- They are the one-stop-shopping places for learning all about the nature and variety of stars in the Universe. They're unique, because in clusters, all the stars were born at about the same time.
- They sort of sound like the same phenomenon, but Pulsars and Quasars are very different. Pulsars are tiny--only a few miles across--but they spin as fast as a kitchen blender.
- Is science-fiction rooted in science? Has science caught up to science-fiction, past and present? Is there any scientific technology that has surpassed science-fiction? This episode explores these questions and more.
- The seven wonder of our solar system are discussed: Enceladus' geysers, Rings of Saturn, Jupiter's Great Red Spot, the Asteroid Belt, Mars' Olympus Mons, the Surface of the Sun, and planet Earth.
- Scientists have taken a serious look at the possibility of time travel. Current scientific theories offer some likely prospects but engineering a working time machine, even if possible, remains a distant prospect.
- This program repeatedly hammers home the catastrophic impact of a large asteroid impact on earth. Several known large impacts of the past are recounted as well as some recent near hits. Recent and planned missions to explore objects in the asteroid belt are reviewed.
- From highly sophisticated and sensitive space telescopes that look from afar to space probes that rendezvous with celestial objects to return samples, this program looks a few of the more dramatic space explorations missions in recent years.
- We earthlings have what may be a unique opportunity in all the universe to view a stellar corona during a total solar eclipse. And while a solar eclipse is rare even on Earth, other eclipses are incredibly common despite the near perfect alignment required. In addition to the solar and lunar eclipses we are all familiar with this program looks at interplanetary and interstellar eclipses
- It's the apocalyptic finale of our galactic neighborhood, We've now uncovered sizzling clues about our home star's violent demise. And the outcome doesn't look good for planet Earth. New cutting edge science traces the real horrors awaiting our planet as our Sun unleashes it's final fury!
- 2007–201545mTV-147.0 (66)TV EpisodeThe planets of our solar system have experienced epic catastrophes throughout their long history, both raining down from outside and bubbling up from within. We'll voyage back in time to investigate the violent events that profoundly shaped the planets, including earth itself. We'll witness stunning revelations about what transformed Mars into a barren, hostile desert...The disaster that changed Venus from temperate to hellish...The impact that blew away Mercury's mantle, turning it into a planetary core...A colossal disturbance that rearranged the orbits of the gas giants...Titanic impacts on Jupiter...And how a lost moon may finally explain Saturn's rings.
- Earth may seem like the most hospitable planet in the solar system. But look again. Startling new discoveries reveal the blue planet has been plagued by more chaos and destruction than scientists once imagined. Stand on the Earth billions of years ago as a primitive planet slams into it. Shiver as our entire globe is frozen over like a gigantic snowball. Feel the heat as mammoth volcanoes scorch the landscape and darken the sky. From a cosmic gamma ray burst frying away the ozone layer to an Everest-size asteroid slamming into the ocean, we'll reveal new information about how these unparalleled events drove life to the brink of total extinction. Out of this continuous devastation, how has our planet--and life--got to where it is today? Are the worst days behind us--or lurking in the distant future?
- Factual information about Mars woven into a fictional story about a crash landing there.
- The enterprising alien who wants to visit Earth faces a number of daunting challenges. This program examines the advanced technologies he would need with an emphasis on concepts for interstellar travel humans are exploring.
- "The Universe" explores where the universe came from and whether a creator had a hand in making it. As scientists learn more about the universe our ideas about exactly what God made (the earth, the universe, the multi-verse even nothing but empty space) have come into question. But we always seems to be left with something new that a creator had to make to get things going.
- The key to understanding the universe seems to be understanding its smallest components. But reconciling the two has proved to be a tremendous scientific challenges as the behavior in the quantum realm bears little resemblance to the universe we know. This program explains some of the strange behavior scientists have discovered at the smallest scales.
- Now that the Voyagers have visited the outer planets of the solar system they are heading for new adventures in places astronomers call the Oort Cloud, the heliopause, heliosheath and eventually they may encounter double stars and exoplanets, some of which may pay a visit to the solar system one day or explode showering us with radiation. If the Voyagers live so long they will experience the local fluff, local bubble and other parts of the habitable zone of the galaxy.
- Checking into the mysteries relating to the destruction of both Sodom and Gomorrah. Were they astronomical events?
