The Planet Factory: Exoplanets and the Search for a Second Earth

Twenty years ago, the search for planets outside the Solar System was a job restricted to science-fiction writers. Now it's one of the fastest-growing fields in astronomy with thousands of exoplanets discovered to date, and the number is rising fast.

These new-found worlds are more alien than anything in fiction. Planets larger than Jupiter with years lasting a week; others with two suns lighting their skies, or with no sun at all. Planets with diamond mantles supporting oceans of tar; possible Earth-sized worlds with split hemispheres of perpetual day and night; waterworlds drowning under global oceans and volcanic lava planets awash with seas of magma. The discovery of this diversity is just the beginning. There is a whole galaxy of possibilities.

The Planet Factory tells the story of these exoplanets. Each planetary system is different, but in the beginning most if not all young stars are circled by clouds of dust, specks that come together in a violent building project that can form colossal worlds hundreds of times the size of the Earth. The changing orbits of young planets risk dooming any life evolving on neighbouring worlds or, alternatively, can deliver the key ingredients needed to seed its beginnings. Planet formation is one of the greatest construction schemes in the Universe, and it occurred around nearly every star you see. Each results in an alien landscape, but is it possible that one of these could be like our own home world?

About the author

Elizabeth Tasker is an astrophysicist who spends her time building fake universes inside a computer. After a degree in theoretical physics, she went on to complete her doctorate at Oxford before moving across to the United States and Canada to build stars on any computer she was given access to. She later crossed the globe again to Japan, and is now an associate professor at the Japan Aerospace Exploration Agency (JAXA).

Elizabeth has been a keen science communicator for many years and has written for Scientific American and Astronomy Magazine, as well as articles for sites that include Nautilus, the Conversation and space.com.

There's a whole universe out there ... and this book is your journey into space.

Imagine you had a spacecraft capable of travelling through interstellar space. You climb in, blast into orbit, fly out of the solar system and keep going. Where do you end up, and what do you see along the way?

The answer is: mostly nothing. Space is astonishingly, mind-blowingly empty. As you travel through the void between galaxies your spaceship encounters nothing more exciting than the odd hydrogen molecule. But when it does come across something more exotic: wow!

First and most obviously, stars and planets. Some are familiar from our own backyard: yellow suns, rocky planets like Mars, gas and ice giants like Jupiter and Neptune. But there are many more: giant stars, red and white dwarfs, super-earths and hot Jupiters.

Elsewhere are swirling clouds of dust giving birth to stars, and infinitely dense regions of space-time called black holes. These clump together in the star clusters we call galaxies, and the clusters of galaxies we call... galaxy clusters.

And that is just the start. As we travel further we encounter ever more weird, wonderful and dangerous entities: supernovas, supermassive black holes, quasars, pulsars, neutron stars, black dwarfs, quark stars, gamma ray bursts and cosmic strings.

A Journey Through The Universe is a grand tour of the most amazing celestial objects and how they fit together to build the cosmos.

As for the end of the journey - nobody knows. But getting there will be fun.

Called "spellbinding" (Scientific American) and "thrilling...a future classic of popular science" (PW), the up close, inside story of the greatest space exploration project of our time, New Horizons’ mission to Pluto, as shared with David Grinspoon by mission leader Alan Stern and other key players.

On July 14, 2015, something amazing happened. More than 3 billion miles from Earth, a small NASA spacecraft called New Horizons screamed past Pluto at more than 32,000 miles per hour, focusing its instruments on the long mysterious icy worlds of the Pluto system, and then, just as quickly, continued on its journey out into the beyond.

Nothing like this has occurred in a generation—a raw exploration of new worlds unparalleled since NASA’s Voyager missions to Uranus and Neptune—and nothing quite like it is planned to happen ever again. The photos that New Horizons sent back to Earth graced the front pages of newspapers on all 7 continents, and NASA’s website for the mission received more than 2 billion hits in the days surrounding the flyby. At a time when so many think that our most historic achievements are in the past, the most distant planetary exploration ever attempted not only succeeded in 2015 but made history and captured the world’s imagination.

How did this happen? Chasing New Horizons is the story of the men and women behind this amazing mission: of their decades-long commitment and persistence; of the political fights within and outside of NASA; of the sheer human ingenuity it took to design, build, and fly the mission; and of the plans for New Horizons’ next encounter, 1 billion miles past Pluto in 2019. Told from the insider’s perspective of mission leader Dr. Alan Stern and others on New Horizons, and including two stunning 16-page full-color inserts of images, Chasing New Horizons is a riveting account of scientific discovery, and of how much we humans can achieve when people focused on a dream work together toward their incredible goal.
