Mars, Mercury, galaxies, meteors, ghost particles, wormholes, black wholes, the moon, Neil Armstrong, northern lights, NASA, ESA, dark matter, supernovae, impact crater, polytropic, protostar, dark nebula, Hubble, and you name it. Astronomy and astrophysics has since my childhood been something that has interested me. Being able to observe celestial bodies- Seeing Earth from space and be in a weightless state would be fascinating. It has always been my dream to become an astronaut. I would greatly appreciate your vote.
