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 The idea of

This study holds the potential to help us better understand how solar flares affect planetary evolution . The TRAPPIST-1 system is an exolanetary system located approximately 39 light-years from Earth with at least seven potentially rocky exoplanets
