomer Gianluca Masi, creator of the Virtual Telescope Project, held an online watch event as the blue supermoon was setting below the skyline of Rome.
11But he advised that, as long as the weather was good, world observers looking to the sky would not need any special equipment to see the moons.
12"Warm summer nights are the ideal time to watch the full moon rise in the eastern sky within minutes of sunset," said retired NASA astrophysicist and moon expert Fred Espenak.
13Full moons happen at the exact moment when the moon is opposite the sun, NASA says.
14Astronomers say a supermoon can appear about 14 percent larger and a bit brighter than other moons.
15The Old Farmer's Almanac notes that the August full moon is known as the sturgeon moon.
16This is because of a traditionally large increase in fish in the American Great Lakes area during the month of August.
17Although it is called a blue moon, it does not appear blue in color.
18Instead, the name means it is the second full moon to happen within one month or the fourth to take place in a season.
19NASA says the moon takes 27.3 days to orbit Earth, but it takes 29.5 days to complete a full moon cycle.
20This is what makes it possible to see one full moon at the start of the month and another one right at the end.
21Astronomers say, however, that the moon can look blue under the right conditions.
22For example, this can happen as a result of smoke or dust particles in the atmosphere.
23While the blue supermoon brings the possibility for watching and taking beautiful pictures, its stronger gravitational pull also can influence higher tides.
24Weather experts advise people living in areas near shorelines to be aware of this, especially during storm activity.
25There are other kinds of moons that appear at different times.
26NASA says a blood moon happens during a total lunar eclipse.
27This event is when Earth lines up between the moon and the sun, hiding the moon from sunlight.
28In addition, the term blood moon can also be used to describe a moon that appears reddish because of dust, smoke or haze particles in the sky.
29A harvest moon is a full, bright moon that appears "closest to the start of autumn," NASA explains.
30This name dates from the time before electricity, when farmers depended on the moon's light to harvest their crops late into the night.
31The moon's light was especially important during fall when harvests are the largest.
