With nearly eighteen centuries of naked eye observations of sunspot activities, scientists have a treasure trove of information about solar activity. The first person to realize that collating multiple sources of historical information about solar sunspot activity could yield results was astronomer Rudolf Wolf who...

A sunspot is defined as a cooler darker spot appearing periodically on the sun's photosphere; associated with a strong magnetic field. Sunspots have been appearing on the sun for as long as astronomers can remember however; it wasn't until late 2002 when the most detailed...
What does a lunar eclipse look like from the Moon?
By: Jeffrey Graf
A lunar eclipse occurs when the Earth passes between the sun and the moon. As viewed from the earth, we see the Earth's shadow pass across the Moon. As viewed from the moon, we would see the sun go dark during the day, much like...
The development of sunspots and sunspot groups
By: Alexander Darracott
To obtain a complete picture of how Sunspots develop, it's important to understand the Sun itself: how heat is generated and transported through the Sun's different layers, its rotation, its magnetic field and its surface.The Sun is a huge, immensely hot circular concentration of...

Since the dawn of civilization and long before, night falling in the middle of the day, darkness seeming to eat the sun, has induced terror. People like a certain amount of stability in their day to day lives, we always have, and nothing is...
Dyson Spheres - science-fiction or science-fact?

By: Kristin Kurtzweil
Pagan holidays are intrinsically connected to the cycles of the seasons and, thus, are linked to both astronomical phenomena and agriculture. The spring equinox (also called the vernal equinox) in particular occurs circa March 21st by current time-keeping standards and is astronomically one of two...
A look at the types of lunar eclipses
By: Kimberly Humphrey
The definition of a lunar eclipse is when the moon moves into the shadow of the Earth created by the sun, therefore, distorting its image and color. There are three basic types of lunar eclipses: the penumbral eclipse, a total eclipse, and a partial eclipse...

How to View the Sun SafelyThe human eyes are amazing pieces of biology. They are able to process huge amounts of visual information. An interesting piece of information is that even if we touch them with our finger, a contact lens or a piece of...
