One of the bulbs Thomas Alva Edison used to discover thermionic emission (the Edison Effect) in 1884. Edison found when he connected an ammeter between the filament and the auxiliary electrode, a current would flow, passing through the evacuated space of the bulb from filament to electrode. This current was later found to consist of electrons.

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.

This artistic representation shows the potentially habitable exoplanet Kapteyn b and the globular cluster Omega Centauri in the background. It is believed that this cluster is the remaining core of a dwarf galaxy that merged with our own Milky Way Galaxy billions of years ago bringing Kapteyn’s star along.

Light from the explosion 12 billion years ago of a massive star at the end of its life reached Earth recently. An image of its peak afterglow, circled with blue and yellow, was captured by Southern Methodist University’s ROTSE-IIIb telescope at McDonald Observatory, Fort Davis, Texas. A bright star sits alongside the afterglow from GRB 140419A. Credit: ROTSE-IIIb, SMU
