There’s plenty of planetary action to be enjoyed in August, according to NASA’s latest rundown of what to look out for in the sky this month.
Highlights include a morning meetup between Jupiter and Venus, a chance to see the Perseid meteor shower, and a glimpse into the destiny of our own sun.
Mars is also viewable this month, in fact, it’s the only planet that’s visible in the early evening sky in August. You’ll be able to spot it low in the west for about an hour after daylight starts to fade, though you’ll have to look hard, as the glow of its characteristic salmon-pink color is now only about 60% as bright as it was in May.
Later in the evening, at around 10 p.m., you’ll be able to spot Saturn, and as the month goes on it’ll appear a little earlier each evening. Look out for Saturn in the east after dark with the constellations Cassiopeia and Andromeda. The planet will appear to move toward the western part of the sky by dawn, so if you’re an early riser, it’s the perfect time to take a look.
“The real highlight of August is the close approach of Jupiter and Venus,” NASA says. “They shine brightly in the east before sunrise throughout the month.” The two planets appear far apart at the start of August, but as the days pass, they’ll move closer together. “They appear at their closest on the 11th and 12th — only about a degree apart. Their rendezvous happens against a backdrop of bright stars including Orion, Taurus, Gemini, and Sirius. A slim crescent moon joins the pair of planets after they separate again, on the mornings of the 19th and 20th,” NASA says.
The Perseids meteor shower is back again, and peaks overnight on August 12 and 13. But this year the moon is nearly full on the peak night, and so its brightness will impact the ability to see the meteors, except for the brightest ones. NASA says that while this is obviously disappointing, another meteor shower, the Geminids, will offer an excellent viewing opportunity — free of any moonlight — in December.
This month is also a wonderful chance to view the Dumbbell Nebula, also known as M27, which is a type known as a “planetary nebula.”
“A nebula is a giant cloud of gas and dust in space, and planetary nebulas are produced by stars like our sun when they become old and nuclear fusion ceases inside them,” NASA explains. “They blow off their outer layers, leaving behind a small, hot remnant called a white dwarf. The white dwarf produces lots of bright ultraviolet light that illuminates the nebula from the inside, as the expanding shell of gas absorbs the UV light and re-radiates it as visible light.”
Nicknamed for its dumbbell-like shape, the Dumbbell Nebula shows in the night sky as a small, faint patch of light about a quarter of the width of the full moon when viewing through binoculars or a small telescope. The diagram below gives you an idea of where to look — or consult your favorite astronomy app to find its precise location.
“Here’s hoping you get a chance to observe this glimpse into the future that awaits our sun about 5 billion years from now,” NASA says. “It’s part of a cycle that seeds the galaxy with the ingredients for new generations of stars and planets — perhaps even some not too different from our own.”
After 13 suborbital test flights and more than $15 billion in development costs, SpaceX's Starship has finally reached orbit. The 407-foot megarocket, the most powerful ever built, lifted off from Starbase, Texas, on Monday and delivered its first real payload on it's 14th attempt. The celebration came with an asterisk, though, since SpaceX had to cut the planned 10-hour mission to roughly three hours.

SpaceX is finally ready to give Starship its biggest test yet. The company says the massive rocket's 14th test flight is scheduled for September 22, when it will attempt to put the upper stage into Earth orbit for the first time. The launch is currently pending regulatory approval, with a 75-minute window opening at 7:15 a.m. CT.
Starship has 26 Starlink satellites to deliver
For decades, humanity has looked up at the Moon and wondered what it would be like to live on it. Think sprawling cities, factories, research centers, and permanent human settlements. Unfortunately, there is one fairly fundamental problem with that vision.
A new study published in Frontiers in Space Technologies argues that even the Moon's potentially enormous reserves of frozen water may be nowhere near enough to support city-sized populations sustainably. Researchers Martin Elvis and Jonathan McDowell estimate that the permanently shadowed regions near the lunar poles could contain roughly one billion tons of water. It sounds like an extraordinary amount until you put a million thirsty humans next to it.
