Two 'Dust Moons' Spotted Orbiting Earth End Decades Of Controversy In The Scientific Community
Two new studies (found here and here) have found compelling evidence for the existence of 'dust moons' called Kordylewski dust clouds. There's a lot of strange things following the Earth around, from captured mini-moons to a growing shell of space junk, but this particular phenomenon has eluded scientists for decades.
To understand the Kordylewski dust clouds (or KDCs for short) you have to know something about gravity – specifically, Lagrange points. You may have heard of them when reading about NASA's plans for a Lunar Orbital Gateway-Platform, but here's the simple version: when you have two massive objects in space – like the Earth and the Moon – both of them exert a gravitational force on the smaller objects around them.
However, there are certain points in space that are equal distances from the Earth and Moon where the gravitational pulls are also equal. Anything that hangs around these areas will have a stable orbit, at least in the case of the L4 and L5 Lagrange points. The Earth-Moon L4 and L5 points form two equilateral triangles with apexes midway between the Earth and Moon, and that's where the Kordylewski dust clouds were predicted to be.

如果那是月球...那又是什麼呢...不!不是我們的太陽
If that's the moon...what is that...No not our Sun
