Who owns the moon?

In this episode we talk about cosmic property rights. Who owns the moon? What about Mars? Can a company legally mine an asteroid?

In space news: ULA and SpaceX go head to head at a Senate hearing committee, how tensions with Russia can negatively impact the US space programs, COSMOS, a new space plane is being developed and the original space shuttle wooden mockup is moving.

You can watch the full Senate sub-committee video here:

A Week in Science - Global Population Growth

Our population recently hit 7 billion- that’s a lot of people! This week we look at how humans compare to other species including bacteria, ants and rodents. Plus a sobering look at how we impact wild mammal populations.

Infinite Minute №11 - The Star-Forming Region Sharpless 2-106

This is a stunning star-forming region known as Sharpless 2-106. It is located in the constellation Cygnus the Swan some 2,000 light years from Earth.

The wings of this emission nebula are bubbles of hot gas created by strong stellar winds and high energy radiation coming from a massive, hot, newborn star in the center.

The central star is very large, some 15 times more massive than our Sun. Two jets of matter streaming from its poles heat the surrounding gas and dust to ten thousand degrees Celsius.

Dust that is not ionized by the stellar jets reflect the light from the star which is ejecting material at roughly 100 km/s.

Five Second Rule Debunked!

Does anyone really think there’s something magical about five seconds when it comes to food and the floor? There’s a press release out this week (I still can’t find the study) that claims that the five second rule is “real”. It isn’t. If bacteria are going to transfer, they do it fast. Plus, there is no evidence at all that actual health is affected by the time food sits on the floor. Watch Aaron recoil at both bologna and the mangling of science in this week’s episode.

The Science of Dust

Wanna get dirty with me?

From star stuff to microscopic fluff to skin cells that slough while you’re in the buff, the universe of dust is curious enough to turn your mind into a cream puff.

May this week’s episode spread like dust on the wind.
