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.

7 March 2012 | Coronal Mass Ejection evolution
Earlier tonight, Camilla SDO showed me how to use the iSWA to make my own visualized CME evolution projections. For a devout solar science geek, this absolutely made my day. Here’s a link, if you’d like to try your own.
My visualization looks at the inner planets, Mercury, Venus, Earth, and Mars, as well as the numerous space-borne observatories and instruments, and plots their orbits against the projected distribution of yesterday’s solar flare and resulting Earth-directed coronal mass ejection. - ZU
NASA’s Solar Dynamics Observatory captured this video of swirls of darker, cooler plasma caught between competing magnetic forces over the course of 30 hours. The plasma strands rotate like tornadoes caught on magnetic field lines. It sometimes feels incredible to observe such familiar-looking fluid behavior in such unfamiliar places, but it’s just a reminder that physics works no matter where you are.
NASA’s Solar Dynamics Observatory today captured this breathtaking coronal mass ejection.
At 14:59 UT we can see solar plasma being ejected.
SDO Sees Comet Lovejoy Survive Close Encounter with Sun

The Solar Dynamics Observatory (SDO) caught this dramatic image of sunspot 1302 on September 28, 2011 with the Advanced Imaging Assembly (AIA). This sunspot has produced an x-class flare, two m-class flares and several CMEs since September 24. AIA takes images in 10 different light wavelengths. This one is shown in 171 Angstroms, typically colorized in yellow on SDO images. The thin, whispy lines are called coronal loops and they are made of hot solar material – charged particles called plasma – that collect around invisible magnetic fields looping up from the sun. The 171Angstrom wavelength is one of the best for looking at these coronal loops.

Sun Emits an X-Class Flare On 9 August 2011 |
Solar flares are giant explosions on the sun that send energy, light and high speed particles into space. These flares are often associated with solar magnetic storms known as coronal mass ejections (CMEs). The number of solar flares increases approximately every 11 years, and the sun is currently moving towards another solar maximum, likely in 2013. That means more flares will be coming, some small and some big enough to send their radiation all the way to Earth.
The biggest flares are known as “X-class flares” based on a classification system that divides solar flares according to their strength. The smallest ones are A-class (near background levels), followed by B, C, M and X. Similar to the Richter scale for earthquakes, each letter represents a 10-fold increase in energy output. So an X is ten times an M and 100 times a C. Within each letter class there is a finer scale from 1 to 9. continue reading
Around 0200 UT on 30 July 2011 a fairly powerful, but brief M9-class solar flare erupted from active region 1261. It has been the strongest flare in the last few weeks.

Spectacular prominence eruption on the sun | 7 June 2011 |
A huge prominence eruption, marked by a solar flare and release of energetic particles. It looks like a fountain of plasma that blasts out of the solar surface, spreads outward, and collapses to splat back down.
