Summary: The latest news about astronomy, space and the NASA/ESA Hubble Space Telescope presented in High Definition is only for devices that play High Definition video (not iPhone or iPod).

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.
In this episode of the Hubblecast, Joe Liske (aka Dr J) presents the winners of the Hidden Treasures image processing competition.
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.
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.
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.
Gearing up for the 20th anniversary of the legendary space observatory, Dr. J takes a look at the story of the NASA/ESA Hubble Space Telescope. Born of an ambitious idea, it took decades for Hubble to become a reality. The project was complex and often faced huge setbacks but, ultimately, the powerful telescope took to the skies aboard the Space Shuttle Discovery on 24 April 1990.
Hubble has snapped a spectacular view of M66, the largest "player" of the Leo Triplet, and a galaxy with an unusual anatomy: it displays asymmetric spiral arms and an apparently displaced core. The peculiar anatomy is most likely caused by the gravitational pull of the other two members of the trio.
In January and March 2009, researchers using Hubble took advantage of a rare opportunity to record Saturn when its rings are edge-on, resulting in a unique movie featuring both of the giant planet's poles. Saturn is only in this position every 15 years or so and this favourable orientation has allowed a sustained study of the two beautiful and dynamic aurorae, Saturn's own northern and southern lights.
Visible to the naked eye, only 1500 light-years from Earth, the great Orion Nebula has been known and revered since ancient times. A popular target of Hubble, researchers have now identified 42 new discs within it that could be the beginnings of new planetary systems like our own.
