As our last podcast episode, Connor and Nik interview each other. We summarize the highlight of the observatory program and our scientific works.
Why the Dark Age?There is certainly plenty of light to go around but there is no new light being made. We won't see any new light until the stars start to form. Hence the dark ages.Where we left off, about 300,000 years after the big bang the universe is a balmy 3,500 degrees celsius. More or less the entire universe looks like the area just above the surface of the sun. At this point something subtle begins to happen. During the early stages of the universe (inflation) tiny quantum fluc...
The Beginning of the Universe:Age of the Universe: 13.8 billion yearIt is just as easy to say “the universe was 1 second old” as it is to say “the universe was 10 billion degrees celsius”It’s called the “Big Bang” for a reason, this would have been the most cataclysmic explosion ever.The earliest moment: A Planck EpochAt about a billion billion billion billionth of a second in, the three primary forces (electromagnetic, strong and weak nuclear force) of the standard model would be about to se...
Looking for Extraterrestrial life:The Arecebo message:The numbers one to ten The atomic numbers of the elements hydrogen, carbon, nitrogen, oxygen, and phosphorus, which make up deoxyribonucleic acid (DNA) The formulas for the chemical compounds that make up the nucleotides of DNA The estimated number of DNA nucleotides in the human genome, and a graphic of the double helix structure of DNA The dimension (physical height) of an average man, a graphic figure of a human bein...
We interview Mike Smith, a PhD student, at University of Hertfordshire, in the United Kingdom.Hertfordshire in the UKHe has also spent time in Kingston at Queen’s University, working with our group.He is also associated with the Alan Turing Institute in the UK as well.Links to Science Outreach Material:McDonald InstituteRoyal Astronomical SocietyAstronomy on TapSpecial thanks to Colin Vendromin for the music, also thanks to Zac Kenny for the logo!
Introduction:Plan today is to try and solve the paradox from Living Universe E1. If life should be everywhere and we don’t see it, then what happened?The Fermi paradox: Why don't we see life everywhere?Simple Solutions:The “Rare Earth” solution just means that in some way, Earth-like planets are very rare. Maybe there is some mechanism that stops rocky planets from forming in the habitable zone.The “Rare Chemistry” solution means that maybe Earth got lucky in having just the right mix of chem...
We interview Dr. Charles Joseph Woodford, a knowledge translation specialist at Arthur B. McDonald Institute at Queen’s University.Recently moved to Kingston to work at Queen’s University with the McDonald Institute.From Newfoundland; Bachelor in Physics and Applied Mathematics. With also a minor in Russian studies from Memorial University of NewfoundlandPhD. in Theoretical and Numerical Astrophysics from University of Toronto.Binary Black holes:Black holes are essentially dead stars. There c...
Introduction:What is life?Life is considered a characteristic of something that preserves, furthers or reinforces its existence in the given environment This characteristic exhibits all or most of the following traits: Homeostasis, Organization, Metabolism, Growth, Adaptation, Response to Stimuli, Reproduction.It is important as well to specify what kind of life we are looking for. One may search for intelligent life by looking for radio signals, but bacteria may just change the chemistry of ...
We interview Dr. Nathan Deg, a Software developer for the Canadian Institute for Radio Astronomy:Resides at Queen’s University and comes from Nova Scotia but was born in Kingstonfocuses on numerical simulations of isolated and interacting pairs of galaxiesAchieved a bachelor’s from Saint Mary’s University and AstrophysicsAnd then a Masters and PhD in simulations of galaxies here at Queen’sLeft Canada for a little while and worked in University of Cape Town in South AfricaParts of the Milky Wa...
Introduction:Last episode in the “Dangerous Universe” series, Cosmic Calamity todayNext series Living UniverseContent Warning: this episode can get a bit depressing, if that’s not something you need in your life right now, please feel free to skip this episode.Overview:What is the Cosmos or Universe? Currently, one part matter, five parts dark matter, and 14 parts dark energyThe universe is our word for everything.When we talk about it expanding, it is expanding into itself (which is a w...
Introduction:We have Arnaud Michel, a master’s student in Astrophysics at Queen’sHe focuses on formation of planets in our galaxyHails from Fribourg, Switzerland.Completed his bachelor degree in Physics at Quest University in Sqamish, BC.Has worked as a research assistant at UVic and University of Bern in Switzerland.Leading cutting edge research using telescopes like ALMA and JCMT.Research:To study how proptoplanetary disks evolve around young stars.Focuses on the evolution and the movement ...
IntroductionWhat is a Galaxy? Mostly a ball of dark matter, but really a whole bunch moreGas, dust, stars, black holes and other dead starsAs a very rough gauge it’s dark matter, 1/10th stars, 1/100th gas, 1/1000th dustOften galaxies travel together, with one or a few big galaxies and lots of smaller ones swirling around.What does it mean to kill a galaxy?We think of galaxies as being active/alive if they are forming new stars. However the biggest galaxies grow mostly by eating other gal...
Introduction:Dr. Mark Richardson is the Educational and Outreach Officer at the Arthur B. McDonald Canadian Astroparticle Physics Research Institute.Got his start at St. Mary’s University with an honours in Astrophysics, and Masters and Ph.D. at Arizona State University.Expertise in modelling galaxy formation and evolution using cosmological simulations.A big advocate for Equity, Diversity, Inclusivity in Physics (or STEM in general)Research:To study the evolution of galaxies in the Universe,...
Overview:What is a star? Ball of hydrogenBalance of fusion and gravity (talk by Connor Stone on elements in the universe)Radiation transfer, convection, radiationFrom very small (a tenth of the mass of our sun) to very large (thousand times the mass of our sun)What methods are there to destroy a star?Most straightforward, just wait. It’ll turn into a planetary nebula, or go supernovaHave a nearby white dwarf pull off materialFall into a black holeWait for it:Small stars potentially live ...
Asteroids:Asteroids are failed planets. During the formation of our solar system, there was a lot of dust cooling down and coming together due to gravity, called protoplanets. In these objects, heavy metals sank to the center, and lighter elements (carbon & silicates) remained on the surface. Some of these objects became planets, others became asteroids. There are two kinds: rubble piles (small rocks held together with gravity) and solid metal cores.Most of the asteroids live in stab...
Introduction:Simran Nerval recently received her Masters Degree at Queen's UniversityShe is very active in science outreach as a coordinator for Let's Talk Science, GEMINI-P, and the IDEAS initiative. She has given several public talks including one for the Queen's Observatory, Astronomy on Tap, and the Sunshine Coast Astronomy ClubShe studies observational signatures of cosmic inflationCosmic inflation is a hypothesized early stage in the universe where it would have expanded very rapidly an...
Introduction:NASA Dragonfly mission is an 8-blade drone on the Saturn’s largest moon Titan. Pencilled to launch in 2027 and arrive in 2035.Dragonfly will sample and examine dozens of promising sites around Titan and search for the building blocks of life. Dragonfly’s main aim is going to be to study the building block of life. So, answer questions like “what happened in the past that made life possible on Earth?” Titan is hard to study from Earth because it has methane cloudsHowever...
Introduction:In the last episode (it has been a while, go back and listen to it), we talk about the science goals of the JWST mission.Today, we will talk about the technologies in the JWST mission.Launch:JWST is currently scheduled to be launched in Nov 2021.The James Webb Space Telescope will be launched on an Ariane 5 rocket. The launch vehicle is part of the European contribution to the mission. Webb will be launched from Arianespace's ELA-3 launch complex at European Spaceport locate...
Introduction - A telescope for the past:JWST (James Webb Space Telescope) is an orbiting infrared observatory that is a successor to HST. Using the infrared wavelength. JWST will be able to look at the start of galaxies, stars, planetary systems. In the universe, the further away you look the further back in time you are looking. JWST is designed to look at the beginning of the universe, going back 13 billion years in the past.A Successor to Hubble:Hubble: Optical and UV, JWST: Inf...
