Radio telescopes capture best-ever snapshot of black hole jets
An international team, including NASA-funded researchers, using radio telescopes located throughout the Southern Hemisphere has produced the most detailed image of particle jets erupting from a supermassive black hole in a nearby galaxy. "These jets arise as infalling matter approaches the black hole, but we don't yet know the details of how they form and maintain themselves," said Cornelia Mueller, the study's lead author and a doctoral student at the University of Erlangen-Nuremberg in Germany. The new image shows a region less than 4.2 light-years across -- less than the distance between our sun and the nearest star. Radio-emitting features as small as 15 light-days can be seen, making this the highest-resolution view of galactic jets ever made. The study will appear in the June issue of Astronomy and Astrophysics and is available online. Mueller and her team targeted Centaurus A (Cen A), a nearby galaxy with a supermassive black hole weighing 55 million times the sun's mass.
Want to be the Next Neil deGrasse Tyson? Be Yourself. | Think Tank
There are many ways to describe Neil de Grasse Tyson. Astrophysicist. Popularizer of science. TV and radio host. Tyson should not be described, however, as Carl Sagan: the Sequel. What's the Big Idea? In an interview with Big Think, Tyson says he is often asked by fans and admirers the question "What can I do to be you?" In other words, don't aim to be a version of someone else. Watch the video here: What's the Significance? Tyson says he thinks about his good fortune every day. Your task, Tyson says, is to find opportunities that allow you to express your unique talents in ways that society will value and reward.
Philosophie verständlich : Willensfreiheit : Harry G. Frankfurt
Hauptwerke 1988 The Importance of What We Care About1999 Necessity, Volition, and Love Der klassische Kompatibilismus von Thomas Hobbes und David Hume setzt Freiheit mit Handlungsfreiheit gleich und definiert Handlungsfreiheit als die Fähigkeit, tun zu können, was man tun will. Wünsche erster und zweiter Stufe Menschen haben – wie viele andere Lebewesen auch – Wünsche: Sie wünschen sich Nahrung und Kleidung, eine neues Auto oder besseres Wetter und vieles mehr. Einen Wunsch zweiter Stufe habe ich zum Beispiel, wenn ich den Wunsch (erster Stufe) verspüre zu rauchen und gleichzeitig (auf der zweiten Stufe) wünsche, diesen Wunsch nicht zu haben. Bei den Wünschen erster Stufe unterscheidet Frankfurt Wünsche, die man einfach nur hat, von solchen, die tatsächlich handlungswirksam werden. Willensfreiheit nach Frankfurt Was bedeutet es, dass der Wille einer Person frei ist? Nehmen wir als Beispiel den Drogenabhängigen David. Freiheit und Verantwortlichkeit Kurzes Resümee Einwände Literatur
OMG SPACE
OMG SPACE is the thesis project of Margot Trudell, an OCAD graduate of their graphic design program in Toronto, Canada. This website aims to illustrate the scale and the grandeur of our solar system, as well as illustrate through the use of infographics our work in the exploration of our solar system with various spacecraft. Despite all the work that scientists are putting into space exploration and research, and all that we've learned and acheived over the past half-century, the general public isn't very aware of it. I believe that this mostly due to how this information is communicated to the general public, in a very academic and scientific manner. It's hard for most people without backgrounds in these areas to really comprehend what it means when we send a probe past Jupiter for example, or how far away Eris really is, and it's simply difficult to truly grasp the magnitude of our solar system and all it's celestial inhabitants.
13 Must-See Stargazing Eventsof 2013 | Skywatching Guide
As 2012 comes to a close, some might wonder what is looming sky-wise for 2013.What celestial events might we look forward to seeing? I’ve selected what I consider the top 13"skylights" (get it?) for the coming year, and have listed them in chronological order. The next year also promises two potentially bright comets: PANSTARRS and ISON. In general, 2013 promises an action-packed 12 months for stargazers. Jan. 21: Very Close Moon/Jupiter Conjunction For North Americans, this is a real head-turner, one easily visible even from brightly lit cities. These two bright luminaries will make their closest approach high in the evening sky for all to see.

Cybersleuths Uncover 5-Year Spy Operation Targeting Governments, Others | Threat Level
Map showing the location and industry of victims in 69 countries hit by the spy operation. Courtesy of Kaspersky Lab An advanced and well-orchestrated computer spy operation that targeted diplomats, governments and research institutions for at least five years has been uncovered by security researchers in Russia. The highly targeted campaign, which focuses primarily on victims in Eastern Europe and Central Asia based on existing data, is still live, harvesting documents and data from computers, smartphones and removable storage devices, such as USB sticks, according to Kaspersky Lab, the Moscow-based antivirus firm that uncovered the campaign. Kaspersky has dubbed the operation “Red October.” While most of the victims documented are in Eastern Europe or Central Asia, targets have been hit in 69 countries in total, including the U.S., Australia, Ireland, Switzerland, Belgium, Brazil, Spain, South Africa, Japan and the United Arab Emirates.
Dark Energy, Dark Matter
Dark Energy, Dark Matter In the early 1990s, one thing was fairly certain about the expansion of the Universe. It might have enough energy density to stop its expansion and recollapse, it might have so little energy density that it would never stop expanding, but gravity was certain to slow the expansion as time went on. Eventually theorists came up with three sorts of explanations. What Is Dark Energy? More is unknown than is known. One explanation for dark energy is that it is a property of space. Another explanation for how space acquires energy comes from the quantum theory of matter. Another explanation for dark energy is that it is a new kind of dynamical energy fluid or field, something that fills all of space but something whose effect on the expansion of the Universe is the opposite of that of matter and normal energy. A last possibility is that Einstein's theory of gravity is not correct. What Is Dark Matter? Recent Discoveries
Andromeda Project
About PHAT The Andromeda galaxy is the closest spiral galaxy to our own Milky Way. For a hundred years, Andromeda (also known by its Messier Catalog identifier, M31) has played an important role in shaping our view of the Universe. In the early 1920's, Edwin Hubble's observations of Andromeda confirmed for the first time that galaxies lie outside of the Milky Way, and that Andromeda must contain billions of stars. Today, Andromeda is a template for understanding how spiral galaxies form and evolve. The Panchromatic Hubble Andromeda Treasury (PHAT) survey (public webpage here) opens a new window on Andromeda. The Andromeda galaxy with the PHAT coverage footprint overlaid (top). Hunting for Stellar Clusters Star clusters are collections of hundreds to millions of stars that were born at the same time from the same cloud of gas. Star clusters vary greatly in terms of mass, size, age, and local environment. Distant Galaxies Peeking Through Andromeda's Stars
