Starstuff With Stuart Gary

Glaciers on the surface of Pluto could explain the mysterious frozen world's youthful skin. Also: most Earth-like planet ever found orbiting a Sun-like star, and more support for the Standard Model of particle physics.

Icy mountain ranges and vast frozen plains dominate a geologically young surface on Pluto. Also; dead galaxies saved by dark matter, and a new 100-million-dollar effort to try an answer that eternal question: are we alone in the universe?

New Horizons becomes the first spacecraft to visit Pluto. Also monster black hole grows surprisingly faster than its ancient galaxy, and physicists at CERN discover a new particle: the 'pentaquark'.

Despite a glitch earlier this week, New Horizons is on course for its historic rendezvous with Pluto. Also; mystery circles on Pluto's surface baffle scientists, and new calculations claim an earlier more violent end to the universe.

Astronomers discover a planet that looks like a comet. Also; how magnetic fields could help to form a galaxy's spectacular spiral arms, and Earth hit by two geomagnetic storms in a week.

Astronomers observe what could be some of the first stars to form after the Big Bang. Also: evidence for current volcanism on Venus, and new signs of methane from Mars.
