Jupiter

It's tough to be the biggest planet in the solar system, and this fall Jupiter is taking a beating.

On Oct. 15, skywatchers in Japan observed a flash in the atmosphere of the planet's northern hemisphere likely caused by an asteroid slamming into Jupiter, just over a month after a skywatcher in Brazil made a similar observation.

"The flash felt like it was shining for a very long time to me," Twitter user @yotsuyubi21, who photographed the flash with a Celestron C6 telescope, told Space.com.

They confirmed the observation with a team led by Ko Arimatsu, an astronomer at Japan's Kyoto University who takes part in the Organized Autotelescopes for Serendipitous Event Survey (OASES) project.

According to a tweet posted by the project, that observation included two different types of light, visible and infrared, giving Jupiter an eerie pink glow.

Jupiter regularly experiences such impacts because of the powerful gravitational tug associated with its mass: Smaller objects, like the asteroids that litter the solar system, can easily end up pulled into the planet's thick, turbulent atmosphere.

Some research suggests that objects at least 150 feet (45 meters) across hit Jupiter every few months on average, although observational constraints mean that even the most thorough monitoring program might be able to catch just one impact or so per year.

According to Sky & Telescope, the Oct. 15 flash hit the planet's North Tropical Zone, near the southern edge of the North Temperate Belt.

Observers aren't yet sure whether the impact left a debris field that scientists can monitor; the September flash did not, and several factors including the object's size and the impact's location factor into observability.
