Moon Phases, Planets, and Meteor Showers July 2020

what's in the sky july astronomy events 2020 - 1

July 4 - Penumbral Lunar Eclipse

A penumbral lunar eclipse happens when the Moon passes through the Earth's partial shadow, known as the penumbra. The Moon will darken slightly but not completely. When correctly observed, the eclipse will be visible throughout most of North America, South America, the eastern Pacific Ocean, the western Atlantic Ocean, and extreme western Africa.

July 4 - Full Moon

Some early Native American tribes knew this full Moon as the Buck Moon because the male buck deer would begin to grow their new antlers at this time of year. It is also referred to as the Thunder Moon and the Hay Moon.

July 14 - Jupiter at Opposition

The giant planet will be at its closest approach to Earth! It will be visible all night long. This is the best time to view and photograph Jupiter and its moons. A medium-sized telescope should be able to show you some of the details in Jupiter's cloud bands. A good pair of binoculars should allow you to see Jupiter's four largest moons, appearing as bright dots on either side of the planet.

July 20 - New Moon

A New Moon is the best time of the month to observe faint objects such as galaxies and star clusters because there is no moonlight to interfere.

July 20 - Saturn at Opposition

The ringed planet will be at its closest approach to Earth, and its face will be fully illuminated by the Sun. This is the best time to view and photograph Saturn and its moons. A small telescope will be enough to see Saturn's rings, but a medium-sized or larger telescope will reveal a few of its brightest moons!

July 22 - Mercury at Greatest Western Elongation

The planet Mercury will reach its greatest western elongation. This is the best time to view Mercury since it will be at its highest point above the horizon in the morning sky. Look for the planet low in the eastern sky just before sunrise.

July 28, 29 - Delta Aquarids Meteor Shower

The Delta Aquarids is an average shower that can produce up to 20 meteors per hour at its peak. The shower runs annually from July 12 to August 23. This year it peaks on the night of the 28th and morning of the 29th. The best viewing will be from a dark location after midnight.

    That you offer this is nice. I’m a supporter. I really like your company. But you must do better. Too many errors. “This lunar eclipse will be visible from….”. No, a partial penumbral lunar eclipse is not visible at all. No observer will detect any change on the full moon that night. “Early Native American tribes knew this as the Buck Moon.” No, only the Algonquin did. And even many of them called It the Thunder Moon. A dozen other tribes had various other names for this full moon. “A medium or larger telescope will allow you to see Saturns rings…”. No, any small telescope will do the job, at a mere 30x or higher. Anyway, you must do better if you’re speaking to astronomers. I’ll help, if you ask.
