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”
The reign of Jupiter, named after the father of the Olympian gods, has been long and sweet. Aside from being the largest planet in the Solar System, it was this gas giant that demonstrated in the 17th century that planets other than Earth can support a system of moons. Between its size, powerful magnetic field, and system of 79 moons, Jupiter looked set to remain the king of the planets
But it looks like Saturn, named after the father of Jupiter in Greco-Roman mythology, might have just knocked Jupiter off that pedestal. Thanks to a team led by famed astronomer Scott S. Sheppard 20 new moons have been discovered orbiting Saturn. That brings the total number of Saturnian (or Cronian) satellites to 82, putting it ahead of Jupiter’s 79. And the best part? You can help name them!Continue reading “Astronomers Find 20 – Yes 20 – New Moons for Saturn”
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.”
In 2023, NASA plans to launch the Europa Clipper mission, a robotic explorer that will study Jupiter’s enigmatic moon Europa. The purpose of this mission is to explore Europa’s ice shell and interior to learn more about the moon’s composition, geology, and interactions between the surface and subsurface. Most of all, the purpose of this mission is to shed light on whether or not life could exist within Europa’s interior ocean.
This presents numerous challenges, many of which arise from the fact that the Europa Clipper will be very far from Earth when it conducts its science operations. To address this, a team of researchers from NASA’s Jet Propulsion Laboratory (JPL) and Arizona State University (ASU) designed a series of machine-learning algorithms that will allow the mission to explore Europa with a degree of autonom.Continue reading “AI Could Help the Europa Clipper Mission Make New Discoveries!”
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”
Jupiter opposition season is nigh, and with it, the largest planet in our solar system and its iconic Great Red Spot present us with a key mystery.
Jupiter in 2019
Jupiter reaches opposition for 2019 on June 10th. For an outer planet with an orbit exterior to the Earth, opposition simply means it’s ‘opposite’ to the Sun as seen from our Earthly vantage point. This means that Jupiter will rise in the east and dominate the sky throughout the June night, after the Sun sets in the west.Continue reading “Is Jupiter’s Great Red Spot Vanishing as We Near Opposition 2019?”
Jupiter: a massive, lifeless gas giant out there on the other side of the asteroid belt. It’s a behemoth, containing 2.5 times as much mass as all the other planets combined. To top it off, it’s named after the Roman God of War.
Earth: a tiny rocky world, almost too close to the Sun, where life rises and falls, punctuated repeatedly by extinctions. Compared to Jupiter, it’s a gum-drop world: Jupiter is 317.8 times the mass of Earth. And Earth is named after a goddess in German paganism, or so we think.

Jeff Morgenthaler, a senior scientist at the Planetary Science Institute, likes to think of himself as an experimental physicist whose laboratory opens to the sky. He has used a comet to measure the ionization lifetime of carbon, is using Io’s atmosphere as a probe of conditions in Jupiter’s magnetosphere and has constructed a small-aperture coronagraph to monitor measure Jupiter’s magnetospheric response to a large volcanic eruption on Io.
