The Martian Dichotomy - an article written in 2012
There is a remarkable difference between the northern hemisphere of Mars with its uniformly smooth, flat and low topography, and the southern hemisphere with its high ground pock-marked by thousands of craters, as shown in the topographical image above. It is this dichotomy that I seek to explain, but this theory is just one of many that might explain the dichotomy — it just happens to be the one theory that I prefer.
Solar Eclipses - an article written in 2009
If you lived on Mars, the word “eclipse” probably wouldn’t appear in your dictionary. The moons Phobos and Deimos are so small that if they did pass in front of the Sun, it would hardly be noticeable. The same would be true on Mercury or Venus where there are no moons at all. In fact, solar eclipses like we see them on Earth, where the Moon passes between the Earth and the Sun, could be unique.
Sir Isaac Newton - an article written in 2005
Isaac Newton was born in January 1643, in Woolsthorpe Manor, Lincolnshire. His father, an uneducated but wealthy man, died 3 months before Isaac was born. His mother, Hannah Ayscough, remarried a local church minister when Isaac was 2 years old, and the young lad was sent to live with his grandmother, Margery Ayscough. He felt very bitter toward his mother and stepfather for making him virtually an orphan, and his childhood was not a happy one.
Nebulae - an article written in 2009
The term “nebulae” was originally used by astronomers to refer to any fuzzy patch in the sky that could be easily distinguished by a telescope, but was not sharp like stars or planets. “Nebulae” now refers to clouds of interstellar dust and gas made visible by their interaction with nearby stars or star remnants. In most cases, this material is about as dense as cigarette smoke, but the enormous quantity of it makes it visible thousands of light years away.
