– Could a terrorist or some other nutcase take over the ISS?

On the whole, terrorists aren't all that bright - though to be fair, that is mostly due to lack of formal education rather than raw brain power.

– OK maybe you can’t physically take over the ISS but what about a cyberattack?

So firstly, I have no expertise in cyber-anything, so feel free to hit the off switch now. If you are still with us, then yes a cyberattack on the ISS is totally possible.

Host: Fraser Cain ( @fcain )
Special Guest: This week we are pleased to welcome Dr. Natalie Cabrol, Director of the Carl Sagan Center for Research at the SETI Institute (SI), to the show.

In addition to heading the strategic vision for science and exploration at the SI, Nathalie leads research projects in planetary science and astrobiology, develops science exploration strategies for Mars, Titan, and the Outer Solar System icy moons, and designs robotic field experiments. She explores high altitude lakes in the Andes where environmental conditions are analogous to early Mars. With her team, she documents life’s adaptation to extreme environments, the effect of rapid climate change on lake ecosystems and habitats, its geobiological signatures, and relevance to planetary exploration, and explores questions relating to the origins and nature of life.

By Chris Beckett & Shane Ludtke, two amateur astronomers in Saskatchewan.

The guys talk about the often overlooked beauty of our nearest cosmic neighbor, the Moon. They discuss unaided, naked eye observing, sketching, the best times to observe, the different areas on the Moon and what sorts of things you can actually see with a telescope or binoculars. They also discuss their favorite sights on the Moon and good books and charts to buy.

Paul Hill, Ralph Wilkins and Jenifer Millard host. Damien Phillips and John Wildridge produce.

As the exciting news of phosphine in the atmosphere of Venus turns into a point of contention in the astronomy world, we caught up with the study’s lead scientist Professor Jane Greaves for the inside track. In this interview we discuss:

• Getting time on a range of professional telescopes time for a risky hypothesis.
• How life could survive in the extreme environment of Venus’ highly acidic atmosphere.
• Floating graphite balloons in Venus’ atmosphere.
• Scientific challenges to this discovery being helpful rather than unwanted.
• Blinding NASA pilots in the name of science.

Today's 2 topics:

- I discovered a 200’ diameter asteroid & a friend asked what it would be like to witness the impact of such an object.

- I discovered a 200 foot diameter asteroid, 2014 SC324. In the case of 2014 SC324 its brightness comes about from the fact that as it passes the Earth opposite to the Sun it appears like a little full moon in the sky.

This week on The Cosmic Savannah Podcast we are joined by South African Astronomer, Dr. Tana Joseph who is currently based at the University of Manchester, UK. Tana holds a Royal Society Newton International Fellowship and researches things called X-ray binaries.

X-ray binaries are a type of binary star system that emit X-rays. The X-rays are produced by matter falling from a star onto an exotic object such as a neutron star or black hole.

Tana also runs AstroComms, a Science, Technology, Engineering and Mathematics (STEM) consulting and communications company. AstroComms assists STEM practitioners, institutions and policymakers to effectively leverage STEM as a driver for economic and social development.

Host: Dr. Pamela Gay ( https://cosmoquest.org/x/ & @starstryder )
Special Guest: This week we are excited (and honored) to welcome Dr. Jill Tarter to the Weekly Space Hangout. Best known for her work in the field of SETI, tonight Jill will be discussing the search for technosignatures.

Dr. Tarter is the Emeritus Chair for SETI Research at the SETI Institute in Mountain View, California and serves as a member of the Board of Trustees for that institution.

Dr. Tarter received her Bachelor of Engineering Physics Degree with Distinction from Cornell University and her Master’s Degree and a Ph.D. in Astronomy from the University of California, Berkeley. She has spent the majority of her professional career attempting to answer the old human question “Are we alone?” by searching for evidence of technological civilizations beyond Earth.

She served as Project Scientist for NASA’s SETI program, the High Resolution Microwave Survey and has conducted numerous observational programs at radio observatories worldwide. She is a Fellow of the AAAS, the California Academy of Sciences, and the Explorers Club, she was named one of the Time 100 Most Influential People in the World in 2004, and one of the Time 25 in Space in 2012, received a TED prize in 2009, two public service awards from NASA, multiple awards for communicating science to the public, and has been honored as a woman in technology. She was the 2014 Jansky Lecturer, and received a Genius Award from Liberty Science Center in 2015. She served as President of the California Academy of Sciences 2015-16. Asteroid 74824 Tarter (1999 TJ16) has been named in her honor.

Since the termination of funding for NASA’s SETI program in 1993, she has served in a leadership role to design and build the Allen Telescope Array and to secure private funding to continue the exploratory science of SETI.

Many people are now familiar with her work as portrayed by Jodie Foster in the movie Contact. Her biography Making Contact was written by Sarah Scoles and published in 2017.

You can read an excerpt from Jill's biography Making Contact and learn how to get your own copy here: https://books.google.com/books/about/...

You can learn more about Jill by visiting her SETI profile here: https://www.seti.org/our-scientists/j...
