Hello Astronomy Lovers,  This month's blog post will be about the life cycle of stars! Almost everyone knows the life cycle of humans and animals, but most people don't even know that there is a life cycle for stars! Today, we will be learning more about the process in which a star is firstborn, how it carries its life, and how it ultimately dies and gives way to more stars just like itself! We will also be diving into our own sun and see how its fate will turn out too! If you are ready to learn about one of the many wonders of the universe, I am ready to input some knowledge into your brains! Let's just get into it! What do I mean by the life cycle of stars? To be honest, the life cycle of a star is almost the same as the life cycle of any human or animal in the world! A star is born, then it lives its life producing energy to its nearby planets or stars, then dies to make way for more stars just like itself to form! To Understand more, we can dive deeper into understandin...

Ever looked up at the sky and wondered, what's the most mysterious thing in existence?  Today, we are looking at something we know very little about. In the modern world, we've been used to knowing that humanity has found, or known the majority of the things we observe in the world, and in the universe, but it's important to realize that there are many many more things in the world and in the universe alike that humanity has a whole still doesn't know about, and quasars are amongst them. What is a Quasar? A quasar, or quasi-stellar object (QSO) for short, is basically an extremely "luminous active galactic nucleus (AGN) in which a supermassive black hole with a mass ranging from millions to billions of times the mass of the sun is surrounded by a mostly gaseous accretion disk" [1]. Now, what does this all mean? In simple terms, a quasar is a black hole with a gaseous accretion disk of gas, dust, and other materials, which sits in the middle of super active gal...

Hi, Science/Astronomy Enthusiasts,  Today, we are going to be learning about what Dark Matter is. Many people get Black Holes and Dark Matter confused, but they are totally different concepts in Astronomy, and in some aspects, very similar also. The structure of this post is going to be what my post in black holes was like, a little bit of background, and then its detailed definition with an explanation. Now get ready to get blown away from all the fascinating facts about Dark Matter! Dark Matter's Background You might be thinking, Dark Matter sounds like something dark, and while literary, it might not be "dark" after all. We still don't know what dark matter is, but we do know it exists and that it has some unique properties. Sounds strange right, wait for it, there are many more interesting things about this. In its simplest terms, Dark Matter is an unknown form of matter created to solve the Missing Mass Problem, but to further understand Dark Matter, we have t...

Hi Astronomy Enthuists, First of all, I want to start out by wishing all of you a very happy and prosperous New Year. In today's blog post, I am going to be exploring the famous mission that put a man on the moon which is, of course, the Apollo Mission. I am going to make this post a little different in that I'm going to explain to you guys the Apollo Mission in-depth, separating the different aspects into bite-sized chunks, making all the info much easier to understand.  The Apollo Space Mission's Logo Before we get into the actual Mission, let's talk about the Spacecraft which took the 3 astronauts to the moon and the components of the spacecraft a little. Saturn V The Saturn V was the rocket that took the supplies, crew, and everything needed to get to the surface of the moon. The rocket is massive at 363 ft or 110 meters. The Saturn V was split up into 3 stages: S-IC, S-II, SIVB, and the lunar module, Service Module, Command Module, and the Lunch Escape S...

Hello Science Enthuists, id you know that Soil is the greatest destroyer of Houses and Buildings in the United States. Have you ever seen a crack in the walls of your house or a building and thought it was because of earthquakes and tornadoes? Well, the cause of it is from nothing but from Soil. Yes, Soil causes more damage in the US than Earthquakes, Floods, Tornadoes, and Hurricanes combines! This phenomenon is called Expansive Soil. Different Types of Soils in the US  Expansive Soil Expansive soil is when the soil (most expansive soil is clay) change their volume depending on the moisture content of the Clay. Clay swells when there is more water and shrinks when there is less water. Even though this might be a small change, it can cause a lot of damage to the building on it. This is a small mechanism where the size, shape, and arrangement of the changes based on the amount of water the soil is being exposed to. This kind of soil is not avoidable since large po...

Whats E=mc^2? Well today, you are going to find out. A couple of weeks ago, I was watching this video on YouTube about the efficiency of black holes in creating mass into energy. It was all about the equation e=mc^2. I always thought what the equation was very complex but after watching the video, I understood the meaning behind the famous equation. What it means? So to keep it simple, E is energy; m is mass, and c is the speed of light squared! So, Albert Einstein said that energy equals the mass times the speed of light squared! That means that a 5 kg cat is enough to power the country of Norway for 2 years. That much energy from a 5 kg cat is really big. But sadly, we can’t harness 100% of the mass. The best method of getting energy from mass only gets about 0.000007% of the energy from the mass of the object. To get energy from mass really efficiently, there are 4 ways: 1. Chemical reaction 2. Nuclear reaction 3. Antimatters reaction Chemical Reactions Chemica...
