Terraforming Mars

Could human settlements on Mars become reality as early as 100 years from now? Artificial micro organisms created with the latest techniques in synthetic biology could be used to produce resources such as iron, energy, and food directly on the planet itself. What would this new "Earth" look like?

Knowing without Seeing - The Science of Black Holes

Einstein, Oppenheimer, and other physicists and astronomers wrestled with the concept of Black Holes. With relentlessly powerful gravitational pull, black holes suck in anything that comes near them, but do they? As the study of black holes progresses, science finds more mysteries than solutions.

Monster Black Holes

There are Black Holes, and then there are Monster Black Holes -- containing several million to ten billion times the mass of our Sun! They've been discovered in the center of many galaxies. But they don't just absorb everything around them...in fact, they may be key to forming new galaxies.

Our Extraordinary Sun

Telescopes on six solar observation satellites are currently monitoring the sun. The satellites include Japan's Hinode and the SDO developed by the United States. Solar activity (flares, sunspots) is at its lowest since modern observation began - what implications does this have for our Earth?

Saturn's Moon Titan - Another Earth?

Even with a surface temperature of -180C, Saturn's moon, Titan, could be another Earth. There's evidence of dunes made of quantities of organic material that could contain the building blocks for DNA. Astrobiologists are conducting studies on the possibility that life could be present on Titan.

Misconceptions About the Universe

The expanding universe is a complicated place. During inflation the universe expanded faster than light, but that's something that actually happens all the time, it's happening right now. This doesn't violate Einstein's theory of relativity since nothing is moving through space faster than light, it's just that space itself is expanding such that far away objects are receding rapidly from each other. Common sense would dictate that objects moving away from us faster than light should be invisible, but they aren't. This is because light can travel from regions of space which are superluminal relative to us into regions that are subluminal. So our observable universe is bigger than our Hubble sphere - it's limited by the particle horizon, the distance light could travel to us since the beginning of time as we know it.

Planets from Hell

We once thought that our solar system was unique: The only place you could find planets in the entire Universe. Now we know better. For the last twenty years we have been discovering planets at an amazing rate, but they are nothing like we expected. These are truly wild worlds, a collection of monsters. From deep-frozen, toxic snowballs, to scorched and boiling nightmares: Every one is worlds apart from the habitable paradise we know and love here on Earth. Having so far only discovered this zoo of planetary oddballs we must face the question: Is every planet out there a planet from hell?
