Flying through the Young Star Cluster Westerlund 1 (Artist's Impression) [HD]
In this video we fly through the young star cluster Westerlund 1 and close in on the strange magnetar that lies within it. This remarkable cluster contains hundreds of very massive stars, some shining with a brilliance of almost one million suns. European astronomers have for the first time demonstrated that the magnetar — an unusual type of neutron star with an extremely strong magnetic field — was formed from a star with at least 40 times as much mass as the Sun. About the Object Name: Westerlund 1 Data: http://simbad.u-strasbg.fr/simbad/sim-id?Ident=Westerlund+1 Type: • X - Star Clusters Facility: Very Large Telescope Related releases "Magnetar Formation Mystery Solved?": http://www.eso.org/public/news/eso1415/ Magnetars are the bizarre super-dense remnants of supernova explosions. They are the strongest magnets known in the Universe — millions of times more powerful than the strongest magnets on Earth. A team of European astronomers using ESO's Very Large Telescope (VLT) now believe they've found the partner star of a magnetar for the first time. This discovery helps to explain how magnetars form — a conundrum dating back 35 years — and why this particular star didn't collapse into a black hole as astronomers would expect.

Astronomers Challenge Current Theories": http://www.eso.org/public/news/eso1034/ Using ESO's Very Large Telescope, European astronomers have for the first time demonstrated that a magnetar — an unusual type of neutron star — was formed from a star with at least 40 times as much mass as the Sun. The result presents great challenges to current theories of how stars evolve, as a star as massive as this was expected to become a black hole, not a magnetar. This now raises a fundamental question: just how massive does a star really have to be to become a black hole?

Orion Nebula and VISTA telescope views of the Orion Nebula
Orion Nebula and VISTA telescope views of the Orion Nebula: The Orion Nebula reveals many of its hidden secrets in a dramatic image taken by ESO's new VISTA survey telescope. VISTA — the Visible and Infrared Survey Telescope for Astronomy — is the latest addition to ESO's Paranal Observatory. It is the largest survey telescope in the world and is dedicated to mapping the sky at infrared wavelengths. The telescope's huge field of view can show the full splendour of the Orion Nebula and VISTA's infrared vision also allows it to peer deeply into dusty regions that are normally hidden and expose the curious behaviour of the very active young stars buried there. The Orion Nebula (also known as Messier 42, M42, or NGC 1976) is a diffuse nebula situated south of Orion's Belt in the constellation of Orion (from temperate zones in the Northern Hemisphere, the nebula appears below the Belt of Orion; from temperate zones in the Southern Hemisphere the nebula appears above the Belt). It is one of the brightest nebulae, and is visible to the naked eye in the night sky. M42 is located at a distance of 1,344 ± 20 light years[3][6] and is the closest region of massive star formation to Earth. The M42 nebula is estimated to be 24 light years across. It has a mass of about 2000 times the mass of the Sun. Older texts frequently refer to the Orion Nebula as the Great Nebula in Orion or the Great Orion Nebula.[7] The Orion Nebula is one of the most scrutinized and photographed objects in the night sky, and is among the most intensely studied celestial features.[8] The nebula has revealed much about the process of how stars and planetary systems are formed from collapsing clouds of gas and dust. Astronomers have directly observed protoplanetary disks, brown dwarfs, intense and turbulent motions of the gas, and the photo-ionizing effects of massive nearby stars in the nebula.

Accelerating Expansion of the Universe: Universe Expanding Ever-Faster
Accelerating Expansion of the Universe: Universe Expanding Ever-Faster
Accelerating Expansion of the Universe: Universe Expanding Ever-Faster In the past two decades, astronomers have made a truly revolutionary discovery: that the cosmos is not only expanding, but is doing so at an ever-faster rate. The discovery of the accelerated expansion of the Universe was awarded the 2011 Nobel Prize in Physics. The accelerating universe is the observation that the universe appears to be expanding at an increasing rate. In formal terms, this means that the cosmic scale factor a(t) has a positive second derivative,[1] so that the velocity at which a distant galaxy is receding from us should be continuously increasing with time.[2] In 1998, observations of type Ia supernovae also suggested that the expansion of the universe has been accelerating[3][4] since around redshift of z~0.5.[5] The 2006 Shaw Prize in Astronomy and the 2011 Nobel Prize in Physics were both awarded to Saul Perlmutter, Brian P. Schmidt, and Adam G. Riess, who in 1998 as leaders of the Supernova Cosmology Project (Perlmutter) and the High-Z Supernova Search Team (Schmidt and Riess) discovered the accelerating expansion of the Universe through observations of distant ("High-Z") supernovae.[6][7] From Wikipedia: en.wikipedia.org/wiki/Accelerating_universe [1] Jones, Mark H.; Robert J.

This sequence starts with a wide-field view of the prominent constellation of Leo (The Lion). As we zoom in many fainter stars become visible as well as a few of the many galaxies in this part of the sky. We gradually close in on the most distant quasar found so far. The final view, combining images taken in both visible and infrared light, shows the very faint quasar, which is powered by a black hole with a mass two billion times that of the Sun, as a faint red dot.

New Exoplanets Discovered: Fifty New Exoplanets Found with HARPS
New Exoplanets Discovered: Fifty Exoplanets Found with HARPS: Astronomers using a new precision spectrograph instrument known as High Accuracy Radial Velocity Planet Searcher (HARPS) have today announced more than fifty newly discovered planets around other stars. Among these are many rocky planets not much heavier than the Earth. One of them in particular seems to orbit in the habitable zone around its star. In ESOcast 35 we look at how astronomers discover these distant worlds and what the future may hold for finding rocky worlds like the Earth that may support life. The High Accuracy Radial Velocity Planet Searcher (HARPS2002-2014) was a high-precision echelle spectrograph installed in 2002 on ESO's 3.6m telescope at La Silla Observatory in Chile. Since first operation it has discovered over 130 planets. The first light was achieved in February 2003. It is a second-generation radial-velocity spectrograph, based on experience with the ELODIE and CORALIE instruments.[1] From Wikipedia: en.wikipedia.org/.../High_Accuracy_Radial_Velocity_Planet_.

This sequence starts with a broad view of the southern skies. We close in on an apparently empty region in the faint constellation of Sculptor. As we zoom in further we can start to make out a faint cloud of very distant galaxies. In the final sequence, based on images from the ESO VLT and the NASA/ESA Hubble Space Telescope, this object is revealed to be a spectacularly rich merging cluster of galaxies called Abell 2744, and nicknamed Pandora's Cluster.

Nel meteorite, micro-tunnel e sferule ricche di carbonio, lo farebbero assomigliare particolarmente ad alcune rocce terrestri alterate dall'acqua e da forme di vita. http://curator.jsc.nasa.gov/antmet/mmc/Y000593.pdf http://www.jpl.nasa.gov/news/news.php?release=2014-065 http://gaianews.it/scienza-e-tecnologia/marte-e-il-meteorite-yamato-tracce-della-vita-di-milioni-di-anni-fa-52496.html http://www.corriere.it/scienze/14_marzo_07/meteoriti-marte-trovato-cratere-origine-6b210686-a615-11e3-b663-a48870b52ff3.shtml http://www.natureworldnews.com/articles/6204/20140228/tiny-tunnels-martian-meteorite-yamato-000593-hint-life-mars.htm http://www.jpl.nasa.gov/news/news.php?release=2014-065&1 http://www.lpi.usra.edu/meteor/metbull.php?code=24355 http://www.nhm.ac.uk/research-curation/research/projects/metcat/search/detail.dsml?Key=Y299.000593&passed;_Name=Yamato%20000593&index;=&sort;=Name&Grp;=SNC&beginIndex;=33&listPageURL;=list.dsml%3Fsort%3DName%26beginIndex%3D30%26Grp%3DSNC& http://online.liebertpub.com/doi/abs/10.1089/ast.2011.0733 http://www.space.com/24834-strange-mars-meteorite-life-evidence-debate.html http://articles.adsabs.harvard.edu/cgi-bin/nph-iarticle_query?bibcode=2003AMR....16...13I&db;_key=AST&page;_ind=0&plate;_select=NO&data;_type=GIF&type;=SCREEN_GIF&classic;=YES- published: 10 Mar 2014
