Now tens of billions of kilometers from Earth, the two Voyager spacecraft are streaking out into the void. What will we learn about the Galaxy, the Universe, and ourselves from Voyager's epic Journey to the stars?
Join a small team of rocket designers as they open a window into the future of space travel.
It was one of the greatest mysteries in modern science: a series of brief but extremely bright flashes of ultra-high energy light coming from somewhere out in space. What can we learn from the violent birth of a black hole?
Over the next decade, the United States, Japan, India, China, Russia, and even private companies, are planning to send spacecraft to explore the moon. These missions are looking for resources that may one day allow humans to settle permanently in space.
Cosmology has been turned on its head by a stunning discovery that the universe is flying apart in all directions at an ever-increasing rate. The scientists who made this discovery were awarded the Nobel Prize in Physics.
Explores one of the deepest mysteries about how our universe came to be. Scientists are mounting new efforts to figure out how matter survived, and what happened to its birth twin, a mysterious substance known as antimatter?
The hunt for planets beyond our solar system has reached a fever pitch. Scientists are beginning to envision what these worlds are like, and in the process, redefining what a planet might need to spawn life.
Many astronomers now conclude that what we can see, the stars and galaxies that stretch out to the limits of our vision, represent only a small fraction of all there is. Does the universe go on forever? Where do we fit within it?
How does energy stitch the cosmos together, and how do we fit within it? This episode climbs the power scales of the universe, from atoms in the cold reaches of space to distant realms so strange and violent they challenge our imaginations.
From the fires of our Sun's birth, twin planets emerged: Venus and Earth. Nature draped one world in the greens and blues of life, while enveloping the other in acid clouds... high heat... and volcanic flows. Why did Venus take such a disastrous turn?
Pandora is the idyllic blue world featured in the movie Avatar. It's location is a real place: Alpha Centauri, the nearest star to our Sun and the most likely destination for humanity's first interstellar voyage.
The search for Earth-like planets is reaching a fever-pitch. Does the evidence so far help shed light on the ancient question: Is the galaxy filled with life, or is Earth just a beautiful, lonely aberration?
Astronomers tracking stars at the center of the galaxy have found the best proof to date that black holes exist. Now, they are shooting for the first direct image of a black hole.
It's the ultimate buddy movie. Pete Conrad and Alan Bean were the second pair of Apollo astronauts to land on the moon. They combined precision with a sense of humor. But it was the rocks they picked up that would define the mission's legacy.
How long will the Universe as we know it survive? The answer depends on whether Stephen Hawking was right about the decay of black holes. Modern theories suggest that our universe may be a blip within a much grander sweep of time.
The universe has long captivated us with its immense scales of distance and time. How far does it stretch? Where does it end? The mind-blowing answers come from a theory describing the first micro-moments of our universe.
Meet the new record-holder for the largest black hole known in the universe. It weighs in at an estimated 21 billion solar masses. Find out what impact giants like these have had on the universe, galaxies, and even planets like ours.
Why some tropical storms erupt into monster hurricanes capable of wrecking coastlines. Can they be predicted? A SpaceRipTV original with Space.com.
Did Mars long ago develop far enough for life to arise? If so, does anything still live somewhere underground? The search for answers has revealed the forces that long ago doomed the Red Planet.
From the Cassini spacecraft comes one of the greatest photographic collections. Scientists are using it to uncover a trail of clues pointing to the energy sources and complex chemistry needed to spawn life.
How massive solar eruptions can take aim at our high-tech society. Explores past events such as the solar storms of Halloween 2003 and 1859, and dives into the Sun to find out what causes our star to turn angry.
Scientists have been reconstructing the history of the Moon by scouring its surface, mapping its mountains and craters, and probing its interior. Find out what they are learning about our own planet's beginnings.
It was the first extra solar planet recorded in visible light. It was spotted by the Hubble Space Telescope on the periphery of a bright star known as Fomalhaut. Now, astronomers believe it's really two planets by their action on a giant ring of dust.
We've all seen pictures of Earth from space, but rarely against the starscapes of the Milky Way galaxy. Here is Earth in its cosmic context, including stars, interstellar gases, the moon, the sun, aurorae, and solar winds.
Revel in Earth as Art. Landsat missions were launched for scientific purposes, but they make up one of the most awe-inspiring collections of beautiful images of our home planet.
