=Astronomy is a scientific study of matter in outer space, especially the positions, dimensions, distribution, motion, composition, energy, and evolution of celestial bodies and phenomena. Astronomy is a science which is studied by astronomers. They study galaxies, stars,constellatIons, absalutely everything about space. Astronomers use several type of instruments or tools to perfom their field of study. They use telescopes, computers, cameras which capture many amazing photos from outer space. Most of their research is perfom in NASA labs. The expected salary for a typical astronomer in the United States is $97,000. This line of study may require an advanced degree and at least 2-4yrs. of direct experience in this field. Large telescopes have proven useful in taking spectra of the optical counterparts of gamma-ray bursts, proving they are very far away. =  ___

Biology is the study of humans, plants, animals, and the environment, also biology is a form of life science. There are many different kinds of biologists; there can be marine biologists, microbiologists, zoologists, and many more. Biologists use microscopes as a tool to help them study an object or many objects. Most Biologists become biology teachers mostly at high schools, but some study in a lab. Biologists have a salary range anywhere from $55,727 - $90,178 a year depending on how much experience they have. Biologists have an important job, because they help us cure diseases for humans, and they can even see if a certain species of animals are going to become extinct, wouldn’t you want to know that information? back round there is a microscope **<**study, fish, and other sea creatures. used to magnify the item or items that he is studying.

Astrophysics is a branch of physics and astronomy. It invovles the physics of the universe such as glaxacies, stars, and planets. People wo work on astrophysics need special tools such as radio telescopes. Astrophysicians may find jobs places such as universities and observatories. Their salary is from $30,000-$92,430. A famous person that studied astrophysics is Nicolaus Copernicaus. He revived heliocentism in the 16th century.


 * chemistry studies chemicals and substances.It is under the branch of physics.Sience and medicine are commonly seen in the field of study.Breaker,Bunsen burner,etc. are equipment used in that process.There are many career opportunities such as Aerospace,which make $38,553-$55,911 in salary range.There are many importants to this current event such as existence of life which is based on chemical reaction.**
