Recently I’ve been collecting space-themed songs (for a McTyeire Hall event called the Galaxy Gala!), and then I thought of something I’ve heard of before: sounds coming from space! Because space is a vacuum, sound waves cannot travel through it. However, many objects within the Solar System do emit radio waves, and NASA scientists have […] Continue reading → Continue reading
Juno, NASA’s space probe orbiting Jupiter, has just completed it’s fourth flyby of the jovial planet. In doing so, it sent back surprising images which revealed new features of Jupiter. Specifically, the images changed scientist’s previous perception of the planet’s interior composition and structure, as well as its weather patterns. In studying massive cyclone’s captured […] Continue reading → Continue reading
We all are familiar with the Galilean Moons; those 4 largest moons orbiting Jupiter which Galileo discovered with his telescope, and which were subsequently named after his lovers. Three of these moons (Io, Europa, Ganymede) have created auroral bursts in Jupiter’s atmosphere, but Callisto had only yielded two potential footprints … until last month! We know how … Continue reading Aurora Footprint of Jupiter’s Moons → Continue reading → Continue reading
In the quest to find habitable bodies, Jupiter’s moon Europa has been a high priority on the exploration list due to its liquid saltwater ocean underneath its ice crust. Three key ingredients for life must be present in order for biological activity to take place: liquid water, chemical ingredients, and energy sources able to enable […]Continue reading → Continue reading
All planets with an atmosphere experience weather of some kind. An atmosphere allows a planet to experience wind and various forms of precipitation. On Earth, precipitation comes in the form of liquid and frozen water. Scientists have reasons to believe that on Jupiter and Saturn instead of raining water it rains diamonds. Saturn has an atmosphere that […]Continue reading → Continue reading
Last Monday (March 27), NASA’s Juno spacecraft made a historic passage within the vicinity of the cloud tops of Jupiter’s atmosphere, marking its fifth overall flyby of the gas giant and fourth “science pass”, or experimental run. The probe marked its closest point to the planet at 08:52 GMT, coming within 2700 miles of its […]Continue reading → Continue reading
On a world where the entire surface and most of the atmosphere are composed of dense, fast-moving clouds, you can imagine that the storms are slightly worse than our regular terrestrial thunderstorm. Of course, the most famous of Jupiter’s maelstroms is the Great Red Spot, aptly named for its blue color (kidding) and impressive diameter, […]Continue reading → Continue reading
As was recently discussed in class, there are two clusters of asteroids ahead of and behind Jupiter known as the “Trojans” and the “Greeks”. The first one to be discovered was an asteroid now known as “Achilles”, a hero who fought on the Greek side of the Trojan War. The Greeks are all slightly ahead […]Continue reading → Continue reading
In 1994, one year after its discovery, the fragmented remains of Comet Shoemaker-Levy 9 crashed into Jupiter’s upper atmosphere in a sequence of 23 large impacts, each releasing the energy equivalent of 25,000 megatons of TNT, more than one million times as much energy as released by the nuclear bomb dropped on Hiroshima. Orbital analysis … Continue reading Comet Shoemaker-Levy 9 →Continue reading → Continue reading
Scientists are exploring the idea that diamonds rain down from the skies on Saturn and Jupiter. Methane exists in abundance in the atmospheres of these planets, and lighting storms turn this methane into soot (which is pure carbon). As the soot falls toward the planet’s surface, it hardens under intense pressures and forms small diamonds about… Continue reading Diamond Rain?Continue reading → Continue reading
