Just as a literature buff might explore a novel for recurring themes, physicists and mathematicians search for repeating structures present throughout nature.

Grab a mixing bowl from your kitchen, throw in a handful of aluminum balls, apply some high voltage, and watch an elegant dance unfold where particles re-arrange themselves into a distinct "crystal" pattern.

Using the MUSE instrument on ESO's VLT , a team led by Thomas Collett from the University of Portsmouth in the UK first calculated the mass of ESO 325-G004 by measuring the movement of stars within this nearby elliptical galaxy .

A research team of multiple institutes, including the National Astronomical Observatory of Japan and University of Tokyo, released an unprecedentedly wide and sharp dark matter map based on the newly obtained imaging data by Hyper Suprime-Cam on the Subaru Telescope.

New Insight Into Dark Matter Halos

In the 1970s, scientists noticed something strange about the motion of galaxies. All the matter at the edge of spiral galaxies was rotating just as fast as material in the inner part of the galaxy.

Nearly 10 billion years ago in a galaxy known as PKS B1424-418, a dramatic explosion occurred.

On Sept. 14, waves of energy traveling for more than a billion years gently rattled space-time in the vicinity of Earth.

How small can a droplet shrink and remain a liquid?

By combining observations of the distant Universe made with ESA's Herschel and Planck space observatories, cosmologists have discovered what could be the precursors of the vast clusters of galaxies that we see today.

A team of astronomers, including Danai Antonopoulou and Anna Watts from the University of Amsterdam, has discovered that sudden speed jumps in the rotational velocity of pulsars have a minimum size, and that they are caused not by the unpinning and displacement of just one sub-surface superfluid vortex, but by billions.

First discovered in 2007, "fast radio bursts" continue to defy explanation.

The Galactic Mosh Pit

Astronomers have discovered that our Galaxy wobbles. An international team of astronomers around Mary Williams from the Leibniz Institute for Astrophysics Potsdam (AIP) detected and examined this phenomenon with the RAdial Velocity Experiment (RAVE), a survey of almost half a million stars around the Sun.

Searching for New Physics in the Universe

No one knows for sure, but it is not unlikely that the universe is constructed in a completely different way than the usual theories and models of today predict.

Scientists will need further analysis to discern whether dark matter caused any of the COUPP-60 experiment's first bubbles.

Last June, attendees at the Neutrino 2012 international conference heard about two rare events observed by the IceCube neutrino telescope. Science-trained eyes immediately classified them as something they had never seen before.

This image compresses the Vela movie sequence into a single snapshot by merging pie-slice sections from eight individual frames.

The first direct detection of radioactive titanium associated with supernova remnant 1987A has been made by ESA's Integral space observatory. The radioactive decay has likely been powering the glowing remnant around the exploded star for the last 20 years.

The Sun is nearly the roundest object ever measured. If scaled to the size of a beach ball, it would be so round that the difference between the widest and narrow diameters would be much less than the width of a human hair.

AMS Experiment Marks 1 Year in Space

CERN today marked the Alpha Magnetic Spectrometer's first year in space with a visit from the crew of the shuttle mission, STS-134, that successfully delivered AMS to the International Space Station just over a year ago.
