Gravity Waves ... not gravitational waves ... move atmospheres and make pretty clouds. Have you ever looked up into the sky and seen bizarre cloud formations that look like waves on the ocean? These are gravity waves. Not to be confused with gravitational waves, and they’re caused by a balance of buoyancy and gravity. And of course these have been seen across the solar system.

Why stars can’t be trusted!

If you’re an astronomer you depend on accurate observations of stars, but there’s a problem. Stars are sneaky! Changing in size, brightness, color, they hide their chemistry, their age and even their companions from all but the cleverest observers. Stars explode precisely when they intend to. Betelgeuse took a brightness plunge, T CrB refused to go nova, and other failures to be predictable irk observers for good reasons. Let's talk about it.

From little Ingenuity to the future Firefly and all our Earth Science fliers, let's look at the buzzy scientists. NASA’s Mars Ingenuity helicopter showed us how wonderful a flying science platform can be on another world. Soon there’ll be a helicopter flying on Titan, but there are many other flying robots that’ll be helping us with all our science needs. 

What can we hope (or dread) to see in 2025?

Last week we talked about the 2024 strangeness. Now we’re gonna talk about the upcoming space stories for 2025 that we’re looking forward to. It’s a nice mix of new rockets, new missions and new fly-bys.

Last week we talked about the Einstein probe. So this week it is only natural that we talk about the man himself, Albert Einstein. He revolutionized the field of physics, played a vital role in the early 20th century and struggled to unite the forces of the Universe at the end of his career.

Another day, another space telescope! Today we’re looking at the newly launched Einstein Probe. A collaboration between the Chinese Space Agency and the European Space Agency. The mission has been operating since January searching the cosmos for short, bright flashes of X-rays.

Last week we talked about the mission. This week we’ll talk about Euclid of Alexandria, the ancient Greek mathematician who inspired the mission. Let’s learn about his life and the ground breaking work that made so much of our modern mathematics possible.
