How supermassive black holes (SMBHs) in the centers of galaxies accrete material, how they feed back into the surrounding region, and how they regulate these processes to influence the evolution of their galaxies are all hot topics in astronomical and astrophysical research. Astronomers are nearly certain that all large galaxies like the Milky Way have […]

Moon missions come in all shapes and sizes, from car-sized rovers packed with scientific equipment to towering rocket payloads—and now, a small, shape-shifting machine that is about the size of the average palm.

Binary asteroid systems are widespread throughout our inner solar system. For decades, the standard paradigm held that many of them form when a rapidly spinning primary asteroid casts off material, which then reaccumulates into an elongated moon orbiting near the Roche limit.
