We live in the Milky Way galaxy, a member of a collection of around 80 galaxies known as the Local Group.
An asteroid called 2024 YR4 currently has a small chance of hitting Earth in December of 2032. While it’s not massive enough to be considere...
How long would it take to fly to Mars? What about Pluto? Let’s look at how long interplanetary travel takes.
Right now, in a nebula not so far from you, new stars are forming. How do stars form, and how close to Earth does star formation happen? In...
The universe is expanding, but how different methods for measuring its expansion give us different results. We call this the Hubble Tension.
Earth is always moving through the Solar System, and the Solar System is always moving through the galaxy, so just how fast are we moving th...
How many stars can you see with the naked eye at night? 40 or 50 thousand? Or is it 100,000 stars? Have you ever tried to count? Well, a few...
Computers, tablets, and phones have become very fast. The latest multicore processors are capable of an incredible number of calculations ea...
Let’s study the mystery of magnetism, exploring the tiny particles and invisible fields that govern this powerful interaction.
Have you ever squinted at a shimmering lake or felt blinded by the reflection off a wet road? That's glare, and it's not just uncomfortable...
A nova called T Coronae Borealis erupts every 80 years and your only chance to see it is sometime between right now and September of 2024.
Imagine sending massive amounts of data from our spacecraft and receiving high-res video in minutes, not hours or days. It might sound like...
The radio spectrum is a fascinating realm of invisible energy carrying everything from your favorite radio station to your Wi-Fi connection...
We’ve all heard this number before – 9.8 m/s² – But what does that really tell us? And what does it have to do with our weight?
Mars is a world of towering mountains, vast plains, and deep canyons. Today, we're going to take a look at one of the most remarkable featur...
Most of the universe is made of a type of matter that doesn’t interact with light—dark matter. This is a big deal—throughout history we’ve s...
Physicists have finally detected the elusive oxygen-28 isotope, but the observations are surprising and unexpected.
In 1942, a team working on the Manhattan Project were the first scientists to build a nuclear fission reactor, but it was only the first *ma...
How many planets do we know of outside of our own Solar System? Are any of these planets habitable? How do we even find them?
There is a moon in our Solar System that is considered to be the most volcanically active world that we know of. This Moon is one of Jupiter...
