1. How many stars in our Galaxy?
The Milky Way galaxy is estimated to contain anywhere from 100 billion to 400 billion stars. However, it is difficult to determine an exact number as many stars are too faint to be detected with current technology, and the exact size and structure of the galaxy is still not fully known.
2. What Galaxy has the most stars?
The galaxy with the most number of stars currently known is the IC 1101 galaxy, which is located about 1.04 billion light-years away from Earth in the constellation Virgo. IC 1101 is a supergiant elliptical galaxy, and it is estimated to contain around 100 trillion stars, which is several times more than the number of stars in our Milky Way galaxy. However, it is important to note that our knowledge of the universe is constantly evolving, and new discoveries may reveal even more star-rich galaxies in the future.
3. How many Galaxies are there?
The exact number of galaxies in the observable universe is not known, but it is estimated to be in the range of 100 billion to 2 trillion galaxies. This wide range of estimates is due to the fact that we can only observe a small fraction of the universe, and our methods for detecting galaxies are limited by factors such as distance and the amount of light emitted by the galaxy. Additionally, the definition of what constitutes a "galaxy" can vary depending on the context and the specific criteria used for classification. Nevertheless, current observations and theoretical models suggest that there are likely many more galaxies in the universe than we can currently observe.
