Researchers using the Juno spacecraft suddenly noticed a bright flash above the clouds
“Jupiter is hit by a huge number of impactsin a year much larger than the Earth, so the impacts themselves are not uncommon for us, the researchers note. “However, they are so short-lived that it is rather unusual to observe them. Only larger collisions can be seen from Earth, so we're lucky to have pointed the telescope at Jupiter at the right time. Over the past decade, amateur astronomers have captured six impacts on Jupiter. "
Scientists have discovered a new exotic form of ice
Since the beginning of the study of Jupiter in 2016,Juno is used to study the morphology, brightness and spectral characteristics of the planet; the device approaches the planet's surface every 53 days. The devices of the device periodically observe short-term localized ultraviolet radiation outside the aurora zone, including a single event on April 10, 2020.
Previously, researchers observed eleven brighttransient flashes that lasted from 1 to 2 milliseconds. They have been identified as Transient Luminous Events (TLEs), a phenomenon in the upper atmosphere caused by lightning. Initially, the team believed that the new bright flash could also be a transient light phenomenon, but it lasted much longer - about 17 milliseconds.
"Flash duration and spectral shapesay that it was a collision. According to our data, the radiation came from a dark body. Its approximate temperature is 9300 degrees Celsius, it was located at an altitude of 225 km, and its mass was approximately 250-1500 kg. "
