The rings are believed to have been present approximately 466 million years ago. [1] [7] [8] The Hirnantian glaciation may be a direct result of the rings shielding light from reaching the Earth, [9] and the rings may have existed for up to 40 million years.
A 2024 study suggests that Earth may have had a ring system for a period of 40 million years, starting from the middle of the Ordovician period (around 466 million years ago). This ring system may have originated from a large asteroid that passed by Earth at this time and had a significant amount of debris stripped by Earth's gravitational pull ...
Earth may have had a ring made up of a broken asteroid over 400 million years ago, a study finds. The Saturn-like feature could explain a climate shift at the time.
Mysterious ancient earth rings located on the outskirts of Melbourne were made by Australia’s Aboriginal Wurundjeri Woi-wurrung people hundreds of years ago, a new study finally reveals.. The ...
J1407b's disk has a 4-million km (2.5-million mi)-wide gap between radii 0.396 to 0.421 AU (59.2 to 63.0 million km; 36.8 to 39.1 million mi), which is believed to have been created by a nearly-Earth-sized (<0.8 M 🜨) exomoon orbiting within that gap and clearing out material, in a similar fashion to the shepherd moons of Saturn's rings.
Atlas Obscura notes that they're estimated to have been made around 200 B.C. to 600 A.D., but otherwise remain a relative mystery. Elen11/Getty The Richat Structure
the Earth's mass, its gravitational field, and its angular inertia. These are all affected by the density and dimensions of the inner layers. [20] the natural oscillation frequencies and modes of the whole Earth oscillations, when large earthquakes make the planet "ring" like a bell. These oscillations also depend strongly on the inner layers ...
Just recently on the blog I posted a series of images of Jupiter taken by JWST, some of which showed Jupiter’s faint ring. I don’t think a lot of people know that all four giant planets in our ...
