苹果首款折叠 iPhone Duo 双页 PDF 模式曝光

2026年10月，天文学家利用韦布空间望远镜和斯皮策望远镜的历史数据，研究年轻恒星周围异常富含温暖尘埃的碎屑盘，希望寻找岩质天体剧烈碰撞留下的线索。团队汇集21个系统进行分析，把尘埃的矿物组成、颗粒大小和亮度变化联系起来，比较这些环境的形成过程。

研究发现，这类极端碎屑盘通常含有较小颗粒、大量温暖尘埃，并呈现不规则的亮度变化。通过中红外光谱，团队进一步将样本分为富含二氧化硅和相对缺少二氧化硅两类，用于判断产生碎屑的碰撞可能具有怎样的条件。类似研究有助于理解年轻行星系统中物质如何重新分配，也为讨论早期地球与月球形成所涉及的撞击提供参照。不过，望远镜观测到的是尘埃和辐射留下的结果，并非直接拍摄到行星相撞。不同矿物特征需要结合模型解释，团队也将继续通过更多样本检验这些特殊碎屑盘为何较少被发现。
