(is this a joke?) "AMATEUR ASTRONOMER GLIMPSES AN ALIEN SOLAR": "...the star is so bright its light swamps the much fainter material around it. The disk is huge bigger than our solar system, but so far away — 600 trillion kilometers— that it appears small in telescopes, and very close to the star. What Rolf did was to get rid of all that unwanted light. He first took a bunch of pictures of β Pic, and then took a second bunch of pictures of pictures of β Pic, and then took a second bunch of pictures of another star, Alpha Pictoris, which is very similar in brightness and color. He subtracted the image of the second star, removing the glare from β Pic itself. Adjusting for brightness is easy — that’s just a bit of algebra — but color was critical. Cameras respond differently to different colors, so making sure the two stars had the same hue was very important. And it worked! ...." http://blogs.discovermagazine.com/badastronomy/2011/11/26/amateur-astronomer-glimpses-an-alien-solar-system/
