Light pollution is big problem and it’s only getting worse. Not just near cities, but everywhere thanks to increased satellite constellations. How bad is the problem, and how can we fix it?
Nov 7th: Space Exploration Horror Stories
Oct 31st: Archaeoastronomy
Some of the earliest records we do have tell us what the ancient astronomers thought about the heavens, and how they used the changing night sky in their daily lives. More with @AstronomyCast at #365DaysOfAstro
Oct 24th: Astronomical Naming Schemes
Space is a big place, with lots of galaxies, stars, planets, moons, and that means a lot of names. So how do astronomers name stuff, like comets, asteroids, exoplanets, craters?
Oct 17th: Smashing Asteroids for Science!
This week we saw the incredible image of DART smashing into asteroid Dimorphous. Beyond avenging the dinosaurs, what can we learn scientifically from this and other asteroid/comet impact missions.
Oct 10th: 65 Years of Space: Sputnik 1 Anniversary
It’s been about 65 years since the Soviets launched the first orbital satellite into low Earth orbit: Sputnik 1. Let’s look at the impact that Sputnik had on the history of spaceflight.
Oct 3rd: The Side Effects Of Clean Energy
To battle climate change, we’ll need to rapidly move to carbon-free sources of energy. But this technology isn’t a free lunch. They require metals, generate waste and deplete the environment. What’s the best way to balance this shift?
Sep 26th: Climate Change: Looking at the Variables
Climate change is on our minds these days, with increasing wildfires, droughts and floods. What are the variables that play into a planet’s changing climate, and what can this teach us about the search for habitable planets across the Milky Way?
Sep 19th: The Rocket Race Towards Reusability
Last week we talked about how single-use rocketry has changed over time, and the role it still plays in launching payloads into orbit and beyond. Today we’ll address the stainless steel elephant in the room and talk about the shift to reusability.
Sep 12th: Artemis & The Decline of Single Use Rockets
On the day that we’re recording this, NASA’s Space Launch System is about to blast off. But everyone is expecting it’ll be delayed to October. When it does launch, it’ll be the most powerful rocket on Earth. Well, until Starship blasts off. So are we about to see the end of single-use rockets and enter the era of reusable rocketry?
