Sheltered from the blazing summer sun, a group of scientists in the northern Italian city of Padua spent weeks in a laboratory finalising an instrument they say could transform the study of the solar corona, the outer layer of the sun's atmosphere.
As a total solar eclipse sweeps across Europe on August 12, the Circular Slit Spectrometer (CISS) will undergo a decisive test at Spain's Javalambre Astrophysical Observatory, where researchers hope to prove it can break down the Sun's light into its constituent wavelengths much faster than existing instruments.
意大利北部城市帕多瓦的一群科学家躲避着炎炎烈日，在实验室里花了数周时间完善一件仪器——他们说，这件仪器可能改变太阳日冕（太阳大气最外层）的研究方式。
8 月 12 日日全食掠过欧洲上空时，环形狭缝光谱仪（CISS）将在西班牙哈瓦兰布雷天体物理天文台接受决定性测试，研究人员希望借此证明它能比现有仪器快得多地将太阳光分解为各组成波长。
