... It makes intuitive sense that the farther a star is from Earth, the longer it takes light from the star to reach Earth. The star Polaris is 400 ly from Earth. In other words, it takes light from Polaris 400 years to reach Earth. The light that we see when we look at Polaris is 400 years old. We are ...

Corvus (constellation)
Corvus is a small constellation in the Southern Celestial Hemisphere. Its name comes from the Latin word ""raven"" or ""crow"". It includes only 11 stars with brighter than 4.02 magnitudes. One of the 48 constellations listed by the 2nd-century astronomer Ptolemy, it remains one of the 88 modern constellations. The four brightest stars, Gamma, Delta, Epsilon, and Beta Corvi from a distinctive quadrilateral in the night sky. The young star Eta Corvi has been found to have two debris disks.
