From a distance, our galaxy would look like a flat spiral, some 100,000 light years across, with pockets of gas, clouds of dust, and about 400 billion stars rotating around the galaxys center. Thick dust and blinding starlight have long obscured our vision into the mysterious inner regions of the galactic center. And yet, the clues have been piling up, that something important, something strange is going on in there. Astronomers tracking stars in 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.
From a distance, our galaxy would look something like this.
A flat spiral, some 100,000 light years across, with pockets of gas, clouds of dust, and about 400 billion stars rotating around the galaxy’s center.
That center — bulging up and out of the galactic disk — is tightly packed with stars.
Thick dust and blinding starlight have long obscured our vision into the mysterious inner regions of this so-called “bulge.”
And yet, the clues have been piling up, that something important…something strange… is going on in there.
A NASA video from a time of great optimism about space exploration. The Apollo missions were completed and the Space Shuttle program was underway. How soon before cheap and frequent flights to space would allow the construction of O’Neal colonies and mining camps on the Moon? This visionary approach calls for tiered greenhouses in space and unlimited solar power beamed back to Earth… all before the year 2000!

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? If things dont work out on this planet Or if our itch to explore becomes unbearable at some point in the future Astronomers have recently found out what kind of galactic real estate might be available to us. Well have to develop advanced transport to land there, 20 light years away. The question right now: is it worth the trip?
If things don’t work out on this planet…
Or if our itch to explore becomes unbearable at some point in the future…
Astronomers have recently found out what kind of galactic real estate might be available to us.
We’ll have to develop advanced transport to land there, 20 light years away…. But that’s for later.
The question right now: is it worth the trip? The destination is a star that you can’t see with your naked eye, in the southern constellation Libra, called Gliese 581.
Okay, this must be a spoof of all the 2012 craziness. Our team has accidentally run across a secret government video tape that tells the real story behind 2012. An Alien Civilization parked around the planet Saturn is spreading conspiracy theories to distract Earthlings from their ultimate mission: to take control of the Galaxy. Will ordinary humans find out in time?
The greatest feel-good story in science today. The unstoppable rover Opportunity continues to roll around on the Red Planet, checking on craters and routing out rocks. A nine month mission has now stretched to six years. Now, this amazing robot is about to make tracks to a distant crater and one of the most amazing destinations of all. From NASA JPL.
This video is an adaptation of the breezy Science on a Sphere production by supremely talented members of NASA’s Scientific Visualization Studio. This video explores Jupiter’s role as the 800 pound gorilla of our solar system, with stops on its fascinating moons and the big red spot. Additional video from NASA JPL and ESA Hubble.
Pandora is the idyllic blue world featured in the movie Avatar. Its location is a real place: Alpha Centauri, the nearest star to our Sun and the most likely destination for our first journey beyond the solar system.
Remarkably, it’s anti-matter, the science fiction fuel of choice that could take us there. Normally, it’s only created in powerful jets that roar out of black holes. We can now produce small quantities in Earth-bound particle colliders. Will we journey out only to plunder other worlds? Or will we come in peace? The answer may depend on how we see Earth at that time in the distant future.
The year is 2154. Our planet has been ruined by environmental catastrophe. In the movie Avatar, greedy prospectors from Earth descend on the world of an innocent hunter-gatherer people called the Na’vi.
Their home is a lush moon far beyond our solar system called Pandora. Could such a place exist? And could our technology… and our appetite for exploration… one day send us hurtling out to reach it?
