There are approximately 25,000 "city killer" asteroids in near-Earth orbit—and most are yet to be found. Small enough to evade detection, they are capable of large-scale destruction, and represent our greatest cosmic threat. But in September 2022, against all odds, NASA's Double Asteroid Redirection Test (DART) mission deliberately crashed a spacecraft into a carefully selected city killer, altering the asteroid's orbit. In How to Kill an Asteroid, award-winning science journalist Robin George Andrews reveals the development of the technology that made it possible

Sixty-six million years ago an asteroid as large as Mt. Everest hit what is now the Yucatan Peninsula at a speed ten times faster than the fastest rifle bullet. Debris from the impact blew into space, re-entered the atmosphere as a swarm of shooting stars that burned the global forests and grasslands, leaving behind a thin global layer containing rock from the asteroid and from Mexico, and smoke from the fires. This layer marks one of the greatest extinctions in Earth history including not just dinosaurs, but also fish, plankton, ammonites, and plants making up about 75% of the known species.

1 in 8 UK males will be diagnosed with prostate cancer, more than 130 new cases are discovered each day and, on average, one man dies from the disease every 45 minutes. Despite these statistics, and the fact that there are getting on for half a million men living with, or in remission from, prostate cancer in the UK, the condition is rarely discussed publicly and most men ignore the warning signs.

The solar system most of us grew up with included nine planets, with Mercury closest to the sun and Pluto at the outer edge. Then, in 2005, astronomer Mike Brown made the discovery of a lifetime: a tenth planet, Eris, slightly bigger than Pluto. But instead of its resulting in one more planet...
