Which physical science deals with stars and planets
Our Earth has molten lava, icy mountain peaks, steep canyons and towering waterfalls. Earth scientists study parts of the Earth as big as continents and as small as the tiniest atom. In all its wonder, Earth scientists seek to understand the beautiful sphere on which we thrive Figure 1. Because the Earth is so large and science is so complex, Earth scientists specialize in studying just a small aspect of our Earth. Since all of the branches are connected together, specialists work together to answer complicated questions.
Geology is the study of the solid matter that makes up Earth. Anything that is solid, like rocks, minerals, mountains, and canyons is part of geology.
Geologists study the way that these objects formed, their composition, how they interact with one another, how they erode, and how humans can use them. Geology has so many branches that most geologists become specialists in one area. For example, a mineralogist studies the composition and structure of minerals such as halite rock salt , quartz, calcite, and magnetite Figure 1.
A volcanologist braves the high temperatures and molten lava of volcanoes. Seismologists study earthquakes and the forces of the Earth that create them. Seismologists monitor earthquakes worldwide to help protect people and property from harm Figure 1. There are geologists who only study the Moon. Some geologists look for petroleum, others are specialists on soil. Geochronologists study how old rocks are and determine how different rock layers formed.
There are so many specialties in geology that there is probably an expert in almost anything you can think of related to the Earth Figure 1. Oceanography is the study of everything in the ocean environment.
Most of that water is found in the oceans. Recent technology has allowed us to go to the deepest parts of the ocean, yet much of the ocean remains truly unexplored. Some people call the ocean the last frontier. But it is a frontier already deeply influence by human activity.
As the human population gets ever bigger, we are affecting the ocean in many ways. Populations of fish and other marine species have plummeted because of overfishing; contaminants are polluting the waters, and global warming caused by greenhouse gases is melting the thick ice caps.
According to the Oxford Dictionary, astronomy is defined a the branch of science that deals with celestial objects, space, and the physical universe as a whole. In other words, astronomy deals with all bodies in space such as stars, planets, galaxies, etc. There are many different branches of astronomy such as astrophysics deals with the physics of the universe or planetary science deals with our local Solar System.
Astronomy is the study of space and stars are in space, so astronomy deals with the study of stars. Astronomy is the study of planets and stars, among many other things. Astronomy is a natural science that deals with the study of celestial objects such as stars, planets, comets, nebulae, star clusters and galaxies and phenomena that originate outside the atmosphere of Earth such as the cosmic background radiation.

The Muslim Empire group charted the stars and planets. Acorrding to modern science, yes. The branches of physical science includes astronomy, chemistry, physics, and earth sciences. Astronomy studies stars and planets. Chemistry studies the chemical makeup of the earth.
Physics studies how objects move in space. Earth science encompasses the study of Earth itself. Yes and no: astrophysics deals with the physics of the universe, which includes celestial objects such as stars, galaxies, planets, and exoplanets.
Stars suns generate light; planets reflect light. Stars are masses of burning, explosive gases; planets are solids. Planets orbit stars and not the other way around. Stars have powerful physical effects on their orbiting planets; the reverse is generally not true. Planets orbit stars. Astronomy is the study of stars, planets, and the other things in space, while earth science is the study of the Earth and its landscape.
The two fields complement each other, with theoretical astronomy seeking to explain the observational results, and observations being used to confirm theoretical results. Amateur astronomers have contributed to many important astronomical discoveries, and astronomy is one of the few sciences where amateurs can still play an active role, especially in the discovery and observation of transient phenomena.
The most frequently studied star is the Sun, a typical main-sequence dwarf star of stellar class G2 V, and about 4. The Sun is not considered a variable star, but it does undergo periodic changes in activity known as the sunspot cycle.
The astrophysics of stars has been determined through observation and theoretical understanding; and from computer simulations of the interior. When destabilized, cloud fragments can collapse under the influence of gravity, to form a protostar. A sufficiently dense, and hot, core region will trigger nuclear fusion, thus creating a main-sequence star. Reference Terms.
Astronomy is one of the oldest sciences. The study of stars and stellar evolution is fundamental to our understanding of the universe. That includes space telescopes like the Hubble Space Telescope. People very often confuse astronomy with astrology.
Observational astronomy can be traced back to Ancient Egypt and Mesopotamia as far back as 3, B. Modern astrologers attempt to do something similar, making predictions about human lives based on pseudoscience.
Astrology is not a science. In the past century or so, astronomy has been broadly split into two camps — observational astronomy using telescopes and cameras to collect data about the night sky and theoretical astronomy using that data to analyze, model and theorize about how objects and phenomena work.
