The Future of the Milky Way

Today on Discovery Enterprise we explore the future fate of our home galaxy – The Milky Way.


The Milky Way Galaxy, commonly referred to as just the Milky Way, or sometimes simply as the Galaxy, is the galaxy in which the Solar System is located. The Milky Way is a barred spiral galaxy that is part of the Local Group of galaxies. It is one of billions of galaxies in the observable universe. Its name is a translation of the Latin Via Lactea, referring to the pale band of light formed by stars in the galactic plane as seen from Earth.

Enjoy this Discovery Channel Documentary about the past, present and the future of our galaxy.

The Universe – Total Eclipse


Today on Discovery Enterprise we present episode seven of the fifth season of the History Channel’s outstanding documentary series – The Universe.


In this instalment we look examine an astronomical phenomenon that has inspired awe and wonder throughout the ages – The Total Solar Eclipse.

Once they were dreaded and thought to be dragons eating the sun but, modern science has dispelled mythology and we now look forward to total Solar Eclipses as one of the most spectacular phenomena in the heavens.

A look at the movements of the Earth, the sun and the moon during solar and lunar eclipses; how humans, if alone in the universe, may be the only intelligent creatures to witness these events; and how astronomers discover planets in other star systems that partially eclipse their stars.


Planets from Hell


Today on Discovery Enterprise we are going to explore some of the most hellish exosolar planets discovered to date.

Since 1995, astronomers have announced the confirmed detections of four hundred and ninety such planets.


Planets from Hell tells the intriguing and exciting story of the discovery of these hostile new worlds and explores the tantalizing possibility of one day finding a planet like Earth.

The Universe – Asteroid Attack

Today on Discovery Enterprise we present the sixth episode of the fifth season of the highly acclaimed documentary series “The Universe” currently airing on the History Channel.


The latest instalment of the series looks at the asteroids and the impact they have or had on life now and before. What can spacecraft tell us about these vermin roaming through the solar system? Will human civilization one day colonize the Asteroids and use them to voyage to the stars?


We have all heard of massive boulders hurtling toward our planet, but could we be heading straight into one instead? Find out whether President Obama is sending the next manned space mission to an asteroid.

Author’s Note: In the past year there have been three separate impact events on Jupiter.

The Seven Wonders of the Solar System

Today on Discovery Enterprise we present the fifth season opening documentary of the History Channel’s highly acclaimed documentary series The Universe with a grand tour highlighting the magnificent “Seven Wonders of the Solar System”.


In this newest instalment of the Universe we take a close look at seven of the most astonishing wonders of our solar system, such as the geysers of Enceladus; Saturn’s majestic rings; Jupiter’s awe inspiring Great Red Spot; and scale the heights of Olympus Mons on Mars.

Cosmic Odyssey – Twenty-first Century Cosmos

Today on Discovery Enterprise we present another exciting episode from the documentary series “Cosmic Odyssey narrated by Star Trek’s William Shatner.

Our perception of the universe has changed dramatically over the centuries from thoughts of a starry, unknown realm to knowledge of the countless galaxies that surround us, yet the scale of the cosmos remains a mystery. How old is the universe? How much matter and energy does the universe contain?


“Twenty-first Century Cosmos” probes these central questions of cosmology with international astronomers to refine our understanding of how stars and galaxies are formed, if the universe is flat or curved, and how and why the universe will continue to expand.

Cosmic Odyssey – Stellar Evolution

Each of us, in the immortal words of the American poet Walt Whitman, “…are the journeywork of the stars, no less than the leaves of grass.” As Carl Sagan would put it later in the twentieth century – “Our lives, our past and our future are tied to the sun, the moon and the stars… We humans have seen the atoms which constitute all of nature and the forces that sculpted this work… and we, who embody the local eyes and ears and thoughts and feelings of the cosmos, have begun to wonder about our origins… star stuff contemplating the stars, organized collections of ten billion billion billion atoms, contemplating the evolution of nature, tracing that long path by which it arrived at consciousness here on the planet earth… Our loyalties are to the species and to the planet. Our obligation to survive and flourish is owed not just to ourselves but also to that cosmos ancient and vast from which we spring”.


Today on Discovery Enterprise we trace this stellar legacy with a documentary series that has not graced our illustrious pages since last December. We present Cosmic Odyssey narrated by the veteran actor William Shatner.

If we could watch the night sky over a period of millions of years, we would witness the stars undergo an astonishing sequence of transformations. Thanks to a new generation of telescopes we can follow the unfolding life story of a star from the moment of its first gestation as a prostellar object forming in a majestic cosmic nebula, through to the moment of birth.

Astronomers have developed the telescopic equivalent of ultrasound, a camera sensitive to infrared light which monitors prenatal suns incubating inside clouds of hydrogen gas and the first fleeting moments of a newborn protostar as it announces its arrival on the cosmic scene with a copious flux of ultraviolet energy.

The science of our epoch has allowed us to follow the life after death of a star and follow its reincarnation from the moment of its tumultuous death to the formation of new generations of stars, and at least in our nook of the galaxy, the formation of planets, life and sentience.
