Although dark matter is a central part of the standard cosmological model, it’s not without its issues. There continue to be nagging mysteries about the stuff, not the least of which is the fact that scientists have found no direct particle evidence of it. Despite numerous searches, we have yet to detect dark matter particles. So some astronomers favor an alternative, such as Modified Newtonian Dynamics (MoND) or modified gravity model. And a new study of galactic rotation seems to support them.

Navigation Could be Done on the Moon Just by Looking at Nearby Landmarks
When humans start living and working on the Moon in the Artemis missions, they’re going to need good navigational aids. Sure, they’ll have a GPS equivalent to help them find their way around. And, there’ll be LunaNet, the Moon’s equivalent to the Internet. But, there are places on the lunar that are pretty remote. In those cases, explorers could require more than one method for communication and navigation. That prompted NASA Goddard research engineer Alvin Yew to create an AI-driven local map service. It uses local landmarks for navigation.
