Cozy Dark emerging technology began work in 2010 as a skunkworks-style engineering firm and is registered with CCR and NSPIRES.
Our early engineering & design efforts have focused on orbital debris solutions and electrodynamic tether technology.
Zach Urbina founded Cozy Dark with the cooperation of technical, research, and academic colleagues in the Southern California AeroAstro community.
We also have a growing library of space science talks featuring Apollo astronaut Buzz Aldrin, astrophysicist Sean Carroll and more.

![Planet Population Is Plentiful: Planets Around Stars Are the Rule Rather Than the Exception |
An international team, including three astronomers from the European Southern Observatory (ESO), has used the technique of gravitational microlensing to measure how common planets are in the Milky Way. After a six-year search that surveyed millions of stars, the team concludes that planets around stars are the rule rather than the exception.
Over the past 16 years, astronomers have detected more than 700 confirmed exoplanets [1] and have started to probe the spectra (eso1002) and atmospheres (eso1047) of these worlds. While studying the properties of individual exoplanets is undeniably valuable, a much more basic question remains: how commonplace are planets in the Milky Way?
Most currently known exoplanets were found either by detecting the effect of the gravitational pull of the planet on its host star or by catching the planet as it passes in front of its star and slightly dims it. Both of these techniques are much more sensitive to planets that are either massive or close to their stars, or both, and many planets will be missed.
An international team of astronomers has searched for exoplanets using a totally different method — gravitational microlensing — that can detect planets over a wide range of mass and those that lie much further from their stars. continue reading](http://25.media.tumblr.com/tumblr_ly14hrdpA01qb7n75o1_500.jpg)
