The 365 Days of Astronomy

The first in a series of three Astronomy 101 videos from this spring’s AstroCamp where Dr. Jen is explaining some basics of astronomy.   In this first video, we're taking a look at the colour of stars and why stars appear the colours they do. She'll also explain how the mass of a star is related to its temperature, what happens to expanding dying stars and why we don't see any green or purple stars.   But please do help us out by subscribing to the show:   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just...

- If we want a lunar orbiting space station, couldn’t we just send the ISS there?  Well we could, but whether it would work is another question. There’s a fundamental principle that things are built-for-purpose. Of course, you can re-purpose things, but that’s only worthwhile if it makes practical and economic sense. - Could bacteria have hopped aboard the Venera probes and seeded Venus’ atmosphere?  So, as you may have heard there’s phosphine in them there clouds of Venus and the astronomical community is cautiously excited, but also ready for a gentle let down if it turns...

The 365 Days of Astronomy

From December 7, 2009. Let’s assume that humans survive the next few hundred years without destroying ourselves, or the planet, and we actually become a space faring civilization. What kinds of challenges will we face, and what projects will we build to expand ourselves out into the Solar System and eventually the galaxy.
