Meteor Showers to Peak This Week Amid Favorable Viewing Conditions

Stargazers have a promising opportunity to observe meteor showers this week, as the Southern Delta Aquariids and Alpha Capricornids are set to peak on the night of July 29 into July 30. Unlike the upcoming Perseid meteor shower in mid-August, which will coincide with a bright moon, this week's showers benefit from a moon that is only about 25% full, improving visibility.

Nick Moskovitz, a planetary astronomer at Lowell Observatory, explained that the glare of a nearly full moon in August will make the Perseids less compelling this year. In contrast, the current conditions may allow viewers to see up to 20 to 30 meteors per hour from the combined showers. Meteor showers occur when Earth passes through debris left by comets or asteroids, producing bright streaks as tiny particles burn up in the atmosphere.

Hunter Miller, an astronomy educator at the Adler Planetarium, noted that these shooting stars are often caused by debris as small as dust or grains of sand. For the best experience, Moskovitz advises watching after midnight and before dawn, away from artificial lights, and allowing 15 to 30 minutes for eyes to adjust to the dark. He also recommends facing the southern sky for the Southern Delta Aquariids, while the Alpha Capricornids, though less frequent, can produce slow, bright fireballs.

If weather conditions are unfavorable on the peak night, meteor activity can still be observed in the days surrounding the peak. Miller emphasized the abundance of meteor showers during this period and encouraged seeking out dark skies. Despite the bright moon in August, Miller said the Perseids may still offer chances to see bright meteors. Looking ahead, Moskovitz mentioned that 2026 is expected to bring an unusually strong Perseid outburst with a dark moon, potentially yielding hundreds of meteors per hour.
