Upcoming space events: The Jupiter Near-polar Orbiter (Arrival July 4)

National Aeronautics and Space Administration

The Jupiter Near-polar Orbiter is a NASA New Frontiers mission currently en route to the planet Jupiter. Juno was launched from Cape Canaveral Air Force Station on August 5, 2011 and will arrive on July 4, 2016. Juno will be inserted into a polar orbit around the giant planet on or around July 4, 2016. From this orbit the spacecraft will study Jupiter’s atmosphere and magnetic field. Juno will remain in orbit until October 2017, when the spacecraft will be de-orbited to crash into Jupiter.

The spacecraft's name comes from Greco-Roman mythology. The god Jupiter drew a veil of clouds around himself to hide his mischief, but his wife, the goddess Juno, was able to peer through the clouds and see Jupiter's true nature.

A Third of Milky Way Stars have Changed Orbit

Researchers have created a new map of the Milky Way which shows that nearly a third of the stars have dramatically changed their orbits.

The discovery, by a team of scientists with the Sloan Digital Sky Survey (SDSS), brings a new understanding of how stars are formed, and how they travel throughout our galaxy.

“In our modern world, many people move far away from their birthplaces, sometimes halfway around the world,” said Michael Hayden, New Mexico State University (NMSU) astronomy graduate student and lead author of the new study.
