Nebulae usually consist of Hydrogen and Helium, as these are the most common and stable compounds in theUniverse. The formation of a nebula can occur when a star undergoes a significant change, such as excess fusion in its core. In the case of a planetary nebula, the formation of this dee...
Ney-Allen infrared nebulasilicate featurewarm dustDiffraction-limited array images of the Trapezium/Ney Allen infrared nebula have been obtained at six wavelengths between 7.8 and 12.4 microns, including the 9.7 micron silicate feature. Extended emission from warm dust shows significant differences in ...
“This is the youngest one I know of, ” he says. The colorful cloud in the image is only a few thousand years old. “Now the nebula is hugging the star, ” he says. But as time flies by, it will bloom outward in expanding shells or rings of gas and dust. Astrophysicists ...

Though it is true that many animals are strictly associated with certain plants, it is misleading to speak of a "spruce-moose biome," for example, because there is no internal cohesion to their association as in an organism. 问题 句子分析(俗称“长难句分析”)是训练提高基础阅读能力的有效手段...
