 Hubblecast 71: Visible echoes around RS Puppis | File Type: video/x-m4v | Duration: 303

This episode of the Hubblecast explores striking new Hubble observations of a variable star known as RS Puppis. This star is growing brighter and dimmer as it pulsates over a period of five weeks. These pulsations have created a stunning example of a phenomenon known as a light echo, where light appears to reverberate through the foggy environment around the star.

 Hubblecast 70: Peering around cosmic corners | File Type: video/x-m4v | Duration: 462

Last month saw the inauguration of a new Hubble observing program: Frontier Fields. This will use the powerful magnifying properties of massive galaxy clusters to peer even deeper into the space around us. Hubblecast 70 takes a look at this phenomenon — known as gravitational lensing — exploring how it works, and how it can help us to uncover the secrets of the very distant Universe.

 Hubblecast 69: What has Hubble learned from star clusters? | File Type: video/x-m4v | Duration: 393

The NASA/ESA Hubble Space Telescope has observed many star clusters. As well as being scientifically interesting, these clusters produce stunning images, appearing like sparkling baubles in the sky.

 Hubblecast 68: The Hubble time machine | File Type: video/x-m4v | Duration: 447

For episode 68 of the Hubblecast, Hubble transforms into more than just a telescope — it becomes a time machine! How can Hubble "look back in time" to see the Universe as it was billions of years ago? Dr. J explores the vast scale of our Universe, explaining how Hubble can be used to grasp cosmic distances, view very distant galaxies, and even explore our own past.

 Hubblecast 67: Of galaxies and penguins — Arp 142 | File Type: video/x-m4v | Duration: 324

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.

 Hubblecast 66: Hubble uncovers the secrets of the Ring Nebula | File Type: video/x-m4v | Duration: 329

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.

 Hubblecast 65: A whole new view of the Horsehead Nebula — celebrating Hubble's 23rd birthday | File Type: video/x-m4v | Duration: 363

This episode of the Hubblecast celebrates 23 years of the NASA/ESA Hubble Space Telescope, by unveiling a beautiful and striking new image of the Horsehead nebula.

 Hubblecast 64: It all ends with a bang! | File Type: video/x-m4v | Duration: 587

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.

 Hubblecast 63: From the distant past - Hubble and art | File Type: video/x-m4v | Duration: 478

This episode of the Hubblecast explores how conceptual artist Tim Otto Roth has been inspired by scientific data from the NASA/ESA Hubble Space Telescope to create a unique work of art.

 Hubblecast 62: A spiral galaxy with a secret | File Type: video/x-m4v | Duration: 297

Despite its appearance, which looks much like countless other galaxies, Messier 106 hides a number of secrets. In this episode of the Hubblecast, Dr Joe Liske (aka Dr J) takes us on a tour of the galaxy. Thanks to a new image, which combines data from Hubble with observations by amateur astronomer Robert Gendler, the galaxy’s secrets are revealed as never before.

 Hubblecast 61: A Tour of NGC 5189 | File Type: video/x-m4v | Duration: 322

In this episode of the Hubblecast, Dr Joe Liske (aka Dr J) invites us to tour NGC 5189, a planetary nebula in our galaxy. The nebula looks like a ribbon in space, with a complex structure that comes from the dying throes of a Sun-like star at its centre.

 Hubblecast 60: Galaxy scores a bullseye | File Type: video/x-m4v | Duration: 260

Episode 60 of the Hubblecast explores NGC 922, a galaxy that has been hit square-on by another. Ripples of star-formation are still propagating out across thousands of light-years of space over 300 million years after the collision, making it a prime example of what astronomers call a collisional ring galaxy.

 Hubblecast 59: Unweaving the rainbow | File Type: video/x-m4v | Duration: 373

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.

 Hubblecast 58: Caught in the cosmic web | File Type: video/x-m4v | Duration: 410

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 found that an invisible filament of dark matter extends out of the cluster. This is our first direct glimpse of the shape of the scaffolding that gives the Universe its structure.

 Hubblecast 57: Hubble's hidden treasures unveiled | File Type: video/x-m4v | Duration: 267

In this episode of the Hubblecast, Joe Liske (aka Dr J) presents the winners of the Hidden Treasures image processing competition.
