Using data from @NASAMars' InSight lander, scientists have made the most precise measurements ever of the Red Planet’s rotation. https://go.nasa.gov/3DIsWGa
How? Giant radio antennas on Earth! 🌏📡🔴 Specifically, @NASASCaN's Deep Space Network.

Fresh from Jupiter, we have new views of its active moon Io, thanks to the #JunoMission. JunoCam even caught a glimpse of a volcanic plume! This is Prometheus, the "Old Faithful of Io." More images: https://www.missionjuno.swri.edu/junocam/processing?source=public

What's Up in August? Saturn reaches opposition, meaning it's at its biggest and brightest for the year. The "shooting stars" of the Perseid meteors are a must-see overnight on August 12-13. And August brings two full moons. https://solarsystem.nasa.gov/skywatching/home/

How do planets get their names? Aside from Earth, planets in our solar system were named after ancient gods. Today, the job of naming falls to the International Astronomical Union, the internationally recognized authority for naming celestial bodies. https://solarsystem.nasa.gov/planets/

Mercury is the closest planet to our Sun – yet ice may lurk in its shadowed polar craters. New NASA research is shedding more light on the terrain near the planet's south pole.

What a fascinating time, when we can not only explore our own solar system, but glimpse the workings of other planetary systems – across both time and space – with @NASAWebb and @NASAExoplanets

July is a great month to see the center of the Milky Way under clear, dark skies. 🌌 This long exposure image reveals green airglow and details in the Milky Way not visible to the naked eye. http://solarsystem.nasa.gov/skywatching/

Due to a postponed launch that made its asteroid targets inaccessible, NASA has decided to conclude the Janus mission. Janus was part of our SIMPLEx program of low-cost, high risk science missions ride-sharing with primary missions. https://go.nasa.gov/3OaxxHg

Today our #JunoMission completed its 52nd close pass by Jupiter! Earlier this year, it captured this view of storms and hazes on the giant planet. https://www.missionjuno.swri.edu/news/nasa-s-juno-mission-observes-high-altitude-hazes-in-jupiter

Are there earthquakes on other planets? Yes – but we don’t call them earthquakes. Instead, “moonquakes” and “marsquakes” are shaking things up in space https://go.nasa.gov/3N68hP1

Venus and the Moon setting in hazy skies over Horseshoe Springs, Utah. Mars is also visible, just to the upper left of Venus. The trio will appear even closer together in the western sky tonight. More stargazing tips: https://solarsystem.nasa.gov/skywatching/whats-up/
