1. Over-massive black hole in compact galaxy NGC1277

    NGC 1277 is a compact little galaxy with one of the biggest black holes known to date. Its black hole weighs 17 billion times the mass of the Sun, which is an incredulously 14% of this galaxies total mass. Most of the stars in this galaxy are strongly affected by the gravitational pull of this black hole. And the black hole in this galaxy is bigger than our solar system. The research paper is published in Nature on November 29 2012. The animation shows representative orbits of the stars in this galaxy from the dynamical model used to measure the black hole mass. The green orbit shows the orbit of the stars in the disk. The red orbit shows the strong gravitational pull near the black hole. The blue orbit is strongly influenced by the (round) dark matter halo. One second in this animation represents 22 million years of simulated time and the horizontal size of this image is 41 million lightyears (36 arcsec).

      NPR / RadioLab correspondent Robert Krulwich rockets from the edge of the Milky Way to the center of the Orion Nebula, to get a close look at a new star with planets beginning to form around it. Animator Brian Edgerton and I nested together several ultra-high-resolution images from the Hubble Space Telescope to create the "flying" effect. Robert has more cool stuff to go with the story (supernova pics, avalanches on Mars, etc) here: http://www.npr.org/templates/story/story.php?storyId=125322033

        Sometime in 2024 the Hubble Space Telescope will die unless we can figure out a way to capture it and bring it down. ;This video outlines the problem.

          Our last Transit of Venus is a film project about the Transit of Venus 2012, supported by the European Planetology Network (Europlanet, http://www.europlanet-eu.org). Please visit www.vimeo.com/channels/ourlasttransitofvenus for other related videos. A Transit of Venus is when planet Venus passes in front of the Sun as seen from the Earth. This happens at intervals of 121.5, 8, 105.5, 8, 121.5, 8, etc. years. Transits of Venus were observed in 1639, 1761 and 1769, 1874 and 1882 and in 2004. After 2012, one will have to wait until 2117 to see another one. It was realised in the past that a Transit of Venus event observed from different places on Earth could lead to a direct measurement of the size of the Solar System. The events in the 18th and 19th century led to worldwide expeditions to do exactly that. In 2004, the exercise was repeated by amateur astronomers and students. Scientists used the Transit to learn more about the atmosphere of planet Venus and about how to observe exoplanets transiting their mother stars. In 2012, similar actions will be organised all over the world. The film is in the make at the moment and we are now getting footage of the aftermath of the event, the science results and people's memories. More information on the Transit of Venus 2012 can be found on www.transitofvenus.nl, www.transitofvenus.info, http://sunearthday.nasa.gov/2011/index.php and www.imcce.fr.

                This time-lapse video uses observations from the NASA/ESA Hubble Space Telescope over a number of weeks to show the variable star RS Puppis and its environment. A stunning example of a phenomenon known as a light echo can be seen around the star, creating the illusion of gas clouds expanding out from RS Puppis.

                    This artist’s impression shows a viewpoint rising up through the atmosphere of exoplanet HD 189733b during sunrise. The colours of the blue sky and reddish star are caused by Rayleigh scattering, the same effect that produces blue skies and red sunsets on Earth. This effect is produced by haze in the upper atmosphere scattering blue light more efficiently than red. The colours in the video are derived from estimates by Frederic Pont (Exeter University, UK) and Alain Lecavelier des Etangs (IAP/CNRS, France), based on Hubble observations of HD 189733b’s atmosphere.

                      This zoom begins with an expansive view of the deep sky Hubble Space Telescope survey called GOODS North (Great Observatories Origins Deep Survey). Zooming into this field reveals a compact galactic core dubbed GOODS-N-774, the first galaxy spotted in this stage of formation — a very early stage where the dense galactic core is still furiously churning out newborn stars.
