20 June 2013: This episode of the Hubblecast explores the violent world of galactic mergers, as shown by the cosmic duo Arp 142 in a stunning new image from the NASA/ESA Hubble Space Telescope. Galaxies spend most of their life drifting through the cosmic expanse in isolation. But, every so often, two unfortunate galaxies stray a little too close to one another — as is the case with Arp 142. Showcased in a stunning new image from Hubble, these two galaxies uncannily resemble a penguin guarding its egg. The galaxies are in middle of a violent merger, with clouds of gas and dust colliding at breakneck speeds and triggering bursts of star formation.

23 May 2013: This episode 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. The Ring Nebula was discovered in the late 18th century, but its true shape and structure has remained unclear. Now, a team of astronomers has used the NASA/ESA Hubble Space Telescope, alongside existing ground-based data, to explore the Ring Nebula in depth. The astronomers wanted to better understand the nebula’s structure, evolution, physical conditions, and motion — and it turns out that the Ring Nebula is not actually very ring-shaped after all. Hubblecast 66 showcases stunning new Hubble images of this beautiful object, showing the bright, colourful centre of the nebula, and the dramatically turbulent space that surrounds it.

19 April 2013: 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.

3 April 2013: Most stars in the Universe are small and insignificant, and they will — eventually — fizzle out without much drama. But a few light up the sky when they die, and in the process, they don’t just tell us about the lives of stars: they create the building blocks of life, and help us to unravel the whole history of the Universe. These are the stars that end their lives as supernovae, explosions that are among the most violent events in the Universe. Over more than 20 years in orbit, the NASA/ESA Hubble Space Telescope has proved to be an invaluable tool with which to unveil the secrets behind these stellar remnants. Join Dr J, aka Dr Joe Liske, in this explosive episode of the Hubblecast, and discover more about the violent side of the Universe.

12 November 2012: In this episode of the Hubblecast, we do away with Hubble’s stunning pictures of the cosmos, and focus on one of the telescope’s most important — but least known — functions. Like a digital camera, Hubble’s cameras produce colour images by sampling just a handful of colours and combining them together into one picture. The detail is extraordinary — but while the colours are accurate enough for the human eye, they are not good enough for some kinds of scientific work, such as the study of distant galaxies and extrasolar planets.  For much of their research, astronomers use Hubble’s spectrometers, devices that split up light into a rainbow of component colours, to reveal many of the hidden properties of the Universe. These observing methods may not produce attractive images, but they lie behind some of the most profound science that Hubble does. In this episode, presenter Joe Liske (aka Dr …

16 October 2012: In this episode of the Hubblecast, Joe Liske (aka Dr J) shows how a team of astronomers has used Hubble and a battery of other telescopes to discover the secrets of massive galaxy cluster MACS J0717. They have discovered that an invisible filament of dark matter extends out of the cluster. This is our first direct glimpse of the scaffolding that gives the Universe its structure.

23 August 2012: 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.

23 August 2012: Hubble has made over a million observations since launch, but only a small proportion are attractive images — and an even smaller number are ever actually seen by anyone outside the small groups of scientists that publish them. But the vast amount of data in the archive means that there are still many hundreds of beautiful images scattered among the valuable, but visually unattractive, scientific data that have never been enjoyed by the public. We call these pictures Hubble’s hidden treasures, and a few months ago, we invited the public to look through Hubble’s science archive to help us find them. The response was impressive, with almost 3000 submissions. More than a thousand of these images were fully processed: a difficult and time-consuming task. We’ve already started featuring the best of these in our Hubble Picture of the Week series. And to say thanks, we’re awarding prizes for the best …

1 August 2012: In April and May, ESA/Hubble invited the public to search through the archive and uncover hidden treasures (ann1203). These are Hubble images that have never been published, and have only ever been seen by a handful of scientists up to now. The response was overwhelming: almost 3000 submissions in two categories, for basic image searching in the archive, and advanced image processing using professional software. So it’s taken some time to collect and classify all the submissions. But now it’s time to decide who gets the prizes! The judges are hard at work looking through the submissions to decide who wins the top award. But we also want the public to have a say, with a people’s choice category which anyone can vote for. You can now vote on the images in both categories: The shortlist and voting page for the advanced image processing category is here. The shortlist and …

16 July 2012: ESA’s Facebook community for the Hubble Space Telescope has recently welcomed its 100 000th member. We would like to thank all our friends for their curiosity about space, their interest in the Hubble Space Telescope and their support in sharing the wonders of the Universe with the world. Each of our Facebook friends acts as a Hubble ambassador every time they share one of our Facebook stories or images with their friends. Although it may seem like a small gesture, their efforts play a role in the bigger picture. To illustrate the importance of that role, ESA/Hubble is launching a “Hubble’s Friends” campaign. Today we have uploaded a special photo on our Facebook page, carrying the message “I’m a friend of Hubble”. From today until Sunday, 22 July, our Facebook friends can tag themselves in the image. As the number of Facebook tags per photo is limited, we have created …

28 June 2012: In this episode of the Hubblecast, Dr J (aka Dr Joe Liske) presents the latest discovery about HD 189733b, an exoplanet that has been repeatedly studied by Hubble. Observations taken in 2011 using Hubble and the Swift satellite showed a flare from the planet’s parent star scorching the upper atmosphere and driving it off into space. This is the first time that clear change has been observed in an exoplanet’s atmosphere. The observations give a tantalising glimpse of changing weather on planets outside our Solar System.
