Study explains why Jupiter's jet stream reverses course on a predictable schedule
Dec 19, 2017 (UPI)
The latest research -- published this week in the Journal of Geophysical Research-Planets -- reveals that gravity waves are the primary driver of the reversal o...
Juno probes the depths of Jupiter's Great Red Spot
Dec 13, 2017 (JPL)
"One of the most basic questions about Jupiter's Great Red Spot is: how deep are the roots?" said Scott Bolton, Juno's principal investigator from the Southwest...
Does New Horizons' Next Target Have a Moon?
Dec 13, 2017 (SPX)
That's the latest theory coming from NASA's New Horizons team, as it continues to analyze telescope data on the target of a New Year's Day 2019 flyby. "We reall...
New Horizons Corrects Its Course in the Kuiper Belt
Dec 11, 2017 (SPX)
Setting a record for the farthest spacecraft course correction to date, the engine burn also adjusted the arrival time at MU69 to optimize flyby science. Teleme...
Wrapping up 2017 one year out from MU69
Dec 07, 2017 (SPX)
As I write this, New Horizons is wrapping up an active period that began when the spacecraft emerged from hibernation mode in September. But soon, on Dec. 21, w...
Research bolsters possibility of plate tectonics on Europa
Dec 05, 2017 (SPX)
