The most obvious astronomical object in the sky, our Sun, is a typical star. At night most of what we see in the sky is other stars, bodies much like our Sun except that they come in a wide variety of sizes, surface temperatures, distance, etc. For much of the past century, many astronomers have been actively trying to obtain information about individual stars (such as how much mass each has), to understand what stars are like below their glowing surfaces (How hot and how dense is the interior? Is the material gaseous?), and particularly to understand how stars form and change, and eventually collapse to huge hot cinders.

天空中最明显的天体，我们的太阳，是一颗典型的星星。在晚上，我们在天空中看到的大多数是其他恒星，这些恒星与我们的太阳非常相似，只是它们的大小、表面温度、距离等各不相同。在过去的世纪的大部分时间里，许多天文学家一直在积极地试图获得有关单个恒星的信息（比如每颗恒星有多少质量），了解恒星在发光表面下的样子（内部有多热，密度有多大？物质是气态的吗？），特别是了解恒星如何形成和变化，并最终坍缩成巨大的热煤渣。
