The Royal Institution Christmas Lectures: 48, Part OnePremieresSaturday December 9th at13.30 UTCLanguageEnglishAstrophysics — Unwrapping the Universe. Let’s dive into world of space science!
Astrophysics — The branch of astronomy which concerns itself with the physical and chemical composition, dynamics processes taking place in cholesterol bodies and cosmic phenomena(not on Earth) observed beyond the Earth’s atmosphere. It bridges physics with mathematics under an effort to study the fundamental forces that structure the universe, from black holes through galaxy formation. Astrophysics therefore deals with changing the topics in conceptually Inzenie of quantum physics to address astrophysics subjects and connect theoretical physicists together with observational astronautics factories.
Cosmology -The Science That Studies the Beginning of the Universe
Astrophysics is the study of stars, planets and how these link into a universe which it shares with another subject cosmology. The most mundane explanation of course is the one in common practice at this time; the Big Bang, where it required everything to have popped out from a point and has been expanding for some 13.8 billion years. Among other things, astrophysicists go in search of the cosmic microwave background —- a faint glow that lingers from an early stage with 378 thousand years of existence and shows how it formed and evolved into what we see nowadays.
The Life Cycle of Stars and Stellar Evolution in Space Science
Astronomical Importance: Stars are a very important part of the cosmos and cosmic processes as these stars act like building blocks of the universe. The stars form as the gas and dust within these nebulae collapse due to gravity. The ultimate fate of a star—white dwarf, neutron star, or black hole—is primarily dictated by its mass. This process is called nucleosynthesis and as stars form, evolve, age and dissipate at end-of-life into space they do so openly releasing heavy elements including carbon and oxygen which enriches the interstellar medium eventually leading to environments conducive to life emerging.

At one end of stellar evolution sit black holes and neutron stars. This is gravitation in its extreme, and the most compelling evidence that black holes actually exist which puts to test our understanding of General Relativity — fundamental theory describing gravity by very violent experiments with extreme states of matter. A teaspoon of material produced by the explosion of a supernova will get so heavy when it forms into a neutron star, that from Earth its weight is described in billions—as you can see, perfect conditions for seeing at high-density physics.
The Structure of the Universe in Space Science: Galaxies, Dark Matter
Galaxies are gravitationally bound systems of stars, gas, and dark matter that form part of the large-scale structure in the universe. The Milky Way Galaxy, of which our Solar System is a part of; has only one hundred billion. The formation, evolution, and interaction of galaxies is the purview of astrophysicists—those who study the universe at its largest scales. The researchers also looked at the impacts of dark matter on galaxy dynamics, and how dark energy is causing the universe to expand faster.
The exoplanets are discoveries of planets in other solar systems, which have revitalized efforts to search for life beyond Earth. For astrobiologists that search for life beyond our solar system, oxygen and methane in a planet’s atmosphere could be signs of extraterrestrial biology.
In the search to determine if life exists somewhere other than on Earth, the discipline of astrobiology combines astronomy with biology and chemistry. Observational methods are performed to help the theoretical work in astrobiology, and these observations include everything from radio waves to gamma rays with telescopes that get a perspective of distant celestial phenomena. A Bottom Up Approach to AstrophysicsPart II: Contemporary Challenges and Future ExplorationThose are deep challenges facing astrophysics today: dark matter, 27%, and dark energy together constitute the remaining 95% of the mass-energy content in our Universe. The discovery of gravitational waves by LIGO observatory in 2015 is kind of a new era for astronomy and it also provides a new window to observe the universe using Gravitational signals. Future projects, like the James Webb Space Telescope would even peer beyond the first stars and galaxies. These results are a checkpoint for developing more insight of the universe and our position in it.
