How weird are worlds around other stars?

Weird. Really weird.

Super-sized Jupiters orbit their stars closer than Mercury, while Earth-sized worlds have years lasting mere hours and crusts of molten magma. Other planets are on bent orbits where the seasons change the weather by a 1000 degrees, while around a neighbouring star circle split worlds with hemispheres of everlasting day and perpetual, neverending night.

There are planets that orbit twin suns like Luke Skywalker's Tatooine and other worlds that have no sun at all but are rogue drifters in the darkness of the Galaxy. Some drown under global oceans thousands of kilometers deep and others have the surfaces of giant comets or diamond mantles with tarry seas. 

These are the cousins of our own Solar System, but could any be like our own Earth?


It was epic, exciting, extreme and something-else-beginning-with-E-that-conjures-images-of-being-mauled-by-bears.

This is a popular science book (yes, I promise you will understand it) on how planets are formed and the weird and wonderful worlds we have discovered beyond our Solar System.

Published by Bloomsbury Sigma Science.

Upcoming events:

In April, I’m heading to Canada! Allegedly, there will be research BUT I’m also giving a number of public talks and signing copies of The Planet Factory, which comes out in paperback over the pond that month.

More exotically, I’m giving most of these talks with YA author, Ria Voros. Ria approached me at the start of 2018, searching for an astrophysicist to appear as a character in her new book, The Center of the Universe.

With Ria’s book coming out in April only a few weeks before the paperback version of my own, we had to go on tour. Here is a doodle video showing explaining (as best as can be) our collaboration!
