Recent data indicate one or more moderately nearby supernovae in the Early Pleistocene, with additional events likely in the Miocene. This has motivated more detailed computations, using new information about the nature of supernovae and the distances of these events to describe in more detail the sorts of effects that are indicated at the Earth. This short communication/review is designed to describe some of these effects so that they may possibly be related to changes in the biota around these times.

中等附近超新星的地球效应

最近的数据表明，早更新世有一颗或多颗中等附近的超新星，中新世可能还有其他事件。这激发了更详细的计算，使用有关超新星性质和这些事件距离的新信息来更详细地描述在地球上显示的各种影响。这个简短的交流/评论旨在描述其中一些影响，以便它们可能与这些时期生物群的变化有关。
