Still others are attempting to measure the polarization of light emitted by Tabbys star, which can help determine whether the dimming is caused by something in the interstellar medium. So far, Ellis says, it appears the stars spectra has reddened, meaning bluer wavelengths of light are being absorbed more than redder ones. We were really hoping to pin down the color dependence of the dimming which we did, the dipping is reddened and wed like to then figure out which elements are the main suspects, he said. As was predicted by Tabbys paper, this might be a periodic event with a period of 7. This event happening now is supporting that ideaht Popular Science. Okay guys so this one may actually be somewhat useful. I found my old PSP and decided Id put some emulators on it, SNES, Game Boy, etc. One of the things you need.
