Astronomical events of June 2025

June arrives loaded with celestial magic. Whether you're a lover of the skies or simply enjoy gazing at the heavens on warm nights, this month offers an astronomical calendar packed with events worth observing. From the iconic Strawberry Moon to meteor showers and planetary alignments, June 2025 is an open invitation to reconnect with the cosmos.

June 21: The Sun celebrates its longest day

The summer solstice in the Northern Hemisphere will occur on June 21 at 4:42 a.m. (UTC), marking the longest day of the year. This phenomenon occurs when the Earth's axis tilts most toward the Sun, providing more hours of daylight and intense solar energy to the northern part of the planet.

Beyond its astronomical significance, the solstice has been celebrated around the world since ancient times, from Stonehenge to modern festivals like Inti Raymi. It's an excellent time to observe the sun reaching its highest point in the sky at noon.

June 11: Strawberry Moon, low and bright

The June full moon, traditionally known as the Strawberry Moon, will be visible on June 11. This name comes from Native American tribes, who associated it with the harvesting of wild strawberries.

This year, the Moon will offer a special spectacle: in the Northern Hemisphere, it will appear unusually low on the horizon, a configuration that will not be repeated until 2043. Meanwhile, in the Southern Hemisphere, the Moon will be higher than usual, ideal for observation with telescopes or even a simple view.

Moon phases of June

• First Quarter Moon: June 3
• Full Moon: June 11
• Last Quarter: June 18
• New Moon: June 25

These phases are key for both lunar observation and those seeking dark skies during meteor showers.

Meteor showers: the sky becomes a highway

June becomes an active stage for shooting stars. Several meteor showers will occur, notable for their frequency and variety. While some are discreet, others can surprise with bright peaks just before dawn.

• June 4: Omega Scorpids and Sagittarids — slow-moving, bright meteors, ideal for viewing from the Southern Hemisphere.
• June 7: Arietids (up to 66 meteors per hour) and Zeta Perseids (20 meteors per hour), visible in the early morning.
• June 8-10: Multiple activity with Iota Scorpidae, Libridae, Tau Herculidae and Theta Ophiuchidae.
• June 15-29: June Lyrids, Achilles, Corvids, Beta Taurids, and more, closing out the month with variety and surprises.

Tip: To enjoy the show to the fullest, find a dark spot away from artificial lights, and be patient: meteors appear in bursts.

Planetary encounters and notable occultations

In addition to the Moon and meteors, June offers several key times to observe alignments and occultations:

• June 10: The Moon briefly occults Antares, the red star in the heart of Scorpio.
• June 12: Venus reaches its greatest western elongation, visible as a bright "morning star."
• June 17: Mars approaches Regulus, the alpha star of Leo.
• June 23: The Moon reaches its perigee (closest point to Earth) and occults Alcyone, the main star of the Pleiades.
• June 24: Conjunction between the Sun and Jupiter, and the Moon crosses near Elnath (Taurus).
• June 30: We bid farewell to the month with a close encounter between the Moon and Mars, separated by just 0.2°.

Conclusion: June is for looking at the sky

With so much astronomical activity, June 2025 is the perfect month to pull out your telescope (or just lie down on a blanket) and gaze upward. Whether you're keeping track of the moon phases, hunting for shooting stars, or marveling at a planetary conjunction, this month reminds us that the sky is full of stories waiting to be discovered.
