There is no evidence that magnetic fields like this play any role in the formation of stars. But they may form paths that over long periods influence the movement of dust and gas, and therefore affect where stars form and a degree of large scale structure. At the scale of stellar systems, gravity e...

Isn't one of the much touted features of the Crew Dragon that it can (and did) dock autonomously with the ISS. No crew input required. Yes, the Crew Dragon is capable of full autonomous docking, but in this case it was apparently a joint effort. A CBS News link says this: [From https://www.cbsnews....
