This suggests that our Solar System isn't a typical planetary system, but a relatively rare one. When we look at planets around other stars, we see that planets of a similar mass to Jupiter are found in Earth's spot.这表明，我们的太阳系不是一个典型的行星系，而是一个相对罕见的行星系。...
This first stage produces simple molecules, which can then recombine to make more complex molecules if this astonishing experiment is successful. What we're going to do now is warm the system a little to see what the ice does.第一步产生简单的分子，如果这个惊人的实验成功的话，这些简单的分子就...
We can consider the gravitational attraction exerted by the other planets to be negligible, therefore the greatest effects on the Earth will be those produced by the sun and the moon. These three bodies attract each other, however, the greatest effect is in the Earth-moon interaction. Both ...

Reflector telescopes offer larger apertures for the price, resulting in deeper, more detailed views of the planets, the moon, and even deep-sky objects such as galaxies and nebulae. See my review of the Apertura AD8 Dobsonian Reflector as a fantastic example of this type of telescope. Which...
