Collisions also can transform theshapeof galaxies involved; specifically, the merger of two spiral galaxies may produce a singleellipticalgalaxy. 碰撞也会改变星系的外形,特别是当两螺旋星系融合后可能会产生单一的椭圆星系。 With its originalellipticalhands this clock changesshapelike a satellite changes orbi...
题目Which galaxy has a spiral shape? A. Milky Way B. Andromeda Galaxy C. Elliptical galaxy D. Irregular galaxy 相关知识点: 试题来源: 解析 A。解析:银河系(Milky Way)是螺旋状星系。选项 B 仙女座星系也是螺旋星系,但本题问的是哪个星系有螺旋形状,首先想到的通常是我们所在的银河系。选项 C 椭圆...
By modelling the axis ratio distribution of SDSS DR8 galaxies we find the intrinsic 3D shapes of spirals and ellipticals. We use morphological information from the Galaxy Zoo project and assume a non-parametric distribution intrinsic of shapes, while tak
Erratum: The intrinsic shape of galaxies in SDSS/Galaxy Zoo. We measure the effect of the environment on the intrinsic shapes of spiral\nand elliptical galaxies by finding the 3D shape distribution and dust\nextinction that fits better the projected shape of galaxies in different\nenvironment. We...
In order todetermine the probability density function (PDF) of \\eta_{0}, we consider theangular diameter distances from galaxy clusters recently studied by twodifferent groups by assuming elliptical (isothermal) and spherical(non-isothermal) $\\beta$ models. The strict validity of the DD ...
“This loss of gas causes them to ‘drop’ their spiral arms, transforming into a lenticular shape.” “Another cause is galaxy mergers, which can see two or more spiral galaxies crashing together to form one large elliptical galaxy in the aftermath.” ...
For example, our Sun is only one of the hundreds of billions of stars in our Milky Way galaxy. All the galaxies in our universe come in one of three different main forms known as spiral, elliptical, and irregular galaxies.Answer and Explanation: ...

great distances,however,billions of other galaxies are scattered.These galaxies are of many shapes and sizes.The Milky Way Galaxy is shaped like a spiral(螺旋型)disk.Other galaxies have been found to be shaped like spirals,too.In addition,still other galaxies are elliptical or irregular in ...
