5 Mysterious Photos Taken By NASA On The Moon!
Our curiosity has led us to investigate, every aspect and every corner of the moon.
But sometimes, when you’re looking for something, you can find unpleasant surprises, which may disturb you for a long time.
Black, Hot Ice May Be Nature’s Most Common Form of Water
The findings, published today in Nature, confirm the existence of “superionic ice,” a new phase of water with bizarre properties. Unlike the familiar ice found in your freezer or at the north pole, superionic ice is black and hot. A cube of it would weigh four times as much as a normal one. It was first theoretically predicted more than 30 years ago, and although it has never been seen until now, scientists think it might be among the most abundant forms of water in the universe.
A new experiment confirms the existence of “superionic ice,” a bizarre form of water that might comprise the bulk of giant icy planets throughout the universe.

The Milky Way at 38,000ft
This image was taken over the Atlantic Ocean somewhere between Greenland and Iceland. It points towards the galactic centre of our Milky Way. The brightest object to the top right is Jupiter. Other objects that can be seen include The Dark Horse, Pipe Nebula, M23 Cluster, M8 Lagoon Nebula, M20 Trifid Nebula, M22 Globular Cluster, M6 Butterfly Cluster, M7 Cluster among others. How many can you find?

Twisting whirlpools of electrons
In Jules Verne’s famous classic 20,000 Leagues Under the Sea, the iconic submarine Nautilus disappears into the Moskenstraumen, a massive whirlpool off the coast of Norway. In space, stars spiral around black holes; on Earth, swirling cyclones, tornadoes and dust devils rip across the land.
All these phenomena have a vortex shape, which is commonly found in nature, from galaxies to milk stirred into coffee. In the subatomic world, a stream of elementary particles or energy will spiral around a fixed axis like the tip of a corkscrew. When particles move like this, they form what we call “vortex beams.” These beams imply that the particle has a well-defined orbital angular momentum, which describes the rotation of a particle around a fixed point.
Thus, vortex beams can give us new ways of interacting with matter, e.g. enhanced sensitivity to magnetic fields in sensors, or generating new absorption channels for the interaction between radiation and tissue in medical treatments (e.g. radiotherapy). But vortex beams also enable new channels in basic interactions among elementary particles, promising new insights into the inner structure of particles such as neutrons, protons or ions.
