This video begins with a zoom into the constellation of Lyra, to the location of the Ring Nebula and the new composite Hubble/Large Binocular Telescope image. Then the three-dimensional model of the Ring Nebula, developed from the new observations, is explored. The main ring glows in the light of nitrogen, shown in red. That ring is filled with oxygen emission, shown in green. Perpendicular lobes are filled with the hottest emission from helium, shown in blue. Dense dark knots line the interior of the ring, and their shadows glow like spikes in Hydrogen emission, shown in red. Hydrogen emission also reveals the inner and outer halos. A circuit around the 3D model showcases the more accurate and most detailed structure that astronomers have uncovered.

This image uses a 3D effect to visualise the Ring Nebula’s structure. The brightest part of this nebula is what we see as the colourful main ring. This is composed of gas thrown off by a dying star at the centre of the nebula. More information and download-options: http://www.spacetelescope.org/videos/heic1310d/ Credit: ESA/Hubble and NASA, M.

This is an artist’s impression of the Ring Nebula’s structure, fading from the new Hubble image into a 3D visualisation. It is based on new Hubble observations of the nebula, which is actually shaped a little like a distorted doughnut. Although the centre of this doughnut may look empty, it is actually full of lower density material that stretches both towards and away from us, creating a shape similar to a rugby ball slotted into the doughnut’s central gap. The space around the nebula is turbulent and full of knotty structures that formed in the nebula's past. The brightest part of this nebula is what we see as the colourful main ring. This is composed of gas thrown off by a dying star at the centre of the nebula. More information and download-options: http://www.spacetelescope.org/videos/heic1310c/ Credit: ESA/Hubble and NASA, M.

This video zooms in on planetary nebula Messier 57, known as the Ring Nebula. The sequence begins with a view of the night sky near the constellation of Lyra. It then zooms through observations from the Digitized Sky Survey 2, and ends with a view of the nebula obtained by Hubble. The data of the region surrounding the Ring Nebula’s central region are provided by the Large Binocular Telescope Observatory.

This episode 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. The Ring Nebula was discovered in the late 18th century, but its true shape and structure has remained unclear. Now, a team of astronomers has used the NASA/ESA Hubble Space Telescope, alongside existing ground-based data, to explore the Ring Nebula in depth. The astronomers wanted to better understand the nebula's structure, evolution, physical conditions, and motion — and it turns out that the Ring Nebula is not actually very ring-shaped after all. Hubblecast 66 showcases stunning new Hubble images of this beautiful object, showing the bright, colourful centre of the nebula, and the dramatically turbulent space that surrounds it.

This animation is an artist's impression of the thin, rocky debris disc discovered around the two Hyades white dwarfs. Rocky asteroids are thought to have been perturbed by planets within the system and diverted inwards towards the star, where they broke up, circled into a debris ring, and were then dragged onto the star itself.

This animation shows the method used to probe the gas around distant galaxies. Astronomers can use tools such as Hubble’s Cosmic Origins Spectrograph (COS) to probe faint galactic envelopes by exploiting even more distant objects — quasars, the intensely luminous centres of distant galaxies powered by huge black holes. As the light from the distant quasar passes through the galaxy’s halo, the gas absorbs certain frequencies – making it possible to study the region around the galaxy in detail. This new research utilised Hubble’s COS to peer through the very thin outskirts of galactic halos, much further out than shown in this representation, to explore galactic gas at distances of up to twenty times greater than the visible size of the galaxy itself.

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.

This video shows a 3D visualisation of part of the sky in the constellation of Orion (The Hunter), showing the new infrared Hubble observations of the Horsehead Nebula (otherwise known as Barnard 33). This video presents a scientific visualisation of the Horsehead Nebula as seen in infrared light. The computer graphics model is intended to be scientifically reasonable, but not fully accurate. This new infrared image has been released to celebrate 23 years of the NASA/ESA Hubble Space Telescope. This video also uses ground-based observations from the European Southern Observatory’s Visible and Infrared Survey Telescope for Astronomy (VISTA).

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.
