We’ve now discovered thousands of exoplanets, we’re learning more and more about the kinds of planetary systems there are out there across the Universe. But are planets like Earth unique or totally rare?
Today at #365DaysOfAstro, @cheapastro questions some questions. Do we have the ability to measure the exact amount of heat arriving at the Earth from the Sun? & If we want a lunar orbiting space station, couldn’t we just send the ISS there?
Fraser gives 5 answers to the question, “why should we explore space when we have so many problems here on Earth?”
The Earth is teeming with life, but the upper atmosphere to kilometers underground. There’s no question that our planet has life. But is our planet itself alive?
Scientists propose using changes in the distance from the Earth to the Moon and measured by lasers as a way to detect the phenomenon of gravitational waves. Plus, JWST is working, ExoMars is at risk.

Finding Earth-sized planets around other stars is a very exciting area of astronomical research. Recently a team lead by Dr. Katie Lester followed up data from the TESS satellite using the International Gemini Observatory and the WIYN 3.5 meter telescope at Kitt Peak. They found that we may be missing many Earth-sized worlds orbiting binary stars. This podcast explores how they reached this interesting conclusion and how we may go about finding these worlds in the future.
Today we have stories about the dwarf planet Ceres and asteroid 2014 YW14 discovered by Rose Matheny
Why do people believe the Earth is flat? How do we know it’s curved? Is a debate even worth it? I discuss these questions and more in today’s Ask a Spaceman!
