New Observatory Takes Highest-Energy Particle Research to New Heights

As cosmic-ray particles are accelerated by a black hole in this artist's interpretation, they stream toward Earth as very-high-energy gamma-rays. Upon hitting the atmosphere, they produce a shower of particles that rain down on Earth. Most of these particles run out of energy before they hit sea level.

Swiftly Moving Gas Streamer Eclipses Supermassive Black Hole

This is an illustration of the physical, spatial and temporal picture for the outflows emanating from the vicinity of the super massive black hole in the galaxy NGC 5548. The behavior of the emission source in five epochs is shown along the time axis. The obscurer is situated at roughly 0.03 light years (0.01 parsecs) from the emission source and is only seen in 2011 and 2013 (it is much stronger in 2013). Outflow component 1 shows the most dramatic changes in its absorption troughs. Different observed ionic species are represented as colored zones within the absorbers.

Starwatch: A sister for the Sun?

These clues have been used by a team of astronomers led by the University of Texas to identify the Sun’s potential sibling. Still unnamed but known as HD 162826 or by a number of other catalog designations, it is plainly visible through binoculars high in our summer night sky.

NASA Scientists Recreate Complex Chemistry of Titan’s Atmosphere

This image is a composite of several images taken during two separate Titan flybys in 2006. The large circular feature near the center of Titan’s disk may be the remnant of a very old impact basin. The mountain ranges to the southeast of the circular feature, and the long dark, linear feature to the northwest of the old impact scar may have resulted from tectonic activity on Titan caused by the energy released when the impact occurred.

Quarks in six-packs: Exotic Particle Confirmed

For a long time, physicists were only able to reliably verify two different classes of hadrons: baryons and mesons. Experiments performed at Jülich’s accelerator COSY have now shown that, in fact, another class of exotic particles made up of six quarks exists.
