Could ultraviolet radiation actually be good for the development of life?
Gravitational waves are distorted by the objects that lie in their wake – how can we learn more about their journey through the cosmos?
Can exoplanetary systems remain intact in dense stellar environments, or are their exoplanets destined to be flung into the far reaches of space? N-body simulations hint at characteristics that lead to a higher likelihood of survival.
It’s difficult to tell how the individual stars of a galaxy rotate. What can we find out just from their metal content?
High resolution images from New Horizons of the surfaces of Pluto and Charon show ancient craters, but fewer than astronomers expected.
The local gravitational tides are really good at connecting the properties of dark matter halos to the cosmic web.
