Unusal Moon Magnetism may be due to gravity from Earth

A new model for generating a global magnetic field in the ancient moon could help solve a 40-year-old mystery. The Earth has a magnetic field because it has a spinning solid core surrounded by hot metallic liquid, which churns around lava-lamp style and generates magnetism. But the moon is too small and cool to possess such a molten interior and therefore lacks a global magnetic field.

Russia Returning to Mars After 15-Year Break

Giant Radio Telescope Sees Inside Galactic Smash-Up

A radio telescope array being built in the highest, driest desert in the world has photographed two colliding galaxies for its first public-test shots. The new images reveal a flurry of star formation within thick clouds of gas and dust at the Antennae Galaxies’ impact zone, 45 million light-years away.
