Nimbly combining the tools of art and science, SETI Institute Artist in Residence Xin Liu expresses what it means to be human through a diverse body of work that includes frost-coated sculptures, a bubbling fountain of crude oil, and a performance in outer space.    In a new body of sculptures exhibited at Pioneer Works in New York City, the artist considers her fears around having her eggs frozen, creating warped, skeletal, frost-covered sculptures that propose a human body transformed...

Many people feel that it’s very important for humanity’s long term survival that we become a multiplanet species.  Traveling to and possibly even inhabiting other planets in our solar system is not only possible with our current levels of technology, but compared to going to the stars, it’s downright easy.   But what about traveling to exoplanets?  Can we reach the stars?   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just...

From April 10, 2024. This week’s episode is brought to you by last week’s terrible weather. While experiencing hail and thunder IRL, we also saw press release after press release and article after article discussing climate change. This one-two punch of new science and the need for a new roof means we will touch on climate change in our closer look this week. We apologize in advance; it’s not pretty out there -- unless you like storm chasing, then it’s kind of the stuff of dreams at the...

Only eight times in history have scientists found an asteroid, tracked its trajectory toward Earth, and caught the resulting fireball on cameras. The latest of these eight events happened in January 2024, with the discovery of asteroid 2024 BX1, a mere three hours before impacting the atmosphere over Europe. And of course, the SETI Institute's own Dr. Peter Jenniskens was hot on the trail, flying to Germany to help search for meteorite fragments. Within the week, several pieces were...

Well, when you’re traveling close to the speed of light, everything really is relative; especially the passage of time. This week, Fraser and Pamela give you the skinny on Einstein’s Special Theory of Relativity. After listening to a few thought experiments, you too should be able to wrap your head around this amazing theory.   We've...

Using archival data from the Gemini North telescope, a team of astronomers have measured the heaviest pair of supermassive black holes ever found. The merging of two supermassive black holes is a phenomenon that has long been predicted, though never observed. In this podcast, Dr. Roger Romani discusses the discovery of this system and what we can learn about massive black hole pairs from this system.   Bios:  - Rob Sparks is in the Communications, Education and Engagement group at NSF’s...

Throughout human history, comets have fascinated us. They have gone from signs and portents of bad things to come to well-studied and even visited "dirty snowballs". Every year, observers search the skies, hoping to discover the Next Big Comet - Halley, Hyakutake, Hale–Bopp, McNaught. From SOHO and LINEAR to ATLAS and IRAS, numerous observatories have continued to add to the count of discovered comets.  But it doesn't require expensive hardware or spacecraft to make similar observations from...

From August 8, 2023. A massive, Jupiter-sized exoplanet has been discovered orbiting a small, low-mass star and this discovery is challenging theories on how planets form around their stars. The planet, called TOI-4860 b, is about the same size as Jupiter and orbits its star once every 1.5 Earth days, classifying it as a warm Jupiter. This is unusual because planets this large are not supposed to form around low-mass stars.   We've added a new way to donate to 365 Days of Astronomy to...

This episode was recorded on March 14, 2024. Earlier in March, Congress voted into place the FY2024 budgets for multiple agencies, including NASA. The agency is being asked for an overall 2% cut. Combined with inflation rates over 3%, we are looking at a fairly significant cut to the U.S. budget for space science. Dr. Pamela Gay breaks down what these cuts will affect, including people and missions, as we move forward with this already stressful fiscal year.   We've added a new way to...
