What makes a scientific discovery really important? It's partly down to how much scientists use the discovery in subsequent work -- but it’s also partly down to what inspires their imagination. In this episode, the Hubblecast talks to some leading astronomers about their favourite Hubble discovery. Meanwhile, our presenter, Dr J, struggles to make up his mind.

Hubble's history of scientific breakthroughs has made us think afresh about our Universe. But behind the astronomical successes is a rollercoaster ride of scientific and technical challenges going back decades. The Hubblecast caught up with some of the key players in Hubble's history, including an astronaut, a Nobel Prize winner and one of the scientists who diagnosed Hubble's blurred vision in 1990. In this episode, narrated by veteran ESA scientist Bob Fosbury, they tell Hubble’s story through their personal experiences.
In early 2009, a team of astronauts visited Hubble to repair the wear and tear of twenty years of operating in a hostile environment - and to install two new instruments, the Cosmic Origins Spectrograph, and Wide Field Camera 3 - better known as WFC3.

Today's telescopes study the sky across the electromagnetic spectrum. Each part of the spectrum tells us different things about the Universe, giving us more pieces of the cosmic jigsaw puzzle. The most powerful telescopes on the ground and in space have joined forces over the last decade in a unique observing campaign, known as GOODS, which reaches across the spectrum and deep back into cosmic time.

For centuries, scientists imagined objects so heavy and dense that their gravity might be strong enough to pull anything in - including light. They would be, quite literally, a black hole in space. But it’s only in the past few decades that astronomers have conclusively proved their existence. Today, Hubble lets scientists measure the effects of black holes, make images of their surroundings and glean fascinating insights into the evolution of our cosmos.
The Hubblecast's Joe Liske (Dr J) takes us on a tour of the Tarantula Nebula. Bright star forming gas clouds, super star clusters and supernova remnants are just some of the sights in this dramatic region of the night sky.
The NASA/ESA Hubble Space Telescope is working on three of the most ambitious projects in its history just now. These multicycle treasury programs are using Hubble's unique ability to observe across the spectrum from ultraviolet, through visible, to infrared light, to build up a library of data which will serve astronomers for many years. In this podcast episode, presenter Dr J (aka Joe Liske) looks at these projects, and how they will complement the capabilities of the next great thing in space-based astronomy, the James Webb Space Telescope.
Leading up to ESO’s 50th anniversary in October 2012, we are releasing eight special ESOcasts, each a chapter from the movie Europe to the Stars — ESO’s First 50 Years of Exploring the Southern Sky. The third special episode of this series – "entitled Seeing Sharp" – presents ESO’s flagship facility: the Very Large Telescope (VLT). In this episode we discover the state-of-the-art technology behind this telescope, which has provided astronomers an unequalled view of the Universe.
