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.
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.

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.
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.

In this episode of the Hubblecast, Joe Liske, aka Dr J, takes us on a tour of the outer reaches of the Andromeda Galaxy, the closest spiral galaxy to our Milky Way.

In this episode of the Hubblecast, Joe Liske (aka Dr J) looks at newborn stars firing out jets of matter. These jets may cast new light on how the Sun formed 4.5 billion years ago. An international team of scientists led by astronomer Patrick Hartigan of Rice University in Houston, USA, has collected enough high-resolution Hubble images over a 14-year period to stitch together time-lapse movies of these jets.

The galaxy Messier 74 lies at a distance of over 30 million light years. In this latest image from the NASA/ESA Hubble Space Telescope the enormous swirls of this stunning spiral galaxy arc across space, adorned with glowing pink regions of hydrogen gas and lit by the pale blue light of millions of newly formed stars.

Have you ever wondered why some telescopes are launched into space while others are built on remote mountain tops? What is actually the best for astronomy? Here we provide a ringside view of the fight for the elusive photons from deep space - is it a battle of the telescope giants?

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.

The NASA/ESA Hubble Space Telescope has captured a spectacular image of NGC 3603, a giant nebula hosting one of the most prominent massive young clusters in the Milky Way. This is a splendid location for continued studies of stellar birth in star forming regions. More information and credits here: http://www.spacetelescope.org/videos/html/heic0715a.html
The NASA/ESA Hubble Space Telescope has uncovered magnificent sections of the Veil Nebula - the shattered remains of a supernova that exploded some 5-10,000 years ago. The new Hubble images provide beautiful views of the delicate, wispy structure resulting from this cosmic explosion.

New Hubble observations of the massive globular cluster NGC 2808 provide evidence that it has three generations of stars instead of one as current theories predict. More information and credits here: http://www.spacetelescope.org/videos/html/heic0708a.html
In this episode of the Hubblecast, Joe Liske (aka Dr J) presents the winners of the Hidden Treasures image processing competition. In May 2012, we asked members of the public to delve into Hubble's vast science archive to uncover pictures that had never been seen outside of the scientific community — and then to try their hand at processing the scientific data into attractive images. This episode presents the top ten images from the several thousand submitted. http://www.spacetelescope.org/videos/hubblecast57a/
This joint episode of the Hubblecast and ESOcast presents Abell 2744, an unusual cluster of galaxies nicknamed "Pandora's Cluster" by the astronomers who have studied it. Looking at the galaxies, gas and dark matter in the cluster, scientists have reconstructed the series of huge collisions that created it, and have uncovered some strange phenomena never seen together before.
This episode of the Hubblecast celebrates 23 years of the NASA/ESA Hubble Space Telescope, with the unveiling of a beautiful and striking new Hubble image of the Horsehead Nebula. Our host Dr Joe Liske (aka Dr J) explains the secrets of nebulae, cosmic clouds of gas and dust that have been the subjects of some of Hubble’s most striking astronomical images. The Horsehead Nebula is one of the most distinctive, and is now shown in a whole new light thanks to a stunning new infrared image — revealing the delicate wisps of gas that are normally hidden by the thick dust that makes up the Horsehead’s famous and familiar shape.

Hubble has delivered an unrivalled snapshot of the nearby barred spiral galaxy NGC 1672. This remarkable image provides a high-definition view of the galaxy's large bar, its fields of star-forming clouds and its dark bands of interstellar dust.

An international team of astronomers using the NASA/ESA Hubble Space Telescope has discovered a ghostly ring of dark matter formed long ago during a colossal collision between two galaxy clusters. This is the first time that dark matter has been found with a distribution that differs substantially from the distribution of ordinary matter.

We live in a Universe of unimaginable scale and almost incomprehensible beauty. How is the light from the Universe transformed into the images that have inspired generations by making the Universe come to life?

Episode 66 of the Hubblecast explores the Ring Nebula (Messier 57). Although this nebula is one of the most famous objects in our skies, more than 200 years after its discovery astronomers are still unveiling some of its secrets. Credit: ESA/Hubble
