Space isn't always cold. In fact, it can get pretty hot.
太空不总是冰冷的,它也可以很炎热。
In the darkest parts of space, temperatures can reach -454 degrees Fahrenheit. But if you're orbiting near Earth in the sunlight, space is a toasty 250 degrees Fahrenheit. Astronauts' spacesuits are white to reflect the heat they encounter while floating above the Earth.
在太空最阴暗的地带,温度可达零下270摄氏度(零下454华氏度);但若处于地球附近的阳光里,温度可达滚烫的120摄氏度。宇航员的太空服是白色的,在他们漂浮在地球上方时白色服装可以反射光热。
A year on Venus is shorter than a day there.
金星的一年比一天短。
Venus spins very slowly in the opposite direction of Earth — 243 Earth days for a full rotation. But it only takes 225 days to go around the sun because it's so close to it. Therefore, a year on Venus is shorter than a day.
金星自转速度很慢,而且和地球自转方向相反。金星绕太阳公转一周仅需225个地球日,因为金星离太阳很近,但金星自转一周却需要243个地球日。因此,金星的一年比一天短。
The International Space Station (ISS) is the size of a football field.
