The planet Vulcan
By: D. Vogt
Inside the orbit of planet Mercury, a little over one-third as far from the Sun as Earth, lies a region of space which appears to be entirely empty. This is an unusual feature of the inner solar system, most of which possesses a variety of...

On the Earth, a dead body is quickly decomposed by bacteria, its remains reduced to bones and the material essentially recycled by nature. On other planets, however, there are no such bacteria - and so bodies do not decompose. Following our experiences leaving objects on...
A look at the latest theory on the formation of planets of our solar system
By: D. Vogt
According to current theory, the formation of the planets of our solar system occurred as a result of collisions between increasingly large bodies of matter within a flattened cloud of matter circling the early Sun, known as a protoplanetary disk. Essentially, through accretion, these collisions...
Classifying the Universe: The story of Galaxy Zoo
By: D. Vogt
The Galaxy Zoo is a public science project intended to solicit amateur astronomers and members of the public to assist scientists in classifying types of galaxies around the universe. Since 2009, a second project, Galaxy Zoo 2, has been following up on results from the...
Where did the moon come from?
By: D. Vogt
Earth's Moon is our closest and most regular celestial companion. It is also a relatively large one - especially in the inner solar system, where only Mars has other moons, and both are very small. This makes it all the more frustrating that the origins...
The history and future of the universe
By: D. Vogt
Today, modern physics and cosmology has been able to construct what we believe is a relatively accurate model of the history of the universe to date, as well as what we believe are more or less viable guesses at what is likely to occur over...
Should People be Allowed to Live on Mars
By: John Traveler
Before this question can be considered in realistic terms, the answers to two other questions need be forthcoming; Can people get to Mars alive, and once there, can they withstand the harsh environmental conditions they will be subject to? One thing is for sure, Mars...
What is the Oort cloud
By: D. Vogt
The Oort Cloud is a theoretical spherical region of comets found beyond the Kuiper belt and the scattered disk (now known to exist), and stretching as much as an entire light-year away from the Sun. These comets, if they exist, would primarily consist of ice...
Space exploration: Implications if life is found on Europa
By: D. Vogt
If life is found on Europa, it would hold immense implications for the future of space exploration and, for that matter, of many other aspects of human life. In particular, finding life on Europa, even primitive micro-organisms (which is most likely what would be found)...
By: Slawomir Puk
Somewhere in secret files in the United States and the CIS, are pictures that, if magnified, would show your house, your family’s car, and perhaps even you, walking down the street. All these would be taken by spy satellites, hovering high above Earth’s...
