Over 400 light-years away, at the edge of a molecular cloud , both star and nebula are seen to vary significantly in brightness but not necessarily at the same time, adding to the mystery of the intriguing region. T Tauri stars are now generally recognized as young -- less than a few million years old -- sun-like stars still in the early stages of formation .

它们的 观测亮度会有大幅度的变化，不过不一定会同步，而这也是此区域的谜团之一。T型变星通常是年龄不到数百万年的年轻类太阳恒星，还处在恒星形成的初期阶段。

Astronomers John Carr of the Naval Research Laboratory in Washington, D.C., and Joan Najita of the National Optical Astronomy Observatory in Tucson, Arizona, used Spitzer to tease out the signals revealing the molecular composition of the gas in the disk surrounding AA Tauri, a star less than a million years old located in the constellation Taurus.

华盛顿哥伦比亚特区海军研究实验室的天文学家约翰·卡尔，和亚利桑那州图森国家光学天文台的天文学家琼·纳吉塔，利用斯必泽太空望远镜挑选出能够揭示恒星" AA 托莱"周围圆盘中气体分子构成情况的信号。恒星" AA 托莱"位于金牛座，诞生于不到一百万年前。

We figure out the telescope mount parameters by observing stars with CCD, and establish a measurement system, including CCD and image acquisition card to collect stars'image data, time and frequency system (made up of high accuracy counter, the GPS second signal and 10MHz frequency standard), the observing software in VC++6.0 for collecting and processing star image and the image processing software programmed with MATLAB.

建立了一套用于测定望远镜机架指向误差模型参数的系统，包括：CCD 及图像卡等硬件系统用于采集恒星图像数据；使用高精度的计数器、GPS 提供的秒信号和标准10MHz信号开发了用于观测软件的时间频率系统；使用VC++6.0 编制了包括用于计算恒星位置及图像采集和处理的观测程序，并用MATLAB编制了用于处理观测数据的程序。

Light from ordinary stars and galaxies comes largely from atoms powered by thermonuclear reactions in the hearts of stars.

来自一般恒星和星系的光，主要是那些受恒星内部的热核反应所激发的原子发射出的。

Four stars collectively called the Trapezium form the center of the nebula, which to our eye looks like the brightest star in the sword of Orion.

四个恒星构成了猎户座星云的中心，在我们看来，这就好像是"猎户座之剑"最明亮的恒星。

Starcat - Starcat is a cross-platform star catalog visualization tool for use with the Bright Star, Hipparcos, and Tycho star catalogs.

starcat是一个跨平台的恒星目录可视化工具，用于和Bright Star， Hipparcos，和 Tycho恒星目录一起工作。

Here we report Li abundances for an unbiased sample of solar-analogue stars with and without detected planets.

我们的报告中有关锂丰度的样本真实可靠，样本中既含有"有行星"恒星同时具有"无行星"恒星。

The star points to paths in which we can advance the stellar science, but ones that are still covered by underbrush.

这颗恒星为我们指出了进一步研究恒星的道路，同时这也是一条布满荆棘的道路。
