The Farthest

The Farthest – Voyager in Space

THE FARTHEST tells the captivating tales of the people and events behind one of humanity’s greatest achievements in exploration: NASA’s Voyager mission, which celebrates its 40th anniversary this August. The twin spacecraft—each with less computing power than a cell phone—used slingshot trajectories to visit Jupiter, Saturn, Uranus and Neptune. They sent back unprecedented images and data that revolutionized our understanding of the spectacular outer planets and their many peculiar moons.

Still going strong four decades after launch, each spacecraft carries an iconic golden record with greetings, music and images from Earth—a gift for any aliens that might one day find it. Voyager 1, which left our solar system and ushered humanity into the interstellar age in 2012, is the farthest-flung object humans have ever created. A billion years from now, when our sun has flamed out and burned Earth to a cinder, the Voyagers and their golden records will still be sailing on—perhaps the only remaining evidence that humanity ever existed.

The Planet Factory


Exoplanets and the Search for a Second Earth

by Elizabeth Tasker

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?
