What is really new is unknowable—by definition, the unknown can not be described or predicted. So serendipity is ubiquitous among scientific discoveries. For example, Kepler's proof for elliptical planetary orbits grew f...
Sunglasses provide protection from intense light. When the eye receives too much light, it naturally closes the iris. Once it has closed the iris as far as it can, the next step is squinting. If there is still too much light, as there can be when sunlight is reflecting off of snow, ...
Copernicus and Kepler still believed in this outermost sphere, but in fact it became obsolete when left without its original function. This new world order is clearly expressed by the ardent supporter of Copernicus, Bruno: "As soon as we realize that the apparent celestial rotation is caused by...
Kepler's design is still the major design of refractors today, with a few later improvements in the lenses and the glass to make them. Refractors are the type of telescope that most of us are familiar with. They have the following parts: a long tube, made of metal, plastic, or wood...
With Kepler's fancy equations, watching the planets move around the sun, we've been able to measure the distance to planets. With parallax, we've been able to measure the distance to stars that are really far away and get a 3D map of our galactic neighbors. But we're still not really...
How long is a day on Jupiter? How many days are in a year on planet Mars? What is Mars' orbital period? How long would it take to get from Earth to Ceres? How to calculate the orbital period of Mercury Describe the sun's life cycle What is the relation between Kepler's laws and...

So far 39 has discovered five new earth-sized planets beyond our solar system.These planets are hotter than the earths sun - much too hot frlife as we knowt. The Keplerteam predicts that they _40 (need) at leastthree years ( and possibly longer) to find anearth-like plant.The41 (...
a planet about six hundred light years away.It is the first planet in a"habitable zone"outside the solar system.That means the planet orbits a star like our Sun,but it is not too close to it,nor too far away.Because of this position,scientists say Kepler22b might have water,one of ...
What is really new is unknowable—by definition, the unknown can not be described or predicted. So serendipity is ubiquitous among scientific discoveries. For example, Kepler's proof for elliptical planetary orbits grew from his attempts to measure the areas & volumes of wine casks. ...
