How the astronomer Nicolaus Copernicus revealed the true model of the universe: 1/5

The Compass - exploring our world.

Dava Sobel uncovers the brilliance of her hero, the 16th century Polish astronomer Nicolaus Copernicus, who revealed the true model of the universe by putting the Sun, rather than the Earth, at its hub. Episode one of five.

In the Cathedral town of Frombork on the Baltic Sea in Northern Poland, we hear how he served his entire career in the church and how he kept his astronomical findings a secret, fearful of being denounced by the Catholic Church. On his deathbed, he published his life’s work, "On the Revolutions of the Heavenly Spheres".

ALMA, the remote observatory in Chile, tracks the 'radio sky': 2/5

The Compass - exploring our world.

Dava Sobel hears from telescope operators at ALMA, the remote observatory high in the Atacama Desert in Chile, talking to us with their oxygen tanks at the ready. Episode two of five.
As we hear, the ‘radio sky’ presents an alternate universe, in which the Moon and planets are barely detectable. In their place are clouds of interstellar gas and other exotic celestial sources which reveal different aspects of our history and astronomy. At ALMA, the radio astronomers do not need to wait until dark to make their observations but can work at any hour, day or night.

The James Webb Space Telescope: its journey to discover how our universe came to be. 3/5

The Compass - exploring our world.

Dava Sobel travels to Edinburgh, to catch sight of the most ambitious telescope being made. Episode three of five.

This time next year, the James Webb Space Telescope will begin its long journey to a stable orbit at a place called L-2, one million miles beyond the Moon. It will unfold the components of its huge, intricate body and look back in time, to probe events that occurred nearly 14 billion years ago.

The James Webb is a Nasa-led project, with the telescope named after the Nasa administrator who ran the space agency during the Apollo program of the 1960s. This is also a landmark collaboration between the European and Canadian Space Agencies, in all elements of its design and construction. Dava learns about the intricacies of the British component being made, the MIRI – the Mid Infrared Instrument – which will intercept invisible light waves in the infrared region of the electromagnetic spectrum, to study the earliest stars and galaxies and ultimately discover how our universe came to be.

The proposed Thirty Metre Telescope on sacred mount Mauna Kea that's causing a rift: 4/5

The Compass - exploring our world.

Science writer and author Dava Sobell travels to Hawaii to ascend mount Mauna Kea. Among the observatories on the summit is the proposed Thirty Metre Telescope. Episode four of five.
Dava discovers the plans are creating a rift between astronomers and local Hawaiians. TMT will be able to discern gases in the most remote atmospheres, which may indicate extra terrestrial life but the site is sacred for the native Hawaiian community. The story echoes the tension between science and faith that has played out for centuries.

The scientist running the Square Kilometre Array, the world's biggest telescope. Episode five of five.

The telescope's antennae spiral across the African continent. In the remote North Karoo town of Carnarvon in South Africa, the next generation of astronomers is training to run this major telescope facility.
