NASA即将发射南西·葛蕾丝·罗曼太空望远镜，旨在探索占据宇宙大部分的暗物质与暗能量。这台望远镜拥有与哈伯相当的解析度及极其广阔的视野，将绘制宇宙大尺度结构的详细地图，帮助科学家深刻理解宇宙的演化过程。

罗曼望远镜还将透过微引力透镜等先进技术，寻找多达数十万颗新系外行星。它能探测到质量极小的行星甚至是孤立的流浪行星，这些重要发现将有助于我们了解行星系统的形成机制，并评估类似地球的生命孕育环境在宇宙中是否罕见。

此外，该太空望远镜将观测超过十亿个星系及大量超新星爆发，以检视当前宇宙学标准模型的诸多未解之谜。透过更精确地测量宇宙膨胀速度与物质分布状态，科学家有望厘清暗能量的潜在变化，从而带来宇宙学领域的重大突破。

NASA is soon launching the Nancy Grace Roman Space Telescope to explore dark matter and dark energy, which make up most of the universe. With a resolution matching Hubble and an extremely massive field of view, it will map the large-scale structure of the cosmos in detail to help scientists deeply understand cosmic evolution.

The Roman telescope will also search for hundreds of thousands of new exoplanets using advanced techniques like microlensing. It can detect extremely low-mass planets and even isolated rogue planets, and these important discoveries will help us understand the formation mechanisms of planetary systems and assess whether life-bearing environments like Earth are rare in the universe.

Furthermore, the space telescope will observe over a billion galaxies and numerous supernova explosions to investigate several unsolved mysteries in the current standard model of cosmology. By more precisely measuring the universe's expansion rate and the state of matter distribution, scientists hope to clarify the potential changes in dark energy, thereby bringing about major breakthroughs in the field of cosmology.
