While this isn’t totally tech related, the idea that a random guy could discover a new comet with his trusty digital camera is pretty cool. Scientists say the comet is to dim to catch with the naked eye, but a telescope or binoculars might do the job.
Remarkably, Lovejoy made the discovery not with a telescope but using an off-the-shelf digital camera! In fact, it appears to be the very first case of the discovery of a comet discovered in this manner.
