When a white dwarf, the leftover core of a collapsed star, is in a tight orbit around another star, it can pull material from that star, leading to some pretty dramatic astronomical events.

“It seems crazy,” admitted Chyba ... In theory, as Earth spins through its magnetic field, any conductive material placed on its surface should experience a force that nudges electrons ...

As the Perseverance rover trundled about Broom Point, on the lower slopes of Witch Hazel Hill on the rim of Jezero Crater, it came across a rock that looks all bubbly and weird, like a deposition ...
