1. (2020高二下·潍坊期中) 阅读理解A planet the size of Jupiter has been discovered and it is one of the hottest ones known to us. This has made scientists think about how planets are formed.
Planets such as Earth have more oxygen than carbon, but what if the composition(组成)is just the opposite? This is a question opened up by a recent discovery of a diamond planet by US and UK scientists. The planet is 1200 light years away from Earth and was observed using NASA's Spitzer Space Telescope. Dr Marek Kukula explained that researchers initially used the Super WASP(Wide Angle Search for Planets) robotic observatories operating continuously, all year around. They detected the planet, then it was observed with the Spitzer Space Telescope, which detected the heat coming from the planet, and from that heat signature they can tell what this planet is made from.
The planet is very different to Earth. "It's giant planet," explains Dr Kukula, "a gas planet, a bit like Jupiter in our solar system. But the interesting thing that they've discovered is that it has a very different composition to the planets in our solar system. This planet has more carbon than oxygen." This suggests that there is more than one way to make a solar system and the range of planets in the universe could be much wider than previously thought.
Dr Kukula says that if there are smaller planets in the same solar system with a similar composition, rich in carbon, their rocks could be rich in minerals such as carbon and diamonds, unlike Earth which has silica (硅石), the sand that rocks on Earth are made from. "This is where this diamond planet idea comes from; they haven't actually detected a diamond planet yet," explains Dr Kukula.it' s hypothetical (假设的), "but you can imagine strange landscapes with black graphite rocks lying around and the surface could be covered with sticky liquids instead of water".
