New measurements using radio occultation and data from NASA's Juno spacecraft show Jupiter is slightly smaller and more oblate than previously thought, with an equatorial radius of 71,488 km and a polar radius of 66,842 km, refining models of its interior and atmospheric dynamics.
Overwatch’s new character Anran is sparking controversy online, with fans arguing her facial design closely resembles existing heroes Kiriko and Juno, fueling a broader “same-face syndrome” critique of the game’s character art. The debate covers whether Anran is a new character or simply a cosmetic skin, highlights ongoing discussions about uniform aesthetics in the franchise, and notes potential cultural and stylistic pressures influencing female character designs.
Juno's latest measurements refine Jupiter's equatorial diameter to 88,841 miles (142,976 km) and polar diameter to 83,067 miles (133,684 km), about 5 miles and 15 miles smaller than earlier estimates, confirming the planet's oblateness and aiding models of its interior and atmosphere.
NASA’s Juno mission refines Jupiter’s size and shape, finding a polar radius of about 66,842 km (roughly 12 km smaller) and an equatorial radius of about 71,488 km (roughly 4 km smaller) than older measurements. By tracking how Juno’s radio signals bend through the atmosphere and accounting for winds, scientists produced more accurate dimensions, improving models of Jupiter’s interior and gas giants overall; as co-author Yohai Kaspi notes, “Textbooks will need to be updated.”
Using a high-detail computational model that combines chemistry and hydrodynamics with data from NASA's Juno and Galileo missions, researchers estimate Jupiter contains about 1.5 times the Sun's oxygen, supporting icy-material formation theories; the model also finds gas diffusion is far slower than previously thought, highlighting how much remains unknown about the giant planet's interior.
Using data from NASA's Juno and Galileo missions, researchers built a combined chemistry–hydrodynamics model of Jupiter's atmosphere. They find Jupiter may contain about 1.5 times the Sun's oxygen—far more than earlier estimates of roughly one-third—much of which is in water. The study also shows gas diffusion in Jupiter's atmosphere could be 35–40 times slower than previously thought, a result that informs theories about how the planet formed from icy material near the frost line.
NASA's Juno spacecraft captured what scientists describe as the solar system's most energetic eruption observed on Io, with multiple volcanoes lighting up simultaneously from a vast subterranean magma network. The Dec. 27, 2024 event, spotted by JIRAM during a flyby about 74,400 km above Io, released an estimated 140–260 terawatts of power and covered about 40,400 square miles (65,000 sq km). Io harbors around 400 active volcanoes driven by Jupiter's tidal forces. The synchronized eruption suggests interconnected magma reservoirs beneath Io's lava-encrusted surface, and future Io flybys will map new lava flows and ash deposits.
New 1D chemistry and 2D hydrodynamic models suggest Jupiter contains about 1.5 times more oxygen than the Sun and that its atmospheric circulation is slower than previously thought, refining theories of gas-giant formation; the work builds on NASA’s Juno data revealing complex weather and a possible fuzzy core, as the mission continues through 2025 with a planned end that preserves the moons from Earth microbes.
A 2022 Juno flyby analysis estimates Europa’s ice shell in the observed region to be about 29 kilometers (18 miles) thick on average. If a warmer, convective inner layer exists, the total thickness could be greater; the presence of dissolved salt could reduce thickness by roughly 4.8 kilometers. Near-surface “scatterers” (cracks/pores) are likely small and not major pathways for exchange with the ocean. These findings help constrain how the subsurface ocean might connect to the surface and inform upcoming Europa Clipper and Juice missions in assessing the moon’s habitability.
NASA’s Juno used its Microwave Radiometer to measure Europa’s near-surface ice shell during a 2022 flyby, finding an average thickness of about 29 km (18 miles) in the observed region and favoring thicker-shell models; if a salty layer exists, thickness could be reduced by about 3 miles. The data also reveal small near-surface scatterers—cracks and pores—not likely to provide major nutrient pathways to the subsurface ocean, with implications for future Europa Clipper and Juice missions.
China's Jiangmen Underground Neutrino Observatory (JUNO), after 17 years of development, has begun operations and achieved unprecedented precision in detecting neutrinos, potentially solving key questions about their mass hierarchy and advancing our understanding of fundamental physics.
NASA's Juno spacecraft, which has been studying Jupiter and its moons since 2016, may have been powered down due to the U.S. government shutdown, and its future remains uncertain as NASA has not confirmed whether it is still operational after its mission extension ended in September 2025.
The Jiangmen Underground Neutrino Observatory (JUNO) in China has started collecting data to study neutrinos, elusive particles that pass through matter almost undetected, aiming to understand their properties, types, and role in the universe over the next decade.
The Jiangmen Underground Neutrino Observatory (Juno) in China, a massive underground sphere filled with liquid and equipped with sensitive detectors, is set to study elusive neutrinos and their oscillations, aiming to better understand their mass hierarchy and contribute to fundamental physics research.
The finale of Butterfly leaves several characters' fates uncertain, with potential for Season 2 to explore new locations and deeper character development, especially focusing on trust, family dynamics, and the characters' future paths.
