Newest FRB Could Be A Rosetta Stone
Recently, this unusual-looking instrument, located in the forested hills of southern British Columbia and known as the Canadian Hydrogen Intensity Mapping Experiment, added to its list of accomplishments by finding yet another Fast Radio Burst (FRB) source. Many dozen FRBs have been uncovered since the first was found in 2007. But despite this imposing collection, we still don’t know what these strange objects are. Clearly, something taking place in the far depths of the cosmos is burping radio waves into space. The fact that FRBs for which we know the distance are far away – millions or billions of light-years – indicates that whatever they are, they’re pretty rare. Could they be the result of colliding black holes, or neutron star smashups? These were attractive ideas when FRBs were first found because of the large amounts of energy such cosmic head-ons would release. Sadly, they became less appealing once astronomers found FRB’s that burp more than once. Black holes and neutron stars are reluctant to back up and slam into one another again.
Day to Day Operations of the InVADER Instrument - InVADER Mission
Evan Eshelman goes over the day to day operations of the InVADER instrument. The InVADER mission will study underwater hydrothermal systems at Axial Seamount, the largest and most active volcano on western boundary of the Juan de Fuca tectonic plate off the coast of Oregon. The vents at the Axial Seamount generate chemical energy which can sustain life, and are high-fidelity analogues to putative vent systems on Ocean Worlds.

TESS Finds a Planet in the Habitable Zone
Senior Astronomer Seth Shostak discusses a new discovery by NASA's Transiting Exoplanet Survey Satellite.
Are We About to Find Life on Mars?
Over the past six months, numerous articles have reported weird anomalies in the atmosphere of Mars, from an outburst of methane in June 2019 to patterns in oxygen concentrations that cannot be explained by any known atmospheric or surface processes on the Red Planet. Perhaps more intriguing is the Viking Lander (Viking LR) experiment. In 1976, each of the two Viking landers performed experiments on Martian soil samples. The samples tested positive for metabolism, and researchers recently claimed that like on Earth, this is a sign for the presence of a Martian life. Finally, an Ohio scientist claims to have found photographic proof of "insect and reptile-like" life on Mars. This controversial result has been discussed at length in the media, even though most scientists rejected it. What does this mean? Are we on the verge of announcing the most profound story since humans first wondered about the existence of life elsewhere? Or are these coincidences that can be explained by geological processes, failed experiments or pareidolia? We invited two SETI Institute scientists who are experts on Mars to discuss these exciting and out of this world results. Biologist Kathryn Bywaters who has studied life in some of the most extreme environments on Earth and planetary scientist Pascal Lee who focuses on water on Mars and human exploration of the Red Planet. Both scientists will tell us if indeed we are about to discover life on Mars and the consequences of this significant discovery.

Technosignatures vs. Biosignatures: Which Will Succeed First?
Thirty-five years ago, a group of entrepreneurs and scientists founded the SETI Institute – the first scientific institute dedicated to the search for extraterrestrial life in the universe. We’re excited to commemorate this anniversary. We invited SETI Institute co-founder Jill Tarter and 2018 Drake Award Recipient Vikki Meadows to discuss the challenges and possible future strategies for the detection of life. Initiated by Jill Tarter in 1990s, Project Phoenix marked the first systematic search for technosignatures. Today, the Allen Telescope Array and Laser SETI are driving our technosignature search. The discovery that exoplanets are common has radically changed our view of the universe. The likelihood that there are habitable worlds elsewhere in the universe seems more plausible than ever before. Astronomers, including Vikki Meadows, are developing new instruments to help search for life on other planets. By analyzing data from exoplanets and identifying biosignatures, we will be able to search for habitable planets and the presence of life. Which approach will discover the first evidence of extraterrestrial life? Will technosignatures or biosignatures confirm our hypothesis that life exists outside our watery, shimmering planet and that, indeed, we are not alone? Molly Bentley, the co-host and producer of the radio program and podcast, Big Picture Science, will be the moderator.

Intelligence: Mundane or a Miracle
How do you define intelligence? Intelligence is a fuzzy concept defined by scientists as “a level of cognitive complexity.” For centuries, humanity thought that we were the most advanced, and hence, a unique expression of intelligence on Earth. We believed a series of improbable events that cannot be repeated elsewhere triggered our human intelligence, making us the only intelligent species in the Universe. Modern studies based on scientific data have shown that other types of intelligence exist in our biosphere. An intelligent organism can be a single cell that reacts to its environment. More complex brains allow species like chimpanzees or dolphins to possess sophisticated cognitive capacities and use tools, do math, and comprehend symbolic communication. Even bees can count and learn from others. So, if we are not alone in sharing the trait of intelligence, why are we not studying this wide range of intelligence in SETI and astrobiology? We invited two scientists to discuss the concept of intelligence and whether or not intelligence is a natural property of biological organisms. Lori Marino is a neuroscientist and expert in animal behavior and intelligence. She believes that the biological origin and evolution of intelligence should be integral to astrobiology. Laurance Doyle is a principal investigator with the SETI Institute who has developed an information theory for animal communications. Doyle will bring his mathematical thoughts on communication and intelligence and how we can measure the complexity of communication for a species and maybe, one day, an extraterrestrial message.

Battling Bacteria, Stopping the Superbugs - Big Picture Science
We can’t say we weren’t warned. More than 75 years ago, bacteriologist Rene Dubos cautioned that misuse of antibiotics could breed drug-resistant bacteria – and he has been proved prescient. In this episode: the rise of superbugs, why we ignored the warnings about them, how some are enlisting an old therapy to fight back, and whether we’ll heed history’s lessons in the face of a future pandemic. Plus, a weird unforeseen effect of antibiotics being investigated at the Body Farm.
Nobel Prize: Blessing or Curse?
Scientists can spend their entire career on a single idea or elaborate experiment and never find anything new. But if they make a significant breakthrough and discover what they have been looking for, they can win the ultimate prize: the Nobel Prize. Is the Nobel Prize, and any other high-profile recognition, a valid indicator of being an excellent scientist? In their ambition to pursue the Nobel gold, are scientists deceived by galactic mirages? Does the Nobel Prize hamper scientific progress by encouraging speed and competition while punishing inclusivity, collaboration, and innovation? To discuss these provocative ideas, we invited two astronomers whose life and career have been closely connected with the Nobel Prize. Brian Keating, Distinguished Professor of Physics at the University of California, San Diego, was a member of the BICEP2, a cosmology telescope that was thought to have witnessed the Big Bang in 2014. In his book, “Losing the Nobel Prize,” Brian tells the inside story of the BICEP2's detection and the ensuing scientific drama. Alex Filippenko, Professor of Astronomy at the University of California, Berkeley, was the only person to have been a member of both teams that revealed the accelerating expansion of the Universe. This groundbreaking discovery led to the 2011 Nobel Prize in Physics for the teams’ leaders.
Headed For Trouble: The Fate of Civilizations - Big Picture Science

For Good Measure, the New Kilogram - Big Picture Science
The reign of Le Grand K has come to an end. After 130 years, this hunk of metal sitting in a Parisian vault will no longer define the kilogram. The new kilogram mass will be defined by Planck’s constant, joining three other units for redefinition by fundamental constants. But as we measure with increasing precision – from cesium atomic clocks to gravitational wave detectors able to measure spacetime distortions to 1/1000th the width of a proton – is something fundamental lost along the way? Meanwhile, the BiPiSci team accepts the banana-measurement challenge. Tune in at https://bigpicturescience.org
What are Fast Radio Bursts?
Last month, a consortium of five dozen astronomers reported the discovery of eight new bursts that may lead to an answer. The objects were found with the Canadian Hydrogen Intensity Mapping Experiment, or CHIME. This unusual-looking radio telescope, about the size of a football field, consists of four metal mesh cylinders — like skateboard half-pipes — that collect and focus incoming radio waves. CHIME is in a sparsely populated, mountainous region of British Columbia about 30 miles north of the U.S. border.

Skeptic Check: Data Bias - Big Picture Science
Produced at the SETI Institute.
Big Picture Science engages the public with modern science research through smart and humorous storytelling. This week's episode is Skeptic Check: Data Bias
Sexist snow plowing? Data that guide everything from snow removal schedules to heart research often fail to consider gender. In these cases, “reference man” stands in for “average human.” Human bias also infects artificial intelligence, with speech recognition triggered only by male voices and facial recognition that can’t see black faces. We question the assumptions baked into these numbers and algorithms. Listen to the episode at https://bigpicturescience.org

Back to the Moon (Lecture 2): For Science and Exploration
The 2nd talk in our returning to the moon series.
If you'd like to see the first lecture, it's here: https://youtu.be/0IrRHDqvmxk NASA has an ambitious plan to return astronauts to the Moon. The return includes commercial and international partners with the goal of promoting a faster and more extensive exploration of the Moon as well as destinations beyond. In a fashion similar to what has been done in commercializing low-Earth orbit, NASA proposes to lead these partnerships. The plan this time is to establish a space outpost, to learn how to live in deep space, and to explore the Moon from above. Meanwhile, as assembly of this orbital outpost takes place, astronauts would land at the lunar south pole by 2024. What are the goals of this new project? Is the lunar south pole the best place to go? What science will we be able to conduct from the surface of the moon and from lunar orbit? The new plan has received both praise and criticism. Supporters praise it as valuable, as they view it as the first true step for humans to permanently settle another world and prepare for the exploration of Mars and beyond. Opponents criticize it as too rushed, too costly, or too ill-defined.
