What are the names of galaxies that students know? Let’s briefly introduce the galaxies in question.

Introduction to the Four Major Galaxies 1: Elliptical Galaxy

The movement of stars is mainly irregular. It is different from the rotational movement of spiral galaxies. There is only a little irregular movement. There is only a little interstellar matter. There are very few young stars. There are not many open star clusters. There are many stars. It is an old star belonging to Population II. Larger elliptical galaxies have globular star clusters dominated by old stars.

Introduction to the Four Major Galaxies 2: Whirlpool Galaxy

There is a structure with a spherical core in the center, surrounded by surrounding galaxies. 1. Has a considerable total angular momentum. 3. The bulge core is similar to an elliptical galaxy, with many old stars belonging to Population II, and usually a supermassive black hole hidden in the center. 4. The galactic disk is flat, accompanied by interstellar matter, young Population I stars, and Open star clusters, rotating together around the spherical core.

Introduction to the Four Major Galaxies 3: Barred Spiral Galaxies

The motion characteristics of barred spiral galaxies are: the core is often a massive, rapidly rotating body, the motion state and spatial structure are complex, and the gas and stars inside and near the bar structure have non-circular motion; the galaxy disk appears to be outside the galaxy. occupies a dominant position and constitutes a large part of the mass of an astrological system.

The Frontier of the Universe PPT, Part Six: Brief Analysis of Writing Method

(1) Make good use of metaphors

Comparing the entire universe to the sea, and comparing the surface of the earth to the "cosmic ocean shore" is vivid and can better reflect the boundlessness of the universe. Compare our exploration of the universe to "wading into" the ocean. Comparing people on earth to dust and so on.

(2) Clever use of personification

"The sea water is charming, the sea is calling to us." The word "call" is used to vividly express our yearning for the universe. The sea is like a mother calling her children to understand her more deeply.

(3) Pen with passion

The language of the article is full of emotion and literary. For example, "Just thinking about the universe... is as dizzying and shuddering as recalling a cliff slip a long time ago." Use "dizzy and trembling" to describe people's excitement when facing the many mysteries of the universe.

(4) The language contains philosophy

The author uses some classic language and is philosophical. For example, "Curiosity is human nature, understanding is a pleasure, and knowledge is a prerequisite for survival." Beautiful and vivid language explains profound and abstract scientific knowledge in an easy-to-understand, concrete and interesting way.

The Frontier of the Universe PPT, Part Seven: Summary

Our earth is just the shore of the vast sea in the universe. As for the universe outside the earth, whether there is a so-called "cosmic boundary" requires our unremitting efforts to explore and discover.
