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:

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.

Hubble’s Stunning Monkey Head Nebula

Astronomers using the Hubble Space Telescope have captured infrared-light images of a churning region of star birth 6,400 light-years away. New from Hubblecast.

The collection of images reveals a shadowy, dense knot of gas and dust sharply contrasted against a backdrop of brilliant glowing gas in the Monkey Head Nebula (also known as NGC 2174).

The image demonstrates Hubble’s powerful infrared vision and offers a tantalizing hint of what scientists can expect from the upcoming James Webb Space Telescope. Observations of NGC 2174 were taken in February, 2014.

Massive newborn stars near the center of the nebula (and toward the right in this image) are blasting away at dust within the nebula. The ultraviolet light emitted by these bright stars helps shape the dust into giant pillars.

This carving action occurs because the nebula is mostly composed of hydrogen gas, which becomes ionized by the ultraviolet radiation. As the dust particles are warmed by the ultraviolet light of the stars, they heat up and begin to glow at infrared wavelengths.

Probe To Fly Between Saturn And Its Rings

On its final orbit In 2017, NASA’s Cassini probe will fly between the inner edge of the D ring and the upper atmosphere of the gas giant. It will also fly though an Enceladus plume in the next few years.

Intergalactic Voids Are Not So Empty - ‘Tendrils’ Pierce Cosmic Bubbles

Astronomers observing with the Anglo-Australian Telescope have found a strangely arranged population of faint galaxies penetrating what were thought to be huge empty regions of space. Termed ‘tendrils’ these strings of matter may interconnect.

Can Tatooine Be Real?

We’re familiar with the sky on Tatooine with its twin suns. But could a planet actually orbit two stars at the same time? Could you have a planet in a multiple star system with 4, 6 or more suns?
