This episode reminds you to look up, look out, and reflect on what we see around us. Stories cover a weird white dwarf that is doing things our Sun may do billions of years from now, how satellite images can now be used to measure river flows here and on Mars, and Titan, as well as the emerging field of planetary geoarcheology. And also climate change. Buckle up, the news isn’t good.
There are 18 satellite constellations, like Starlink, being planned. These constellations will contain 543,811 satellites. Today EVSN are going to look at early warning systems that are being developed, and how future – more highly mobile satellites, can both do good and create chaos.
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.
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.
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
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.
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.
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
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.
For decades now, our planetary science news cycles have been dominated by Mars. No, it’s time for Venus. Lets get to know VERITAS, the mission bound to Venus.
