When you hear the name “Hubble”, you probably think of the NASA/ESA Hubble Space Telescope. But, decades before the Hubble Space Telescope, Dr Edwin Powell Hubble revolutionised the field of astronomy. In the newest Hubblecast, we take a look at the life and work of this brilliant American astronomer for whom the Hubble Space Telescope is named.
Using images from the NASA/ESA Hubble Space Telescope and ESO’s Very Large Telescope, astronomers have discovered unique and totally unexpected structures within the dusty disc around the star AU Microscopii
Before NASA’s New Horizons probe flew past Pluto in July 2015, almost all of the information scientists had about this mysterious dwarf planet came from observations made by Hubble. In the newest episode of the Hubblecast, we present Hubble’s discoveries in the Pluto system and explore how Hubble will continue to advance knowledge of this distant, icy world following New Horizons’ flyby.

To celebrate Hubble's 25th birthday ESA/Hubble asked the public to produce and submit short videos illustrating how Hubble has inspired them. This new Hubblecast episode presents the two winning videos. The episode also introduces us to the creators of the videos and they explain how they produced the videos and the inspiration for creating them.
This Hubblecast explores the new image of star cluster Westerlund 2, taken by the NASA/ESA Hubble Space telescope and released to celebrate its 25th year in orbit.
As Hubble enters its 25th year in orbit, with celebrations planned around the world for its anniversary on 24 April 2015, this Hubblecast celebrates the relationship the telescope will have with its future colleague, the James Webb Space Telescope.
The NASA/ESA Hubble Space Telescope has revisited one of its most iconic and popular images: the Eagle Nebula’s Pillars of Creation. This time Hubble has not just one image for us, but two: as well as the new visible-light image the telescope used infrared light to produce a second breathtaking picture of the region. Between them these images show the pillars in more detail than ever before. In this Hubblecast we explore the different ways in which Hubble, and other telescopes, have captured this iconic object.
Hubble has achieved an extraordinary amount in its lifetime and 2015 will mark 25 years since its launch. The year 2015 will be filled with Hubble-related activities for you to enjoy and, most importantly, get involved with. In this Hubblecast we look back at some of the ways in which you have shown your appreciation for Hubble in the past and let you in on what the Hubble 25 celebrations have to offer. More information on the 25th anniversary can be found on the dedicated web pages.
New observations of four globular clusters in the Fornax dwarf galaxy have called into question one of the leading theories about how these clusters form. In this episode we explain the mystery behind these objects and how it is deepened by these new findings.

In the summer of 2014 we asked the public to send us their Hubble- and astronomy-related questions, and the response was incredible! In this episode Dr J answers a selection of the questions about science related to Hubble. These range from questions about what Hubble has achieved within the Solar System, to the science it has uncovered at the very edge of the observable Universe. In this episode Dr J explains some of the key concepts, and biggest misconceptions, about the Universe we live in.
Last month we asked the public to send us their Hubble- and astronomy-related questions, and the response was incredible! In this episode Dr J answers a selection of the questions that were specifically about Hubble itself. These range from where Hubble is and how it avoids crashing into space debris, to what the future holds for Hubble, how its life will end, and what will take its place. Watch out for the next episode in which the more science-related questions will get their turn.
This Hubblecast tells the story of what happens to Hubble in the mysterious region known as the South Atlantic Anomaly. Credits and more information: http://www.spacetelescope.org/videos/hubblecast77a/
This Hubblecast explores the ‘beads on a string’ star formation found between two merging elliptical galaxies in the cluster known as SDSS J1531+3414. Credits and more information: http://www.spacetelescope.org/videos/heic1414a/
This new Hubblecast episode looks at starburst dwarf galaxies in a time when most of the stars in the Universe were formed. New NASA/ESA Hubble Space Telescope observations show that dwarf galaxies played a bigger role than expected in the early history of the Universe. This episode looks at the dwarf galaxies that form stars in sudden bursts, explores just how rampantly they are creating new stars and unravels when, where and how the stars in our Universe formed.

In April of this year, the NASA/ESA Hubble Space Telescope will be celebrating 24 years of observing. To celebrate this milestone, the observatory is releasing a brand new image of part of NGC 2174, otherwise known as the Monkey Head nebula. This new Hubblecast episode showcases this beautiful image, which views a colourful region filled with young stars embedded within bright wisps of cosmic gas and dust.
The newest episode of the Hubblecast showcases striking new observations of a spiral galaxy moving through the heart of a galaxy cluster named Abell 3627. This cluster is violently ripping the spiral’s entrails out into space, leaving bright blue streaks as telltale clues to this cosmic crime. Credit: ESA/Hubble
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.
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.
