Galaxy, while globular clusters and other extreme Population II objects have scale heights of thousands of parsecs, indicating little or no concentration at the plane. Such data and the variation of star density withzdistance bear on the mixture of stellarorbittypes. They show the range from ...
Earth is located roughly halfway to the edge of the Milky Way, at a distance of about 26,000 light years from the center. We reside in a feature known as the Orion Spur (sometimes also called the Orion Arm), which is an offshoot between the larger Sagittarius and Perseus Arms that lie...
observations of these masers have proved that our Milky Way is a magnificent example of a spiral galaxy. Astronomers have observed that our galaxy has four large-scale arms. But there’s also a fifth arm, not as large or obvious, that tracks less than a quarter of the way around...

the understanding of the galaxy's shape had been based upon indirect measurements of celestial landmarks within the Milky Way and inferences from structures observed in other galaxies populating the universe.The new map was formulated using precise measurements of the distance from the sun to 2,400...
(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.”第四段“Previously, astronomers saw evidence of hydrogen clouds becoming warped(弯曲的)in the Milky Way”...

It was long thought that the Milky Way was located at the center of the Universe. Initially, this was likely due to hubris. But, later, it seemed that every direction we looked everything was moving away from us and we could see the same distance in every direction. This led to the ...
The ACS imaging shows a large spheroidal object with a central surface brightness mu(475) = 25.8 mag arcsec(-2), a Sersic index n = 0.6, and an effective radius of 7 '', corresponding to 3.4 kpc at the distance of Coma. The galaxy is not resolved into stars, consistent with ...
