How Is the Sunspot Cycle Directly Relevant to Us Here on Earth?
The sunspot cycle, occurring every 11 years, influences Earth's weather, communication, and power. Solar flares can disrupt technology. Preparedness is key.
Why Didn’t a Planet Form Where the Asteroid Belt Is Now Located?
The asteroid belt is an enormous region of space between the orbits of Mars and Jupiter. It contains millions of rocky bodies ranging in size from small particles to large asteroids. For centuries, astronomers have been looking for planets there, sometimes mistaking large asteroids like Ceres, Vesta, and Pallas for planets. In the end, though, no real planet was ever discovered in this area.

What’s the Difference Between LEO, MEO and GEO Satellites?
As of the beginning of 2023, nearly 15,000 satellites are orbiting our planet. With so many orbiting bodies circling the Earth, it's a miracle they don't crash into each other, right? It might seem like magic, but in reality, it's because they aren't all orbiting at the same height. Let's take a closer look at what LEO, MEO and GEO satellites are, and why more companies are investing in LEO and MEO satellites to support space exploration.

A Pulsar With Planets
Pulsars emit deadly radiation, disintegrating DNA and making them dangerous. Surprisingly, some have planets orbiting them, defying current theories.
What is Celestial Navigation?
We've been dreaming of the stars for longer than we can remember, staring up at the twinkling lights that fill the night sky and wondering what they are. We've even written songs about them. Centuries ago, before the advent of GPS, explorers and adventurers relied on celestial navigation to help them map a path to their destination. What is celestial navigation, how does it work and when was it relied upon?
What Experiments Did Scientists Conduct on the ISS?
ISS: A scientific marvel in space. Over 3,000 experiments conducted, from zero-gravity Parkinson's research to interstellar 3D printing. Exciting future ahead!
Why Are Satellites So Important?
SpaceX has been launching 60 satellites at a time as part of their Starlink constellation. When complete, this network will provide high-speed, low-latency internet to the entire world. This project provides one example of a type of satellite orbiting at various heights above the planet’s surface. Why are satellites so essential?
