What Is Spherical Astronomy?

Spheroids are generally formed by Gram-negative bacteria because their cell wall components are complex and difficult to remove; Gram-positive bacteria's cell wall is mainly composed of peptidoglycans, and spheroids can also be formed if the enzymatic hydrolysis time is short; yeast Spheroids can also be prepared after treatment with zymolyase from Arthrobacter luteus.

Spheroid

Right!

Spheroids are generally composed of

There are two methods for preparing Gram-negative bacterial spheroids: (1)

Spheroids are also called " Barnard celestial bodies ." The spheroid is very dark and can only be observed with a large telescope. Some people think that it is some protostars that are in the stage of gravitational contraction; but others think that the spheroid's proportion of dust and gas is too large to meet the requirements of star raw materials, and the density is too small, only 10 to 1,000 molecules per cubic centimeter, Not enough to cause gravitational contraction. At present, more than 200 large spheroids have been observed within a 500-second gap near the sun. Their angular diameter is about 3 'to 20', the line diameter is about 10 to 10 astronomical units, the mass is about 0.1 to 750 solar masses, and the temperature is about 7 ~ 15K. It is estimated that there should be 25,000 large spheroids in the Milky Way, the main components are H2, CO and some organic molecules. A spheroid is a small, dense, spherical dark nebula. It is a transitional body from a nebula to a star. This is a spherical dark nebula found on the background of many bright and diffuse nebulae since 1946. Mass is sometimes only a few percent to a few thousandths of the sun. They are many on the background of Sagittarius M8, completely opaque, and some people think that the spheroid is the original star that is shrinking. Large nebulae in the universe will be broken down into small gas clouds due to various reasons. Their mass is equivalent to the mass of stars. Such small gas clouds are called protostars. During the shrinking process of the protostar, the center density is getting higher and higher, and the temperature is getting higher and higher, until the nuclear reaction takes place inside, which causes the radiation to glow in the visible light region and become a star. Some people think that the density of spheroids is too small, and the proportion of solid and gas particles is too large to become stars. More than 200 large spheroids have been observed in the Milky Way.
