When astronomers explore the contents and constituent parts of a galaxy somewhere in the Universe, they use various techniques and tools. One of these is to spread out the incoming light from that galaxy into a spectrum and explore its properties. This is done in much the same way as a glass prism spreads white light into its constituent wavelengths to create a rainbow.

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.

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.

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.

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

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.
