Farewell, for now

Posted on April 28, 2023 by 7smessier45

I have always loved the stars, nebulae, planets, and all the space in between, but I never had a chance to seriously study them until this year. I am incredibly grateful that I was able to devote two classes (and a lab!) to learning more about the processes that govern solar system formation and how […] Continue reading →

Extremophiles: life finds a way

Posted on April 28, 2023 by 7smessier45

I remember first learning about extremophiles back in the sixth grade. Back then, I was fascinated by life’s ability to find a way to survive even in the ‘worst’ conditions. Now that I’m older, I am no less fascinated by these amazing organisms, their ability to thrive, and their connection to astronomy. (I only recently […] Continue reading →

All About Aurorae

Posted on March 5, 2023 by 7smessier45

As the title suggests, our topic for today is Earth’s aurorae (pronounced auh-ror-eye). These stunning displays generally occur in two symmetrical oval rings about the planet’s far northern and southern regions–Earth’s magnetic north and south poles. When they happen in the north, aurorae are often referred to as the northern lights or Aurora Borealis. Likewise, […] Continue reading →

M45 – The Seven Sisters

Posted on February 28, 2023 by 7smessier45

Hey, y’all, and welcome back!  Today, we’re taking a quick jaunt outside our solar system to visit the Pleiades.

More recently–but still a few hundred years ago–celestial navigation by Western cultures relied on a navigator’s understanding of the stars (and other heavenly bodies, including the sun), the […] Continue reading →
