In today’s episode, we’re going to look at everything from how past Earth couldn’t support photosynthesis because the days were just too short, to current Earth letting us get hit by more Cosmic Rays prior to Earthquakes going off, and to supernovae threatening our world while alien stars eat other planets.
Nov 24th: Once and Future Life on Venus, Earth, and Mars
Each week, when we set off to do this show, we start with one core idea: We want to tell you what is new in space and astronomy… and remember Earth is a planet too.
Nov 17th: Earth Science is Planetary Science
In this episode, we need to take one of our periodic looks at our planet’s science and understand what it means to life as we know it. But we will only look at Earth for the first two segments
Nov 10th: A New Space Race
Space science isn’t where the money is… at least not yet. Astronomy and planetary science in the U.S. are funded by NASA, the National Science Foundation, and a variety of smaller foundations and extremely wealthy individuals.
Nov 8th: ALMA Data Helps Confirm Mechanism Behind Gas Stripping of Galaxies
A new research project called the Virgo Environment Traced in Carbon Monoxide Survey (VERTICO) used data collected by the Atacama Large Millimeter/submillimeter Array (ALMA) to understand just what is stripping star-forming gases out of the Virgo Cluster of galaxies
Nov 3rd: The History of Life As We Know It
Today’s EVSN will look at how we now work to understand the history of life on Earth by studying the geology of our planet and apply them to Mars, and exoplanets.
Oct 27th: Meteors, Meteor Showers & Their Parent Bodies
Today EVSN discuss more about meteors – including the source of the Geminids meteor shower, asteroid Phaethon – as well as hot planets, hungry black holes, and how we’re working to uncover the identity of dark matter
Oct 25th: Early Universe Star Formation Came in Bursts
Researchers looked at lensed galaxy systems, searched for nearby analogs to those distant systems, and found that in general, the systems showed signs of bingeing star formation and then quiet lulls.
Oct 20th: SETI and the Very Large Array
Today we journey out to look at the super massive black hole in the core of M87, and then Beth Johnson will join us with an interview of the SETI Institute’s Dr. Chenoa Tremblay and how radio astronomers are one step closer to simultaneously looking for life and doing science with the very large array.
Oct 19th: Another Possible Exomoon Discovered
Researchers have potentially found a Neptune-sized exomoon orbiting a Jupiter-sized planet in a system with a Sun-like star, making it the second such potential exomoon discovered to date.
