A quasar (believed to be a galaxy in formation with a super-massive black hole at its center) is a pointlike object that has tremendous energy output, is very distant from the Earth, and has a large redshift. Its speed can be measured from Doppler-shift measurements of the light it emits. A certain quasar recedes from the Earth at a speed of 0.55 c. (a) How far away is it? (b) Assuming that the quasar has moved with the speed 0.55 c ever since the Big Bang, estimate the age of the Universe. | Nu

AstroScience | Space on Instagram: "📌 Pulsar vs Quasar 🔥🚀 Pulsars and Quasars are two remarkable astronomical phenomena that shed light on the extreme conditions and processes within our universe. Pulsars are highly magnetized neutron stars that emit beams of electromagnetic radiation. These emissions are observable as regular pulses due to the star's rapid rotation and magnetic orientation. Pulsars serve as invaluable tools for studying various aspects of astrophysics, such as the properties
