Limitations of Gravitational Slingshots in our Solar System

The use of gravity assist has been an integral part of space exploration. Gravitational slingshots have been used time and time again to send spacecraft to areas that would be impossible to get to otherwise by providing the spacecraft with increased speed. Accordingly, spacecrafts are able to get places faster and use less fuel. (Voyager […] Continue reading Continue reading

Making the Jump to Light Speed

Chapter 1 of Astronomy: The Solar System served as a HUGE (seriously though) reminder as to how small and insignificant we are, and how very very very infinitesimally small the corner of the universe we’ve explored actually is. I’m a big Star Wars fan, and looking at that world from the perspective of astronomy class, […] Continue reading Continue reading

The Speed Limit of the Universe

58,536 km/h. That’s the speed of the fastest ever man-made vehicle: the New Horizons space probe. Though this may seem like an unfathomable feat to the layperson, there’s something that can travel even faster than that by five orders of magnitude. Light is the current “speed limit of the universe.” It travels at 3 x 108  m/s or 1 […] Continue reading Continue reading

One Long Trip

When we look up at the sky during the night, it can feel comforting that instead of being surrounded by darkness, we see the bright twinkles of stars all around us. Though this might make us feel like we are not simply on a rocky planet hurtling through space far from everything else, this is not […] Continue reading Continue reading

Is Light The Limit?

Albert Einstein once theorized that speed of light serves as somewhat of a global speed limit. It is assumed that nothing in the universe is capable of traveling faster than the speed of electromagnetic radiation. According to his observations, this makes sense. How could something composed of atoms of mass travel faster than a beam […] Continue reading Continue reading
