After an almost 5-year journey, NASA’s Juno spacecraft successfully entered Jupiter’s orbit during a 35-minute engine burn. With its suite of 9 science instruments, Juno will investigate the existence of a solid planetary core, map Jupiter’s intense magnetic field, measure the amount of water and ammonia in the deep atmosphere, and observe the planet’s auroras. Confirmation of a successful orbit insertion was received from Juno tracking data monitored at JPL, CA and Lockheed Martin Juno operations center in Denver. The telemetry and tracking data were received by NASA’s Deep Space Network antennas in Goldstone, California, and Canberra, Australia.

This visual timeline shows our evolving view of Jupiter and some of the key milestones leading up to one of the most ambitious Jupiter missions yet: Juno.

This visual timeline shows our evolving view of Jupiter and some of the key milestones leading up to one of the most ambitious Jupiter missions yet: Juno. NASA television coverage of the event begins at 10:30 pm US Eastern time. The solar-powered spacecraft is equipped with a suite of instruments to learn about how Jupiter formed, and a radiation vault to protect the electronics from massive doses of radiation near the gas giant, reaching 1,000 times the lethal level for a human.

In preparation for the imminent arrival of NASA’s Juno spacecraft in July 2016, astronomers used ESO’s Very Large Telescope to obtain spectacular new infrared images of Jupiter using the VISIR instrument. They are part of a campaign to create high-resolution maps of the giant planet to inform the work to be undertaken by Juno over the following months, helping astronomers to better understand the gas giant. This false-colour image was created by selecting and combining the best images obtained from many short VISIR exposures at a wavelength of 5 micrometres. Credit: ESO/L. Fletcher

Stunning new images and the highest-resolution maps to date of Jupiter at thermal infrared wavelengths give a glowing view of Juno’s target, a week ahead of the NASA mission’s arrival at the giant planet...

Members of the International Daya Bay Collaboration, who track the production and flavor-shifting behavior of electron antineutrinos generated at a nuclear power complex in China, have obtained the most precise measurement of these subatomic particles’ energy spectrum ever recorded. The data generated from the world’s largest sample of reactor antineutrinos indicate 2 intriguing discrepancies with theoretical predictions and provide an important measurement that will shape future reactor neutrino experiments.
