Barred vs Unbarred Spiral Galaxies (The Differences!)

Scientists use four terms to differentiate the different types of galaxies: spiral galaxies, barred spiral galaxies, elliptical galaxies, and irregular galaxies. This article assesses the similarities and differences of the barred spiral galaxy vs. an unbarred spiral galaxy. The main difference between a barred spiral and unbarred spiral galaxy is the large bar that runs … Read more

Why Do Jovian Planets Have Rings? (Explained!)

The Jovian planets are comprised of four planets, all gas giants, and all with a far higher gravitational force than that of Earth. Outside of their gigantic size, the Jovian planets are also known for their many moons, along with their rings; none more breathtaking and visible than the rings of Saturn. Jovian Planets all … Read more

How Dense Are Saturn’s Rings? (Explained!)

Thanks to its gigantic size and unique ring formations, Saturn is the most recognizable planet in our solar system. While the rings appear flat and smooth, we now know that they are collections of rocks and ice balls that range in thickness from 10 meters to 1km. This may sound like a lot, but it … Read more

Is The Hubble Telescope Reflecting Or Refracting?

The Hubble telescope utilises an optical design referred to as Cassegrain reflector optics meaning it’s a reflecting telescope. This means that the Hubble has 2 mirrors within its chassis, the primary is a concave mirror and the secondary is convex.  There are 3 main reasons why the Hubble is a reflective telescope. Firstly, reflective optics … Read more

Why Are Inner Planets Rocky? (Explained!)

Inner planets are rocky thanks to their proximity to the sun. The heat emitted from these giant stars means that only materials with the highest melting points can survive, such as metals and rocks. These materials collide and join to form the base of a rocky planet. Continue reading to discover how these rocky clumps … Read more

What Is A Peculiar Galaxy? (Explained!)

A Peculiar galaxy collides, interacts, is cannibalistic, has a strange shape, or is considered diverse somehow. These are the unusual galaxies in their size, structure, and composition. They form from the interaction of two or more galaxies. Continue reading to discover the shape and composition of peculiar galaxies, how scientists first discovered these oddball formations, … Read more

What Makes Stars Explode? (Explained!)

Our night skies are filled with them, bright piercing lights shining back at us, celestial beings that have an almost infinite lifespan, burning endlessly for as long as we can imagine that is. However, just like how everything dies in the end, so do these gargantuan balls of fire. As for the main reason what … Read more
