This is the final episode of our series on sci-fi universes. And this week we will tackle "The Expanse". Now we've got fusion drives, Proto-matter, g-forces! Listen up, belta lawda! Let's look at the science of our own possible (with a side of aliens) future.

Today's 2 topics:

- Around the world those who value the natural night sky are evaluating the effects of light pollution. In addition to impairing astronomy and star gazing the past 100 years of increasing light pollution is proving to be harmful to human health and the natural world upon which we all depend. The purpose of the Dark Sky Network is monitor and...

Did you know that our Sun and its many, uh, childhood friends were all born at a place much closer to the center of our Galaxy? Over the years, our Sun and its friends have been on sort of a speedy galactic tour traveling a distance of almost 10,000 light-years from the center of the Milky Way. But traveling much farther than that on a long curved trajectory! Astronomers call this the 'mass migration' of stars. Kind of like a flock of migrating birds. 

How and when did th...

Pamela is on the road in this episode as we look at how (and why) astronomers keep finding the improbable, follow the evidence to possible sources of little red dots, study the power of big star clusters to move gas, and examine the merger history of little black holes into bigger ones.

Signal" and Dr. Richard Fienberg's May 2022 essay titled, "The First Telescope on the Moon." This Month in Astronomical History is a lead-in to next month's interview with the new Editor, Dr. Mugdha Polimera.

From July 17, 2023.

The James Webb Space Telescope Has confirmed its first exoplanet, LHS 475 b, in the southern constellation Octans, using the transit technique. The TESS satellite detected the possible presence of it and JWST's NIRSpec instrument has confirmed the observation. The planet is 99% the diameter of Earth & 91.4% of Earth's mass. So your first hope is that it's a second Earth. The orbital period is only 2 days, though, so it's assuredly tidally locked & very hot. It's unlikely to have an atmosphere either, so you can forget about finding life there.

From May 25, 2009.

Last week (May 18, 2009) we took a peek into the tiny world of quantum mechanics, and its unintuitive, but very accurate mathematical predictions. And although we all appreciate the physics lesson, you're probably wondering what this all has to do with astronomy. Well, today we bring it all home and explain how quantum mechanics has given astronomers one of the most powerful tools they have to study the nature of the cosmos.

From Jan 31, 2020.

In 2006, astronomers spotted the telltale sign of a supernova detonating in the galaxy NGC 1260, located about 240 million light-years away in the constellation of Perseus. As telescopes around the world turned their collective light-gathering power on the expanding explosion designated as SN 2006gy, they realized they were seeing something very unusual.

This clearly wasn't a regular supernova. It grew to be 100 times brighter than the typical stellar explosion and lasted much much longer.

Front and the center is the need for someone - or some company - to make it easy for folks in need of a launch to find the right ride share for their satellite, no matter how small. Enter ExoLaunch. In this episode we talk with ExoLaunch CEO Robert Sproles about what their company is accomplishing as the shipping company to the stars (or at least Earth Orbit).

Dear Cheap Astronomy – Is space really empty?

Well, the universe is filled with stars, planets and galaxies, but sure all the big gaps between those things are mostly empty. Although, let's not forget dark matter. It's likely to have a wider and denser distribution than visible matter, since we think there's four times more of it than there is of light matter - but all we can really say is 'we think' since we can't see dark matter and we don't actually know what it is...
