Two Earth-based studies confirm water molecules are present on the Moon, but the amounts vary depending on location and time of day, Casey Honniball of NASA’s
online seminar titled “A Tale of Lunar Water,” sponsored by the
Lunar and Planetary Institute (
LPI) in Houston, Texas.

Apollo missions and by the former Soviet Union’s
Luna missions contain low levels of volatile elements though a few had high water contents, Honniball said. However, these samples represent only localized areas on the lunar surface and not the whole Moon.
The Venus Phosphine Debate Continues

Researchers remain divided on the possible discovery of phosphine on Venus, a finding that could have implications for whether life resides on this nearby planet.

Life might exist beyond Earth, at least so claimed headlines across the globe in September touting possible signs of a gas called phosphine in the atmosphere of Venus. As all of Earth’s naturally occurring phosphine is produced by microbial life, the astronomical observations of the gas, reported by Jane Greaves at the University of Cardiff, UK, and colleagues, opened the door to speculation of microscopic Venusians floating in the planet’s clouds. But a flurry of papers appeared soon after on the arXiv preprint server questioning the result. This debate received airtime earlier this month at the 2020 American Geophysical Union Fall Meeting, where Greaves presented an updated analysis of the team’s data, which co
apparently, that s a big deal because when they first spotted it, astronomers immediately began trying to explain it. although they say they didn t at first see the tails. cameras at a telescope facility in hawaii captured it in space, and what happened 13 days later really caught them by surprise. it started to change shape and spew dust. and you can see it best on that picture to the right. well, you can see it again as the arrows are coming out, that trail behind it, they say, is dust. it s estimated to be 1400 feet wide and based on computer models and other technical gizmos that they re using to monitor this thing, it s already shed possibly some 1,000 tons of this mysterious dust. they re not really quite sure what the origin of it is. for now they re doing what the rest of us would do without their impressive, fancy science degrees, they re watching it for any developments. gregg? gregg: it s not going to develop in our direction, is it, harris? reporter: no, that doesn t
