Two Oppositions & Major Meteor Shower

Wow! A major annual meteor shower sandwiched between the oppositions of two major planets. If you enjoy skywatching, this is definitely the month to get outside on August evenings. And a telescope isn’t needed—just a clear night (and a lawn chair for the meteor shower).

Moon Day!

Well, it’s July and time to commemorate again one of the most significant events in all of human history. Actually, many including some historians consider it to be the most significant event. We’re referring, of course, to the famed Apollo 11 Moon landing on July 20th, 1969, when people left their home on Planet Earth and journeyed to another world in space.

A Sunrise Partial Annular Solar Eclipse For The Northeast

In last month’s installment the Western part of the country was favored with a total lunar eclipse. This month the Northeast gets its turn—this time for a solar eclipse. As was the case in May, this will also largely be a “horizon-hugging” event requiring an unobstructed one to be seen to advantage. Despite the challenge, this will be well worth making the effort to observe.

Moonset Total Lunar Eclipse For The West

This month the western part of the country gets to see an eclipse of the Moon—and next month the northeast will glimpse an eclipse of the Sun. (see the June Sky Talk). This will largely be a “horizon-hugging” event, with the most dramatic views being along the coast.

How Big Is The Moon?

A simple question, right? But it depends on whether you mean how large in actual physical size our satellite is—or how large does it appear in the sky. The answer to one is straight forward, but that to the other is both complex and surprising.

Dual Elongations of Both Inner Planets!

An “elongation” is the term used to describe the position of the inner planets Mercury and Venus with respect to the Sun in the sky. It can be a Greatest Eastern Elongation in which the planet appears at its greatest distance east of the setting Sun in the evening—or a Greatest Western Elongation where the planet is at its greatest distance west of the Sun in the morning sky.

The evening sky this month offers a great opportunity to see the Solar System’s two planetary extremes among the five bright naked-eye planets in terms of their orbital motion—sprinting Mercury and sluggish Saturn!

This Year’s Christmas “Star”!

The planets Jupiter and Saturn will come together this month in a spectacular conjunction low in the southwestern sky after sunset just in time for Christmas, recreating that famed “Star of Bethlehem.” These two worlds have been near each other in the evening sky since late summer, drawing ever-closer together from week-to-week in preparation for this month’s big event.

The Unpredictable Leonids

Wow – a meteor shower with an average rate of just 15 “shooting stars” an hour at its peak but one that has on occasion suddenly exploded at a rate of 40 per second! That’s the famed annual Leonid’s, which occur this year on the night of November 16th into the morning of the 17th. No other shower in recorded history has produced such an intense burst of activity—nor been so erratic and unpredictable.

Mars Arrives At Opposition!

In October the planet Mars makes another of its once every 26 month visits to the Earth and blazes like a ruddy-orange beacon above the eastern horizon after sunset. Normally the most disappointing of the five bright naked-eye planets (see below), it now takes center stage and dominates the night sky!
