Map of known water ice deposits near the moon's south pole, via NASA’s Lunar Reconnaissance Orbiter (LRO). This ice has the potential to reveal some of the moon's history, and it might also be of use to future moon explorers.
We tend to think of the moon as a dusty, bone-dry place, and, for the most part, that's true. But the moon does have ice, in particular at its south pole, hidden in shadowed craters. How did the ice get there? A new study suggests it might have various sources, both ancient and more recent. Read more.
For a brief time in 1976, it seemed as if NASA's Viking landers had found microbes on Mars. Those results have been vigorously disputed in the years since, but the original experiment's principal investigator, Gilbert Levin, still maintains they really did detect Martian microbes. Read more.
In its annual winter outlook for temperature, precipitation and drought, NOAA says winter temperatures in 2019-2020 are likely to be above average in most of the western, southern and eastern U.S., as well as in Alaska and Hawaii.

View at EarthSky Community Photos. | Does this cloud look like a seahorse to you? Dr Ski captured this image at sunrise on Tuesday morning in Valencia, Philippines. Seeing a seahorse in a cloud, or a face in the moon, are examples of what’s called pareidolia. Look for examples here.
Watch for this eerie light - called the zodiacal light - about 2 hours before sunrise in the Northern Hemisphere. From the Southern Hemisphere, watch for it after sunset. Read more. Photo: Yuri Beletsky in Chile caught the zodiacal light in the evening around this time last year. In this image, the Milky Way stretches across the sky, while zodiacal light can be seen as the faint pyramid-shaped light toward the bottom of the image. The 2 bright planets within the zodiacal light in this image are Venus (closest to horizon) and Jupiter.
