Has Jupiter been hit by a comet or asteroid again?

A black spot that appeared in the last few days in the northern arctic region of Jupiter, raised this hypothesis. The scientists are still checking if this is not an atmospheric phenomenon.

An image taken by Anthony Woolsey, a well-known Australian astrophotographer who specializes in observing the planets, showed a black spot on Jupiter, similar to those observed after the impact of the comet fragments. Shoemaker-Levi 9 which crashed into the largest planet of the solar system in 1994. The existence of the dark mark, which appeared suddenly between July 17 and 19, was confirmed by many observers from different countries.

The hypothesis is still being tested, and that on all the sites it appears with reservations. In any case, the Sky and Telescope website stated that this hypothesis has supporting evidence such as the high brightness of the spot in the infrared range due to the reflection of sunlight. This shows that the phenomenon was caused by an asteroid or comet impact. Leigh Fletcher reported on Twitter from the Infrared Observatory in Hawaii: "These are the same properties that the Shoemaker-Levy 9 debris spots had in 1994.

According to him, it does not appear to be an atmospheric phenomenon. If it is remnants from an impact, the stain will be spread horizontally by the jet stream in the coming days.
