Another planet may be just right for life

WASHINGTON—Astronomers have found yet another planet that seems to have just the right “Goldilocks” combination for life: not so hot and not so cold.

Global warming shifting Earth’s wobble

WASHINGTON—Global warming is shifting the way the Earth wobbles on its polar axis, a new NASA study finds.

Melting ice sheets, especially in Greenland, are changing the distribution of weight on Earth.

And that has caused both the North Pole and the wobble, which is called polar motion, to change course, according to a study published Friday in the journal, “Science Advances.”

Astronomers say the lack of moonlight will help people see more of the oldest meteor shower known to Earth, the Perseids (pur-SEE’-uhdz).
