Overall, this class has greatly improved my knowledge of space and the solar system.  I learned some useful (and fun) skills such as finding the north star, and the increased perspective I now have on both the solar system and the universe will be invaluable as we explore and travel more into space.

Blog 7: Space Propulsion

Posted on April 29, 2024 by Jonas Kobza

Though designing and building a rocket is a very complex endeavor, most people have a pretty good idea of what makes them fly: Burn a whole lot of fuel to produce thrust. This method does a great job of getting a rocket up to a high speed, relative to our planet and the solar system. […] Continue reading →

Crazy Stars

Posted on March 6, 2024 by Jonas Kobza

Stars like our Sun are considered “ordinary” and quite common. They produce energy through hydrogen fusion. A weirder type of star is a white dwarf. These are stars that at one point produced energy through hydrogen fusion, but have run out of hydrogen, and do not have the mass to carry out fusion energy reactions […] Continue reading →

Blog 3: Fusion

Posted on March 5, 2024 by Jonas Kobza

We hear it all the time: Fusion is the future; it’s how the sun creates energy. But, how does it work? At its core, fusion generates energy by converting four hydrogen atoms (protons) into 1 helium atom with two neutrons (Helium-4 ). On the surface, it is hard to see how any energy is created […] Continue reading →

The expanding universe

Posted on January 23, 2024 by Jonas Kobza

Most people understand that the earth moves around the sun and rotates on its axis. However the earth moves more than just around the sun. In fact, our entire actually orbits around the center of the Milky Way at over 500,000 miles per hour. So why don’t we crash into anything? The answer is that […] Continue reading →
