An astronomer is a scientist in the field of astronomy who studies stars, planets, moons, comets and galaxies, as well as many other celestial objects — either in Observational astronomy, in analyzing the data or in theoretical astronomy. A related but distinct subject, cosmology, is concerned with studying the Universe as a whole. An astronomer researches the world beyond Earth.
Historically, astronomy was more concerned with the classification and description of phenomena in the sky, while astrophysics attempted to explain these phenomena and the differences between them using physical laws. Today, that distinction has mostly disappeared and the terms "astronomer" and "astrophysicist" are interchangeable. Professional astronomers are highly educated individuals who typically have a PhD in physics or astronomy and are employed by research institutions or universities. They spend the majority of their time working on research, although they quite often have other duties such as teaching, building instruments, or aiding in the operation of an observatory.
The Astronomer (Seginn Gallio) is a fictional character, an ancient alien appearing in the Marvel Comics universe. He is one of the Elders of the Universe. His first appearance was in Silver Surfer (Vol.3) #4.
Long ago, the Astronomer chose to dedicate himself monomaniacally to chronicling the slow evolution of the stars and galaxies themselves. He long ago lost interest in living beings.

The Astronomer is an old man (born in 1925), who has thinning white hair, wears glasses and is best described as "mole-like"; he is also noted as having a disproportionately large head, the upper part of which enlarges further when he is fully empowered. He has wiped his own memory of all events prior to becoming the Astronomer. The Astronomer usually uses a wheelchair, although the proper use of his Ace powers can allow him to walk. The Astronomer practices a horrific form of death magic, gaining immense energy through the ritualistic slaying of his victims (usually young women). He greatly enjoys having Demise slowly kill the victims, taking their suffering from projected death as his energy source.
