An Ancient Star Gave Earth A ‘Close Call,’ But How Close?
I recommend you listen closely to this video. Let me know your thoughts about it.
Scientists have found evidence that a star passed through our solar system just 70,000 years ago: the closest star flyby ever.
The Nuclear Spectroscopic Telescope Array, accidentally discovers massive Black Holes.
A powerful NASA telescope has found not one, but ten super-massive black holes. And it did so on accident! Trace explains what exactly black holes are and why the discovery is so awesome.

Today we post this video in memory of Mr Spoke.
Produced in 2007, this overview video about NASA’s Dawn mission to giant asteroid Vesta and dwarf planet Ceres was released before the spacecraft’s launch that year. The mission greatly appreciated Leonard Nimoy’s support and participation. Dawn investigated Vesta in 2011-2012, and will arrive at Ceres March 6, 2015.
The ground feels firm and solid beneath your feet. Of course, the Earth is rotating, turning once on its axis every day. Fortunately gravity keeps you firmly attached to the planet, and because of momentum, you don’t feel the movement,the same way you don’t feel the speed of a car going down the highway. But how fast does the Earth rotate, and what about everything else in the universe?
Trace has the answers for us in this video.
Get to know plasma, the most common, but probably least understood, phase of matter in the universe!
My head is still spinning after listening to this guy explain Plasma. I wish they would slow down and actually let us keep pace…still very good explanation.
