Outer space, or just space, is the void that exists between celestial bodies, including the Earth. It is not completely empty, but consists of a hard vacuum containing a low density of particles, predominantly a plasma of hydrogen and helium as well as electromagnetic radiation, magnetic fields, neutrinos, dust and cosmic rays. The baseline temperature, as set by the background radiation from the Big Bang, is 2.7 kelvins (K) (−270.45 °C; −454.81 °F). Plasma with a number density of less than one hydrogen atom per cubic metre and a temperature of millions of kelvins in the space between galaxies accounts for most of the baryonic (ordinary) matter in outer space; local concentrations have condensed into stars and galaxies. In most galaxies, observations provide evidence that 90% of the mass is in an unknown form, called dark matter, which interacts with other matter through gravitational but not electromagnetic forces. Data indicates that the majority of the mass-energy in the observable universe is a poorly understood vacuum energy of space which astronomers label dark energy. Intergalactic space takes up most of the volume of the Universe, but even galaxies and star systems consist almost entirely of empty space.

Tyson ponders over how long will it take for humans to visit new galaxies.
More space news and info at: http://www.coconutsciencelab.com - the NASA CIBER sounding rocket experiment has found that the black void between galaxies is actually emitting infrared light. It is thought that galaxies collide to form larger galaxies in our universe, kicking out stars. These stars are thought to be the source of the background infrared light.

Telescopes in Australia have detected huge, super powerful radio bursts from beyond our galaxy. They lasted for only milliseconds and emitted as much power as the sun doe in 300,000 years, billions of light-years away. What are they? Nobody knows. Astronomers think the events are fairly common (whatever they are) and could be colliding neutron stars, evaporating black holes, or "an entirely new type of high-energy astrophysical event," according to Cornell astronomer James Cordes. Is the answer past our current knowledge of deep space? Cara Santa Maria returns to discuss with Kim Horcher.
