SpaceTime with Stuart Gary Series 19 Episode 48 - A Bounty Of Brown Dwarfs

Jul 22, 2016, 12:57 PM

Hi...Stuart with the Show Notes for Series 19 Episode 48.

*A bounty of Brown Dwarfs and planets discovered deep in the Orion Nebula New technology allowing astronomers to peer deeper into the heart of the Orion Nebula than ever before, has revealed a massive population of previously unseen planets and brown dwarfs. The discovery shows that the Orion Nebula may be forming proportionally far more low-mass objects than closer and less active star formation regions.

*Astronomers produce the most detailed map yet of the visible universe. Astronomers have produced the largest-ever, three-dimensional map yet of the visible universe -- showing some 1.2 million galaxies -- covering over a quarter of the sky and mapping out the structure of the universe over a volume of 650 cubic billion light-years. The new map allows scientists to make the best measurements so far of the effects of a mysterious force called dark energy on the expansion of the universe and consequently the ultimate fate of the cosmos.

*Astronomers discover how the fabled man in the moon got his right eye A new study has discovered that a huge asteroid or protoplanet which crashed into the Moon 3.8 billion years ago was responsible for giving the fabled man in the moon his right eye. The massive 250 kilometre wide space rock created the Moon’s iconic Imbrium Basin as a result of the impact. This new size estimate means the Imbrium impactor was at least two times larger and 10 times more massive than previous estimates.

*NASA’s mission to touch the Sun NASA’s first mission to “touch” the Sun has passed a critical development milestone keeping it on track for launch in July 2018. The Solar Probe Plus mission will send a spacecraft on a series of data-collecting runs through the Sun’s atmosphere.
