Some places on Earth are extreme: the North and South Poles with their freezing temperatures, the deep sea where sunlight cannot reach, and the inside of fiery hot volcanoes. But none of these regions come close to comparing to the harsh conditions found on some other planets in the Universe.
For example, using an X-ray space telescope called Chandra, astronomers have recently found a distant planet that is being blasted with X-ray radiation from the star that it orbits. This X-ray radiation is 100,000 times more intense than what the Earth gets from its nearest star, the Sun!
