How the universe formed

Before the beginning of time there was darkness and silence. No visible reactions, no audible sounds, which in our time stands as the clock to our universe. If there was any physical existence, little was known on the condition of the reactions taking place at...
Why manned interstellar travel is impossible

Understanding the Danjon Scale of Lunar Eclipse Brightness
By: D. Vogt
The Danjon Scale of Lunar Eclipse Brightness is a handy method of estimating the brightness of a particular lunar eclipse, and therefore having an easy of comparing the brightness of different lunar eclipses. It identifies five levels of brightness, ranging from very dark to a...

Binoculars may not immediately seem the most obvious tool when it comes to astronomy but in many ways a pair of binoculars has advantages over a telescope, especially for the beginner. Binoculars are portable, durable and are easier in general to use when compared to...
Jupiter: Basic facts
By: D. Vogt
Jupiter is the fifth planet in the solar system from the Sun, and by far the largest - in terms of mass, more than twice the size of all other planets combined. Viewed from Earth, the planet rivals or exceeds Mars in terms of brightness...
Jupiter: largest planet in the solar system
By: D. Vogt
