Jupiter Impact Update

A follow-up observation with an infrared telescope on Mauna Kea confirms that the dark mark(s) discovered near Jupiter's south pole by Australian amateur astronomer Anthony Wesley were caused by an impact of a comet or asteroid. The "hole" in Jupiter's upper atmosphere is now Earth-size or larger.
