Starting tomorrow night, North and South America will see a total lunar eclipse and supermoon wrapped into one, AP's Marcia Dunn writes.

"The moon, Earth and sun will line up ... for the only total lunar eclipse this year and next. At the same time, the moon will be ever so closer to Earth and appear slightly bigger and brighter than usual — a supermoon."

Our sun will turn into a solid crystal in 10 billion years

In about 10 billion years, our sun is likely to turn into a white dwarf — a shrunken, extremely dense star whose nuclear core has burned out and gotten rid of its outer layers.

A new study published Wednesday in the journal Nature claims to reveal the first evidence that white dwarf stars form solid, crystal cores containing metallic oxygen and carbon. The oldest white dwarfs, the study finds, are likely to be almost fully comprised of crystals.
