What are the space stations equipped with to observe distant stars and galaxies? A. Microscopes. B. Cameras. C. Advanced telescopes. D. Binoculars. 相关知识点: 试题来源: 解析 C。解析:“The space station is also equipped with advanced telescopes to observe distant stars and galaxies.”。
The majority of bright early-type galaxies in this field are found at redshifts $z \\leq 1.3$ to share common properties with those of high-z cluster samples, as for the age and mass of the dominant stellar population -- which are found to be as old as 3-5 Gyr and as massive as...
Well, basically it refers to the number of galaxies there are within a cluster. FEMALE STUDENT: Is that the same as density? MALE PROFESSOR: That’s right.Both, uh, “richness” and “density” refer to the number per area.Rich clusters, or dense clusters, uh, contain a relatively high...
1. Spiral Galaxies The most beautiful type of galaxies are Spiral Galaxies. Its spiral arms are circling waves whichform new stars. This shaped galaxy consists of a flat disk with a bulge in the center and spiral arms. This flat shape disk includes stars, planets, gases and dust particles ...
Related: How galaxies form: Theories, variants and growth Around 15% to 20% of galaxies with AGNs are bright in radiowaves and are classed as being "radio loud," according to the California Institute of Technology (Caltech). Quite what makes one AGN "radio loud" and another "radio quie...
Among early-type galaxies with almost circular isophotes, E0 and E1 galaxies are, at 99.3% significance, more luminous than face-on objects classified as S0(0) and S(0)(1). This result supports the view that rotation and "diskiness" are more important in the outer regions of faint early...
The Sun has a mass of 330, 000 times the Earth. The Sun is just one star in the Milky Way galaxy that contains over 300 billion stars and scientists estimate that there are over 170 billion galaxies in the universe!However, most of the universe is what we think of as empty space. ...
You know, we used to think of galaxies as isolated systems, like islands in the sea of space.Now we know that they are always moving, usually in clusters.I mean, think about all the gravitational forces involved. We are talking about huge systems of stars and gas and dust.And since the...
aIt tell me that there are millions of galaxies and billions of planets.I can see that God is all powerful and that we are small and insignificant.And I suspect that we will have a beautiful day tomorrow.What does it tell you 它告诉我有成千上万星系和亿万行星。我能看上帝是所有强有力的...
