The OMICS journal of Astrophysics deals with the study of celestial objects and their properties. The study sheds light on various astronomical phenomenon and the underlying principles of electromagnetism, thermodynamics, statistical mechanics, relativity, nuclear physics and quantum mechanics; and overall domain of aerospace technologies.

The field also complements other studies like rocket sciences. The branch of theoretical physics creates various models and seeks to establish paths that are covered by spatial bodies. The topics studied thereby include cosmic rays, general relativity and physical cosmology. Several concepts like Big Bang, Lambda-CDM model, cosmic inflation and dark energy are some of the hypotheses to be proved.

Prior to the 6th century, astronomy and physics were linked and became empirical and mathematical instead of philosophical. The concept of modern aerospace evolved after George Cayley proposed a flying body with a fixed wing and tails that would be vertical and horizontal. In 1981, space shuttle Columbia began as the first manned mission. Astrophysics involves the trajectory, path of rockets and the characteristics of the fuel used for a rocket engine.

Telescopes and detectors on satellites explore new wavelength ranges, while new automated means to infer results based on data, for the comparative study of e.g. millions of galaxies.

Cold War and other rivalries based on political rivalry on the earth’s surface have been accompanied by advanced research in aerospace. As part of NASA’s Constellation Program, the Crew Exploration Vehicle (or CEV) was the first unit to send explorers to moon, who would later head to Mars.

Astronomy is mostly based on observation rather than experimentation. Since the observation time is much smaller than the typical time scale for the evolution of astronomical objects, we see just a snapshot of the universe. Nevertheless it is possible to reconstruct, e.g., the evolution of stars by studying large samples. On the extragalactic scales, we can use that looking far away means implies studying the history of the current speed of light, while on the cosmological scale we can use relics formed soon after the Big Bang as testimonies for the state of the early universe.

Computational astrophysics is used to solve mathematical problems related to the discipline using advanced computing techniques. Computational methods are required to calculate the propagation of light through the outer layers of a star, cross section of photons and studies that are relevant to the astrophysics discipline; and the ionic balances in the outer space. The construction of such stellar atmosphere models share many challenges with radiation transfer problems in other systems such as planets, accretion disks, and the interstellar medium.

Astrophysics research involves the studies of the celestial object put into motion. Monte Carlo algorithms are also used for numerical analysis for complex mathematical calculations underlying the fields that involve trajectories of massive objects that are either out into the earth’s orbit or the outer space.

OMICS aerospace journal studies provides the latest insights into the advanced research in the respective and complementary fields.
