Scientists from NASA's Juno mission have developed the first complete 3D radiation map of the Jupiter system, including characterizing the intensity of the high-energy particles near the orbit of the icy moon Europa, and how the radiation environment is sculpted by the smaller Jovian moons orbiting near Jupiter's rings.
The work relies on data collected by Juno's star camera Advanced Stellar Compass (ASC) designed and built by Technical University of Denmark, and Stellar Reference Unit (SRU), which was built by Leonardo, S.p.A. in Florence, Italy. The two datasets complement one another, helping Juno scientists characterize the radiation environment at different energies.

For years, scientists have modeled planets based on Earth's structure-an iron core, a silicate mantle, and surface water. This model has often been applied to exoplanets, or planets outside our solar system. However, "it is only in recent years that we have begun to realize that planets are more complex than we had thought," explains Caroline Dorn, Professor for Exoplanets at ETH Zurich.

The NASA Hubble Space Telescope has captured a detailed image of UGC 4879, a dwarf irregular galaxy also known as VV124. The high-resolution capabilities of Hubble allow astronomers to observe individual stars within the galaxy, even in its most densely populated regions. This detailed view aids in accurately determining the galaxy's distance and analyzing the composition and age of its stars.

Launched in May, ESA’s EarthCARE satellite has been making waves, with the first images from three of its scientific instruments already delivered. Now, the spotlight is firmly on the atmospheric lidar, the most advanced of the satellite’s four instruments.
This cutting-edge sensor has captured detailed 20 km-high vertical profiles of atmospheric aerosols – tiny particles and droplets from natural sources like wildfires, dust, and sea spray, and from human activities like industrial emissions or burning of wood – and clouds across various regions of the globe.
