Astrophysics is a branch of space science that applies the laws of physics and chemistry to seek to understand the universe and our place in it.
Astronomy is the scientific study of all objects in space. The word comes to us from the ancient Greek term for "star law." Astrophysics, which is part ofastronomy, goes a step further and applies thelaws of physicsto help us understand the origins of the universe and the objects in it....
What is the nebular hypothesis of planet formation? When was the heliocentric model accepted? Why is the Sun fourth in the Ptolemaic planetary system? What is the standard unit of period in astrophysics? What is an astronomical unit used for?
Over the following decades, astronomers, aided by the improvements in telescope technology gradually grew the catalogs of stellar distances using the parallax method. In 1924, American astronomer Frank Schlesinger published a catalogue with the parallaxes of almost 2,000 stars, probing stellar distances...
