恒星

Some of its brighter stars have been used as standard candles to establish important estimates of extragalactic distances and the scale of the Universe.

一些它的较明亮的恒星发出的光已经被用作标准光谱分析去建立银河系外星系距离的重要估算和宇宙的度量。

The heretofore unexpected extent of dust beyond the starry limits of the arms, shows new areas for extragalactic astronomical study.

这个在充满恒星的旋臂之外出现的巨大的尘埃云团完全出乎科学家的预料，为银河系外的天文学研究提供的新的课题。

HD 189733b is one of more than 270 planets to be discovered orbiting stars other than our sun, called extrasolar planets.

HD 189733b 是业已发现的270多颗围绕着太阳系以外恒星旋转的行星之一，被称为系外行星。

The new star has only about seven percent of the mass of the Sun, and it is 300,000 times fainter.

这颗恒星的质量大约只有太阳的70%，但是她却比太阳暗300，000倍。

Stars with less mass than the sun are smaller and cooler, and hence much fainter in visible light.

质量比太阳小的恒星会比较小和比较冷，几乎不产生可见光。

In this image, taken by the Hubble Space Telescope, new stars can been seen inside fingerlike protrusions extending from the top of the nebula.

在这张图像上，运用的哈勃太空望远镜，新的恒星被认为是里面指状的突出延伸，从最高层的星云中。

"This is an important discovery as it is the first time glycolaldehyde , a basic sugar, has been detected towards a star-forming region where planets that could potentially harbor life may exist," said researcher Serena Viti of the University College London.

&这是一项重要的发现，因为这是首次在恒星形成的区域内发现基本糖类乙醇醛，这个区域可能存在拥有生命的行星，&伦敦大学学院的研究人员塞雷纳·维蒂说。

An international team of scientists used the IRAM radio telescope in France to detect glycolaldehyde in a massive star-forming region of space, some 26,000 light-years from Earth.

一组跨国科学家，利用法国毫米电波天文研究所的射电望远镜，在太空一个大规模的恒星形成区发现了乙醇醛，该区距离地球大约2.6万光年。

The horse's gaze seems fixed on Beta Scorpii, also named Graffias, the bright star at the lower left.

这匹马的目光似乎固定在Beta Scorpii（也称为Graffias），是左下角那颗明亮的恒星。

With a comprehensive analysis of the astronomical work Huan Yu Shu Yao witten byr Ma Dexin (1794-1874), a Qing minority nationality scholar who had shdied adroad, this Paper holds that the work has some distinguishing features in the research of the Hui calendar, introduction of Galileo's heliocentric theory, and observation of stars and planets. It also makes imortant achievements in drawing charts of the heliographic distributon of sunspots, the surface of the moon and the surfaces of the five big p...

该文全面剖析了我国近代最早出洋的科学家马德新的天文学著作《寰宇述要》，指出这部著作在对回回历法的研究、哥白尼学说的介绍、恒星行星观测以及太阳黑子分布图、月面图、五大行星表面图的绘制等方面均具有特色，在我国天文学史上占有一定的地位，是一部有广泛影响的我国少数民族科学家的天文学专著。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
