APOD 2.3


Hey the one person who reads this! We're covering the Comet Holmes again, which has continued to fascinate denizens of this universe with its newly gained brightness and visibility to the naked eye. When looking closer and past its blurry brightness, usually through the use of a high-resolution telescope, one can distinguish a blue tail on Holmes. Why is this so? Apparently solar wind is impacting the ions in Holmes's surrounding cloud and pushing them away from the sun, creating the tail effect. Since this is a recent development, it suggests that this increased brightness was not due to one singular happening but a continuing series of processes. We're quite lucky to have the chance to study a comet in such detail, as Halley is being a jerk and won't be seen for another few decades.
