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!
Today we talk about our own home world: Earth. You might think you know the planet beneath your feet, but it’s actually one of the most interesting and dynamic places in the Solar System.
The Solar System is a really big place, and it takes forever to travel from world to world with traditional chemical rockets. But one technique, developed back in the 1960s might provide a way to dramatically shorten our travel times: nuclear rockets.
Although you can’t see the extremely faint geocorona, you can observe other components of the Earth’s nightly airglow.
No, you can’t really “dig to China.” But what if you could ride the so-called gravity train through the center of the Earth to the opposite side? How long would it take?
