Spectacular Venus–Jupiter “Cosmic Kiss” Dazzles Early Morning Skies (Don’t Miss It!)

The Venus–Jupiter conjunction occurs August 11–13, 2025, with its closest approach on August 12 at about 0.86° apart. Venus will shine around magnitude -4.0 and Jupiter around -1.8 to -2 during the pairing. The pair sits about 35° from the Sun, enabling viewing in a dark dawn sky. Observers should view about 45 minutes to an hour before sunrise, when the planets are 5–10° above the horizon and will rise to 15–20° as dawn progresses.

Jupiter Unveiled: Surprising Secrets of the Giant Planet and Its 95 Moons

Jupiter is the Solar System’s largest planet, about 318 Earth masses, with a rotation period of roughly 9.9 hours per day. It is composed mainly of hydrogen and helium, with a metallic hydrogen layer that powers a strong magnetic field via a dynamo. The Great Red Spot is a storm at least 300–350 years old, about twice Earth’s diameter, whose roots extend roughly 300 miles (500 km) into the atmosphere. Jupiter’s magnetosphere extends 1–3 million kilometers toward the Sun and a tail over 600 million kilometers long, with a field 14–54 times stronger than Earth’s and new radiation zones near
