Popular Science: "Are We Alone: Searching for Life in Space"


Popular Science (part of Time) is offering a supermarket glossy booklet “Are We Alone? Searching for Life in Space”. 96 pages.

There are some highlights not seen before in other booklets like this.  One is an examination of the seven earth-like planets around the Trappist M-star 39 light years away, with planet E having the best chance for Earth-like temperatures, and an artist’s rendition of the surface of a moderately cold Planet F.

There is some discussion of the earth-like planet around Proxima B. an M-star and the closest to Earth at 4.2 light years.


There is a lot of attention to Europa and its subsurface ocean and likelihood of life, as well as Encedalus.  But Titan gets mentioned only in passing with the possibility of silicon-and-methane based life.  Ironically, my own Science Honor Society project in 1960  had speculated about silicon-based life, but I was hardly as accomplished as Jack Andraka (who came 53 years later, however, and that matters).  I had tried some experiments in my father’s workshop with an acetylene torch that I recall very little about now.

There is also an article about the idea of aliens eating electricity, which has been the subject of horror movies before (“Kronos”).

There is mention of the possibility of a Dyson Sphere around Tabby’s Star, as well as other theories, and a nice drawing of what it could look like.
 

There’s also an essay about keeping Mars biologically clean.
