As it is about the physics of the whole universe and how everything in it works, astronomers need to have a good knowledge of physics and maths, and chemistry is pretty helpful too. You would need to get good grades in your GCSEs and A-levels or Highers if you want to go on and study further.
How do stars relate to chemistry?
Stars form when huge amounts of gas and dust collapse under their own gravitational force. The majority of this gas is hydrogen which is the basic fuel that stars use to create energy. During hydrogen fusion, protons (nuclear subatomic particles) are combined in order to create helium.
How does chemistry relate to the universe?
1 Answer. Chemistry defines how the elements in the Universe formed and how the transition took place from lighter to heavier elements.
Is there chemistry in space?
Observations with radio waves carried out in the seventies proved that interstellar space is not only full of hydrogen and dust, but also contains complex chemical compounds, or gaseous molecules, such as water (H20), ammonium (NH3) and methanol (CH3OH).
Is chemistry important for astrophysics?
Answers and Replies. Chemistry is definitely used in astrophysics. In the U.S., if someone plans on getting a Bachelors of Science with a focus in astrophysics, they will most likely need to take at least a first year general chemistry course and maybe even a chem.
Do you use chemistry in astrophysics?
Astrophysics is a branch of space science that applies the laws of physics and chemistry to seek to understand the universe and our place in it. The field explores topics such as the birth, life and death of stars, planets, galaxies, nebulae and other objects in the universe.
What chemical reactions happen in space?
Chemical reactions in space can occur in the gas phase (top), as part of gas–grain interactions (lower left), through exposure to ionizing radiation (energetic photons and/or particles, lower middle), and via thermal cycling (lower right).
How do we know what stars are made of chemistry?
The most common method astronomers use to determine the composition of stars, planets, and other objects is spectroscopy. Today, this process uses instruments with a grating that spreads out the light from an object by wavelength. This spread-out light is called a spectrum.
Are stars formed from a chemical reaction?
The process begins when a star forms from a collapsing hydrogen cloud. The gravitational pressure at the star’s core generates heat, which ignites a thermonuclear fusion reaction that converts the core’s hydrogen into helium. This process, called “nucleosynthesis,” continues until the core’s hydrogen is exhausted.
How does chemistry help in the development of space research and electronics?
Answer. Chemistry helps in development of space research and electronics by modifying materials available in nature and synthesizing materials which are not available in nature.
Is astronomy harder than chemistry?
Astronomy is not necessarily harder than chemistry, but it’s more multidisciplinary and therefore has more prerequisites for advanced classes. It’s actually close to impossible to be an astronomer without doing lots of chemistry-related subjects as well.
Is chemistry a quantum mechanics?
Quantum chemistry, also called molecular quantum mechanics, is a branch of physical chemistry focused on the application of quantum mechanics to chemical systems, particularly towards the quantum-mechanical calculation of electronic contributions to physical and chemical properties of molecules, materials, and …
How is physics used in astronomy?
Physics is used in the design of instruments, the interpretation of the data the instruments produce, and finally in the construction of the grand theories which explain the evolution of stars, galaxies, and the universe (or the earth!).
What is difference between astronomy and astrophysics?
For example, Astronomy can be described as the study of the universe beyond the Earth’s atmosphere, while Astrophysics can be defined as a branch of Astronomy which concentrates on the physical processes associated with the entities that comprise the universe.
How do gasses react in space?
Gases (like air) expand to fill their containers, and in space there is no container, so it would simply expand until it is the same density as space itself.
Does carbon exist in space?
Much of the carbon in space is believed to exist in the form of large molecules called polycyclic aromatic hydrocarbons, or PAHs. Since the 1980s, evidence has indicated that these molecules are abundant in space, but they have not been directly observed.
How is the chemical reaction affected by gravity?
A change in gravity, form 1G to 0G, will not have any effect on reaction rates: the interactions among molecules, at molecular scales are MUCH stronger than the gravity forces. You can do some simple calculations to check this.
How do scientists know what elements are in stars?
This type of study is called spectroscopy. The science of spectroscopy is quite sophisticated. From spectral lines astronomers can determine not only the element, but the temperature and density of that element in the star. The spectral line also can tell us about any magnetic field of the star.
What is the most common element found in stars?
No one mechanism can account for all the elements; rather, several distinct processes occurring at different epochs during the late evolution of a star have been proposed. After hydrogen, helium is the most abundant element.
What chemicals are stars made of?
Stars are made of very hot gas. This gas is mostly hydrogen and helium, which are the two lightest elements. Stars shine by burning hydrogen into helium in their cores, and later in their lives create heavier elements.
What is the most important force in astronomy?
Gravity is one of the fundamental forces in the Universe. Although gravity is the weakest of all the forces in the Universe, it is the most important force in the study of astronomy. Originaly defined by Newton, and refined by Einstein, gravity is essentially the natural force of attraction between any two objects.
What is it called when a star is born?
It is called a protostar. Under what conditions do astronomers technically say a star has been born? [ 1 mark] If there is enough gas and dust for the temperature to become hot enough for nuclear reactions to start, the protostar will then technically be called a star.
Have we ever witnessed a star being born?
Summary: Astronomers have glimpsed what could be the youngest known star at the very moment it is being born. Not yet fully developed into a true star, the object is in the earliest stages of star formation and has just begun pulling in matter from a surrounding envelope of gas and dust.

What is the hardest science subject?
Physics. Generally, physics is often deemed to be the hardest of all the sciences, especially as an A level qualification. Physics involves a lot of complex maths content – an aspect that most students struggle with.
