Astronomers don't know if these same life-generating processes are taking place around stars that are cooler than our sun, but the Spitzer observations show their disk chemistry is different.

天文学家不知道同样的生命产生进程会不会在那些比我们太阳更冷的恒星周围发生，但斯皮策观测站发现他们的尘埃盘的化学特性是不同的。

By comparison, meteors of the type that hit Russia originate at the earliest reaches of time in the disk of gas and dust that swirled around the early sun.
