To complement the EHT findings, several NASA spacecraft were part of a large effort, coordinated by the EHT’s Multiwavelength Working Group, to observe the black hole using different wavelengths of light. The gravity is so strong because matter (the mass) has been squeezed into a tiny space. Black holes are thought to result from the collapse of very massive stars at the ends of their evolution. The EHT image relied on light in radio wavelengths and shows the black hole's shadow against the backdrop of high-energy material around it.Ī black hole is a dense, compact object whose gravitational pull is so strong that – within a certain distance of it – nothing can escape, not even light. includes the National Science Foundation. EHT is an international collaboration whose support in the U.S. The boundary in space around a black hole is called the "event horizon."Ī black hole and its shadow were captured in an image for the first time (2019) in a historic feat by an international network of radio telescopes called the Event Horizon Telescope (EHT). The gravity is so strong because their mass has been squeezed into a tiny space. Black holes are thought to result from the collapse of very massive stars. A black hole is a dense, compact object whose gravitational pull is so strong that nothing can escape, not even light.
