In rotating galaxies, distribution of normal matter precisely determines gravitational acceleration

A new radial acceleration relation found among spiral and irregular galaxies challenges current understanding – and possibly existence – of dark matter

Out Of The Darkness – Many Worlds
http://www.manyworlds.space/index.php/2016/09/21/out-of-the-darkness/
There was darkness for more than 100 million years after the Big Bang — a cosmos without much, or at times any, light.
So how did the lights get turned on, setting the stage for all that followed? Scientists have many theories but so far only limited data.
In the coming years, that is likely to change substantially.

The TESS reaction wheels (allowing to point the spacecraft) have been installed at Orbital ATK.

This New Equation Might Finally Unite the Two Biggest Theories in Physics, Claims Physicist
http://sci-techuniverse.blogspot.com/2016/08/this-new-equation-might-finally-unite.html

One of the most stubborn problems in physics today is the fact that our two best theories to explain the Universe -
general relativity and quantum mechanics - function perfectly well on their own, but as soon as you try to combine them,
the maths just doesn’t work out. But a Stanford theoretical physicist has just come up with a new equation that suggests
the key to finally connecting the two could be found in bizarre spacetime tunnels called wormholes.

The equation is deceptively simple: ER = EPR.

It’s not made up of numerical values, but instead represents the names of some key players in theoretical physics. On
the left side of the equation, the ER stands for Einstein and Nathan Rosen, and refers to a 1935 paper they wrote together
describing wormholes, known technically as Einstein-Rosen bridges.

NASA will host a teleconference at 2 p.m. EDT Monday, Sept. 26, to present new findings from images captured
by the agency’s Hubble Space Telescope of Jupiter’s icy moon, Europa.

Nasa scientists find 'impossible' cloud on Titan—again
http://phys.org/news/2016-09-nasa-scientists-impossible-cloud-titanagain.html
The puzzling appearance of an ice cloud seemingly out of thin air has prompted NASA scientists to suggest that a different
process than previously thought—possibly similar to one seen over Earth's poles—could be forming clouds on Saturn's moon Titan.

Located in Titan's stratosphere, the cloud is made of a compound of carbon and nitrogen known as dicyanoacetylene (C4N2),
an ingredient in the chemical cocktail that colors the giant moon's hazy, brownish-orange atmosphere.

NASA extends science operations of IRIS solar observation spacecraft - SpaceFlight Insider
http://www.spaceflightinsider.com/...a-extends-science-operations-iris-solar-observation-spacecraft/
NASA has decided to extend science operations of its IRIS space observatory dedicated to studying the Sun’s lower atmosphere.
The $19.4 million extension contract awarded by the agency secures the manufacturer’s support for the mission through September
2018 and provides additional cooperation with ground observatories worldwide.

Quantum Mechanics Revisited: Physicists Propose New Structure of Time
http://futurism.com/...ly-a-crystal-physicists-upend-quantum-mechanics-and-philosophy-with-new-idea/
Physicists propose that time may not be continuous at all, but instead represent a “crystal,” a rigid structure composed of
discrete snapshots in time. They also suggest that the smallest interval of time may be much greater than formerly supposed.

Building an Unusual White-Dwarf Duo
http://aasnova.org/2016/09/19/building-an-unusual-white-dwarf-duo/

A new study has examined how the puzzling wide binary system HS 2220+2146 — which consists of two white dwarfs orbiting
each other — might have formed. This system may be an example of a new evolutionary pathway for wide white-dwarf binaries.

Next-generation space-weather model will map the danger facing power grids.
