Our galactic centre cannot be seen in optical light due to heavy obscuration from foreground stars and interstellar matter; we can only see about a tenth of the way toward the centre.

Lesson 3: Calculating distances to stars

It is a rather simple principle; if a star is close by then it will appear bright, and if the star is far away i ...

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.
