These nights the first few hours after nightfall let us see the brightest part of our Galaxy. The next night it’s clear, you’ll find the Moon is absent. So if you’re away from city lights and you let your eye dark adapt for a few minutes, you’ll see the creamy glow of the Milky Way right overhead, splitting the sky in half from North to south. Tune in to hear what you need to catch that perfect glimpse of the stellar night sky.

There’s an eclipse happening! It happens September 17 at 10:12 p.m. Eastern Daylight Time. Since the Moon orbits around us at a speed of 2,287 miles an hour, it normally takes a full hour for its 2,160-mile-wide body to plunge completely into Earth’s dark umbral shadow. Tune in to hear more about what’s happening in the sky!

Saturn arrives at its closest point to Earth of the entire year. So let’s locate it. It’s the ONLY bright star in that entire section of the heavens. We’ll also discuss Saturn’s composition and its journey around the sun.

This week we’ll see a Perseid meteor shower. But if clouds spoil the spectacle for you, there will be lingering meteors. This shower’s intensity falls off rapidly after peak, so later you might only see a meteor every 3 minutes after midnight. Tune in to hear about the reddish stars and what to check for the in the sky!

A century ago the famed astronomer Percival Lowell believed an unknown “planet X” was gravitationally tugging on Uranus and Neptune. So the wealthy Lowell founded an Arizona observatory to try to detect this ninth planet. We’re reminded of all this because this past week is when Pluto has come to its closest to Earth of 2024.

All the interactions in the universe can be explained by gravity, electromagnetism, and the two forces, strong and weak, that operate only within atoms. This week: The String Theory.

On Tuesday night the crescent Moon hovers next to the famous blue star Regulus. As the brightest luminary in Leo the Lion, the ancient Persians considered it one of the “four royal stars,” famous for sitting in the center of the zodiac, which is why it sometimes meets the Moon.
