Talk:Galactic anticenter

Possible image
I found an image of the galactic anticenter provided by NASA: http://fermi.gsfc.nasa.gov/science/resources/sims/EGRET.gif

Explanation needed
Can someone please explain how there can be an opposite to the galactic center? —Preceding unsigned comment added by Tjmpb (talk • contribs) 17:37, 8 August 2008 (UTC) As I understand, it is a subjective term. Different for all places and times of the earth. Look at the galactic center, then the anti-center is behind your back in the opposite direction. 217.208.211.240 (talk) 09:50, 24 December 2008 (UTC)

It's not meant to designate an actual object or a location in three-dimensional space. It is really meant to indicate the direction away from the Galactic center. If you face the Galactic center and then turn exactly 180 degrees around, you are "facing the Galactic anticenter." That's all. 98.210.207.23 (talk) 02:44, 2 September 2010 (UTC)An astronomer

Diagram Point
As of December 2015 more than half the content of this article was about what the galactic anticenter is not. That's helpful and notable. But the article could be improved with an image showing the point location today, instead of just "Alnath is the closest bright star". Even better, the point's history and future (as the solar system revolves around the galactic center) could be charted. Bob Stein - VisiBone (talk) 15:18, 3 December 2015 (UTC)

State Coordinates
The Galactic Center in the equatorial coordinate system is:

RA 17h45m40.04s, Dec −29° 00' 28.1"

I believe that by adding 180 to the right ascension, and flipping the sign on the declination, this computes the coordinates of the anticenter:

RA 197h45m40.04s, Dec 29° 00' 28.1"

Whatever they are, the coordinates should be part of this article. Bob Stein - VisiBone (talk) 15:18, 3 December 2015 (UTC)

Location in Taurus
Elnath, referred to alternatively as El Nath or Alnath, has been considered Beta Tauri, not Gamma Aurigae, by the International Astronomical Union, since 1930. Regardless, indeed the GA is generally accepted to fall within Auriga. — Preceding unsigned comment added by 128.220.159.68 (talk) 20:34, 28 December 2016 (UTC)

Revised definition
I revised and shortened the definition somewhat, following suggestions previously given by others on this page. Previously the entry for the GA defined it as a "theoretical point", but it's better defined as a direction in space (defined relative to the observer's location on Earth and opposite the direction toward the Galactic center) rather than a point, because it's not a point in 3-dimensional space, and the word "theoretical" isn't needed. This direction corresponds to a point on the celestial sphere. I removed two references to journal articles describing research about the Galactic center, since those articles didn't specifically say anything about the Galactic anticenter. I also capitalized Galactic following astronomical convention to use a capital G when referring to the Milky Way Galaxy. Aldebarium (talk) 00:55, 30 December 2016 (UTC)

Picture
the picture which has caption "Overview sketch of the Milky Way with the direction of the Galactic anticentre indicated as seen from the Solar System" is some picture of the Pinwheel Galaxy. (ok please don't blame me if I'm wrong) User:Hamterous1 (discuss anything!🐹✈️) 18:04, 12 April 2024 (UTC)
