Ten Thousand Years

Climate change aside, many Earth scientists think long-term climate patterns say the planet will plunge into another ice age in about ten thousand years.

That's good to keep in mind when hunting ET.  Planetary climates are likely cyclical.  Because a planet can't support life now doesn't necessarily mean it hasn't in the past or won't in the future.

Hot Times Inside Luna

A new study of Lunar Reconnaissance Orbiter images finds lava may have flowed on the Moon much more recently than previously thought-- perhaps only tens of millions of years ago instead of 3.5 billion.

That would mean the interior of the Moon remained hot and active into recent times, not the dead world we thought we knew.
