SETI Talks: Could Rogue Planets Harbor Life? - Livestream

Life elsewhere in our galaxy may come in many exotic forms, and scientists have speculated about the existence of life on alien worlds, like rogue planets. Rogue planets are planets that are not orbiting any stars.

It’s awe-inspiring that astronomers have discovered more than 4,000 confirmed exoplanets to date (and thousands of more exoplanet candidates). However, most detection techniques rely on the existence of a host star. To detect rogue planets, astronomers use gravitational microlensing, which involves watching foreground objects pass in front of distant background stars. The chances of such an event are slim, but modern astronomers observe tens of millions of stars every 15 minutes, which will increase to 100 million with the Nancy Grace Roman Space Telescope, to detect them. Based on planets that have already been found, our Milky Way could have 50 billion wandering planets, a staggering number that may imply that if life exists on those worlds, our galaxy is full of it.

If a planet is ripped from the warm environment of its star and drifts in the frigid depths of space, it could still hold on to a liquid ocean - and maybe life - beneath an icy crust. Could submarine aliens on such a planet have a chance at survival? And for how long?

We invited two astronomers to discuss the detection and characterization of rogue planets and their potential to harbor life. Dorian Abbot, an associate professor at the University of Chicago, co-authored a proposal for a habitable planet in interstellar space in 2011. And Matthew Penny, an assistant professor at Louisiana State University, leads the MISHAPS transit survey and numerous other microlensing focused programs.

Franck Marchis, a senior planetary astronomer at the SETI Institute, will host this conversation about the future of rogue planet detection and their potential to harbor life in many sorts of weird situations that we haven’t thought of before.

Fast Radio Bursts: ElectroMagnetic Pulses from Cosmologically Distant Neutron Stars with Hundred GigaTesla Magnetic Field? - Livestream

For over a decade, radio astronomers have been observing millisecond pulses of intense radio emission. They now appear to be associated with strongly magnetized neutron stars called Magnetars, where extreme quantum electrodynamic (QED) and plasma processes take place. The rapidly developing observational picture will be summarized and a plethora of theoretical models will be reported.The possibility that Fast Radio Bursts (FRBs) and pulsar radio emission are an expression of force-free electrodynamics, as originally developed by James Clerk Maxwell, will be discussed.

A Cosmic Perspective: Searching for Aliens, Finding Ourselves - Livestream

Are we alone? Humans have been asking this question throughout history. We want to know where we came from, how we fit into the cosmos, and where we are going. We want to know whether there is life beyond the Earth and whether any of it is intelligent.

Since the middle of the twentieth century we have had tools that permit us to embark on a scientific exploration to try to answer this old question. We no longer have to ask the priests and philosophers what we should believe about extraterrestrial life; we can explore and discover what’s actually out there. Our tools are getting ever better. We have discovered extremophiles in the most unexpected places on this planet and we have discovered that there really are far more planets than stars out there. We haven’t yet found life beyond Earth, but there is currently a debate about the detection of Phosphine in the clouds of Venus, and whether this might imply biology. There is a vast amount of other potentially-habitable real estate to explore beyond our solar system, and there are many plans to do just that. The 21st century will be the century in which we will find some answers, this will be your century.

As we look up and look out, we are forced to see ourselves from a cosmic perspective; a perspective that shows us as all the same, all Earthlings. This perspective is fundamental to finding a way to sustain life on Earth for the long future.

Speaker: Dr. Marc D. Rayman, Dawn Mission Chief Engineer, Jet Propulsion Laboratory

Meeting ID: 822 9506 4802
Passcode: 437224

ABOUT THE TALK:
The ambitious and exciting Dawn mission was one of NASA's most remarkable ventures into the solar system. The spacecraft completed a dramatic exploration of Vesta in 2011-2012 and conducted a spectacular mission at Ceres from 2015 until late 2018. These were among the last uncharted worlds in the inner solar system prior to Dawn. They are the two largest residents of the main asteroid belt, that vast collection of bodies between Mars and Jupiter. Ceres is so large that it is included in the category of dwarf planets, along with Pluto.

Dawn is the only spacecraft ever to orbit a dwarf planet and is the only one ever to orbit any two extraterrestrial destinations. Such a mission would have been impossible without the use of ion propulsion, a technology that had largely been in the domain of science fiction.

ABOUT OUR SPEAKER:
Dr. Marc Rayman, who was the mission director and chief engineer, will give a fascinating and entertaining presentation on the Dawn mission and its use of ion propulsion as well as its two exotic destinations. He also will share the excitement and profundity of controlling a spaceship in deep space.

Dr. Marc Rayman is a top rocket scientist at NASA's Jet Propulsion Laboratory and a popular speaker and writer. He has been captivated by astronomy and space since he was four years old and decided at the age of nine that he wanted to earn a Ph.D. in physics and work for NASA, although it was a few more years before he did.
 
He has worked on a wide variety of missions to explore the cosmos, including Dawn (the topic of his presentation on July 24) as well as NASA's first mission to acquire close-up images of the nucleus of a comet, missions to detect planets around other stars, Voyager's mission beyond the solar system, a mission to return a sample from Mars, a laser altimeter for Mars, the Spitzer infrared space telescope, the development of systems to use lasers instead of radios to communicate with interplanetary spacecraft, and more. Marc has received many honors and awards, not only for his technical work and leadership but also for his dedication to sharing the thrill of explora

Wonderfest: Rovers, Helicopters, & Ancient Martians: Why We Explore Mars - Livestream

In 2021, three nations are sending missions to the Red Planet - including NASA's Perseverance rover with the first Mars helicopter, Ingenuity. Ancient Mars was much like Earth, with rivers, lakes, and possibly the stirrings of life; but how has it changed? Using beautiful color images from the latest space probes, astronomer Andrew Fraknoiwill reveal what we know, and what we hope to discover, about the alien world next door.
