probably even fewer that have two giant planets.

In addition to giant Jupiter and lesser giant Saturn, we have tiny Mercury—just a bit bigger than Earth\'s moon.

So if we\'re weird, what does a typical solar system look like? Weiss and her team trained their

telescopes on 355 star systems known to host a handful of small exoplanets（外行星）. And they found

that most of the planets within individual star systems tended to be similar in size.

over, is also likely to be two times the size of Earth, give or take a little bit.And they were strung out at similar distances from each other too...like peas in a pod, she

Because there might just be a few more peas in the pod.

这里是科学美国人——60秒科学。我是克里斯托弗·因塔利亚塔。 天文学家对宇宙的研究越多就越意识到：我们的太阳系非常奇怪。

“有几件事让太阳系变得有些奇怪。”蒙特利尔大学的天体物理学家劳伦·韦斯说道。“其一，太阳系有一颗巨行星。在类似太阳的恒星中，只有约10%拥有巨行星。”拥有两颗巨行星的恒星可能更少。

除了巨大的木星和较小一些的土星之外，太阳系还有小型行星水星——其体积只比月亮稍大一些。 因此，如果我们的太阳系很奇怪，那典型的太阳系是什么样的呢？韦斯和团队用望远镜观察了355个星系，这些是已知拥有少量小型系外行星的星系。他们发现，独立星系中大多数行星的体积大小往往很相似。

“所以，如果我是一颗行星，体积是地球的两倍，那我旁边行星的体积很可能也是地球的两倍，误差只有一点儿。”

她说，这些行星排成一排，彼此之间的距离也相似，就像豆荚中的豌豆一样。与那种有序排列相比，我们的太阳系看起来更像是……“嗯，让我想想，如果用食物来形容……我不知道……可能就像完整的感恩节晚餐之类的吧？” 这项研究结果发表在《天文学期刊》上。

至于寻找宜居世界：“如果我们试图在宜居地带寻找地球大小的行星”，既不会离恒星太近也不会离得太远，“然后我们发现了与地球大小接近的行星，那可能继续搜寻其周围的行星是值得的。”

因为“豆荚”中可能有更多的“豌豆”。

This is Scientific American — 60-Second Science. I\'m Karen Hopkin. Are you one of those people who can tell when

a storm is approaching based on your achy knees? Well, you may think you are. But a new study of more than 1.5 million seniors finds no relationship between rainfall and doctor visits for pain. The results are in the British Medical Journal.

The idea that our bodies are barometers for all sorts of weather-related phenomena—including changes in temperature, pressure and precipitation—is not a new one.

hat things like

rainfall influence symptoms of joint pain and stiffness. But if you look at the studies there\'s

actually been surprisingly little evidence to suggest that is true. Most of the studies have been

quite small. And we were interested in thinking about whether we could approach this question in a \'big data\' sort of way.

He and his colleagues looked at information collected in more than 11 million visits that older

Americans made to their primary care physicians. They compared these records with data on

daily rainfall. And they asked: do more people report sore backs or swollen joints when the weather is inclement?
