I did not think that the measurements to astronomical objects lacked so much precision. Yes indeed, even the estimated distance to the great searchlight Deneb ranges from ~1400LY to 3,000 LY. So we don't know if the light left it after the end of the Roman Empire or just when they were putting the ...

With Hubble measuring the distance to the farthest objects in the universe with an accuracy of 3% I wonder if the this distance measurement to Omega Centauri could be refined. The accuracy with which we're able to measure distance depends on the distance, and the available techniques for that dista...

With Hubble measuring the distance to the farthest objects in the universe with an accuracy of 3% I wonder if the this distance measurement to Omega Centauri could be refined. Hubble may be measuring red-shift that accurately, but converting that to distance gets less precise. See: https://en.wikip...

The distance from Earth to Omega Centauri is indicated to be 18,000 light years in today's APOD. In the Omega Centauri link to May 1, 2008 the distance is estimated to be 15,000 light years. With a diameter of 150 light years the difference in distance measurement seems too large. Which is correct?...
