Wandering Stars Have Been Adrift Between Galaxies for Billions of Years
In the giant galaxy clusters in the Universe, which can consist of hundreds or thousands of galaxies, there are countless “rogue” stars wandering between them. These stars are not gravitationally bound to any individual galaxy but to the halo of galaxy clusters themselves and are only discernible by the diffuse light they emit – “Ghost Light” or “Intracluster light” (ICL). For astronomers, the explanation for how these stars became so scattered throughout their galaxy clusters has always been an unresolved question.
A Rover Could Weave its Way Between Patches of Sunlight on the Lunar South Pole
In any plan to establish a presence on the Moon, the South Pole is key. There, in the deep permanent shadows of the region’s craters, are voluminous quantities of water ice. And water ice means water, oxygen, and even rocket fuel.

What Does it Take to Make Black Holes Collide?
In a recent study published in Astronomy and Astrophysical Letters, a team of researchers at the Massachusetts Institute of Technology (MIT) used various computer models to examine 69 confirmed binary black holes to help determine their origin, and found their data results changed based on the model’s configurations. Essentially, the input consistently altered the output, and the researchers wish to better understand both how and why this occurs and what steps can be taken to have more consistent results.
