Many hundreds of scientific experiments are performed aboard the International Space Station (ISS). Some of these experiments help us to understand and take action against global climate change, a very real threat to life on Earth as we know it. But how does space science help us to combat climate change? It can be tricky …

What Are Gravitational Waves? When an object moves, it creates waves in the fabric of space-time. The faster the object is moving, the more powerful these waves become. When the wave reaches us, we see them as ripples in spacetime, known as gravitational waves. Gravitational waves are ripples in space-time caused by massive objects moving …
A long time ago, in a galaxy far, far away… This is perhaps one of the most iconic references to galaxies in modern popular culture. But what exactly is a galaxy, and how many do we know about today? The mysteries of the cosmos have played a pivotal role in the development of human civilization. …
Vacuum energy has been measured since the early 20th century, but its existence remains controversial. Why? Because vacuum energy isn’t directly observable. How does it work? What is it? And why should anyone care? What Is Vacuum Energy? The concept of vacuum energy was introduced by Albert Einstein in 1917. He suggested that empty space …
Ever heard of a black hole? No? That’s okay. A black hole is the result of a star that has exploded, leaving behind nothing but a tiny remnant called a mini-black hole. Mini-black holes are smaller versions of black holes. They’re not as big as regular black holes, but they do have some interesting properties. …
What is gravity force, and how does gravity force get transmitted from one object to another? Gravity is a natural phenomenon that causes objects at rest to fall towards the center of Earth. Since ancient times, it has been a fundamental force, but sometimes, it leaves us with more questions than answers. Thankfully, with the …
Asteroid impacts occur rarely, but they can be devastating. The last significant impact was 65 million years ago, when a huge asteroid struck the Yucatan Peninsula off Mexico, causing mass extinctions and changing the course of life on Earth. There are currently over 100,000 known asteroids in our solar system. Most of them are too …
Have you ever wondered why some stars are named after animals or plants while others are named after people? The International Astronomical Union (IAU) has cataloged over 100,000 stars. They are organized into groups called constellations, each representing a mythological figure from Greek mythology. In this article, we will learn the names of constellations and …
Black holes have a gravitational force that can consume all that comes within reach of the event horizon. When you think of that, even a mini black hole sounds absolutely terrifying. But what exactly is the size of these mini-monsters, and could even a micro black hole pose a threat? The mini black hole can …
What would happen if a meteorite hit the earth? Would it destroy our planet, or would it cause some sort of disaster? Meteorites are pieces of rock from space that fall to the ground. They come in various sizes and shapes. The largest recorded meteorite was found in Russia in 1908 and weighed over 7 …
