L55-1: From the earth: Greetings
Recent developments in astronomy have made it possible to detect planets in our own Milky Way银河 and in other galaxies. This is a major achievement because, in relative terms, planets are very small and do not emit light. Finding planets is proving hard enough, but finding life on them will prove infinitely more difficult. The first question to answer is whether a planet can actually support life. In our own solar system, for example, Venus is far too hot and Mars is far too cold to support life. Only the Earth provides ideal conditions, and even here it has taken more than 4 billion years for plant and animal life to evolve. Whether a planet can support life depends on the size and brightness of its star, that is its 'sun'. Imagine a star up to 20 times larger, brighter and hotter than our own sun. A planet would have to be a very long way from it to be capable of supporting life.
