eso0847 - Astronomers Dissect a Supermassive Black Hole with Natural Magnifying Glasses eso0847 — Science Release 12 December 2008 Combining a double natural "magnifying glass" with the power of ESO's Very Large Telescope, astronomers have scrutinised the inner parts of the disc around a supermassive black hole 10 billion light-years away. They were able to study the disc with a level of detail a thousand times better than that of the best telescopes in the world, providing the first observational confirmation of the prevalent theoretical models of such discs. The team of astronomers from Europe and the US studied the "Einstein Cross", a famous cosmic mirage.

Astronomy Picture of the Day Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2017 February 24 NGC 3621: Far Beyond the Local Group Image Credit & Copyright: Processing - Robert Gendler, Roberto Colombari Data - Hubble Legacy Archive, European Southern Observatory, et al.

European Homepage 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. Welcome to the Hubblecast! Hubblecast features news and Images from the NASA/ESA Hubble Space Telescope. The importance of stupidity in scientific research I recently saw an old friend for the first time in many years. We had been Ph.D. students at the same time, both studying science, although in different areas. She later dropped out of graduate school, went to Harvard Law School and is now a senior lawyer for a major environmental organization. At some point, the conversation turned to why she had left graduate school. To my utter astonishment, she said it was because it made her feel stupid.

History of Space Exploration History of Space Exploration There are things that are known and things that are unknown; in between is exploration. -Anonymous Teardrop from Heaven: Aurora Australis Posted on 18/07/2012 by Daniel We may have been the last folk to see the Aurora in Antarctica, but when it came, it was unforgettable.

Astronomie - MESSENGER arrive aux abords de Mercure - AstroSurf Envoyé 03-01-2008 19:42 j'ai relevé ces precisions sur le site, où il s'avère que c'est bien pour diminuer la vitesse de la sonde afin qu'elle soit capturée par Mercure...Mais ça ne répond pas tout à fait à la question : pourquoi peut-on envoyer directement une sonde en orbite de Mars et pas de Mercure ? Rôle joué par le Soleil, faible masse de Mercure ?? "5. Why take such a long and complex route to Mercury? Although it is not that difficult to fly a spacecraft by Mercury, the task of placing a spacecraft into orbit around the planet is a significant challenge.

La Silla La Silla, in the southern part of the Atacama desert, 600 km north of Santiago de Chile and at an altitude of 2400 metres is the home of ESO's original observing site. Here ESO operates two major telescopes: the 3.6m telescope, and the New Technology Telescope (NTT). They are equipped with state of the art instruments either built completely by ESO or by external consortia, with substantial contribution by ESO. La Silla Observatory is hosting regularly Visitor Instruments that are attached to a telescope, for the duration of a run of observation and then is removed from the telescope. La Silla also hosts national telescopes, such as the 2.2-m Max-Planck telescope, 1.2-m Swiss Telescope and the 1.5-m Danish Telescope.

See Which Health Supplements Aren't Backed By Science There are a lot of fad diets and articles out there that tell you which commonplace and obscure supplements you should be adding to your diet. But how do you discern the genuine from the bullsh*t? This graph by David McCandless, which he posted to visual.ly in 2012, ranks hundreds of health supplements based on the amount of scientific research backing their big claims.

To the Moon Explore the Moon Join the Apollo astronauts on the surface in this series of stunning 360-degree panoramas (QTVRs), one each from the six successful Apollo moon landings. Lunar Puzzlers (Hot Science) If you're standing on the moon and the Earth is directly overhead, how long will it take for our planet to reach the moon's horizon? Take a shot at this and other lunar brainteasers. Last Man on the Moon Gene Cernan, who left man's final footprint on the moon in 1972, describes what it was like to lift off from the launchpad, walk in space, spend three days exploring the lunar surface, and reenter the Earth's atmosphere. Hear the Space Pioneers Buzz Aldrin on that first-ever landing.

About the Digital Universe At the center of the 1 billion light-year grid is the Milky Way and our Sun. Surrounding us are the multi-hued Tully galaxies and the blue sheets of the Sloan Digital Sky Survey that stretch out billions of light-years away. Since 1998, the American Museum of Natural History and the Hayden Planetarium have engaged in the three-dimensional mapping of the Universe. This cosmic cartography brings a new perspective to our place in the Universe and redefines our sense of home. From the Solar System out to the edge of the observable universe, the Digital Universe obtains data from scientists and organizations around the world and builds a consistent atlas where disparate data are in context with one another. The Digital Universe is distributed via free download and to planetariums around the world through our partnerships with several planetarium technology companies.
