High-resolution surveys chart the spiral structure of the galaxy and the location of our solar system
先看前文a new 3D map reveals a surprise,可见填补句,突出的特点是surprise(令人惊奇的),然后再看后几段内容的提示,第二段“The Milky Way is a spiral(漩涡型的) galaxy, in which stars and gas clouds exist mainly in its spiral “arms”第三段“Using 1,339 large, pulsating(脉冲的) stars to ...
A probabilistic new map of the universe surrounding the Milky Way reveals that our galaxy is likely part of an even larger "basin of attraction" than we previously assumed.When you purchase through links on our site, we may earn an affiliate ...

cloud complexes in Orion and Taurus, obtained with the CfA 1.2 m telescope, have been combined with 31 other surveys obtained over the past two decades with that instrument and a similar telescope on Cerro Tololo in Chile, to produce a new composite CO survey of the entire Milky Way. The...
Using 1,339 large, pulsating(脉冲的) stars to make a 3D map of the Milky Way, researchers discovered instead that the galaxy’s disk of stars is increasingly twisting,most likely due to the spinning of the disk. And the farther the stars are from the center, the more twisted it becomes...
Inspection of the VVV images and PSF photometry reveals that most of these stars are likely to belong to a globular cluster, that matches the position of the previously known star cluster FSR 1716. The stellar density map of the field yields a > 100 sigma detection for this candidate ...
Gaia is designed to draw a map of the Milky Way, our home galaxy. Just as a map of your town gives you a picture of where things are located, Gaia’s map of the galaxy will tell astronomers where the stars are. Over five years, Gaia will observe (观察) about a billion stars and...

We derive a radialvelocity, and velocity dispersion map of the Milky Way bulge, useful to becompared with similar maps of external bulges, and to infer the expectedvelocities and dispersion at any line of sight. The K-type giants kinematics isconsistent with the cylindrical rotation pattern of...
