Extragalactic astronomy is the branch of astronomy concerned with objects outside the Milky Way galaxy. In other words, it is the study of all astronomical objects which are not covered by galactic astronomy.
Astronomy is a natural science that studies celestial objects and the phenomena that occur in the cosmos. It uses mathematics, physics, and chemistry in order to explain their origin and their overall evolution. Objects of interest include planets, moons, stars, nebulae, galaxies, meteoroids, asteroids, and comets. Relevant phenomena include supernova explosions, gamma ray bursts, quasars, blazars, pulsars, and cosmic microwave background radiation. More generally, astronomy studies everything that originates beyond Earth's atmosphere. Cosmology is a branch of astronomy that studies the universe as a whole.
General relativity is a theory of gravitation that was developed by Albert Einstein between 1907 and 1915, with contributions by many others after 1915. According to general relativity, the observed gravitational attraction between masses results from the warping of space and time by those masses.
Cosmic dust – also called extraterrestrial dust, space dust, or star dust – is dust that occurs in outer space or has fallen onto Earth. Most cosmic dust particles measure between a few molecules and 0.1 mm (100 μm), such as micrometeoroids and meteoroids. Cosmic dust can be further distinguished by its astronomical location: intergalactic dust, interstellar dust, interplanetary dust, and circumplanetary dust. There are several methods to obtain space dust measurement.

Joan T. Schmelz is the associate director for science and public outreach at the Stratospheric Observatory for Infrared Astronomy (SOFIA) for the Universities Space Research Association (USRA). Previously, Schmelz was the deputy director of Arecibo Observatory and the director of USRA Operations at Arecibo from 2015 through 2018. Before joining USRA, Schmelz was an NSF program director in the Astronomical Sciences Division, where she oversaw the Astronomy & Astrophysics Postdoctoral Fellowship program, and a professor of physics at the University of Memphis from 1996 to 2017. Schmelz's research focus is heliophysics, specifically investigating the coronal heating problem as well as the properties and dynamics of the solar atmosphere. She uses spectroscopic and image data in the X-ray and ultraviolet wavelength ranges obtained from NASA satellites and rockets. She has published over 80 refereed scientific journal articles and authored three books.
Heather A. Knutson is an astrophysicist and professor of planetary science at California Institute of Technology in the Division of Geological and Planetary Sciences. Her research is focused on the study of exoplanets, their composition and formation.
The School of Music is an academic division of the University of Missouri in Columbia, Missouri. Its focus is the study of music, awarding baccalaureate, master's, and doctoral degrees as part of the College of Arts and Science. The institution's programs encompass composition, performance, conducting, music education, music history, musical theatre and musicology. Established in 1917 as the Department of Music, the school continues to play a prominent role in the cultural life of Missouri and is located in the Sinquefield Music Center, on the university's flagship campus in Downtown Columbia. The Fine Arts Building also houses classrooms, studios, and a recital hall. Its major performance venues are Jesse Hall, the Missouri Theatre, and Whitmore Recital Hall. The Missouri Tigers marching band, Marching Mizzou, performs at Faurot Field for Southeastern Conference football games. The school's ensembles have performed worldwide and can be heard weekly on the university's own KMUC 90.5 FM Classical, Mid-Missouri's classical music radio station. Alumni include singers Sheryl Crow and Neal Boyd, Canadian Brass founder Gene Watts, and jazz artist Mike Metheny.
