In this special podcast from the National Astronomy Meeting in Llandudno, we hear how twisted sunspots cause solar flares, how 17th century poetry can put a date on a supernova, and why some pulsars are part-timers. We'll find out how CANDELS and LOFAR can probe the early universe, while DEBRIS looks for dusty disks around stars. Plus, we shed light on your solar science questions!

 Taken by Hinode's Solar Optical Telescope on Jan. 12, 2007, this image of the sun reveals the filamentary nature of the plasma connecting regions of different magnetic polarity. Hinode captures these very dynamic pictures of the chromosphere. The...

 A composite image of the Crab Nebula showing the X-ray (blue), and optical (red) images superimposed. The size of the X-ray image is smaller because the higher energy X-ray emitting electrons radiate away their energy more quickly than the lower...
