大螺旋星系m 81最近给力的“借火”将这个又被称为M82的不规则的星系唤起。
M82, as this irregular galaxy is also known, was stirred up by a recent pass near large spiral galaxy M81.
这个美丽的螺旋状星系位于孔雀星座以南，它看起来完全就是我们的银河系的翻版，但却有它的两倍大。
The beautiful spiral galaxy, located in the southern constellation Pavo (the Peacock), is a virtual copy of our own Milky Way, though about twice as big.
银河系可说是我们周遭大质量螺旋星系的典型，根据观测到的大质量恒星数目判断，银河系的恒星形成率为每年数个太阳质量。
In our own Milky Way, which is quite typical of nearby, massive spiral galaxies, the number of observed high-mass stars indicates that stars are forming at a rate of a few solar masses a year.
