天文学家首度利用韦伯太空望远镜，针对蝘蜓座 I 分子云（Chamaeleon I molecular cloud）绘制出三种星际冰（水、二氧化碳、一氧化碳）的分布图，深入解析恒星诞生前的化学环境。这项研究不仅提升了空间解析度，也大幅增加样本数量，为理解恒星与行星的形成提供了关键新线索。在宇宙中寒冷的分子云中，这些充满气体与尘埃的区域正是恒星诞生的摇篮。微小的尘埃粒子常被一层层冰所覆盖，这些冰包含水、二氧化碳与一氧化碳等简单分子，是恒星与行星诞生过程中不可或缺的原料。如今，天文学家首次成功绘制出这些冰在整个分子云中的分布图，为我们提供了一扇前所未有的窗口，得以一窥恒星诞生之前的化学环境。

A leaked Telegram discussion by 50 so-called crypto influencers has exposed the extraordinary steps they take in order to profit on the back off unsuspecting defi investors. According to a leaked screenshot of the chat, an elaborate plan to defraud defi investors using the worthless “$Few” tokens had been hatched. $Few tokens would be airdropped to some of the influencers who in turn promoted these to unsuspecting followers on Twitter.
If riding a bucking bronco is your idea of fun, you’re going to love what the stock market has in store. Consider this past week’s ride a preview.The week’s action didn’t look like much, if you didn’t know better. The Dow Jones Industrial Average rose 213.12 points or 0.6%, while the S&P 500 advanced 0.5%, and the Nasdaq Composite ended little changed.
