Yes, the Universe is expanding at an accelerating rate, sort of

Before the big explosion: The artist’s impression shows a binary star system where mass is transferred from a companion to a white dwarf. As soon as sufficient matter has collected on the surface of the dwarf star, this can trigger a nuclear explosion which in turn ignites the catastrophic nuclear burning and destroys the white dwarf – a type Ia supernova flares up.

Why the multiverse may be the most dangerous idea in physics

“Spooky” quantum entanglement reveals invisible objects

In the new experiment, the physicists entangled photons in two separate laser beams with different wavelengths, and hence color: one yellow and one red.
“This is a long-standing, really neat experimental idea,” says Paul Lett, of the National Institute of Standards and Technology in GaithersburgLett, “Now we have to see whether or not it will lead to something practical, or will remain just a clever demonstration of quantum mechanics.”(CreditBarreto-Lemos, Vergano)

Quark quartet fuels quantum feud

MOLECULAR MODEL In the molecular model, quark-antiquark pairs form two color-neutral mesons that become weakly linked as a molecule.
DIQUARK MODEL In the diquark model, the particles form quark-quark and antiquark-antiquark pairs, which are forced to combine to balance their color charges.

What lit up the universe?

A computer model shows one scenario for how light is spread through the early universe on vast scales (more than 50 million light years across). Astronomers will soon know whether or not these kinds of computer models give an accurate portrayal of light in the real cosmos. (Credit: Andrew Pontzen/Fabio Governato)

Best view yet of merging galaxies in distant Universe

In this picture, which combines views from Hubble and the Keck-II telescope on Hawaii (using adaptive optics), you can see a foreground galaxy that is acting as the gravitational lens. The galaxy resembles how our home galaxy, the Milky Way, would appear if seen edge-on. But around this galaxy there is an almost complete ring — the smeared out image of a star-forming galaxy merger far beyond. (Credit: NASA, ESA)

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)
