2. APOD: 2011 May 23 - An Unexpected Flare from the Crab Nebula
... 2011 May 23 . An Unexpected Flare from the Crab Nebula . ... As recently as one month ago, gamma-ray observations of the Crab Nebula by the Fermi Gamma Ray Space Telescope showed an unexpected increase in gamma-ray brightness, becoming about five times the nebula's usual gamma-ray brightness, and fading again in only a few days. ... The above image shows how the Crab Nebula normally appears in gamma rays, as compared to the Geminga pulsar, and how it then appeared during the recent brightening. ...

4. First X-Rays From a Comet Discovered
A team of U.S. and German astrophysicists have made the first ever detection of X-rays coming from a comet. ... Following the initial detection, the team reported repeated X-ray emissions from the comet over the next 24 hours. ... One preliminary theory is that X-ray emission from the Sun was absorbed by a cloud of gaseous water molecules surrounding the nucleus of the comet, and then were re-emitted by the molecules in a process physicists call "fluorescence." ... Comets . ...

9. Event-driven Tasks and Graphical User Interfaces
... The only event-driven pieces of software were the user interface Hermes, the display server GIDS and the GDS server. ... Event-driven tasks are fundamentally different from procedural tasks. ... Using this event handling, a collection of routines has been built, which allows the programmer to construct a graphical user interface for a task. ... These are the events associated with user input keywords and one other event which is generated when a task is resumed after it was pausing. ...

11. ASP: An Ancient Universe - Changes in Stars
An Ancient Universe: How Astronomers Know the Vast Scale of Cosmic Time . THE CHANGING UNIVERSE: EVOLUTION HAPPENS! . b) Changes in Stars . One of the great discoveries of modern science is that stars (like people) live only a measurable life-time and then die. Although the lives of the stars are enormously longer than the span of a human life, we can learn about the life story of the stars by studying them at many different stages in their life cycle, from birth to death. ...

12. Influence of Climate Variables on Tree-Ring Widths of Different Species
... In order to disentangle the effects of different climate variables on tree-ring growth rates of different species, and to explore the possibility that more than one species could improve the accuracy of the reconstructions of climate using tree rings, a methodical study of trees in close proximity to the Armagh Observatory climate station was initiated together with Ana Maria Garc?a Su?rez, and continued as part of the latter's PhD thesis with John Butler and Professor Mike Baillie (QUB). ...

I loaded my config file, but when i went to apply it, the data had changed' . ... I got a 'the correlator has failed to start' error from a WAPP - what is that? ... It happens occasionally that one or several WAPPs suddenly report a large number of serious chip count errors for a second or two, and then continue taking data without any problem. ... The problem does not require any special action (like a restart of the WAPPs) since the same WAPP will work perfectly immediately afterwards. ...

One could then define the unit of current, as the current which, when flowing in a straight wire, attracts a similar current in a parallel wire 1 meter away with a force of unit strength, for every meter of the wires' length. ... Faraday also showed that a magnetic field which varied in time--like the one produced by an alternating current (AC)--could drive electric currents, if (say) copper wires were placed in it in the appropriate way. ...
