The Nancy Grace Roman Space Telescope launches to study dark matter and dark energy

南希·格雷斯·罗曼太空望远镜发射升空,旨在研究暗物质与暗能量

After funding struggles and a name change, the Nancy Grace Roman Space Telescope has been successfully launched. It will now make a three-month, one-million-mile journey to its orbit at the second Sun-Earth Lagrange point (L2) beyond the Moon. 在经历资金困境和更名风波后,南希·格雷斯·罗曼太空望远镜(Nancy Grace Roman Space Telescope)已成功发射。它现在将开启一段为期三个月、长达一百万英里的旅程,前往位于月球轨道之外的日地拉格朗日第二点(L2)轨道。

From this vantage point, Roman will conduct an unprecedented survey of the universe. Its field of view is 100 times larger than Hubble’s and, according to NASA, it can survey the sky 1,000 times faster using its 300-megapixel infrared camera. Roman also has a Coronagraph system that can block and mask glare from stars, allowing it to directly image exoplanets, even smaller, older, and colder planets orbiting close to their stars. 从这一有利位置出发,罗曼望远镜将对宇宙进行前所未有的巡天观测。其视场是哈勃望远镜的100倍;据NASA称,凭借其3亿像素的红外相机,它观测天空的速度将比哈勃快1000倍。罗曼望远镜还配备了日冕仪系统,可以阻挡和遮蔽恒星的强光,从而直接拍摄系外行星,甚至包括那些体积更小、年龄更老、温度更低且靠近其母恒星运行的行星。

Roman will also conduct detailed 3D scans to help map the distribution of dark matter and narrow down the potential candidates for its makeup. Using the same 3D scans and gravitational lensing measurements, Roman will attempt to map how dark energy shaped the evolution of the universe. 罗曼望远镜还将进行详细的3D扫描,以帮助绘制暗物质的分布图,并缩小其构成成分的潜在候选范围。通过同样的3D扫描和引力透镜测量,罗曼望远镜将尝试描绘暗能量是如何塑造宇宙演化的。

Nicky Fox, associate administrator for the Science Mission Directorate at NASA, said in a press release that “Roman will be a discovery machine that will bring us closer than ever before to answering humanity’s most profound questions about our cosmic history.” NASA科学任务理事会副局长尼基·福克斯(Nicky Fox)在新闻稿中表示:“罗曼望远镜将成为一台发现机器,它将使我们比以往任何时候都更接近于回答人类关于宇宙历史最深奥的问题。”
