I'm on holiday antabuse overnight delivery Comet ISON, which was discovered a year ago, is making its first spin around the sun and will come the closest to the super-hot solar surface at 1:37 p.m. EST. It may take a few hours before astronomers know if the comet survived its brush with the sun. If it survives, and maybe even if it doesn't, people in the Northern Hemisphere will have a good chance of seeing the comet — or its remains — in the first two weeks of December just before sunrise and after sunset. It won't be visible with the naked eye on Thursday, but NASA has a fleet of telescopes trained on ISON.
