5 types of astronomy
Astronomers use light and the different wavelengths or colors at which it radiates to uncover the mysteries of the universe.
Each point, or pixel, in an astronomical image may represent temperature, a wavelength of light, or the intensity of the signal.
Each color brings into view an otherwise invisible universe..
5 types of astronomy
Astronomers, unlike astronauts, do not go into space.
Astronomers are the people who observe objects in space from the safety of Earth.
Instead of reaching outer space through rockets, astronomers use their handy telescopes to gaze at the thousands of different objects in the sky..
5 types of astronomy
Branches of astronomy.
Astrobiology – studies the advent and evolution of biological systems in the universe.
Astrophysics – branch of astronomy that deals with the physics of the universe, including the physical properties of celestial objects, as well as their interactions and behavior..

Astronomy branches
Astronomy is a natural science that studies celestial objects and phenomena.
It uses mathematics, physics, and chemistry in order to explain their origin and evolution..
How did ancient astronomy work?
They have looked at the movement of the stars and the changes of the Sun and Moon.
Using what was known about the positions of stars, eclipses, and Moon phases star maps were made.
This information was used to make calendars and measure time.
It was very useful for planning when to plant crops, or for finding your way..
How did astronomy happen?
Astronomy is the oldest of the natural sciences, dating back to antiquity, with its origins in the religious, mythological, cosmological, calendrical, and astrological beliefs and practices of prehistory: vestiges of these are still found in astrology, a discipline long interwoven with public and governmental astronomy .
How do astronomers know how far away something is?
The Parallax Angle -- How Astronomers Use Angular Measurement to Compute Distances in Space.
The parallax angle is the angle between the Earth at one time of year, and the Earth six months later, as measured from a nearby star.
Astronomers use this angle to find the distance from the Earth to that star..
How does astronomy work?
Astronomers study planets, stars, and other celestial bodies.
They use ground-based equipment, such as optical telescopes, and space-based equipment, such as the Hubble Space Telescope.
Some astronomers study distant galaxies and phenomena such as black holes and neutron stars..
How does astronomy work?
Observational astronomy is focused on acquiring data from observations of astronomical objects.
This data is then analyzed using basic principles of physics.
Theoretical astronomy is oriented toward the development of computer or analytical models to describe astronomical objects and phenomena..
How does distance work in space?
A common method for measuring distance in space is to measure how far light travels in one year: known as a lightyear, which is around 9.5 trillion km.
If you want to be precise, the IAU regards a year as 365.25 days, making a lightyear 9,460,730,472,580,800m.Mar 27, 2021.
How was astronomy first used?
Monitoring the motions of stars and planets in the sky was the best tool to track time, which was fundamental for agriculture, religious rituals and navigation.
The first documented records of systematic astronomical observations date back to the Assyro-Babylonians around 1000 BCE..
What do astronomers work for?
Work environments for astronomers vary.
They can work as professors or research staff at universities, while others may work in government-supported observatories and labs.
Some work for private companies, such as aerospace firms.
Most astronomers have full-time positions.Feb 3, 2023.

Where do astronomy work?
Most astronomers work in offices and occasionally visit observatories, buildings that house ground-based telescopes used to observe natural phenomenon and gather data.
Some astronomers work full time in observatories..
Where does astronomy work?
The majority of astronomers are employed by universities, but there are a few government and private institutions (such as observatories) that hire astronomers.
Permanent positions in both astronomy research and outreach can be competitive, so you may have to consider moving internationally to pursue this career..
Why do astronomers work?
Professional astronomers are motivated by curiosity and a deep desire to understand some of the grandest and most beautiful phenomena in the universe, as well as a desire to share these wonders with others..
How to become an astronomer
1Complete an undergraduate science degree, with a major in astronomy, physics or astrophysics.
2) Astronomy can be competitive.
3) Stay up-to-date with industry changes and network with likeminded professionals through institutions like the Astronomical Society of Australia (ASA).- According to their estimates the universe is 13.7 billion years old with an uncertainty of 200 million years.
The WMAP value of Ho is 71 \xb1 4 km/s/Mpc which is in agreement with the HST key project.
Astronomers determine properties of the universe by fitting the WMAP data with models.
