Scientists have developed the world's fastest atomic level quantum simulator with particles interacting with each other at speeds under one billionths of a second!

"Kenji Ohmori (Institute for Molecular Science, National Institutes of Natural Sciences, Japan) and a group of collaborators have developed the world's fastest simulator for the quantum mechanical dynamics of a large number of particles interacting with each other within one billionths of a second.

The dynamics of interactions between large numbers of electrons govern a variety of important physical and chemical phenomena, including superconductivity, magnetism and chemical reactions. An ensemble of many particles thus interacting with each other is referred to as a "strongly correlated system." Understanding the properties of strongly correlated systems is thus one of the central goals of modern sciences. It is extremely difficult, however, to predict theoretically the properties of a strongly correlated system even using the Japanese post-K supercomputer, which is planned for completion by the year 2020."

This is amazing no matter how many km you are apart .... you still feel so close 😍

Why NASA's Juno Jupiter orbiter is a big deal
NASA has shot humans to the moon, sent robots to Mars, and even sent a probe beyond the borders of our solar system. All these have been herculean efforts.

Neptune and Triton: A Montage
This computer generated montage shows Neptune as it would appear from a spacecraft approaching Triton, Neptune's largest moon at 2706 km (1683 mi) in diameter. The wind and sublimation eroded south polar cap of Triton is shown at the bottom of the Triton image, a cryovolcanic terrain at the upper right, and the enigmatic "cantaloupe terrain" at the upper left. Triton's surface is mostly covered by nitrogen frost mixed with traces of condensed methane, carbon dioxide, and carbon monoxide. The tenuous atmosphere of Triton, though only about one hundredth of one percent of Earth's atmospheric density at the surface, is thick enough to produce wind-deposited streaks of dark and bright materials of unknown composition in the south polar cap region. The southern polar cap was sublimating at the time of the Voyager 2 flyby, as indicated by the irregular and eroded appearance of the edge of the cap.

The Veil Nebula Up-close
The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus. It constitutes the visible portions of the Cygnus Loop (radio source W78, or Sharpless 103), a large but relatively faint supernova remnant. The source supernova exploded some 5,000 to 8,000 years ago, and the remnants have since expanded to cover an area roughly 3 degrees in diameter (about 6 times the diameter, or 36 times the area, of the full moon). The distance to the nebula is not precisely known, but Far Ultraviolet Spectroscopic Explorer (FUSE) data supports a distance of about 1,470 light-years.
