Most of the material universe is organized into galaxies of stars together with gas and dust. There are three main types of galaxy: spiral, elliptical, and irregular. The Milky Way is a spiral galaxy, a flattish disc of stars with two spiral arms emerging from its central nucleus. About ...
There are three main types of galaxy: spiral, elliptical, and irregular. The Milky Way[Line(5)] is a spiral galaxy: a flattish disc of stars with two spiral arms emerging from its central nucleus. About one-quarter of all galaxies have this shape. Spiral galaxies are well supplied with ...

Galaxies are giant structures made of dust, gas, stars and other celestial bodies spread through an immense area of space. Our own galaxy, the Milky Way, consists of more than a hundred billion stars strung across tens of thousands of light years. Galaxi
Galaxies(星系) are made up of three main things: stars,clouds of gas and dark matter. Dark matter can not be seen and scientists only know that it 1.(存在) because of the influence its2.(重力) has on matter that can be seen. On earth,3.(physics) use particle acceleratora (粒子力...

We present the discovery of three faint dwarf galaxies and a globular cluster in the halo of the Andromeda galaxy (M31), found in our MegaCam survey that spans the southern quadrant of M31, from a projected distance of ∼50 to ∼150 kpc. Though the survey covers 57 deg2, the four ...

On the surface of the Earth, the lithosphere is composed of three main types of rocks: • Igneous - rocks formed by solidification of molten magma. • Sedimentary - rocks formed by the alteration and compression of old rock debris or organic sediments. • Metamorphic - rocks formed by ...
