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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
