Comet C/2019 Y4 was discovered on December 28th, appears to orbit the sun every 5,000 to 6,000 years. As it gets closer to the sun, it gets brighter and it's tail gets longer. There's a good chance it'll be visible to the naked eye, possibly the brightest object in the sky this coming May.

Fun fact, comets are also thought to be harbingers of plague.
