no.
All of them are. Generally elliptical galaxies are the oldest.
The Milky Way Galaxy and about 17 other galaxies within 3 million light-years are collectively known as the Local Group. This group includes galaxies such as Andromeda (M31), Triangulum (M33), and the Milky Way.
All galaxies have black holes, even the Milky Way.
Venus is in our solar system and so it is in the same galaxy as we are. We are in the Milky Way galaxy, as are all the stars that you can see.
All of them. The Solar System is part of the Milky Way Galaxy, one of several billion galaxies in the Universe.
Probably, but impossible to tell as we are only just seeing planets within our own galaxy.
Over time - billions of years - galaxies will merge with other galaxies. In about 3 billion years, the Andromeda galaxy will merge with our own galaxy, the Milky Way.However, the separation between galaxies is so great, that not all galaxies will merge unless the fundamental issue of the amount of mass in the Universe is determined.If we live in a "contracting universe" then eventually all galaxies will merge.
They all contain some form of sphere (ball)
Not all galaxies have black holes. While many galaxies, including our own Milky Way, have supermassive black holes at their centers, there are also galaxies that do not have black holes. The presence of a black hole in a galaxy depends on various factors such as the size and age of the galaxy.
Here are some galaxies (all of them part of the Local Group): The Milky Way, our own galaxy The Andromeda Galaxy, another large galaxy The Triangulum Galaxy, another large galaxy The Large Magellanic Cloud, a dwarf galaxy close to the Milky Way The Small Magellanic Cloud, another dwarf galaxy close to the Milky Way
local group A+
Actually, most galaxies are all moving away from all other galaxies, not just from ours. The exception is the Andromeda galaxy, with which the Milky Way is on a collision course.
