The 365 Days Of Astronomy, The Daily Podcast Of The International Year Of Astronomy 2009

Telescopes are, in a way, time-travel machines to the distant past & faraway galaxies. The speed of light is the Universe’s speed limit. Forget that 55 MPH thing. 186,000 miles per second is more like it! Lightspeed is also the speed of gravity and electricity, so there’s that.   For example, it takes light from the Sun over 8 minutes to reach Earth, so the sunlight we feel on our faces is, on average, actually 8 minutes 25 seconds old. When astronomers use telescopes to look at galaxies in space, they find some that are close by and some that are farther away—that is, some that are younger and some that are very much older.    We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!

From April 21, 2021. A survey of the stellar nursery in the Orion Nebula Cluster provides evidence that stars compete for material and their size depends on what they gather rather than their initial core size. Plus, NASA mission updates, fast radio bursts, neutron stars, visible novae, and mountain building in the Andes.   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!

Today’s guest:  Dr. Jamie Rankin, Voyager Deputy Project Scientist, talks with us today about all things Interstellar. She is also an Associate Research Scholar and Lecturer in Space Physics at Princeton University. NASA-JPL continues to communicate with both Voyagers 1 and 2 as they explore interstellar space. Closer to home, IBEX and three soon-to-be-launched new spacecraft study the protective bubble of our star system from the inside, while also investigating our star’s ever-changing effect on Earth.   H’ad astra historia is the official podcast for the Historical Astronomy Division of the American Astronomical Society. We’re here to share stories from and about the people who study the stars, planets, and the cosmos. We’ll be hearing from individuals who not only study the history of astronomy, but also those who lived it, who were “in the room” during pivotal events within the last 50 years or so.     Podcaster:  Loretta Cannon (an AAS affiliate via Rose City Astronomers) is a science-and-word-nerd who

https://www.youtube.com/watch?v=RXtYUawd4AY From Feb 14, 2020. Hosted by Fraser Cain. It’s hard to really wrap your mind around the vast distances between stars. The fastest spacecraft ever launched into an interstellar trajectory right now is Voyager 1. If it was directed at the nearest star, it would take tens of thousands of years to make the journey across the interstellar gulf.   Even so, groups like Breakthrough Starshot and Icarus Interstellar are working on plans right now to try and send spacecraft to other stars, ideally within our lifetimes.   But we can see how quickly technology is advancing all around us, from materials science to high energy physics, not to mention reusable rockets.   It seems reasonable to ask, should we invest in an interstellar mission now, or wait a few decades or even centuries for better technology to come along which could make the trip much shorter?   Watch Chris Hadfield's video: https://www.youtube.com/watch?v=Y6woV3encOA   Andrew Kennedy’s paper: https://www.researc

Hosted by Steve Nerlich. A. Interstellar Travel. There is so much imagined interstellar flitting about in star trek, wars etc, that it seems almost inevitable it will all really happen one day. That is, that we might set off from Earth in the morning and arrive at Alpha Centauri system in time for tea. It’s only 4.3 light years away after all. B. Space Colony. A standard theme of science fiction and science forecasting is that we’ll establish space colonies one day. This is certainly possible, if not likely, but there are a number of issues to think through. Most importantly, you need energy – so if you are going to build a real space colony that’s in space then the Earth – Moon Lagrange points 4 and 5 might be good since they keep pace with the Moon around its Earth orbit and so will get Earth-Moon levels of solar flux. Or you might float a gondola above the clouds of Venus and get even more solar flux – or you might do the traditional thing and build on the surface of a celestial body. The Moon is good for

For the briefest of moments, some dead stars can flash brighter than their entire galaxy (in Radio light) and then live to do it again and again. It’s time for an update on fast radio bursts, a phenomenon we’ve only known about for a few decades. In this time astronomers have learned a tremendous amount them. They’re not solved, but we’re getting closer!   SUPPORTED BY YOU This Episode is made possible thanks to our Patrons on Patreon.

Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org Today's 2 topics: - Comet C2/2015 V2 Johnson was discovered by my Catalina Sky Survey teammate Jess Johnson on November 3, 2015. It travels on a hyperbolic path around the Sun which is highly inclined to the plane where the planets and most of the asteroids travel. Jess's comet's path takes it from deep space into the inner solar system slightly further from the Sun than the planet Mars. Although it will not get closer to the Earth than about 75 million miles it may out gas enough material to make it visible to the naked eye. - If Lunar and Martian colonists are to have chips and salsa they will need grow their own tomatoes. To test methods to do this German Aerospace Center or DLR has developed the EU:CROPIS satellite which will be launched by a Space-X Falcon 9 rocket into low Earth orbit sometime in 2017.

Hosted by Dr. Jacinta Delhaize & Dr. Tshiamiso Makwela.   In this “unplugged” episode, we hear from our own! New host Dr. Tshiamiso Makwela tells us about her research and we introduce you to our new podcast manager, Francois Campher.   Tshiamiso (Tshia) discusses her work in the field of Astronomy Education Research. She asks us “how big is big” and “how far is far”? Tshia explains why these concepts so difficult, yet so important, to comprehend.   Tshia is a post-doc researcher at the University of Cape Town (UCT). She is part of the IAU (International Astronomy Union’s) Office for Astronomy Education (OAE). She explains to us how her work contributes to the advancement of Astronomy education in South Africa and the rest of the world.   We also hear from our brand new podcast manager, Francois Campher! Francois tells us a bit about himself and how he got co-opted into his new role. He also shares his first impressions of the very unique The Cosmic Savannah “studio” (a.k.a cupboard behind the files!)   W

From December 10, 2021. Using data provided by the Backyard Worlds: Planet 9 citizen science project, volunteers found a possible large planet or brown dwarf orbiting its star at a distance of more than 1,600 astronomical units. Plus, NASA launches the Imaging X-ray Polarimetry Explorer, and we review Ghostbusters: Afterlife.   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!
