Astrophysics teacher | Experienced educator in USA
I hold a degree in Astrophysics from Portland State University. My passion lies in unraveling the mysteries of the cosmos and sharing my knowledge with students. With a deep understanding of celestial mechanics and stellar phenomena, I offer expert guidance in physics, mathematics, and astronomy. Whether it's explaining the dynamics of black holes or solving complex equations, I'm dedicated to fostering a deeper appreciation for the wonders of the universe. Join me on a journey through the cosmos, where every question leads to a new discovery.
Questions
How can we see supernova remnant G1.9+0.3? If it is estimated to be about 25,000 light years away and now NASA says that it is about 140 years old, how can we even observe it? Wouldn't it still appear as a star to us for the next 24,860 years or so?
