An Examination of HII Regions

Clouds of ionized hydrogen are commonly found in spiral and irregular galaxies. These fascinating regions in space consist of thousands of stars. Find out what they are, how they are formed and what their eventual fate is.

Understanding Asteroids in the Kirkwood Gaps

Kirkwood gaps are an interesting phenomenon occurring in the main asteroid belt between the orbits of Jupiter and Mars. Find out what they are and why they occur, as well as whether or not any asteroids in the gaps pose a threat to Earth.

Longshore Drift and How It Occurs

Ever notice how the sand recedes from the beach and gets deposited somewhere else? This happens due to a process known as longshore drift that is responsible for shaping the coastlines. We will explore what the process is, how it works and see what effects it has on those living along the coasts.

Different Parts of a Black Hole

Black holes are a dynamic structure within the confines of the universe. To understand the different parts, one must look at each one and discover its place within the whole. By defining a black hole’s existence, the true nature of the universe can begin to be revealed.

The Life, Works and Achievements of John Couch Adams

John Couch Adams was a brilliant scientist who made numerous significant contributions to the field of astronomy. We will look at his life and his contributions to the field of astronomy, particularly to planetary science, the Moon and the Leonid meteor shower.

The Facts About Lenticular Galaxies

Lenticular galaxies are intermediate galaxies in the Hubble classification scheme between elliptical and spiral galaxies. In this article, we will explore some interesting facts about these island universes, including how they are thought to be formed.

All About the Hourglass Nebula

The Hourglass Nebula is a unique and fascinating planetary nebula. Planetary nebulae are formed from dying stars and are important in the evolution of a galaxy. We will explore some interesting facts about this fascinating nebula, including how it was formed and what gives it its unique shape.

How Are Waterfalls Formed?

Waterfalls are spectacular displays of the beauty and power of nature. The highest waterfall in the world is Angel Falls in Venezuela at a height of over 3000 feet. We will explore how waterfalls are formed and the processes behind such formations.

Understanding the Barycenter of the Solar System

Barycenter is commonly known as the center of mass. In this article we will explore what the concept of the barycenter is, what the barycenter of the Solar System is and how it influences the other planets and the Earth-Moon system.

Understanding the Escape Velocity of the Earth

What exactly is escape velocity? In this article we will explore what this concept is, how to calculate this velocity for an object and also look at how this velocity varies for different celestial objects.

Information About Circumpolar Stars

Do you know that there are some stars that never set? They are circumpolar stars. In this article we will explore what they are and why they never set below the horizon. Also, we will explore what the pole star is and the various northern constellations that are circumpolar.

Solar and Lunar Eclipses and the Saros Cycle

Eclipses, solar and lunar, occur quite frequently, and you might be surprised to know that they repeat themselves over time. The Saros cycle is a cycle of eclipses. Read on to find out more about this cycle of eclipses, how it works and who first noticed this natural cycle.
