Hubble Finds Spiral Galaxy with Ram Pressure-Stripped Tail in Coma Cluster

Blyth et al analyzed the gamma rays emitted during the NPDGamma Experiment and found parity-violating asymmetry, which is a specific change in behavior in the force between a neutron and a proton. They measured a 30 parts per billion preference for gamma rays to be emitted antiparallel to the neutron spin when neutrons are captured by protons in liquid hydrogen. After observing that more gammas go down than up, the experiment resolved for the first time a mirror-asymmetric component or handedness of the weak force.

On Earth, the Northern and Southern lights occur when the solar wind (electrically charged particles from the Sun) follow our planet’s geomagnetic field lines to the poles and collide with the upper atmosphere. Mars lacks a global magnetic field, so instead the solar wind piles up in front of Mars in a bow shock, which blocks charged particles from reaching the bulk of the atmosphere. However, in a process first observed by NASA’s MAVEN spacecraft, some solar wind protons can slip past the bow shock by first bonding with electrons from the Martian upper atmosphere to form hydrogen atoms. Because these hydrogen atoms are electrically neutral, they can pass through the bow shock and go on to create an ultraviolet proton aurora on the dayside of Mars.

A cutaway depicts the interior of Neptune (left). In the new experiment, Kraus et al studied a plastic simulating compounds formed from methane -- a molecule with just one carbon bound to four hydrogen atoms that causes the distinct blue cast of Neptune; methane forms hydrocarbon (hydrogen and carbon) chains that respond to high pressure and temperature to form ‘diamond rain’ in the interiors of ice giants like Neptune; the authors were able to recreate similar conditions using high-powered optical lasers and watch the small diamonds form in real time with X-rays.
