In summary, the conversation discusses new estimates for the mass of a suspected black hole and the distance between our sun and the galactic center, which is roughly 26,000 light-years away. The article also clarifies that the Milky Way is about 100,000 light years across, a size that has been reported since the early 1990s.

This Sciam article states, 'Both papers provide new, closely related estimates for the mass of the suspected black hole and the distance between our sun and the galactic center, roughly 26,000 light-years away.'

Is this number generally accepted by professionals now? If I recall, Earth is 2/3 out from the galactic center and the milky way is 200,000 ly wide. I don't know, what is the popular sentiment today?

Your memory is off by a factor of two on the size of the Milky Way: It is about 100,000 light years across.

That 26,000 light year number is more-or-less consistent with values reported since the early 1990s.
 

Related to Earth's distance from the galactic center?

1. How far is Earth from the galactic center?

The distance between Earth and the galactic center is approximately 26,000 light-years.

2. How do scientists measure the distance between Earth and the galactic center?

Scientists use a variety of methods to measure the distance between Earth and the galactic center, including parallax measurements, redshift calculations, and observations of globular clusters.

3. Has Earth's distance from the galactic center changed over time?

Yes, the distance between Earth and the galactic center has changed over time due to the rotation of the Milky Way galaxy. However, the changes are relatively small and difficult to measure.

4. Is Earth's distance from the galactic center significant in terms of the overall size of the Milky Way galaxy?

No, Earth's distance from the galactic center is relatively small compared to the overall size of the Milky Way galaxy. The Milky Way is estimated to be about 100,000 light-years in diameter.

5. What effect does Earth's distance from the galactic center have on life on our planet?

The distance between Earth and the galactic center does not have a direct effect on life on our planet. However, the location of Earth in the galaxy does affect the amount of radiation and cosmic rays that reach us, which can impact the evolution and development of life on Earth.
