150,000,000,000.
Population I (High metal content) stars are generally found in the arms of spiral galaxies, whereas population II (Medium metal content) are generally found towards the centre of the galaxies.
The Milky Way galaxy has spiral arms where a lot of new stars are being born, including the Orion Arm where our solar system is located. These spiral arms are regions of higher density that promote the formation of new stars due to gravitational interactions between gas and dust.
This type of galaxy is categorized as a spiral galaxy. The bulge at the center contains older stars, while the spiral arms consist of younger stars and gas and dust regions where new star formation occurs. The Milky Way is an example of a galaxy with a bulge and spiral arms.
About two thirds of all spiral galaxies are barred. The Milky Way is classified as a barred spiral galaxy.
New stars are typically found in the spiral arms of a spiral galaxy. This is because the density of gas and dust is higher in the arms, creating the conditions necessary for star formation to occur. The gravitational forces within the spiral arms also play a role in triggering the collapse of gas clouds into new stars.
milky way is a spiral galaxy spiral galaxies have younger stars in the arm and older stars in the middle
A galaxy is a huge group of stars that form a spreading spiral. Our own Milky Way galaxy is an example of a spiral galaxy.
Gallifrey is in the constellation of Kasterborous, which is in (as the TimeLords know it) Mutters Spiral, or as the humans know of it - the Milky Way.
The average age of stars in a barred spiral galaxy varies, but it typically ranges from a few million years for young, massive stars to several billion years for older stars. Many barred spiral galaxies contain a mix of stellar populations, with younger stars concentrated in the spiral arms and older stars found in the central bar and bulge. Overall, the average age can be around 3 to 10 billion years, depending on the specific galaxy and its star formation history.
Many stars together can make up a galaxy. Depending on the arrangement of the stars, they could either make up an elliptical, spiral, barred spiral, lenticular, or irregular galaxy. Stars can also be together by gravity in clusters. Stars that are clustered together in a spherical group are called globular clusters. Many stars are binary stars, meaning that 2 stars circle around either each other, or around a central point of gravity. These are the most basic star groupings in which there are "many" stars.
Yes. Some spiral galaxies do contain at least 1 trillion stars.
A spiral galaxy nucleus contains a mass of stars in a "bulge" and is thought that many contain supermassive black holes at the very core of the nucleus.-In galaxies with tightly wound spiral arms the bulge generally contains old, red stars with low metal content (called population II stars); whereas galaxies with more loose arms generally have younger, blue stars (called population I stars). Some bulges have similarities to the elliptical galaxies and others are similar to disk galaxies.-Evidence of supermassive black holes have been discovered in many galaxies and theorized to exist in many more galaxies (at least the larger ones). Our own Milky Way Galaxy contains a supermassive black hole at its core.
Some of them - particularly the ones in our spiral arm.
A spiral galaxy is just a type of galaxy but I can tell you that the stars in the middle are the oldest and the ones on the outside are the youngest.
Spiral galaxies are named for the (usually two armed) spiral structures that extend from the centre into the disk.The spiral arms are sites of ongoing star formation and are brighter than the surrounding disk because of the young, hot stars.See related link for a pictorial representation.
It has all types of stars with different ages
Population I (High metal content) stars are generally found in the arms of spiral galaxies, whereas population II (Medium metal content) are generally found towards the centre of the galaxies.
