Mars, August 27, moon hoax is fake

This image sometimes circulates on Facebook, with the claim that Mars will appear as big and bright as a full moon on August 27, 2014. It’s a hoax. Don’t believe it. Mars never appears as large as a full moon in Earth’s sky. (Credit: Unknown)

How the computer of the future keeps its cool

"When you start to make electronics smaller and denser, not only are you making much more heat in the same amount of volume, but it's much harder for the heat to flow outward," says Peter Nalbach, a theoretical physicist at the University of Hamburg, Germany. (Credit: Mehau Kulyk/Getty)

Physics research removes outcome unpredictability of ultracold atomic reactions

Probability density  of an Efimov trimer state at different three-body geometries that are characterized by the polar angle -- indicated by the trimer legends.  The key feature in the probability density is that unlike ordinary molecular binding that mostly has a single geometry, the Efimov trimer covers have a broad range of geometries. The atoms in such states behave more like in a fluid drop. (Credit: Yujun Wang, Kansas State University)

Why didn’t the Universe become a black hole?

In Einstein’s general theory of relativity, gravity is nothing more than the curvature of spacetime. A massive object, such as the sun, causes a deformation of the spacetime grid, while another object such as a planet or a light beam follows the shortest path (a “geodesic”) on this grid. To an observer, this looks like a deflection of the trajectory caused by gravity. (Bottom) A collapsing star can form a black hole so dense and massive that it creates a region of infinite curvature (a “singularity”) so that—inside the event horizon—light cannot escape. Current research in gravitation is attempting to modify general relativity to account for such objects consistent with quantum theory. (Credit: Carin Cain)

New ‘mapping nearby galaxies at Apache Point observatory’ survey launched

Shown above is part of one of the most imaged parts of the night sky, the Orion Nebula. Since the angular size of Orion's Nebula is so large on the sky, only a portion is shown here. Located just below "Orion's Belt" this star-forming region is dominated by four young, massive O stars (known as the Trapezium, not pictured here). The wispy blue, green gas seen above is composed mostly of hydrogen, the main element used in forming stars.

He explained that the two types of Sigma-sub-b particles are produced in two different spin combinations, J=1/2 and J=3/2, representing a ground state and an excited state, as predicted by theory.

The spheres represent the range of motion of the atoms, rather than the atoms themselves – the spheres have been exaggerated in size by 45 times in order to ease visualisation. The atoms on the surface have larger ranges of motion than those in the middle of the cluster. (Credit: University of York)
