Yesterday, we posted some incredible photos from the Juno Probe’s 29th flyby of Jupiter. Juno is in a highly elliptical orbit. It buzzes the planet at an altitude of 4,200km and then sweeps out to 8.1 million. Completing this circuit every 53 days, Juno only spends 2 hours within close proximity to Jupiter reducing the probe’s exposure to harmful radiation of high energy particles accelerated by Jupiter’s magnetic field.Continue reading “See a 360 Degree Juno-Eye View of Jupiter During an Io Eclipse”
Most massive planet in the solar system – twice that of all the other planets combined. This giant world formed from the same cloud of dust and gas that became our Sun and the rest of the planets. But Jupiter was the first-born of our planetary family. As the first planet, Jupiter’s massive gravitational field likely shaped the rest of the entire solar system. Jupiter could’ve played a role in where all the planets aligned in their orbits around the Sun…or didn’t as the asteroid belt is a vast region which could’ve been occupied by another planet were it not for Jupiter’s gravity. Gas giants like Jupiter can also hurl entire planets out of their solar systems, or themselves spiral into their stars. Saturn’s formation several million years later probably spared Jupiter this fate. Jupiter may also act as a “comet catcher.” Comets and asteroids which could otherwise fall toward the inner solar system and strike the rocky worlds like Earth are captured by Jupiter’s gravitational field instead and ultimately plunge into Jupiter’s clouds. But at other times in Earth’s history, Jupiter may have had the opposite effect, hurling asteroids in our direction – typically a bad thing but may have also resulted in water-rich rocks coming to Earth that led to the blue planet we know of today.Continue reading “Here’s Jupiter from Juno’s Latest Flyby”
On July 5, 2016, NASA’s Juno spacecraft arrived around Jupiter, becoming the second mission in history to study the gas giant from orbit – the last being the Galileo spacecraft, which orbited Jupiter from 1995 to 2003. Since then, the spacecraft has gathered data on Jupiter’s atmosphere, composition, gravity field, and magnetic field in the hopes of learning more about how the planet formed and evolved.
In addition, the spacecraft has gathered some of the most breathtaking images ever taken of Jupiter and its system of moons. In fact, as the spacecraft was making another approach towards Jupiter on December 26th, 2019, it managed to capture the first infrared images of the moon Ganymede’s northern polar region. These images will inform future missions to this satellite, which could host life beneath its icy mantle.Continue reading “Juno Captures Pictures of Ganymede for the First Time”
Artist Mik Petter has created a vibrant new piece of art based on JunoCam images of Jupiter’s Great Red Spot (GRS). The piece makes use of fractals, which are recursive mathematical creations; increasingly complex patterns that are similar to each other, yet never exactly the same.Continue reading “Artwork Inspired by Jupiter’s Great Red Spot”

Though it looks like it to us, Jupiter’s clouds do no form a flat surface. Some of its clouds rise up above the surrounding cloud tops. The two bright spots in the right center of this image are much higher than the surrounding clouds.Continue reading “Clouds On Jupiter Rising Up Above the Surrounding Atmosphere”
In a death-defying maneuver for the spacecraft, NASA’s Juno has completed an unprecedented and unplanned engine burn. The purpose? To save the spacecraft’s “life,” or at least the rest of its mission to Jupiter.
Jupiter casts a deep, dark shadow. Dark enough, in fact, to effectively kill Juno if it flies through it. Rather than let the spacecraft spend 12 battery-draining hours in Jupiter’s shadow, and then attempt a risky resuscitation on the other side, NASA took another course of action: a 10.5 hour burn of Juno’s reaction thrusters that will steer it clear of Jupiter’s life-draining shadow.Continue reading “Juno is Afraid to Death of Jupiter’s Shadow. So it Fired its Thruster for Over 10 Hours to Avoid It.”
The JunoCam onboard NASA’s Juno spacecraft continues to provide we Earthbound humans with a steady stream of stunning images of Jupiter. We can’t get enough of the gas giant’s hypnotic, other-worldly beauty. This image of Io passing over Jupiter is the latest one to awaken our sense of wonder.
This image was processed by Kevin Gill, a NASA software engineer who has produced other stunning images of Jupiter.Continue reading “Yes, This is Actually the Shadow of Io Passing Across the Surface of Jupiter.”
There’s something about Jupiter that mesmerizes those who gaze at it. It’s intricate, dazzling clouds are a visual representation of the laws of nature that’s hard to turn away from. And even though the Juno spacecraft has been at Jupiter for almost three years now, and has delivered thousands of images of the gas giant’s colourful, churning clouds, we can’t seem to satisfy our appetite.Continue reading “The Latest Insanely Beautiful Image of Jupiter Captured by Juno”
Thanks to a mission extension, NASA’s Juno probe continues to orbit Jupiter, being only the second spacecraft in history to do so. Since it arrived around the gas giant on July 5th, 2016, Juno has managed to gather a great deal of information on Jupiter’s atmosphere, magnetic and gravity environment, and its interior structure.
In that time, the probe has also managed to capture some breathtaking images of Jupiter as well. But on December 21st, during the probe’s sixteenth orbit of the gas giant, the Juno probe changed things up when four of its cameras captured images of the Jovian moon Io, showcasing its polar regions and spotting what appeared to be a volcanic eruption.Continue reading “Juno Saw One of Io’s Volcanoes Erupting During its Recent Flyby”
