Deep-Sky Objects: Marvels Of The Night
Did you know that there are many objects you can see in the night sky that are neither stars nor planets? Were you aware that many clusters or clouds of glowing deep-space gas can be seen with your unaided eye, and dozens more are visible with simple binoculars? Have you heard that some deep-sky objects are so large and bright that we can see them even though they are thousands of light-years away, up to halfway across the galaxy? And that there are even other galaxies that we can see with our unaided eye? And what are the planets and constellations doing in our skies in October? Join us by Zoom to learn more!

Venus: Our Brightest Planet
Did you know that Venus is the brightest object in the night sky other than the Moon—so bright that it is often mistaken for an airplane? Or that these next several months are the best times to see Venus in the evening since early in 2020, and that it won’t be this nice again until spring of 2023? Are you aware that humans have sent nearly forty missions to the planet Venus—and that almost half of them failed? Have you heard that the surface temperature of Venus is hot enough to melt lead, and the surface pressure is great enough to crush a submarine? And what are the other planets and constellations doing in our skies in September? Join us by Zoom to learn more!
Saturn: Our Most Beautiful Planet Did you know that Saturn is the furthest of the planets that we can easily see with our unaided eye? Have you heard that, while Saturn is many times larger and heavier than Earth, it is so light for its size that it would float on water? Are you aware that, while humans have sent nearly 50…

A Brief History of Rockets
What do the Apollo missions, the Hubble Space Telescope, the International Space Station, every planetary mission, and most of the world’s nuclear deterrent forces have in common? They all depend on rockets! But what, exactly, is a rocket? How does it differ from supersonic or hypersonic travel? Who invented the rocket? Are there different kinds of rockets? Why do some have multiple “stages”? How were rockets first used? When was the first manned rocket, or the first mission to other planets? Speaking of planets—what are the planets and constellations doing in our skies in July? Did you see Midland’s partial solar eclipse last month? Join us via Zoom to learn more!
The End of the Sun: How Large Stars Die The Sun has been a constant source of light, warmth, and life for all of human history. But, will it always be this way? What will happen as the Sun ages? Will it get colder? Hotter? Larger? Smaller? Believe it or not, the answer to ALL of these questions is—yes! Have you ever…

But all of those planets orbit our sun. What about all the other stars? Astronomers have been hoping to find planets around them—exoplanets—for centuries. Yet did you know that not a single exoplanet was found to orbit…

Have you heard that such objects might be more common in our universe than normal stars? And that, despite this, none are visible with the unaided eye, and that astronomers with…
