Line of Nodes & Transit of Venus
The ascending node of Venus is aligned with the Galactic Meridian or "longitude 0" of the Milky Way (which passes through the Galactic Center and is perpendicular to the Milky Way/Galactic Equator).
The line is also heliocentrically aligned with Earth around June 8 and December 9 every year right when Earth's orbital position coincides with the LHC's ATLAS and CMS detectors.
From Earth's perspective, the Sun is at the Galactic Meridian on ~June 8 and ~December 9.
It's right there at the Sun's ~June 8 position that what astronomers call the Transit of Venus takes place, which is a very rare celestial event when Venus passes right in front of the Sun due to a very precise Earth-Venus-Sun alignment (accurate in 3D):
The most recent transit pair (they come in pairs) was in 2004 and 2012 (June 8 & June 6 respectively).
