"The size and shape of the shadow matches the precise predictions of Einstein's general theory of relativity, increasing our confidence in this century-old theory. Imaging a black hole is just the beginning of our effort to develop new tools that will enable us to interpret the massively complex data that nature gives us."
Colin Lonsdale, Director of MIT Haystack Observatory "What really made this realistic as a science goal was technology provided by the computing world, which finally caught up, and overtook, costly custom-built instrumentation. Haystack adapted newly available high-capacity hard disk drives and fast, flexible processor chips, and designed them into systems that could be used for VLBI. Once that key transition had occurred, successive generations of the systems could readily take advantage of industry-driven performance increases over time, and after more than a decade, the prodigious recording and processing speeds demanded by the EHT and black hole imaging were made a reality."
Tony Beasley, director of NSF's National Radio Astronomy Observatory "Through its leadership in ALMA and long-term support for the EHT, NRAO has once again helped to advance our understanding of the cosmos and the fundamental laws physics. This observation clearly illustrates the value of radio astronomy to scientific advancement. The next generation of radio telescopes, including the Next Generation VLA, will yield many more groundbreaking results."
Eyeballing a black hole's mass There are no scales for weighing black holes. Yet astrophysicists from the Moscow Institute of Physics and Technology have devised a new way for indirectly measuring the mass of a black hole, while also confirming its existence.
Astronomers capture first image of a black hole The Event Horizon Telescope (EHT) -- a planet-scale array of eight ground-based radio telescopes forged through international collaboration -- was designed to capture images of a black hole.
Hiding black hole found Astronomers have detected a stealthy black hole from its effects on an interstellar gas cloud.
Philosophy: What exactly is a black hole? What is a black hole? In an article that has just appeared in the journal Nature Astronomy, Ludwig-Maximilians-Universitaet (LMU) in Munich philosopher Erik Curiel shows that physicists use different definitions of the concept, depending on their own particular fields of interest.
Beyond the black hole singularity Our first glimpses into the physics that exist near the center of a black hole are being made possible using 'loop quantum gravity'--a theory that uses quantum mechanics to extend gravitational physics beyond Einstein's theory of general relativity.
Risk Why do we revere risk-takers, even when their actions terrify us? Why are some better at taking risks than others? This hour, TED speakers explore the alluring, dangerous, and calculated sides of risk. Guests include professional rock climber Alex Honnold, economist Mariana Mazzucato, psychology researcher Kashfia Rahman, structural engineer and bridge designer Ian Firth, and risk intelligence expert Dylan Evans.
#541 Wayfinding These days when we want to know where we are or how to get where we want to go, most of us will pull out a smart phone with a built-in GPS and map app. Some of us old timers might still use an old school paper map from time to time. But we didn't always used to lean so heavily on maps and technology, and in some remote places of the world some people still navigate and wayfind their way without the aid of these tools... and in some cases do better without them. This week, host Rachelle Saunders...
Dolly Parton's America: Neon Moss Today on Radiolab, we're bringing you the fourth episode of Jad's special series, Dolly Parton's America. In this episode, Jad goes back up the mountain to visit Dolly's actual Tennessee mountain home, where she tells stories about her first trips out of the holler. Back on the mountaintop, standing under the rain by the Little Pigeon River, the trip triggers memories of Jad's first visit to his father's childhood home, and opens the gateway to dizzying stories of music and migration.
