Aurora on Jupiter

NASA's Juno probe is finally in orbit around Jupiter!
And just a few days ago, NASA posted to their Instagram feed this video of auroras over Jupiter taken by the Hubble Space Telescope. Amazing...

Bright auroras on Jupiter! This composite video illustrates the auroras on Jupiter relative to their position on the giant planet. As on Earth, auroras are produced by the interaction of a planet's magnetic field with its atmosphere. The Jupiter auroras observed by our Hubble Space Telescope are some of the most active and brightest ever caught by Hubble, reaching intensities over a thousand times brighter than those seen on Earth. Hubble's sensitivity to ultraviolet light captures the glow of the auroras above Jupiter's cloud top. Fourth of July, our solar-powered Juno spacecraft will arrive at Jupiter after an almost five-year journey. In the evening of July 4, Juno will perform a suspenseful orbit insertion maneuver. Once in Jupiter’s orbit, the spacecraft will circle the Jovian world 37 times during 20 months, skimming to within 3,100 miles (5,000 km) above the cloud tops. This is the first time a spacecraft will orbit the poles of Jupiter, providing new answers to ongoing mysteries about the planet’s core, composition and magnetic fields. Credit: NASA, ESA, J.

Air Bonsai

These magical, floating bonsai plants are made by Hoshinchu, a company based in Kyushu in northern Japan. The electrified base creates a magnetic field that supports the small moss ball or ceramic bowl in which the bonsai grows.


They are available through a Kickstarter campaign. Visit the Hoshinchu website or their Kickstarter page, both linked below:

It Sings

The European Space Agency (ESA) have released audio of the comet upon which us little ol' human beings just landed. And it is not what you would have expected... trilling, gurgling, bubbling...



From the ESA description:
"Rosetta’s Plasma Consortium (RPC) has uncovered a mysterious ‘song’ that Comet 67P/Churyumov-Gerasimenko is singing into space. The comet seems to be emitting a ‘song’ in the form of oscillations in the magnetic field in the comet’s environment. It is being sung at 40-50 millihertz, far below human hearing, which typically picks up sound between 20 Hz and 20 kHz. To make the music audible to the human ear, the frequencies have been increased in this recording. Original data credit: ESA/Rosetta/RPC/RPC-MAG. This sonification of the RPC-Mag data was compiled by German composer Manuel Senfft (www.tagirijus.de). Thumbnail image credit: ESA/Rosetta/NAVCAM – CC BY-SA IGO 3.0"
