The Limitations of Light Speed
As we all (hopefully) know, nothing can travel faster than the speed of light. Light-speed is the universal speed limit, and no matter or energy can move faster than it, including radio signals or other forms of communication. This limitation makes me rather pessimistic about deep-space exploration. The Milky Way Galaxy is massive, at tens […] Continue reading
The Arecibo Message
The Arecibo Observatory was constructed in 1963 as the world’s largest and most sensitive radio telescope. Sitting in a naturally spherical valley in Puerto Rico, this telescope looks decidedly different from the pristine optics associated with optical telescopes such as the Keck Observatory or the Hubble Space Telescope. This is because the Arecibo Observatory peers … Continue reading The Arecibo Message → Continue reading
The Largest Telescope in the World
Larger telescopes allow for better angular resolution, which allows for us to discern between two light producing objects that are close together. Therefore, telescopes are ever increasing in size to get better and better images. Beating out telescopes called “Very Large Telescope” and “South African Large Telescope”, the Arecibo Radio Telescope in Puerto Rico is […] Continue reading
