Spectacular June sky events: Venus–Jupiter conjunction and rare lunar occultation

Astronomers explain that this event is called a planetary conjunction. Although the planets are millions of miles apart in space, they appear close together from Earth’s point of view because they lie along a similar line in the sky, Science Daily reports.

From June 11 to June 15, Mercury will also join Venus and Jupiter low in the western sky, forming a small planetary grouping. Venus will be the brightest and easiest to see, Jupiter will shine nearby, while Mercury will appear much lower near the horizon and may be harder to spot.

Another highlight comes on June 17, when the Moon will pass directly in front of Venus for observers in certain locations. This event is known as a lunar occultation. In those regions, Venus will briefly disappear behind the Moon before reappearing later. The occultation will be visible from parts of the United States, Canada, Brazil, and Venezuela. Even outside the narrow viewing path, many observers will see the Moon and Venus unusually close together.

In some places, the event will occur during daylight hours. Astronomers warn that anyone observing should be careful and never point binoculars, telescopes, or cameras near the Sun without proper solar protection, as this can cause serious eye damage.

June also marks the summer solstice, the official start of astronomical summer in the Northern Hemisphere. In Pacific Time, it occurs on June 21 at 1:24 a.m., bringing the longest days and shortest nights of the year.

As the month continues, classic summer stargazing targets become more visible. One of the most recognizable patterns is the Summer Triangle, formed by the bright stars Vega, Altair, and Deneb.

Within this region, several well-known deep-sky objects can be observed with telescopes or long-exposure photography, including the Dumbbell Nebula, Ring Nebula, North America Nebula, and Veil Nebula. The Dumbbell Nebula (Messier 27) is especially significant as the first planetary nebula ever discovered.

These objects are usually too faint to see with the naked eye, but reveal detailed structures such as glowing gas clouds and dying stars when viewed through optical equipment.

Overall, June offers a combination of bright planetary alignments, a rare lunar occultation, the summer solstice, and rich deep-sky objects, making it an excellent month for stargazing.
