A few hours ago NASA’s OSIRIS-REx blasted off atop an Atlas 5 411 rocket from Cape Canaveral. After nearly 55 minutes it successfully separated from the rocket’s Centaur last stage, after a few more minutes it deployed its solar panels and started communicating with the mission control center. At that point it started its journey to the asteroid 101955 Bennu to collect a sample and take it back to Earth.

NASA published the first results of the Jupiter flyby the Juno space probe performed on August 27, 2016. In about six hours, Juno reached a distance of 4.200 kilometers (2,500 miles) from the planet and above all passed above both north and south poles. The result is a series of images of the aurora at infrareds with many detail never seen before.

According to an astronomer estimate the Milky Way alone could host one billion gas giant planets like Jupiter. Twenty years of exoplanet discoveries and studies taught us that there are different types of Jovians and their study is important to understand the evolution of a solar system, including our own, given the influence of a planet of that mass. On the other hand, the study of Jupiter also helps our general understand of that class of exoplanets.
