天文学家绘制星际冰地图

2025-04-16 18:37 by 苏珊娜之歌

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。

NEWS: Telegram supports Facetime video calls NOW!

Secure video calling is in high demand. As an alternative to Zoom, many people are using end-to-end encrypted apps such as WhatsApp, FaceTime or Signal to speak to friends and family face-to-face since coronavirus lockdowns started to take place across the world. There’s another option—secure communications app Telegram just added video calling to its feature set, available on both iOS and Android. The new feature is also super secure—like Signal and WhatsApp and unlike Zoom (yet), video calls will be end-to-end encrypted.

The STAR Market, as is implied by the name, is heavily geared toward smaller innovative tech companies, in particular those engaged in strategically important fields, such as biopharmaceuticals, 5G technology, semiconductors, and new energy. The STAR Market currently has 340 listed securities. The STAR Market is seen as important for China’s high-tech and emerging industries, providing a space for smaller companies to raise capital in China. This is especially significant for technology companies that may be viewed with suspicion on overseas stock exchanges.
