RADIO ASTRONOMY

Long ago in a galaxy far far away something started sending out mysterious radio signals know as Fast Radio Bursts that formed a repeating pattern. With SPACETV Writer and Host Cambrie Caldwell.

We’ve now passed the 50th anniversary of the Apollo 11 landing, and all eyes are back on the Moon. NASA is planning to return to the Moon by 2024 with its Artemis mission, the Chinese have put the Moon firmly in their plans for space exploration, and even SpaceX thinks the Moon is the perfect destination to test out the capabilities of its Starship. But what can you do with the Moon? Refuel spacecraft with resources drawn from the lunar regolith? Mine its helium 3 for your fusion reactors? Build a lunar amusement park? In fact, the far side of the Moon might make one of the best platforms we have for radio telescopes. One side of the Moon is completely blocked from Earth’s constantly increasing radio traffic, giving it the perfect view to the most sensitive radio signals in the Universe.

Unveiling the Cosmos: Key Inventions Behind the Modern Telescope Sarah Kendrew of the European Space Agency/STScI The astronomical telescope is a relatively recent invention in the ancient science of stargazing. Over the past 400 years, generation after generation of technology has transformed telescopes from passive observing tools to complex, highly automated workhorses of science. This astounding increase in sophistication has brought forth a golden age of astronomical discovery and ever-new insights into the nature of the universe and our place within it. Join Dr. Sarah Kendrew for an illustrated guide to the technological inventions that enabled this cosmic transformation. Host: Dr. Frank Summers of the Space Telescope Science Institute Recorded live on Tuesday, November 5, 2019, at the Space Telescope Science Institute in Baltimore, Maryland, U.S.A.

One of the big mysteries in astronomy is unfolding right before our eyes: fast radio bursts. And now a new Canadian radio telescope has come online, detecting many new bursts, including the second ever seen repeating. Finally, with the right tools at their disposal, astronomers are going to be able to get to bottom of this puzzling mystery.

Astronomers over the years have picked up dozens of "fast radio bursts" (FRBs) -- mysterious radio signals detected from an unknown part of the cosmos. But for only the second time, they have now found one that repeats itself, making it more likely that we might find out where they come from.

It is impossible to know when we will get our first contact and what this message will say, but we know that this discovery will have an ethical and political impact on our world. And then what will happen next? Will the detection of ET be dangerous or beneficial for humankind? Will it change everything, including our place in the universe or will we simply continue our life knowing that ‘We are not alone’? For more than four decades, astronomers have been searching for techno-signatures: signals coming from distant technological civilizations. The first SETI searches began in the 1960s by searching for extraterrestrial radio waves and have more recently expanded to include optical (visible) signals, such as powerful laser pulses. We know that, like technological progress, the search is also accelerating, evolving with the development of new antenna arrays and new networks of telescopes which will soon be capable of listening to the entire sky, everywhere, and all the time. To discuss these points, we invited four SETI researchers: Julia DeMarines, Astrobiologist and Science Communicator at the UC Berkeley SETI Research Center, Doug Vakoch, President of METI, Eliot Gillum, director of LASER SETI and Seth Shostak, Senior Astronomer at the SETI Institute.

Fast Radio Bursts, or FRBs are blasts of radio energy that hit Earth from outside the milky way galaxy, lasting only milliseconds before they disappear. Dr. Avi Loeb of Harvard University and Harvard Smithsonian Center for Astrophysics discusses the possibility that they could be leakage from highly powerful lasers pushing on light sails or other signs of advanced extraterrestrial intelligence. As well as the interstellar object known as Oumuamua and if it is a solar sail or alien probe. Avi Loeb also discusses what are the most dangerous and immediate threats to life on earth from space, asteroid collisions, solar flares including the carrington event, and black holes.

On November 16, 1974, humans sent their first message to the stars in an attempt to contact extraterrestrials. They did this using what was then the largest radio telescope in the world, located at the Arecibo Observatory in Puerto Rico. A group of scientists led by Frank Drake and Carl Sagan sent their message to the M13 star cluster. The message was written in binary code and contained information about human DNA. It also included figures of a human, the solar system and the Arecibo telescope. The idea was that if any aliens were to receive the signal and figure out how to decode it, they would know where it came from. Because M13 is 25,000 light-years away, it will take 25,000 years for any M13 aliens to hear our message — if they are even out there. The Arecibo message is only one of several messages intended for extraterrestrials. We have also included messages on several spacecraft, such as Pioneer and Voyager.
