In the far reaches of the Universe, you’ll find amazing events, celestial bodies, and mind-blowing chemical reactions that, if we’re honest, we’re not close to, as some can be world-ending. One of these is the quasar. Quasars are some of the brightest objects in the universe. They are very distant galaxies, which means they are …
Space is a pretty big place. Not the most groundbreaking piece of information that has ever been written, but it’s pretty hard to comprehend sometimes just how big the void that our planet flies through is. It’s a scale that the human mind can’t wrap our heads around. For example, take our closest celestial neighbor. …
Neutrinos are subatomic particles that pass through matter without interacting with it. They are extremely weakly interactive and therefore pose no threat to humans. Neutrinos come from nuclear reactions within stars and other celestial bodies. The neutrino radiation emitted by these sources is very low energy and does not pose any danger to living organisms. …
There are four commonly taught states of matter: gas, liquid, solid, and plasma. You probably came across these in school and they’re found in everyday life (yes, even plasma). But there’s also a fifth state of matter, and this one isn’t so clearly defined: exotic matter. Exotic matter is matter that doesn’t behave as we …
The asteroid that struck Earth 65 million years ago was large enough to cause global devastation. It slammed into the Yucatán Peninsula of Mexico, creating a massive crater that is now known as the Chicxulub Crater. Scientists believe the impact triggered a mass extinction event that wiped out the majority of life on our planet. …
We all know that the earth is spinning. Not only does it spin on its own axis of rotation, but it also orbits the sun as it spins. The moon spins as it orbits the earth. And even the sun spins at the center of our solar system. In fact, every planet, moon, asteroid, star, …

Satellites are often confused with spacecraft, but they are two very different things. What exactly is the difference between them? Satellites are man-made objects that orbit Earth at altitudes ranging from hundreds to thousands of miles. They are usually used for scientific research or military purposes. A spacecraft on the other hand is a vehicle …

The United States government spends billions of dollars each year on NASA research and development. In fact, NASA has spent nearly over $100 million per day since its inception. However, SpaceX is a private company that was founded by Elon Musk. They offer low-cost launch services to customers who want to send their satellites into …
String theory has been around since the 1970s, but it was only recently that physicists began to consider its merits seriously. Why does string theory persist despite the knotty physics? What Is String Theory? String theory is a bit of an oddball in theoretical physics. It’s not just that it’s hard to understand; it’s also …

The Earth rotates around its axis once every 24 hours, causing the sun to rise and set. This rotation causes the sky to appear dark at night because the light from the sun is blocked by the atmosphere. On the other hand, the moon does not rotate around the Earth, so it always faces us …
