This video gives a very brief description of the Big Bang, what it could mean for the universe, and overlays a few interesting infographics over it in a fantastic animation narrated by Dr Janna Levin.

A growing number of doomsday scenarios seem to be appearing on the Internet, but do any contain scientific merit?

Have you ever pointed out how inaccurate the science is in some science fiction?

In troubled economic times, it’s often hard to convince the government to fund space science. But there’s one field of research that the public should be happy to support: keeping the Earth from being pummeled by asteroids. And there is no shortage of ideas for how to do this.

The Hubble Ultra Deep Field is an image of a small region of space in the constellation Fornax, composited from Hubble Space Telescope data in 2004. It is the deepest image of the universe ever taken, looking back approximately 13 billion years.

Showing 10,000 galaxies, the overwhelming Hubble Ultra Deep Field is the most amazing, most humbling image in history, demonstrating how tiny and precious we are. This video explains how it was taken, and shows it in three dimensions.

Speaking as both an astronomer and "a concerned member of the human race," Sir Martin Rees examines our planet and its future from a cosmic perspective. He urges action to prevent dark consequences from our scientific and technological development.

What is the mysterious "dark energy" driving space to rapidly expand? What existed before the Big Bang? Is there an origin of time? This debate from the World Science Festival talks about new advances that are shaping our understanding of the cosmic order and our place within it.
