Hurricane María abated, the news crews packed up and left Puerto Rico, and the interest of the international community turned elsewhere. What happened next?

At the edge of our solar system supposedly lies an immense planet. Five to ten times the size of the Earth. Several international teams of scientists have been competing in a frantic race to detect it, in uncharted territories, far beyond Neptune. The recent discovery of several dwarf planets, with intriguing trajectories, have put astronomers on the trail of this mysterious planet. Why is this enigmatic planet so difficult to detect? What would a ninth planet teach us about our corner of the universe? Could it help us unlock some of the mysteries of our solar system?

In Chile's Atacama Desert, astronomers peer deep into the cosmos in search for answers concerning the origins of life. Nearby, a group of women sift through the sand searching for body parts of loved ones, dumped unceremoniously by Pinochet's regime.

Billions of years ago, Venus may have harbored life-giving habitats similar to those on the early Earth. Today, Earth's twin is a planet knocked upside down and turned inside out. Its burned-out surface is a global fossil of volcanic destruction, shrouded in a dense, toxic atmosphere. Scientists are now unveiling daring new strategies to search for clues from a time when the planet was alive.

Part of the Almost Famous series. Jocelyn Bell was a graduate student at Cambridge in 1967 when she pushed through the skepticism from her superiors to make one of the greatest astrophysical discoveries of the twentieth century. While Jocelyn was belittled and sexually harassed by the media, the Nobel Prize was awarded to her professor and his boss.

Photo sequence of the rare transit of Venus over the face of the Sun, one of the first chronophotographic sequences. In 1873, P.J.C. Janssen, or Pierre Jules César Janssen, invented the Photographic Revolver, which captured a series of images in a row. The device, automatic, produced images in a row without human intervention, being used to serve as photographic evidence of the passage of Venus before the Sun, in 1874.

The first feature from Alison McAlpine is a dialogue with the heavens—in this case, the heavens above the Andes and the Atacama Desert in northern Chile, where she alights on the desert- and mountain-dwelling astronomers, fishermen, miners, and cowboys who live their lives with reverence and awe for the skies.

Chaco Canyon, located in northwest New Mexico, is perhaps the only site in the world constructed in an elaborate pattern that mirrors the yearly cycle of the sun and the 19-year cycle of the moon. How did an ancient civilization, with no known written language, arrange its buildings into a virtual celestial calendar, spanning an area roughly the size of Ireland?
