I
am a layman when it comes to astronomy. I have a high school
education (largely retained), and decades of random reading about the
heavens (perhaps less retained). But I am also a star gazer. It’s
nice every now and then to go out at night, stare at the sky, and let
the mind wander where it will. It’s precisely moments like that we
forget about the minutiae of daily life and remember that Earth
hurtles 30 km/sec through a void, not to mention that the myriad of
life around us, billions of species, is not forever—that the
greenhouse effect, regardless accelerated by humankind or not, will
eventually burn everything to the ground, leaving only rock.
Bringing to one place all the pertinent information on our solar
system known as of 2019 is the BBC’s The Planets by Brian
Cox and Andrew Cohen (2019). It is star gazing of the most informed
variety.

embarking on a similar planets project twenty years ago, the 2019
edition of The Planets integrates what was known then with the
information that has come to life or gelled in the meantime, all to
create the most detailed picture of our solar system to date. Why is
Mercury’s orbit the most irregular? How did Venus’ ecosystem
come to be so hellish? Is/was their life on Mars? What hope do
Jupiter’s moons offer for human life occurring beyond Earth? What
exactly are Saturn’s rings, and how did they come to be formed?
These and many, many other fascinating topics and facts are related,
in lucid, wonderfully structured fashion. If there is anyone on
Earth who knows how to collect, organize, and present information in
an interesting, engaging fashion, it is BBC. The material in the
book is enough for a semester’s course providing the tightest
summary of the solar system.
