After five long years jour­ney­ing through the vast­ness of space, NASA’s Juno space­craft is reveal­ing details about the biggest plan­et in our solar sys­tem: Jupiter.

This comes near­ly one year after the world was wowed by the New Hori­zons mis­sion, which returned the most detailed pic­tures of Plu­to we’ve ever seen.

Jupiter, how­ev­er, is dif­fer­ent. It’s one of the bright­est objects in the night sky, and humans have been observ­ing it with the naked eye for as long as we’ve been around.

Then, some 400 years ago, a man named Galileo Galilei peered through his tele­scope, and not­ed some lit­tle stars mov­ing around Jupiter in an inter­est­ing way.

He con­clud­ed that these were satel­lites, or moons, and that they must be orbit­ing the plan­et. Along with his oth­er body of work, this obser­va­tion led to our mod­ern under­stand­ing of the solar sys­tem, and how celes­tial objects move around each other.

And, for the first time ever, this orbital motion has been cap­tured on video by Juno:

Despite being based on record­ed obser­va­tion, Galileo’s views went against the con­ven­tion­al think­ing of his time, and he was tried for heresy and placed under house arrest by the Catholic Church until his death (the church issued an offi­cial apol­o­gy in 1992).

The field of astron­o­my has grown in leaps since then, and yet we still know sur­pris­ing­ly lit­tle about Jupiter and what it’s made of.

Juno seeks to reveal some of those details.

Now in orbit around the gas giant, Juno will help us under­stand the planet’s com­po­si­tion, its mag­net­ic field, its grav­i­ty field, how the plan­et was formed, how much water might be present, and what’s under­neath all those lay­ers of gas. Does it have a sur­face? This is one of the great­est intrigues about this famil­iar fix­ture of our night sky.

And stick­ing with tra­di­tion­al astro­nom­i­cal nam­ing con­ven­tions, Juno was per­fect for the job. As NASA states: The god Jupiter drew a veil of clouds around him­self to hide his mis­chief, and his wife, the god­dess Juno, was able to peer through the clouds and reveal Jupiter’s true nature.”

Keep an eye out for more imagery from the Juno mis­sion over the com­ing months.
