Since it explored Pluto in 2015, the New Horizons spacecraft has been zooming toward NASA's most distant target yet. Join the mission team as the probe attempts to fly by Ultima Thule, an object 4 billion miles from Earth.

Martinique Island, 1974. Inspired by the writings of the Martiniquais poet and politician Aimé Césaire (1913-2008), the dreamer Robert Saint-Rose, known as Zétwall (Star in Creole), aspires to be the first Frenchman to step on the lunar surface.

A team of international scientists attempt to document the first-ever image of a black hole.

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.

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.

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.

At Arecibo Observatory in Puerto Rico, “Near Earth Asteroids: Dr. Anne Virkki” tells the story of Research Scientist Anne Virkki and her ongoing studies on asteroids and their threat to humanity. Originally from Finland, Anne Virkki shares her experience in education as well as her studies on asteroids, including her work hunting and tracking asteroids headed for Earth.

Cave paintings and lunar calendars exist in the caves and remains of prehistoric hunters studied recently. What if Prehistoric Man were clever enough to develop in depth scientific knowledge? As unlikely as it may seem, new data tend to prove that Prehistoric Man actually invented Astronomy!

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?
