"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.
Teaching For Better Humans 2.0 More than test scores or good gradeswhat do kids need for the future? This hour, TED speakers explore how to help children grow into better humans, both during and after this time of crisis. Guests include educators Richard Culatta and Liz Kleinrock, psychologist Thomas Curran, and writer Jacqueline Woodson.
#556 The Power of Friendship It's 2020 and times are tough. Maybe some of us are learning about social distancing the hard way. Maybe we just are all a little anxious. No matter what, we could probably use a friend. But what is a friend, exactly? And why do we need them so much? This week host Bethany Brookshire speaks with Lydia Denworth, author of the new book "Friendship: The Evolution, Biology, and Extraordinary Power of Life's Fundamental Bond".
This episode is hosted by Bethany Brookshire, science writer from Science News.
Space One of the most consistent questions we get at the show is from parents who want to know which episodes are kid-friendly and which aren't. So today, we're releasing a separate feed, Radiolab for Kids. To kick it off, we're rerunning an all-time favorite episode: Space.
In the 60's, space exploration was an American obsession. This hour, we chart the path from romance to increasing cynicism.
We begin with Ann Druyan, widow of Carl Sagan, with a story about the Voyager expedition, true love, and a golden record that travels through space. And astrophysicist Neil de Grasse Tyson explains the Coepernican Principle, and just how insignificant we are.
