【我的总结与翻译】

"Large (spiral) galaxies like the Milky Way seem to have 2 or 3 per century. But it's clear we have not been getting our share. A half dozen or so have been reported over the last millennium, but (there) should be 20 or 30. Now the galaxy is full of gas and dust, which could hide (a) distant supernova optically, but the remnant would still produce detectable radio (waves and X-rays). This (lack) is a significant puzzle."

"像银河系这类螺旋状大星系每世纪似乎都会有2、3个超新星。但事实上我们都还没有发现。在过去的1000年里，据报告的有六颗，但应该有20至30颗的。现在，星系充满了气体和尘埃，它们可能挡住了遥远的可视的超新星，但它的残骸仍然放射出可以探测到的无线电和X射线。超新星没有完全被发现至今仍是一个重要的未解之迷。"

The discovery of the young remnant does not immediately provide an answer to the puzzle, but scientists say it will be a "goldmine" to study, since it is still so recent and energetic. They say it is an important finding for understanding the life cycles of stars in the Milky Way galaxy.

年轻超新星残骸的发现并没有立即解开这个谜团，但科学家认为，它将是个可供研究的宝藏，因为它的时间如此的近且充满活力。他们指出，它对于弄明白银河系恒星的生命周期非常重要。

Bob (Kirshner), of Harvard University, explains why surpernovae are important for all of us.

哈佛大学的Bob Kirshner阐明了超新星对我们很重要的原因。

"The supernovae make the chemical elements through real alchemy, transforming one element, the (light) elements into the heavy ones. So the calcium that is in your bones and (the) iron that is in your blood (probably) came from supernovae that exploded before the sun formed. So, we (are) all (stardust), and it seems reasonable for us to want to know how these elements get formed when stars explode."

“超新星是通过真正炼金术而形成的化学元素，它将一种元素、轻的元素转变成重的。所以，你骨头中的钙及血液中的铁很可能来源于太阳形成之前爆炸的超新星。因此，我们都是星尘，我们想知道在恒星爆炸时这些元素是如何形成，这很合理。”
