A New Look – and Sound – for Messier 94

NASA’s Chandra X-ray Observatory unveiled this new look at the galaxy NGC 4736, also known as Messier 94, on June 30, 2026. Messier 94 is a spiral galaxy with a bright inner ring around it, called a starburst ring, where new stars are forming, perhaps fueled by gas driven in the unique oval-shaped structure seen […]

NASA’s Juno Peers Beneath Io’s Surface

Description This map represents data captured by the Microwave Radiometer (MWR) aboard NASA’s Juno spacecraft, indicating heat rising from just beneath the surface of Jupiter’s moon Io. While infrared instruments measure the temperature of the moon’s surface, the lowest frequency microwave channels (0.6 and 1.25 gigahertz) on the MWR can penetrate between about 6 and […]

NASA’s Juno Takes Temperature of Jupiter’s Fiery Moon Io

 NASA’s Juno mission has provided the first measurements of the temperature below the surface of Jupiter’s moon Io, revealing significant heating within the shallow subsurface of the most volcanically active world in the solar system. Collected during two close flybys, the data also shows that most of Io’s surface is remarkably smooth and composed of […]

Plasmon-Enhanced Radioisotope Thermophotovoltaic (PRTPV) Power Generation for Interstellar Missions

Keunhan ParkUniversity of Utah This proposal seeks to develop a transformative energy system — the plasmon-enhanced radioisotope Thermophotovoltaic (PRTPV) generator — that significantly surpasses the performance of current radioisotope thermoelectric generators (RTGs) in both specific power and efficiency. Designed to achieve a specific power of 17 W/kg and a thermal-to-electric conversion efficiency greater than 40%, […]
