A Heliocentric system is one in which a sun is at the center.
In the heliocentric model of the solar system, all the planets orbit around the Sun.
The heliopause is the boundary of the heliosphere of the Sun in which the solar wind's density decreases greatly (and its speed also declines)..
A scientist who studies the objects in the sky, including planets, galaxies, black holes, and stars, is called an astronomer.
These days, the terms astronomer and astrophysicist are used interchangeably, to talk about any physicist who specializes in celestial bodies and the forces that affect them..
Astrophile.
Are you a lover of all things celestial? An astrophile is a person who loves astronomy or constantly gazes at the stars..
It can also be a stepping stone to a career in science or engineering.
No matter what you choose to do later in life, astronomy provides you with vital scientific knowledge and transferrable skills..
Mesopotamia.
The earliest sophisticated astronomy arose in ancient Babylonia, in central Mesopotamia, and there are three reasons why it happened there rather than, say, in ancient Greece..
Nicolaus Copernicus is known as the Father of Astronomy.
He completed his first great work titled On the Revolutions of the Heavenly Spheres in 1530..
star, any massive self-luminous celestial body of gas that shines by radiation derived from its internal energy sources.
Of the tens of billions of trillions of stars composing the observable universe, only a very small percentage are visible to the naked eye..
Succinctly put, astrophysics involves the study of physics of astronomy and concentrates on behavior, properties and motion of\xc2 astronomical\xc2 objects out there.
However, modern astronomy includes many elements of motions and characteristics of these bodies and the two terms are often used interchangeably today..
The fruits of scientific and technological development in astronomy, especially in areas such as optics and electronics, have become essential to our day-to-day life, with applications such as personal computers, communication satellites, mobile phones, Global Positioning Systems, solar panels and Magnetic Resonance .
The most widely used programming language by astronomers seems to be Python, though other languages like C/C++, Fortran are also used..
Most of the time, astronomers derive information from an analysis of the light or the motions of celestial bodies, a process that, to the uninitiated, may seem more like sorcery than science.
In fact, astronomy is a challenging science, but not because the universe is inaccessible in the conventional sense..
The earliest sophisticated astronomy arose in ancient Babylonia, in central Mesopotamia, and there are three reasons why it happened there rather than, say, in ancient Greece..
The Julian year, as used in astronomy and other sciences, is a time unit defined as exactly 365.25 days of 86,400 SI seconds each ("ephemeris days").
This is the normal meaning of the unit "year" used in various scientific contexts..

Astronomy is the science that looks up: at stars, at other planets, at solar systems, at galaxies, and at everything else in the universe.
The Ancient Greeks used the word astron for "star," so it only makes sense that astronomy would involve the study or the stars (and other unearthly topics)..
Astronomy is the study of everything in the universe beyond Earth's atmosphere.
That includes objects we can see with our naked eyes, like the Sun , the Moon , the planets, and the stars .
It also includes objects we can only see with telescopes or other instruments, like faraway galaxies and tiny particles..
Astronomy (from the Greek ἀστρονομία from ἄστρον astron, "star" and -νομία -nomia from νόμος nomos, "law" or "culture") means "law of the stars" (or "culture of the stars" depending on the translation)..
astronomy. / (əˈstrɒnəmɪ) / noun. the scientific study of the individual celestial bodies (excluding the earth) and of the universe as a whole.
Its various branches include astrometry, astrodynamics, cosmology, and astrophysics..
The Greeks coined the term astronomy.
The term "astronomy" comes from the ancient Greeks words astron, meaning "star." and nomy, meaning "arrangement." Many words in science and medicine originate from the ancient Greek language.
This is because the Greek laid down the foundations of modern science..
Astronomical and technical terms used frequently in astronomy and space exploration can be difficult to understand like 'celestial pole' or 'constellation' or 'orbital plane'.

A conjunction is when two astronomical objects appear close to each other in the sky.

Constellation In the present day
A constellation is a two-dimensional area in space as defined by the International Astronomical Union (IAU).
Today
There are 88 officially recognized constellations.
Astronomy is “the scientific study of all objects in space” 1 or otherwise defined as “the study of celestial objects and phenomena” 2.
Objects in space include planets
which you can see clearly at different times of the year.
What are some space terms? The following list of words* are terms used in reference to space and the Universe.
An ordinary star such as the Sun at a stable point in its evolution.
A point directly overhead from an observer.
An imaginary belt across the sky in which the Sun
And all of the planets can always be found.
A faint cone of light that can sometimes be seen above the horizon after sunset or before sunrise.
Case in point: syzygy (pronounced SIZ'-a-jee)
which comes from the Greek word for "union." This is the astronomical term for when three or more celestial objects find themselves in a straight line.
Perhaps the most famous example of a syzygy is a total solar eclipse
the moon and Earth all line up.
