Thanks to NASA’s Juno mission, we’re seeing Jupiter like never before!
Jupiter is the largest planet in our solar system—and thanks to NASA’s Juno mission, we’re seeing it like never before! Launched in 2011, Juno has been orbiting the gas giant and sending back stunning images and groundbreaking data. Star Gazers host Trace Dominguez explores what Juno has discovered so far and how this mission will be coming to an end soon.

Today, we're going to take you on# a journey all the way to our fifth and largest planet, Jupiter, and explore one of NASA's most# fascinating missions, Juno.
Not the Sabrina Carpenter song.
The Juno mission is one of NASA's# biggest space exploration projects in recent years.
It was launched in 2011 with the primary# goal of studying Jupiter.
Juno arrived at Jupiter in July of 2016 after a 5-year journey through# space.
Its mission is to understand how Jupiter formed its cloudy atmosphere, its magnetic field# and its deep interior.
Jupiter is a gas giant, so it has no surface to land on.
So Juno just orbits# the planet, diving down into the clouds to gather data about its atmosphere.
Juno is equipped with# some of the most advanced scientific instruments ever sent to space, including a magnetometer,# an infrared spectrometer, and a gravity science experiment, all designed to peer into the heart# of Jupiter.
Scientists believe studying Jupiter will give us insights into how our whole solar# system and potentially others formed billions of years ago.
And Juno has found some pretty amazing# stuff so far.
For example, Jupiter has a magnetic field just like we do on Earth.
But Jupiter's# magnetosphere is the largest and most powerful of any planet in the solar system.
Understanding it# helps scientists learn more about how the planet's core works and how it interacts with solar winds.# Juno has also captured stunning high resolution images of Jupiter's iconic Great Red Spot, which# is a massive storm that's been raging for hundreds of years.
The spot is larger than the whole# Earth, but for some reason, it's shrinking.
Juno is helping scientists guess why that may be and# how a storm the size of a planet actually works.
One of my favorite things about Juno is what we# are learning applies to more than just Jupiter.
The data it's collecting is giving us a deeper# understanding of the building blocks of planetary formation.
That could help us learn more about# exoplanets.
Those are planets that orbit other stars.
So whether you're looking up at the night# sky tonight or just contemplating the mysteries of the universe, remember that there's a spacecraft# out there flying over Jupiter, helping us unlock secrets about the very nature of our solar# system.
For now, all missions must come to an end.
And Juno's mission wraps up in late 2025.# NASA plans to end the mission by deliberately and dramatically crashing the spacecraft into Jupiter.# The crash is actually a planetary protection plan.
Some of Jupiter's moons are targets of future# missions, hunting for life in our solar system.
So, if we don't crash Juno on purpose, it could# get pulled down and crash into one of those moons, and that risks contaminating it with leftover# Earth microbes that Juno might have on board.
By flying it into Jupiter's atmosphere, it'll burn# up in a fiery end, protecting any life that might be out there.
It's a respectful conclusion# for a spacecraft that spent nearly a decade studying the gas giant.
Juno will continue to# send data right up until its final moments, giving scientists a last valuable look into# the planet's mysteries.
Even though we'll say goodbye to Juno soon, the wealth of knowledge it's# provided will continue to inspire and inform space exploration for years to come.
Well, Juno, it's# been swell.
Until next time, keep looking up!
