My name is Nada and I’m studying in natural sciences to complete in an astrophysicist studies, An astrophysicist is a scientist who uses advanced physics and mathematics to study the universe and understand how celestial objects behave and evolve. This career naturally follows studies in physics and mathematics, as it requires strong analytical and problem-solving skills. After completing a Bachelor’s degree in physics and mathematics, students usually pursue a Master’s degree specializing in astrophysics, cosmology, or space science. A PhD is generally required to become a professional astrophysicist. Doctoral research focuses on a specific topic such as black holes, galaxy formation, dark matter, or stellar evolution. Researchers often work with international institutions or space agencies like NASA or European Space Agency. Wright bellow you will find A glossary that list’s the terms with their definition to help you understand a little bit more about the language of an astrophysicist.
black hole
noun
Region where gravity prevents light escape.
Example: Neither can dark matter be simply hidden within vast numbers of black holes or neutron stars, as a BLACK HOLE large enough to hold the required amount of dark matter would produce and emit numerous x-rays that are easy to detect.
fr: trou noir
cosmology
noun
Study of the origin and evolution of the universe.
Example: Another interpretation advocated by some scholars is that the Way of Seeming is 'an account of Pythagorean COSMOLOGY', a world composed of elements 'distinct from one another- one form the bright fire of flame'; and the other 'as impenetrable night' which would entail a discontinuous reality.
fr: cosmologie
dark energy
noun
Energy causing accelerated universe expansion.
Example: It is believed that "stars make up less than 1% of the universe's mass; all the loose gas and other forms of matter, less than 5%" (1), and the rest is made up of dark matter and DARK ENERGY, 25% of which is dark matter.
dark matter
noun
Invisible matter affecting galaxy motion.
Example: Therefore, there must be something that is pulling these stars and this has been called DARK MATTER, even though it has never been discovered.
fr: matière noir
exoplanet
noun
Planet orbiting a star outside our solar system.
Example: an exoplanet orbits a distant star
fr: exoplanet
galaxy
noun
Massive system of stars, gas, and dark matter.
Example: Not only did Hubble observe this characteristic redshift from a single GALAXY, but from the vast majority of galaxies he was measuring.
fr: galaxie
gravity
noun
Force attracting masses toward each other.
Example: Therefore is GRAVITY measured by body count?
fr: gravité
nebula
noun
Cloud of gas and dust in space.
Example: The Crab NEBULA's bell-shaped appearance in the X-ray image
fr: nébuleuse
nuclear fusion
noun
Energy process powering stars.
Example: nuclear fusion power the sun
fr: fusion nucléaire
orbit
noun
Path of an object around another body.
Example: Bohr said that the electrons 'in ORBIT' around the nucleus of an atom stayed in place because they could not radiate energy continuously.
fr: orbite
quantum mechanics
noun
Physics of particles at microscopic scales.
Example: The spin cannot align with the magnetic field to minimise its energy because magnetic spin is quantised, and so to change angles (and thus energy) by amounts that represent an energy less than a single quantum is forbidden by QUANTUM MECHANICS.
fr: mécanique quantique
relativity
noun
Einstein’s theory describing gravity and spacetime.
Example: Black holes arise in General RELATIVITY, a classical theory, but in order to fully understand them, quantum effects must be taken into account as they undergo a runaway gravitational collapse, resulting in a singularity at their centre.
fr: relativitée
spacetime
noun
Four-dimensional combination of space and time.
Example: Spacetime bends around massive objects.
fr: espace temps
spectroscopy
noun
Study of light to analyze celestial objects.
Example: Dynamical structure of the hinge region of immunoglobulin G as studied by 13C nuclear magnetic resonance SPECTROSCOPY
