Recent findings lend strong support to the theory that a black hole lies at the center of the Milky Way and of many of the 100 billion other galaxies estimated to exist in the universe.
The particles could also reveal their presence in bursts of gravitational waves radiated when their clouds are torn apart around the black hole or when particles move from one axion cloud to another.
Earlier data indicated possible ice deposits in permanently Shadowed craters near the moon's poles, where water from comet impacts could have been trapped over the moon's long history.
Paradoxically, while the temperatures required for liquid water exist only in the inner solar system, the key building blocks of life, including water itself, occur primarily beyond the asteroid belt.
