A Supermassive Black Hole's Strong Magnetic Fields Revealed in a New Light

The Event Horizon Telescope (EHT) collaboration has published new results that describe for the first time how light from the edge of the supermassive black hole M87* spirals as it escapes the black hole’s intense gravity, a signature known as circular polarization. The way light’s electric field prefers to rotate clockwise or counterclockwise as it travels carries information about the magnetic field and types of high-energy particles around the black hole. 

What is ALMA Astronomy News?

The Atacama Large Millimeter/submillimeter Array (ALMA) -the largest astronomical project in existence- is a single telescope of revolutionary design, composed of 66 high precision antennas located in northern Chile. ALMA is an international partnership of ESO (Europe), NSF (U.S) and NINS (Japan) together with NRC (Canada), MOST and ASIAA (Taiwan), and KASI (Republic of Korea), in cooperation with the Republic of Chile We love the Cosmos!
