On April 10, 2020, the Juno spacecraft observed a fireball on Jupiter that was consistent with the impact of a 1–4-meter (3.3–13.1 ft) meteor. It was the first fireball to be detected by Juno. Researchers estimate Jupiter experiences approximately 24,000 impact events of this size per year—around 2.7 per hour.
Phaeton (alternatively Phaethon / ˈ f eɪ. ə θ ən / or Phaëton / ˈ f eɪ. ə t ən /; from Ancient Greek: Φαέθων, romanized: Phaéthōn, pronounced [pʰa.é.tʰɔːn]) was the hypothetical planet hypothesized by the Titius–Bode law to have existed between the orbits of Mars and Jupiter, the destruction of which supposedly led to the formation of the asteroid belt (including the ...
The exploration of Jupiter has been conducted via close observations by automated spacecraft. It began with the arrival of Pioneer 10 into the Jovian system in 1973, and, as of 2023, has continued with eight further spacecraft missions in the vicinity of Jupiter. All of these missions were undertaken by the National Aeronautics and Space ...
NASA releases stunning new photos of Jupiter. Marking the latest foray into space exploration, NASA is preparing to launch its first mission to explore Jupiter's moon, Europa, to determine if it ...
Impact event. Damage to trees caused by the Tunguska event. The object, just 50–80 metres (150–240 feet) across, exploded 6–10 km (4–6 miles) above the surface, shattering windows hundreds of km away. An impact event is a collision between astronomical objects causing measurable effects. [1]
Metallic hydrogen. Metallic hydrogen is a phase of hydrogen in which it behaves like an electrical conductor. This phase was predicted in 1935 on theoretical grounds by Eugene Wigner and Hillard Bell Huntington. [1]
Jupiter is the fifth planet from the Sun and the largest in the Solar System. It is a gas giant with a mass more than 2.5 times that of all the other planets in the ...
The Jupiter Icy Moons Explorer (Juice, formerly JUICE [3]) is an interplanetary spacecraft on its way to orbit and study three icy moons of Jupiter: Ganymede, Callisto, and Europa. These planetary-mass moons are planned to be studied because they are thought to have beneath their frozen surfaces significant bodies of liquid water, which would ...
