Astronomy is the general field of natural sciences related to celestial objects, including the Solar System, galactic, and extragalactic objects. Most students enrolled in this field work in this area.
Astrophysics
is the study of objects outside the solar system, such as supernovae, nebulae, and black holes.Space physics
, on the other hand, is the term given to a specific field of research that studies plasmas within our solar system, which includes topics such as planetary physics and solar physics.As you learn each of these topics, you can also begin to establish links between them, which should also strengthen your general understanding of space physics. Companies and countries invest a lot of time, labor, and money sending satellites into space to perform a variety of tasks. This radiation is caused by the space-time fabric that makes up the Universe itself; it's like background noise. By studying the spectra of stars, astrophysicists were also able to determine the speed at which they are approaching or moving away from Earth.
Let's now take this opportunity to analyze each topic of space physics and find out what each one involves. At NASA, the objectives of astrophysics work are to discover how the universe works, explore how it began and evolved, and search for life on planets around other stars, according to the NASA website. Fifty years later, Einstein's famous equation E%3Dmc2 gave astrophysicists the first clue as to what that energy source could be (although it turns out that gravitational collapse plays an important role). For now, you just need to know and use the term space physics and keep in mind that astrophysics is a field of research that essentially means the same thing.
The first ideas about the nature of stars emerged in the mid-19th century thanks to spectral analysis, an essential pillar of space science that consists of observing the specific frequencies of light that certain substances absorb and emit when heated. This added to the body of evidence that supported the (then) surprising conclusion that the heavens and Earth are subject to the same physical laws. As nuclear physics, quantum mechanics, and particle physics grew in the first half of the 20th century, it became possible to formulate theories about how nuclear fusion could power stars. Outside of GCSE physics, space physics focuses more on the magnetic fields of planets, on how these magnetic fields interact with the solar wind and on how these changes can affect orbiting satellites.
Astrophysics creates physical theories of small to medium sized objects and structures in the universe. It also studies phenomena such as supernovae explosions, gamma ray bursts, quasars, and active galactic nuclei. Space physics is a fascinating field that combines astronomy with other sciences such as mathematics and chemistry. It involves studying plasmas within our solar system such as planetary physics and solar physics. It also looks at how magnetic fields interact with solar winds and how these changes can affect orbiting satellites.
Astrophysics is a related field which studies objects outside our solar system such as supernovae, nebulae and black holes. It also creates physical theories about small to medium sized objects in space. By understanding both space physics and astrophysics we can gain a better understanding of our universe and its many mysteries. With advances in technology we can now explore further than ever before into space.
