Sean Carroll has written a good article on the Discover Magazine site. A new paper takes data from the South Pole telescope, combines it with WMAP7 data, and looks at the implications for cosmological models. This touches on some of our favortie subjects such as dark energy and inflation. The plot showing extension of the CMBR power spectrum is impressive. Here's a good quote:

With data like these, you can do an unprecedentedly good job at constraining cosmological parameters. Here is a plot with the density of matter on the horizontal axis, and the cosmological constant on the vertical axis, using only CMB data. Show this to any remaining friends of yours who are still skeptical about the supernova observations that revealed the acceleration of the universe (if you have such friends). This is an independent detection of the cosmological constant at better than five sigma.

Since the early days of observing the cosmic microwave background (COBE), cosmology has firmly established itself as a quantitative science. The South Pole Telescope is another instrument adding to this revolution. Awesome science.

How long before we will see the first amateur cosmologists emerging? A CMB detector in your backyard, anyone? :)
