Galaxies

The galaxy cluster that contains the Milky Way is called the Local Group.

The first part is a flat, rotating disk.

The second part is central, stellar bulge that is made of older stars and global clusters.

The third is a halo of stars.

And the last is the black hole in the center.

Hope this helps.

The Milky Way Galaxy is a galaxy ALL the time...

That depends a lot on how you define "live". For example:

* When will it stop having a spiral shape,

* When will it have so few stars that it can no longer be considered a galaxy,

* When will the last star have died out.

Depending on the intended meaning, you get quite different answers.

The crab nebula has a diameter of about 11 light years. For comparison, the distance from the Sun to Neptune is only 0.000474385765 light years.

25,000 light years (4 times smaller than the Milky Way).

have wavelengths that are longer than normal

Because the origin was a explotion. therefore trusting evrything outward and the vacume of space cant slow it down.

There was NOT an explosion of matter into the "vacuum of space" at the start of our Universe. Rather, it was an expansion of space itself, taking matter "along for the ride." There is NO PLACE in our Universe from which matter exploding; rather, all points in space are expanding away from all other points.

Gravity is the most powerful binding force in nature. It holds together everything it can with varying forces.

No, an EO galaxy is not a type of elliptical galaxy. They are a lenticular galaxy.

All stars and constellations that we can see are in the Milky Way galaxy.

Andromeda Galaxy is the nearest spiral galaxy to our Milky Way Galaxy. It is the largest galaxy of the Local Group, which also contains the Milky Way, the Triangulum Galaxy, and about 30 other smaller galaxies.

The NGC file is a netlist that contains both logical design data and constraints This file replaces both EDIF(*1) and NCF(*2) files.

*1: EDIF = Electronic Data Interchange Format. An industry standard file format for specifying a design netlist.

*2: NCF = Netlist Constraints File. This constraints file is commonly used to define constraints for schematic editors and third-party tools

Our planet Earth belongs to Milky Way galaxy , witch is a spiral type galaxy .

There is the potential that there would be a drastic difference in what we see at night. Since the rest of the galaxy is what we are viewing when we look at the star field, having an elliptical galaxy could create a 'void' of stars in certain section of the sky where the bands of the galaxy were no longer present (compared to the current system).

An egg-shaped galaxy is called an elliptical galaxy. In the Hubble Sequence, they would be E3 or E5 Galaxies.

However, there is a galaxy called the "Fried Egg Galaxy" NGC 7742 which looks - not surprisingly, like a fried egg; however, it is a unbarred spiral galaxy.

Shadows are cast by objects that block the path of sunlight. The length of the shadow can be measured by how much of the sunlight is being blocked from hitting the ground.

In the early morning and late night, when the sun is lower on the horizon, shadows appear to be longer because the line from the sun to the object to the ground is flatter, casting a longer shadow. Around noon, when the sun is almost directly overhead, there is almost no sunlight being blocked from hitting the ground, thus casting a very small shadow.

A galaxy. Ours is the milky way, which is a barrel galaxy.

Answer- I think they are actually called star clusters. Galaxies contain much more than just stars. They contain stellar remnants, dust and gas, planets, and many other astronomical features.

There's an impossible way to classify all the shapes of 100 billion galaxies in the universe.

• A globular cluster contains hundreds of thousands of stars
• An open cluster contain less than a few hundred stars.
• A galaxy contains billions of stars.

Galaxies that emit much more radiation (different types of radiation) than a typical galaxy. This actually happens in the galaxy's center, so it's more accurate to talk about an active galactic nucleus. The active galactic nucleus is believed to be caused by a black hole. From Wikipedia: " The radiation from AGN is believed to be a result of accretion of mass by a supermassive black hole at the centre of its host galaxy."
