A seismic shift occurred in astronomy during the Scientific Revolution, beginning with 16th-century polymath Copernicus and his proposal that the Earth revolved around the sun. By the 17th century, ...

A new study indicates the collision of Theia and the Earth about 4.5 billions years ago might have created more than one moon ...

Scott Manley is indicating that what I have been observing in the Barry-1 satellite orbital variance is not enough proof for the IVO quantum drive.

Figure 1: The semi-major axis versus eccentricity distribution for various ‘cold’ populations. In all cases only objects with inclinations less than 4° are plotted. a, Real Kuiper-belt objects.

“While we find that there are no stable polar orbits around the Earth-Moon orbit with the current day semi-major axis, polar orbits were stable immediately after the formation of the Moon, at ...

While the eccentricity cycle has been a major factor thought to drive glacial/interglacial cycles, newer research has suggested that they instead may result from a series of obliquity or ...
