Top Astronomy Events in September 2025
From a complete lunar eclipse to Saturn, which shines brightly all night, there are top astronomy events marked down on the September calendar.
Saturn will host shows for professional astromers and backyard astromers, making it the brightest and closest to Earth all year round.
According to NASA, Saturn will be in the opposite direction on Sunday, September 21st.
In the morning sky, Venus and Jupiter also appear in the eastern part, but Saturn “will brighten in the sky” and the agency states in the video, “What’s Up: Tips from September 2025 NASA.”
According to NASA, the planet is very bright so the Stargazers can see it with the naked eye.
There are things you need to know about the planet and how you can see it.
When will Saturn oppose it?
According to NASA, Saturn will be opposed on Sunday, September 21st. This is when it’s the biggest and brightest of the year.
It will be displayed during September.
What stage is the moon at?
There is a new moon on Sunday. Therefore, according to NASA, the light of the moon does not interfere with the Stargazer’s ability to see planets at night.
Where is Saturn?
At night, Saturn is located in the eastern sky in the evening, but as you approach the early morning, you will move into the western sky.
Do I need equipment to see Saturn?
No, according to NASA, no equipment is required to see the planet. Although it can be seen with the naked eye, a small telescope can help bring Stargazers to a better view.
No equipment is required, but you can use Stargazing apps like Stellarium and Sky Safari to help you find planets in the night sky.
If you are planning on stargizing outdoors, pack a mosquito repellent and check the weather forecast in advance to make sure the sky is clear.
Saturn appears on the same day as a partial solar eclipse
The solar eclipse that will occur on Sunday, September 21st is invisible in the US but is seen in Australia, the Antarctic, the Pacific and Atlantic Oceans.
This is the second solar eclipse that will occur in September. The first was a complete lunar eclipse that occurred from September 7th to September 8th, but the lunar eclipse was also not visible in the United States.
Fall equinox is the day after a partial solar eclipse
Fall equinox will occur on Monday, September 22nd, according to NASA, the day after the solar eclipse is held.
equinox occurs once in March, once in September, once in equal lengths of day and night, twice a year.
“Equinox marks the exact moment when the center of the Sun crosses the equator plane of our planet,” NASA said on its website. “On the Equator Day, the Equator Observers will directly imaginate the Sun at noon.”
