41. Phil Plait's Bad Astronomy: Mad Science
... Bad Astronomy . ... Mad Science . ... Hey, it's either this or one of those really irritating PayPal donation buttons here. ... By "biggest", you could mean brightest seen here at the Earth, or possibly the most energetic one ever seen (which does not necessarily mean brightest!) ... One star that blew up in the year 1066 didn't get very bright at all, even though it was pretty close by as those things go. ... One more thing: the typical supernova is bright for a couple of months or so. ...

42. You Can Make Stellar Images Brighter - an Astronomy Net Article
You Can Make Stellar Images Brighter . Articles | ... A few months ago I wrote an article titled "You Can’t Make Them Brighter". So why am I now writing that you can make them brighter. ... The image of a focused star is actually a small disk called the Airy disk, named after the 19 th century scientist Sir George Airy. ... For a given aperture, a smaller Airy disk means that the light is focused to a smaller disk and is therefore brighter. ... www.astronomy.net . About Astronomy Net | ...
