This Blog Site was established as an Internet Monument to one of the greatest Astronomers and popularizers of science of the twentieth century - Dr. Carl Sagan. Cosmos was the landmark documentary for which he will be long remembered. This Internet Project is dedicated to his life, work and memory. Herein we will discuss many of the issues that occupied Sagan throughout his life (Astronomy, SETI, the future of humanity, space exploration, science and education).
Birds do it, bees do it and people do it to. But, how on Earth did dinosaurs do it? Find out today on Cosmic Visions as we explore - Everything you ever wanted to know about dino sex, but where afraid to ask.

Today on Cosmic Visions we are going to take a foray into the field of Archaeoastronomy and explore how our ancient forbearers decoded the night sky and built the foundations of civilization. Not with the help of ancient astronauts but through their own perseverance and innate intellect.
Our ancestors' relationship with the heavens led to some of humankind's ancient discoveries and greatest creations. The ancient Greeks discovered Earth was round; the Polynesians used the sun and stars to navigate vast oceans in simple canoes; some think amazing structures like Stonehenge were designed to observe the sky. Now, Known Universe examines mankind's first observations of the cosmos to understand how they put us on the path to modern discovery.
Today on Cosmic Visions we present an episode of the National Geographic Channel’s outstanding documentary series “The Known Universe” that deals with two endeavours very dear to our hearts, the exploration and eventual settlement of the new frontiers of sea and space. These are the main goals of the organization we are closely associated with – The League of New Worlds.
The League of the New Worlds, founded in September of 1989, intends to establish a permanent human presence in the oceans. In so doing, we will engineer the habitats, procedures and processes for the space frontier. This formal engineering process is called: Space-Ocean Analogs.
Our all volunteer staff of engineers, ocean and space scientists, scientists, aquanauts, students and others all seek the same goal - to build the new outposts, colonies and cities of the New Worlds.
If you are interested in discovering more about us and our program, please follow the link below. We also invite you to join us in our quest, either as an active volunteer on one of our expeditions or as a contributing member by lending your support to our Oceans 911 funding drive to establish to an intelligent ecological monitoring platform (which now does not exist anywhere) to investigate and understand in detailed scientific terms the full impact of humanity on the ocean environment. The major benefit of this long term project is the preservation of our planet’s most important, largest and most fragile ecosystem. The time has come to kick-start this important endeavour.
In today’s video feature we will see how the exploration of our planet’s last great frontier is closely linked to the exploration of the vast new ocean of space.
More than 70 percent of Earth is covered in water, but we've only explored roughly 5 percent of it. We've roamed even less of our solar system. Now, armed with some of the latest advances in technology, we join scientists on a voyage into the unknown - from the far reaches of space to the extreme depths of our oceans - where new discoveries have experts questioning everything we know about the universe, and ultimately ourselves.
"Teetering here on the fulcrum of destiny stands our own bemused species. The future of the universe hinges on what we do next. If we take up the sacred fire, and stride forth into space as the torchbearers of Life, this universe will be aborning. If we carry the green fire-brand from star to star, and ignite around each a conflagration of vitality, we can trigger a Universal metamorphosis. Because of us, the barren dusts of a million billion worlds will coil up into the pulsing magic forms of animate matter. Because of us, landscapes of radiation blasted waste, will be miraculously transmuted: Slag will become soil, grass will sprout, flowers will bloom, and forests will spring up in once sterile places. Ice, hard as iron, will melt and trickle into pools where starfish, anemones, and seashells dwell — a whole frozen universe will thaw and transmogrify, from howling desolation to blossoming paradise. Dust into Life; the very alchemy of God".

Today on Cosmic Visions we take an exciting voyage into the future and explore the wonderful and exciting possibility of humanity expanding outwards from its planetary abode to make its home amongst the stars.
In “Space Colonies: Living Among the Stars” we examine the scientific basis for the growing belief that humans can and will carry our civilization far from Earth through the eyes of such visionaries as Marshal T. Savage, Robert Zubrin, Christopher McKay, Jim Benson and Gerard K O’Neill.
As we approach the fiftieth anniversary of the establishment of the Search for Extraterrestrial Intelligence (S.E.T.I.) as a bona fide branch of legitimate scientific inquiry we cannot help but wonder how "First Contact" will occur and what effect this will have on humanity.
Today we explore this exciting possibility through the vision of Dr. Carl Sagan as outlined in his first and only science fiction novel “Contact” published in 1985 and the film adaptation released twelve years later.
The novel and book both present a unique and wonderful vision of a common science fiction theme about the first meeting between humans and extraterrestrial life. Sagan expands on this theme in his novel and hints at the possibility of an even higher overarching intelligence that existed before the creation of the Cosmos and responsible for bringing into being. Unfortunately in the motion picture this was only touched upon obliquely.
Eleanor "Ellie" Arroway is the director of "Project Argus," in which scores of radio telescopes in New Mexico have been dedicated to the search for extraterrestrial intelligence (SETI).
Before long, the project does, indeed, discover the first confirmed communication from extraterrestrial beings, a repeating series of the first 261 prime numbers (a sequence of prime numbers is a commonly predicted first message from alien intelligence, since mathematics is considered a "universal language," and it is conjectured that algorithms that produce successive prime numbers are sufficiently complicated so as to require intelligence to implement them). Further analysis of the message reveals that two additional messages are embedded in the signal. One of these messages is the detailed instructions of a machine that transports professor Arroway on an incredible odyssey to the heart of the Milky Way Galaxy and a face to face encounter with the intelligent beings that sent the message.
In a kind of postscript, Ellie, acting upon a suggestion by the senders of the Message, works on a program which computes the digits of π to record lengths and in different bases. Very, very far from the decimal point (ten to the twentieth power) and in base 11, it finds that a special pattern does exist when the numbers stop varying randomly and start producing 1s and 0s in a very long string. The string's length is the product of 11 prime numbers. The 1s and 0s when organized as a square of specific dimensions form a rasterized circle.
The extraterrestrials suggest that this is an artist's signature, woven into the very fabric of space. It is another Message, one from the universe's creator. Yet the extraterrestrials are just as ignorant to its meaning as Ellie, as it could be still some sort of a statistical anomaly. They also make reference to older artefacts built from space time itself (namely the wormhole transit system) abandoned by a prior civilization. A line in the book suggests that the image is a foretaste of deeper marvels hidden even further within Pi. This new pursuit becomes analogous to SETI; it is another search for meaningful signals in apparent noise. This idea, among other plot points, was omitted from the film version.
While both the novel and film stand on their own merits one wonders if the film could have attained the same distinction as a cult classic like Stanley Kubrick’s “2001” if this latter theme were worked into the motion picture.
Today on Discovery Enterprise we are going to embark on an intergalactic odyssey to visit the hundreds of billions of galaxies that in make up our universe. This is a journey that will take us back to the dawn of time.
Today on Cosmic Visions we commemorate the memory of Carl Sagan who died an untimely death thirteen years ago today. Carl Sagan, was an astronomer, astrochemist, author, and highly successful popularizer of astronomy, astrophysics and other natural sciences. He pioneered exobiology and promoted the Search for Extra-Terrestrial Intelligence (SETI). For me personally he will always be remembered and revered as a great teacher who communicated the joys and transcendence of scientific discovery. Carl Sagan’s enduring legacy will always be linked to his ability to convey the wonders of science to the general public and his skill in inspiring the next generation of scientists. Carl Sagan’s name will also be forever linked to the greatest science television series in history – Cosmos.
Sagan made the front cover of Time Magazine (Monday October 20th, 1980) which dubbed him the “Showman of Science.” The cover story, entitled ‘The Cosmic Explainer’ by Frederic Golden contains a very good biographical sketch of Carl and appeared when his landmark documentary Cosmos graced our television screens some thirty years ago.
So in order to commemorate the thirteenth anniversary of his death we are presenting a retrospective of the very best moments and highlights of the highly acclaimed documentary series Cosmos and the A&E Channel’s profile of Carl Sagan which aired shortly after his unfortunate death. It is a very good portrayal of how a kid from Brooklyn made good and became something of a media superstar —“indeed, a supernova of sorts”. So for your perusal “Heeere's Carl, bringing you nothing less than the Cosmos.”
