Landers Away!

Sep 24, 2018 Five surface instruments are scheduled for Ryugu. The Hyabusa 2 spacecraft is orbiting asteroid 162173 Ryugu, where, on September 21, 2018 it released two landers. Known as MINERVA-II, they “hop” from place-to-place on the surface. Since Ryugu’s gravity field exerts a mere .00012 m/s² acceleration (80,000 times…

Saturn’s Electric Hexagon | Space News

Space News -- Saturn's Electric Hexagon

The famous hexagon at Saturn’s north pole has perplexed scientists since its discovery since the form is not seen in any other planetary atmosphere. In recent years, simple fluidic experiments on Earth have succeeded in producing a hexagonal structure, providing an explanation that planetary scientists have heretofore favored. However, recent…

Force Multiplier

Sep 21, 2018 Jupiter generates its own power. On August 5, 2011 NASA launched the Juno mission to Jupiter. It is currently analyzing Jupiter’s massive plasmasphere, along with its electromagnetic field. Jupiter radiates more energy in the infrared than it receives from the Sun, so astronomers think that it is…

Donald Scott: The Next Step — New Evidence of Birkeland Current Activity | EU2017

Don Scott (NPA19) 550X440

Since 1908 when Kristian Birkeland proposed that Earth’s “Northern and Southern Lights” (aurorae Borealis and Australis) are powered by electric currents coming from the Sun, scientists have wondered what exact shape these currents have and whether there are any other examples of these kinds of electrical currents in our universe….

Dawn’s Twilight

Sep 19, 2018 The mission is winding down. On September 27, 2007 NASA launched the Dawn spacecraft. After observing the asteroid Vesta, Dawn headed toward Ceres. Dawn encountered the largest known asteroid on March 6, 2015, where it remains in orbit. The mission officially ended in June of 2016, but was…

Black Ideas

  Sep 18, 2018 Black holes are said to “warp space”. Consensus theories state that inside of a black hole matter occupies no volume, yet retains its gravitational forces. Those forces are so great that no light can escape, so they are called “black” holes, because they are undetectable with…

X-ray Lightning

Sep 14, 2018 Galaxies are alive with lightning flashes. “Bring in the bottled lightning, a clean tumbler, and a corkscrew.” — Charles Dickens On Earth, a primary electric discharge channel is called a lighting bolt. In slow-motion, it is easy to see that each flash is a complex series of…
