A careful statistical comparison of observations recorded by NASA’s Juno mission and the Planetary Science Institute’s Io Input Output observatory (IoIO) shows that IoIO observations reliably predict the density of Jupiter’s plasma disk, an important part of Jupiter’s magnetosphere, according to a new Geophysical Research Letters paper co-authored by Planetary Science Institute Senior Scientist Jeff […]

UK astronomers are a step closer to playing a leading role in NASA’s search for alien life in the coming decades as they continue developing one of the core instruments of the Habitable Worlds Observatory (HWO). The exciting mission—the U.S. space agency’s next flagship space telescope after the Nancy Grace Roman Space Telescope—is expected to […]

Astronomers have discovered a remarkably tiny group of six young galaxies just 1.2 billion years after the Big Bang. This may be a rare glimpse of how some of the universe’s largest galaxies formed. The paper outlining the findings was submitted to the arXiv preprint server on July 13.
