More: Breakthrough Gravitational Wave Findings Suggest Supermassive Black Holes Are Constantly Warping Spacetime But everything in between is just filler, right? Gaining a deeper insight into nature at its most colossal scale could greatly benefit subatomic and theoretical physics.Īt the same time, radio astronomers with the International Pulsar Timing Array (IPTA) and its affiliated consortia are working to detect the gravitational wave background, the ceaseless ripples of spacetime likely produced by supermassive black hole binaries throughout the cosmos.īy imaging black holes and studying their far-reaching effects, physicists will get closer to understanding how just about everything works, at least on the supermassive and subatomic scales. Chief among those goals was to better understand some of nature’s most extreme objects-namely the origins, growth, and collisions of black holes and neutron stars. Published in 2021, the survey outlined science objectives for the astronomical community through 2030. “We plan on using laser light to beam the information equivalent of the entire Library of Congress down to Earth.”Īn Event Horizon Explorer mission would be pursuant to the goals of the National Academies of Sciences, Engineering, and Medicine’s decadal survey. “Detecting the photon ring requires recording huge volumes of data on the spacecraft,” said Peter Galison, a physicist at Harvard University and the director of the university’s Black Hole Initiative. But in order to make such detections a reality, the EHE needs to be designed, with near-absolute-zero receivers and a large radio dish. Photon rings are not visible to the EHT at its current resolution, though researchers have managed to tease out magnetic field lines emanating from the telescope’s first target, the supermassive black hole M87.ĭetectable photon rings would be evidence that black holes are spinning, distorting spacetime through their rotations. The researchers’ hope is that an Event Horizon Explorer would reveal black holes’ photon rings, made by photons of light forced into an orbit around the black hole by the behemoth’s tremendous gravity. These bright regions are called accretion discs occasionally, material from the accretion discs fall into the black holes, causing outbursts of energy. The areas surrounding many black holes are conversely very bright, as the compact objects are surrounded by superheated material drawn towards the holes by their gravity. Images of black holes really depict their “shadows,” or the region of space that is lightless. The EHT unveiled the first image of that black hole, Sagittarius A*, last year you can read astronomers’ reactions to that image here. Supermassive black holes, which can be anywhere from millions to billions of times the mass of our Sun, often reside at the center of galaxies, including at the heart of our own Milky Way. “What we are trying to do now is launch a space mission that would improve the sharpness of the EHT images by a factor of 10,” said Michael Johnson, an astrophysicist at the Harvard and Smithsonian’s Center for Astrophysics, told the Harvard Gazette.Ī quick refresher: black holes are regions of space with such intense gravity that not even photons of light can escape their event horizons.
