How does the asteroid belt affect Earth? Are there comets in the asteroid belt? What is the asteroid belt next to? What is the asteroid belt? How did the asteroid belt acquire its structure? Why doesn't the Kuiper belt form a planet?
When speaking of the possibility of liquid water on other planets, some scientists refer to the“Goldilocks problem”.That is, Venus is too hot, Mars is too cold, and Earth is just right. (1) Which of the following statements can best describe the main idea of the passage?
Planetary climates are enormously complex, with many, many variables to account for—especially if you want to keep your planet in the “Goldilocks” zone where it’s exactly warm enough for water to be liquid but not so hot that it boils. Heat can come from a planet’s sun, but ...
Scientists calculate that as many as one in five sunlike stars may harbor an Earth-like planet in the so-called "Goldilocks" zone — a region around a star thought to be just right for liquid water to exist. Researchers are now taking that a step further, looking for water and other sig...
Our asteroid belt, which is situated between Jupiter and Mars, has traditionally been seen as something of a nuisance. Every once in awhile one of these rocks dislodges itself and heads straight for Earth, what often results in a cataclysmic impact. But ironically, as a new study from the ...
Specifically, the model Musk has in mind is that “flights” to Mars will be funded by the passengers riding on them, the same way public transportation works on Earth—and the key will be to bring ticket prices down far enough that a million people will buy one. Or as he explained to...
Another theory,as I describe in the chapter “Planet Smell” inThe Other End of the Leash, is the “guy-with-a-gold-chain” hypothesis. Perhaps dogs roll in stinky stuff because it makes them more attractive to other dogs. “Look at me! I have dead fish in my territory! Am I not ...
