Description
Objects in the Universe that brighten rapidly grab our attention. One of the most spectacular examples is Kepler's supernova. In 1604 this star was bright enough to be seen with the naked eye in the daytime for over three weeks. Another occurred in 1843 when a comet became almost as bright as the limb of the Sun. Over the centuries there have been many suddenly appearing objects in both the day and night sky. Possibly as the result of this history, most of the surveys which look for time variable objects in the sky are set to trigger on increases in brightness. On the other hand perhaps solar systems in formation dim instead of brighten. Stay tuned.
