- Also called 30 Doradus, the red and pink gas indicates a massive emission nebula, although supernova remnants and dark nebula also exist there. 该星云还被称为剑鱼座30,红色和粉色气体代表了大质量发射星云,尽管那里还存在着超新星和黑暗星云。
- The greater Eagle emission nebula, tagged M16, lies about 6500 light years away, spans about 20 light-years, and is visible with binoculars toward the constellation of Serpens. 老鹰星云及其周围的发射星云合称为M16,大小约为20光年,距离我们约有6500光年远,用双筒望远镜可在北天的巨蛇座内找到它。
- Other types of nebulas visible here include red emission nebula and the blue reflection nebula. 在这里还能看到其它星云,包括红色的发射星云和蓝色的反射星云。
- Celbi WORK PERFORMED: Semestral analysis of compliance of gaseous emissions and calibration of on-line analyzers, PORTUGAL. Celbi所做工作业绩:在葡萄牙,负责对废气的一致性进行分析,以及对在线联机分析器的标定。
- The contaction of the gas with a reactive solid is one of the large classes of processes for controlling gaseous emissions into the atmosphere. 利用气体与反应性固体的接触是控制气体散发到大气中的众多工艺过程之一。
- Like other stellar nurseries, the Cocoon Nebula holds, at the same time, a bright red emission nebula, blue reflection nebulas, and dark absorption nebulas. 就像其它恒星孕育场一样,茧状星云同时具有明亮的红色发射星云,蓝色的反射星云以及黑暗的吸收星云的角色。
- Plutarch's careful observations and reporting of data about the gaseous emissions at Delphi show that the ancients did not try to exclude scientific inquiry from religious understanding. 普鲁塔克仔细观察、记录了德尔菲气体冒出的现象,显示老祖宗并不打算为了宗教上的领悟而排除科学的求知精神。
- The Trifid, also known as M20, is only about 300,000 years old, making it among the youngest emission nebulae known. 三裂星云也被称为M20,年龄只有30万年,这让它成为迄今为止最年轻的发射星云。
- Possibly not, but that is where two bright emission nebulas nicknamed Heart and Soul can be found. 可能不是,但暱称为心藏与魂魄星云的明亮发射星云倒都在仙后座内。
- Numerous red emission nebulas and blue reflection nebulas are visible throughout the image. 在整张影像中,许多红色发射星云和蓝色反射星云清晰可见。
- Most emission nebulae are about 90% hydrogen, with the remainder helium, oxygen, nitrogen, and other elements. 大部分的发射星云都有90%25的氢,其馀的部份则是氦、氧、氮和其他的元素。
- Just as large star forming regions create emission nebulae in the LMC, NGC 55 is also seen to be producing new stars. 大麦哲伦星系的大面积恒星诞生区产生发射星云,NGC 55同样有新的恒星。
- The ball is filled with gaseous mixture. 那个球充满了气体混合物。
- Emission nebulae often have dark spots in them which result from clouds of dust which block the light. 发射星云经常会有黑斑出现,这是云气中的尘埃阻挡了光线造成的。
