From August 23, 2023. Astronomers estimate that there are more free roaming planets in our galaxy than there are planets in orbit around stars. In fact, rogue exoplanets - planets with no star whatsoever - far outnumber all other planets in our galaxy, by 20 times. Trillions of worlds wandering alone.   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: and donate as much as you can!

I don’t want to alarm the listeners but there is a flurry of particles from the Sun passing through each and every one of you right now. A lot of particles. In fact, there are 50 billion solar neutrinos passing through every one of us every second. Don’t worry,...

The 365 Days of Astronomy

From July 7, 2008. And now we reach the third part of our trilogy on the human exploration and colonization of Mars. Humans will inevitably tire of living underground, and will want to stretch their legs, and fill their lungs with fresh air. One day, we’ll contemplate the possibility of reshaping Mars to suit human life. Is it even possible? What technologies would be used, and what’s the best we can hope for?   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: and donate as much as you can!

Today's 2 topics:

- Asteroid hunters were able to discover a small Earth approaching asteroid after 57 nights of continuous rain and clouds.

- Although small space rocks pose no threat to humans, they are an interesting part of our environment, offer a chance for asteroid hunters to develop their tracking skills, and occasionally provide an opportunity for a meteorite hunter to touch an object from outer space.
