New dwarf in our Solar System — When we think of dwarf planets, the first thing that comes to mind is obviously the injustice of Pluto getting demoted to one. But the truth is, these little guys (there are six currently recognised within our solar system) deserve just as much love as their mightier planetary cousins. And a new study suggests the dwarf planet club could get another member, in the form of a very small, distant object located roughly 92 astronomical units (AU) from the Sun called Planetary body 2014 UZ224, also known as DeeDee (for ‘distant dwarf’).

Huge cold spot on Jupiter — Using the Very Large Telescope array, an international team of astronomers has discovered a previously undetected cold spot on Jupiter. Measuring 14,000km wide and 12,000km across, the mysterious spot is bigger than the Earth itself. Intriguingly, the weather anomaly is likely being generated by Jupiter’s spectacular Northern Lights.
~ And it keeps regenerating itself.
Every once in a while our Sun gives off a tremendous belch of high energy particles — Called a coronal mass ejection (CME), these episodes can vary in intensity, but they can produce bursts of electrical charge when they interact with our upper atmosphere in a geomagnetic storm. In a strange twist, new research shows that geomagnetic storms can produce the opposite effect, stripping the upper atmosphere of electrons for hundreds of kilometres. Which, if you like electronic gadgets, may be a problem.
~ Apparently, a tin-foil hat does not help.
Massive asteroid passing soon — Later this month, a huge asteroid (main picture, above) that’s about 650m in length will get close enough to Earth for our viewing pleasure. Even though it won’t do any damage, this is a damn big slice of space garbage.
~ And it looks like a huge potato.
Wringing water from the desert sky — A new spongelike device uses sunlight to suck water vapor from air, even in low humidity. The device can produce nearly 3 liters of water daily for every kilogram of water-absorbing material thanks to metal organic frameworks, or MOFs. Researchers say future versions will be even better.
~ The crucial part, to do any good, will be price and ability to deploy.
3D printed parts save Boeing money — Boeing has hired Norsk Titanium AS to print titanium parts for its 787 Dreamliner, paving the way to cost savings of $2 million to $3 million for each plane. The 3D-printed metal parts will replace pieces made with more expensive traditional manufacturing, thus making the 787 more profitable.
~ One day maybe they’ll carry printers for literally on-the-fly parts manufacture.
Glowing bacteria finds landmines — More than 100 million landmines lay hidden in the ground around the world, but glowing bacteria may help us find them, according to a new study. The approach relies on small quantities of vapor released from the common explosive TNT, then a laser to remotely detect and quantify fluorescing bacteria from 20 meters away, mapping the location of the landmines.
~ A real glow of satisfaction.
