Description
VISTA, the Visible and Infrared Survey Telescope for Astronomy, was built to observe in a colour of light that the human eye cannot see – infrared. Infrared light can travel through dust clouds, allowing infrared telescopes to pull back the veils on some of the universe’s most interesting objects.

Globular clusters, spectacular assemblies of stars, sparkle like jewels at the galaxy’s edge. The smallest contain ten thousand stars, and the largest, ten million. Over time, gravity has pulled these stars into a ball shape. And now they glitter in the dusk, like dandelions gone to seed.

Description
The Milky Way is an ancient structure, forming out of the mists of the early universe. Its many brilliant vistas spark curiosity about the galaxy’s past, present and future. And as we piece together it’s dramatic story, we are also discovering our own.

Description
Almost everything in the night sky – stars, nebulas, galaxies – is beyond our physical reach, and always will be. They are also beyond our time. When we look into space, we do not see objects as they are now. We see them as they were when their light started its journey towards Earth.

The red planet looms large in our solar system … and in our dreams. It fills our minds with possibilities and promise, fuelling a hunger to embrace and explore. And though our robots play on Mars’ sandy surface, there is still much to learn safe from the higher ground of orbit.

Through early telescopes, the dying breaths of stars looked like small planet disks, and were called ‘planetary nebulas’. Clearer views painted a more interesting picture: stars seeding the universe with the complex elements needed to make all of the amazing things we see around us.

Description
Deep within galaxies lie wispy, luminous clouds called nebulas. Observed from a great distance, nebulas appear still and calm. Up close, they are as noisy and active as any nursery -- soaked with radiation and beset by fierce winds. It is in a nebula that a star’s life story begins.

The number of New Zealanders involved at the cutting edge of global astronomical research is impressive indeed-and the potential of the international projects being undertaken in that country is mind-boggling. In this episode, viewers will look upwards-way, way up, beyond the clouds, the stars, and our own galaxy-to see just what it is that we already know and what we have yet to discover about the science of space.

If technology, cost, and terrain permitted, scientists seeking key data on stars in our galaxy would have loved to construct a behemoth 330-meter-wide telescope atop Mount Wilson, just northeast of Los Angeles. Instead, they arranged six smaller telescopes over an identical area, synchronizing the light to achieve an equally superlative resolution. Called the Center for High Angular Resolution Astronomy (CHARA), the array uses the technique of interferometry...
