A new Mosaic from NASA's newest infrared observatory captures the heart and Soul nebulae, so named because of their resemblance to hearts -both the Hallmark-card and the blood-pumping variety.

这是一张最新的来自美国宇航局的红外观测站捕捉拍摄到的花叶状的心和灵魂星云，这样命名是因为他们的形状就同贺曼贺卡上画的心，以及血泵功能的心脏及其相似。

Herschel's cryostat approach to cooling was evolved from a previous Esa mission - the Infrared Space Observatory (ISO), which operated in the 1990s.

BBC: Herschel space telescope finishes mission

Many Americans recognize the unsurpassed science and inspiration that have come from the Hubble Space Telescope over the past two decades, as well as from its less famous sister satellites like the Chandra X-ray Observatory, the Spitzer Space (Infrared) Telescope and the Fermi gamma-ray observatory.

The US space agency observatory is well suited to picking up the infrared signal expected from cold grains of dust about 10 microns (millionths of a metre) in size.
