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. 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.

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.

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.More information: http://www.spacetelescope.org/videos/heic1220a/Credit:ESA/HubbleVisual design and editing: Martin KornmesserWeb and technical support: Mathias Andre and Raquel Yumi ShidaWritten by: Oli UsherNarrator: Sara Mendes da CostaPresented by: Dr Joe Liske (Dr J)Images: NASA, ESA,, Digitized Sky Survey 2Music: John StanfordDirected by: Oli UsherExecutive producer: Lars Lindberg Christensen

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 J) and Hubble astronomer Bob Fosbury give a introduction to spectroscopy using Hubble, how it works, and what it’s for.More information and download-options:spacetelescope.org/videos/hubblecast59a/Credit:ESA/HubbleVisual design and editing: Martin KornmesserWeb and technical support: Mathias Andre and Raquel Yumi ShidaWritten by: Oli UsherInterviews: Oli UsherFilming: Herbert ZodetPresented by: Joe Liske (Dr J), with Bob FosburyNarrator: Sara Mendes da CostaImages: NASA, ESA, Bob Fosbury, Martin KornmesserVisualisations and animations: Luis Calçada, Martin Kornmesser, André Roquette.Music: Steve BuickDirected by: Oli UsherCinematography: Peter Rixner (perix.de)Executive producer: Lars Lindberg Christensen

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.More information and download-options: http://www.spacetelescope.org/videos/heic1215a/Credit:ESA/HubbleVisual design and editing: Martin KornmesserWeb and technical support: Mathias Andre and Raquel Yumi ShidaWritten by: Oli UsherPresented by: Joe Liske (Dr J)Images: NASA, ESA, Harald Ebeling (University of Hawaii at Manoa), Jean-Paul Kneib (LAM)Visualisations: Luis CalçadaFootage: Herbert ZodetMusic: Toomas ErmDirected by: Oli UsherCinematography: Peter Rixner (www.perix.de), Herbert ZodetExecutive producer: Lars Lindberg Christensen

In this episode of the Hubblecast, scientists Jay Anderson and Roeland van der Marel show how they have used Hubble observations to predict the future of the Andromeda Galaxy and the Milky Way.Projecting the motion of Andromeda’s stars over the next 8 billion years, the astronomers now know the path that galaxy is taking through space. And it’s heading straight for us! Computer simulations based on Hubble observations show how the two galaxies will crash together in around 4 billion years’ time.Credit:ESA/Hubble & NASA/STScIVisual design and editing: Martin KornmesserWeb and technical support: Raquel Yumi Shida and Mathias AndréWritten by: Oli UsherInterviews: Mary Estacion (NASA/STScI)Animations: Frank Summers (NASA/STScI), Greg Bacon (NASA/STScI)Narration: Dr J (Joe Liske)Images: NASA & ESAMusic: John Stanford from Deep SpaceDirected by: Oli UsherExecutive producer: Lars Lindberg ChristensenMore information and download-options:http://spacetelescope.org/videos/hubblecast55a/

To celebrate the 22nd anniversary of the NASA/ESA Hubble Space Telescope this month, episode 54 of the Hubblecast gives a slideshow of some of the best images from over two decades in orbit, set to specially commissioned music.More information: http://www.spacetelescope.org/videos/heic1206a/Credit:ESA/HubbleVisual design and editing: Martin KornmesserWritten by: Oli UsherImages: NASA, ESAMusic: Toomas ErmDirected by: Oli UsherWeb and technical support: Raquel Yumi ShidaExecutive producer: Lars Lindberg Christensen

Over two decades in orbit, the Hubble Space Telescope has made a huge number of observations. Every week, we publish new ones on the Hubble website. But hidden in Hubble’s huge data archives are some truly breathtaking images that have hardly ever been seen by anyone.In this episode, Dr J, aka Dr Joe Liske, explains what all this data is, what it’s for, and how you can take a look at it yourself.More information: http://www.spacetelescope.org/videos/hubblecast53a/

In this episode of the Hubblecast, we take a tour of the compact star-forming region Sh 2-106. Its hourglass shape is caused by the final, violent phases of a star’s formation in the middle of the gaseous nebula. This episode explains some of the science behind Hubble’s observations and brings them to life with detailed 3D computer visualisations.Find out how to view and contribute subtitles for the Hubblecast in multiple languages, or translate this video on dotSUB.More information and download-options:http://spacetelescope.org/videos/heic1118a/Credit:Visual design and editing: Martin KornmesserWeb and technical support: Lars Holm Nielsen and Raquel Yumi ShidaWritten by: Oli Usher and Bárbara FerreiraNarration: Joe Liske (Dr J)Images: NASA, ESAAnimations: Greg Bacon (STScI), Martin Kornmesser (ESA/Hubble)Music: Zero ProjectDirected by: Oli UsherExecutive Producer: Lars Lindberg Christensen

In episode 49 of the Hubblecast, Dr Joe Liske (aka Dr J) asked viewers to send in their questions about astronomy and the NASA/ESA Hubble Space Telescope. In episode 50, Dr J picks his favourite few questions from the hundreds that were sent in.More information: http://www.spacetelescope.org/videos/hubblecast50a/

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.Credits and more information are available on: http://www.spacetelescope.org/videos/heic1113a/

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.More information: http://www.spacetelescope.org/videos/heic1111a/

The Hubblecast's Dr J, aka Joe Liske, takes us on a tour of Centaurus A, a bright and dusty galaxy in the Southern sky. Hubble’s observations are the most detailed ever made of this galaxy.More information: http://spacetelescope.org/videos/heic1110a/

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.Credits and download options (many formats available) are on: http://www.spacetelescope.org/announcements/ann1109/
