Galaxy Supercluster Walls – Filaments – in Space

Matter in space ranges in size from subatomic particles to galaxy superclusters. In fact, there are larger objects than those—complexes of superclusters called walls or sheets. These structures, as much as one billion light-years across, resemble fine gauze. They are the filaments of space.

Defining and Describing the Phenomena of a Coronal Hole

The Sun is over 15 million degrees hot, with most of its upper layers much cooler. Why then is the very outermost layer—the corona—suddenly a lot hotter? More than that, why does this hot outer layer have cool, dark, “coronal holes” in it? The answer involves magnetism.

Why Do Stars Appear to Twinkle or Scintillate?

Although the sun, moon, and planets slowly move across the sky, they give an appearance of stability. Light from them is steady, unflickering. Why are the stars different? Why do they produce a twinkling effect?

Why is the Sun Red During a Sunset

More accurate than any ordinary timepiece, the Sun rises and sets exactly on schedule. So why does the Sun redden as it lowers in the sky, approaching sunset? It can’t be because the Sun actually changes in some way. So it must be something else. What phenomena are involved?

The Milky Way: What is It? What Is It Made of?

It is easy to “miss the forest for the trees.” Let’s consider the forest in which Earth is located—our own galaxy—the Milky Way. What is the structure of the Milky Way? What kind of galaxy is it? Is it remarkable? Finally, what is the location in the galaxy of our Earth and of our Sun?

Saturn’s Perfect Hexagon

Imagine you could look down on the North Pole of the planet Saturn. What would you think if you saw a perfect hexagon? That you were dreaming? Well, dream on… it’s true!

Asteroid Mining – Science or Science Fiction?

Is it merely science fiction, or could it become science fact that one day manufacturing resources could come from space, from within our own Solar System, by the process of asteroid mining? How plausible might it be? Can asteroid mining actually be accomplished?

Facts And Information About the Van Allen Radiation Belt

Cosmic particles, once a topic of mystery and science fiction, are found in abundance in Earth’s vicinity. In the late 1950’s, James Arthur Van Allen launched a probe to learn more about them. What exactly are the Van Allen Belts, and what are their secrets?
