Sky & Telescope: moonless Perseids Aug. 13

Sky & Telescope said on August 5 that this year’s Perseid meteor shower should arrive under unusually favorable viewing conditions, with a new moon leaving the peak night dark from dusk to dawn. NASA said the shower has been active since early July and will continue through the end of August, with the strongest activity expected on the night of August 12 into the early morning of August 13. The Perseids are one of the year’s brightest and most widely watched meteor showers, and Earth sees them each year as it passes through debris left by Comet 109P/Swift-Tuttle. ### Why are astronomers saying 2026 is a particularly good Perseid year? Sky & Telescope said the key advantage in 2026 is the moon. Bob King wrote that a new moon will leave observers with “moonless skies the whole night long,” removing a common source of glare that can wash out fainter meteors. NASA’s August skywatching guide also said the new moon arrives on August 12, making skies “ideally dark” for the peak. (skyandtelescope.org) WTHR reported that the setup could make this the best Perseid viewing in 19 years because there will be no moonlight interfering during the peak window. That assessment is from a local outlet rather than NASA or Sky & Telescope, but it reflects the same basic forecast: darker skies should improve visibility, especially away from city lights. (skyandtelescope.org) ### When should people actually go outside? NASA said the shower reaches its peak on the night of August 12 into the early morning of August 13. Sky & Telescope’s coverage, published August 5, pointed to the same overnight window, and WTHR said the best viewing is forecast for the early morning hours of Thursday, August 13, 2026. (wthr.com) Timeanddate.com’s visibility guide says meteor watching usually improves after midnight as the radiant climbs higher, and several 2026 guides point to roughly 1 a.m. to 4 a.m. local time as the strongest period for U.S. viewers. NASA’s guidance does not require viewers to locate the radiant precisely; meteors can appear across the sky. (nasa.gov) ### How many meteors are expected, and why do estimates vary? Aspen Times reported that peak viewing could bring up to 70 shooting stars per hour. Other outlets and astronomy sites have published higher figures, but NASA’s current public guidance emphasizes the Perseids’ brightness and popularity rather than a single nationwide hourly count. Actual rates depend on cloud cover, local light pollution, and whether the observer has allowed time for their eyes to adjust to darkness. (timeanddate.com) Sky & Telescope’s framing is more practical than numerical: dark skies increase the odds of seeing more meteors, including fainter ones that would be lost in moonlight or urban glow. For casual viewers, that may matter more than the headline estimate. ### What causes the Perseids in the first place? NASA said the Perseids happen every year when Earth passes through a stream of debris left behind by Comet Swift-Tuttle. (nasa.gov) WIRED’s August astronomy calendar identified the parent body more formally as Comet 109P/Swift-Tuttle and said the particles burn up in Earth’s atmosphere as bright meteors. (skyandtelescope.org) The shower appears to radiate from the constellation Perseus, which is where it gets its name. That does not mean viewers need to stare directly at Perseus; meteor streaks can show up in many parts of the sky. ### What is the simplest way to watch without equipment? NASA said no telescope is needed for the Perseids. (science.nasa.gov) The agency recommends finding a safe location away from bright city lights, allowing eyes time to adapt to the dark, and looking up for an extended period rather than expecting immediate activity. Timeanddate.com similarly says viewers need only a clear sky and patience. (timeanddate.com) Washingtonian, in advice for the Washington area, pointed readers toward darker skies near Delaplane, Virginia. The same principle applies elsewhere in the United States: darker, less developed locations generally improve the view. ### What happens after the peak night? NASA said the Perseids will remain active through the end of August even after the August 12–13 peak passes. (nasa.gov) The agency also said it will livestream a meteor watch party starting at midnight Eastern time on August 13 on YouTube, with meteor experts, live sky views and viewer questions.
