Launched nearly 15 years ago on August 25, 2003, the Spitzer Space Telescope is the final mission in NASA’s Great Observatories Program – a family of four space-based observatories, each observing the universe in a different kind of light. The other missions in the program include the visible-light Hubble Space Telescope, Compton Gamma-Ray Observatory, and the Chandra X-Ray Observatory.

Spitzer太空望远镜于大约15年前的2003年08月25日发射升空,这是NASA伟大天文台计划的最后一个任务,这个任务的大家庭包含4个太空望远镜,每个观测站以不同的波段观测着宇宙。该计划中的其他成员包括:工作在可见光波段的哈勃太空望远镜,Compton伽玛射线天文台以及Chandra X 射线天文台。

A Slice of Glory (一片壮丽)

If you have ever seen a series of concentric rings of color near a mist or fog, you have likely seen a glory. This colorful optical phenomenon, bright red on the outside and blue toward the center, forms when water droplets scatter sunlight back toward a source of light.

NASA: ‘X’-ploring the Eagle Nebula and ‘Pillars of Creation’(’X射线’-探索巨蛇座鹰状星云和"创造之柱")

This new composite image shows the region around the Pillars, which are about 5,700 light years from Earth. The image combines X-ray data from NASA’s Chandra X-ray Observatory and Hubble Space Telescope optical data. The optical image, taken with filters to emphasize the interstellar gas and dust, shows dusty brown nebula immersed in a blue-green haze, and a few stars that appear as pink dots in the image. The Chandra data reveal X-rays from hot outer atmospheres from stars. In this image, low, medium, and high-energy X-rays detected by Chandra have been colored red, green, and blue.
