In 2018, images were released of a planet being formed around the star PDS 70, offering a tantalizing glimpse into how planets come into being. However, many questions remain about how dust evolves into planets, and astrophysical observations are unable to provide all the answers. It is therefore necessary to perform experiments to reveal key details and, to avoid unwanted effects from the Earth’s gravitational pull, it is often necessary to perform such experiments in microgravity platforms. This Review sketches current models of planet formation and describes the experiments needed to test the models.

使用微重力实验了解行星的形成

2018年,发布了行星PDS 70周围形成一颗行星的图像,使人们对行星的诞生产生了令人着迷的印象。但是,关于尘埃如何演变成行星,仍然存在许多问题,天体物理学的观测无法提供所有答案。因此,有必要进行实验以揭示关键细节,并且为了避免来自地球引力的不良影响,通常有必要在微重力平台上进行此类实验。本评论概述了行星形成的当前模型,并描述了测试模型所需的实验。
