Michaela Musilova: 作为一名模拟宇航员,我主要在模拟月球或火星的环境中生活和工作,为未来人类的长期任务做准备。在这些模拟任务中,我们会被限制在偏远地区的小型站点中,面临水、食物等资源的限制,外出时必须穿宇航服并获得任务控制中心的许可。K2-18b是一颗位于宜居带的系外行星,这意味着它与恒星的距离允许水以液态形式存在于行星表面。最近的研究表明,K2-18b的大气层中可能存在生物特征,这暗示着那里可能存在生命。然而,其他研究人员对此表示怀疑,认为该行星离恒星太近,不可能有海洋存在。尽管如此,詹姆斯·韦伯太空望远镜在搜寻生命方面发挥了重要作用,它使我们能够更详细地观察系外行星的大气层,寻找氧气和其他生物特征。但我们也要意识到,即使探测到外星生命,也需要经过不同团队的验证才能确认,以避免数据偏差和技术错误。此外,政治因素也可能影响科学研究的进展,例如特朗普总统提议削减NASA的资金,这可能会限制望远镜的使用时间和影响未来的探测任务。

Shownotes Transcript

Today we’re ditching the drama on Earth and talking about K2-18b, an exoplanet 120 light-years away. K2-18b recently made headlines after researchers claimed to observe possible “signs of life” in the planet's atmosphere. So, did we find aliens? Michaela Musilova, an astrobiologist and analog astronaut, said it’s too early to tell. On the show today, Musilova breaks down the debate over K2-18b, why better telescopes are needed to find definitive proof of life on another planet, and why President Trump’s proposed funding cuts to NASA could disrupt this search. Plus, what’s it like to be an analog astronaut, and what do they actually do?

Then, why a healthy reading diet contains both “broccoli” and “chocolate pie” books. And, Jessamine Chan, author of “The School for Good Mothers,” answers the Make Me Smart question.

Here’s everything we talked about today:

"Republican Tax Plan Boosts SALT Deduction, Ends Green-Energy Breaks") from The Wall Street Journal
