New information obtained by scientists using a 10-meter telescope located in Antarctica has strengthened the most widely accepted explanation for the mysterious force that is behind the increasingly rapid expansion of the universe.

Pulsars, superdense neutron stars, are perhaps the most extraordinary physics laboratories in the Universe. Research on these extreme and exotic objects already has produced two Nobel Prizes.

Astronomers are building a virtual telescope as big as our planet that will capture the first ever picture outlining an enormous black hole within our galaxy.

At the beginning of each year, master of ceremonies for the science website Edge.org John Brockman asks his cadre of world-renowned thinkers to reply to a single question of eminent significance.
