 James Webb Space Telescope Huge strides in Big Bang cosmology have been made since the late 1990s as a result of major advances in telescope technology, as well as the analysis of data from satellites such as COBE, the Hubble Space Telescope, and Wilkinson Microwave Anisotropy Probe (WMAP). A more powerful, higher resolution telescope, the James Webb Space Telescope, scheduled to launch in 2013, will replace Hubble and study the epoch of reionisation, some one billion years after the big bang, a theory that was proven by Bell Labs scientists in the early 1960s. If you are as excited about this topic as I am, you need to read “Three Degrees Above Zero” by Peter L. Bernstein.  Some of the designs for new telescopes are incredible. The picture shows the E-ELT, one of the new designs of Extremely Large Telescopes (anything over 20m in diameter). The small white shape in the bottom left is a car! The awesome James Webb Space Telescope will launch in 2013 to replace the Hubble Telescope. Its mirror and tennis court-sized sunshield unfold in space once it reaches its home orbiting L2, some 1.5 Million km from Earth. ALMA, LOFAR and SKA will links tens or even thousands of smaller radio telescopes together as one massive array, stretching out across continents. The next decade will truly be a revolution in the devices astronomers use to study the sky.
