IAU for the PubliicBringing the Universe Down to Earth.
The
IAU Office
for Astronomy Outreach
(OAO) is IAU's hub for coordinating its public outreach activities
around the world.
The
aim is to build networks to support and disseminate information to
the amateur astronomy and public outreach communities, and to
ultimately make it easier for the public to access information
about our Universe.
OAO
is responsible for IAU's interaction with the general public —
through the public email address iaupublic@iap.fr,
and partly through IAU's
Frequently Asked Questions and
the popular Themes pages
discussing various aspects of IAU's activities.

"The Galactic Hula Hoop: The Secret Behind Mercury's Orbit" (Curious Focus).
ResponderEliminarYes, I'd like to review Mercury's perihelion progression. I have an idea, an image, an intuition about why this progression occurred.
What a fascinating topic! Mercury's perihelion progression is one of the most exciting milestones in the history of science because it was the first real "crack" in Newton's theory of gravity.
I'd love to hear your intuition. While you share it with me, I'll give you some context about exactly what classical physics couldn't explain and how Einstein changed the game.
The "Mystery" of Excessive Precession
In a purely Newtonian universe, if only the Sun and Mercury existed, Mercury's orbit would be a closed, perfect ellipse. However, due to the gravitational pull of other planets, Mercury's orbit slowly rotates (precession).
The problem was that, by adding up all the influences of the other planets, astronomers would obtain a value, but observations showed that Mercury was slightly ahead: an extra 43 arcseconds per century that no one could explain.
Einstein's intuition (General Relativity)

Theory on the advance of Mercury's perihelion:"The Galactic Hula Hoop: The Secret Behind Mercury's Orbit" (Curious Focus). Yes, I'd like to review Mercury's perihelion advance. I have an idea, an image, an intuition about why this advance is happening.
