NASA: Earth Observatory News 18 Nov 2019, 09:31 UTC Citizens of central Chile are accustomed to long spells of dry weather. But the past decade has brought an extreme drought that is remarkable even for a region with a semi-arid Mediterranean climate. Central Chile, where most Chileans live, has received 30 percent less rainfall than normal over the past decade, a situation that scientists are referring to as “megadrought.” With rainfall deficits of 80 to 90 percent, 2019 has been particularly dry.
Universe Today 14 Nov 2019, 20:28 UTC The 50th anniversary of Apollo 11 was a huge celebration, and Apollo 13 may be an equally big commotion. Apollo 12 is tough sell in the middle. Even the Virginia Air & Space Center, which houses the Apollo 12 capsule, uses photographs of Apollo 11 to advertise. Ouch.
Starts With a Bang! 14 Nov 2019, 17:24 UTC Pluto is definitely not the ninth planet, but a large world beyond Neptune might actually be a reality.

SciTech Daily 14 Nov 2019, 11:40 UTC Is Earth the only habitable planet in the universe or are there more worlds somewhere out there that are capable of supporting life? And if there are, what might they look like? In a bid to answer these fundamental questions, scientists are searching space for exoplanets: distant worlds that orbit other stars outside our solar system.
SciTech Daily 14 Nov 2019, 02:15 UTC Scientists have long been puzzled by the existence of so-called “buckyballs” – complex carbon molecules with a soccer-ball-like structure – throughout interstellar space. Now, a team of researchers from the University of Arizona has proposed a mechanism for their formation in a study published in the Astrophysical Journal Letters.
Centauri Dreams 13 Nov 2019, 17:19 UTC The question of habitability on planets around M-dwarfs is compelling, and has been a preoccupation of mine ever since I began working on Centauri Dreams. After all, these dim red stars make up perhaps 75 percent of the stars in the galaxy (percentages vary, but the preponderance of M-dwarfs is clear). The problems of tidal lock, keeping one side of a planet always facing its star, and the potentially extreme radiation environment around young, flaring M-dwarfs have fueled an active debate about whether life could ever emerge here.
